Abstract
In contrast to the livestock industry, sperm cryopreservation has not yet been successfully established in the poultry industry. This is because poultry sperm cells have a unique shape and membrane fluidity, differing from those of livestock sperm. The objective of this review is to discuss the cellular and molecular characteristics of rooster spermatozoa as a cause for their generally low freezability. Furthermore, here, we discuss novel developments in the field of semen extenders, cryoprotectants, and freezing processes, all with the purpose of increasing the potential of rooster sperm cryopreservation. Currently, it is very important to improve cryopreservation of rooster sperm on a global scale for the protection of gene resources due to the incidence of epidemics such as avian influenza.

Abstract
Semen cryopreservation is a key biotechnological strategy used to preserve and protect genetic resources, which are subject to increasingly serious reductions in some species, and to protect animal biodiversity. Assisted reproductive techniques, however, are still not utilized to the same extent in avian species to the extent that occurs in mammals. The reasons for this situation are described in this review. The content of this paper is focused on current poultry preservation systems, published since 2010, and new strategies that are very promising for preserving avian genetic resources. Two major types of storage technologies which are utilized for avian sperm preservation, liquid storage and cryopreservation, are emphasized. The issues on which there is a focus includes supplementation of avian extenders with various compounds prior to the preservation period, use of cryoprotectants and fertility results when there were in vitro sperm evaluations. Results from recent studies indicate there are opportunities to improve the quality of bird semen after preservation. It is obvious that cryo-diluent composition may be the most important factor for development of efficacious cryopreservation methods for avian semen.

Abstract
A widely used approach to preserving genetic diversity in birds involves the cryopreservation of semen. In this process, cells are subjected to physical and chemical stresses, but not all cell species respond equally. Many studies have been published on the freezing-thawing of sperm cells from a wide variety of domestic and wild species, on issues ranging from the sperm quality to different protocols, fertilisation success rates, etc. Nevertheless, very little information is available on the common pheasant. To fill this gap, the aim of this study was to describe the pheasant semen collection method, evaluate some qualitative parameters of sperm from males fed an antioxidant-enriched diet, and to test the in vivo fertilising capacity of the cryo-preserved semen. The freezing protocol employed involved pellets thawed by the hotplate method. Dimethylacetamide was used as a cryoprotectant at a final concentration of 6%. A total of six AIs were performed at 3-4-day intervals on a total of 40 females with doses of 35 × 106 of normal live thawed sperm. Males receiving the enriched diet produce more abundant and concentrated ejaculates. Freeze-thawed sperm lost 85% of their initial mobility, and diet influenced neither sperm mobility nor viability. The enriched diet did improve the number of normal freeze-thawed cells and was associated with a lower sperm fracture incidence. Regardless of the dietary group, frozen-thawed sperm resulted in a fertility rate of 30%, with 8-9 chicks hatching for every 100 eggs incubated.

Abstract
The sperm of each avian species and breed have unique characteristics that render them more or less susceptible to the freezing-thawing process; therefore, a suitable cryopreservation protocol that is specific for the sperm of each type of bird is needed. In this context, little information about the common pheasant's sperm is available. Therefore, the aim of this study was to test different parameters at each step of the process of freezing into pellets and thawing to detect the least deleterious parameter settings. Sixteen different protocols were tested by studying two levels in each of the four steps (dilution, equilibration at 5 °C, final dimethylacetamide concentration, and dimethylacetamide equilibration time) comprising the freezing process. The pheasant sperm exhibited a high susceptibility to the damage caused by freezing into pellets; however, the survival of the sperm reached 29%, and the greatest recovered mobility was 22%. The mobility of the sperm was affected by the dilution and the dimethylacetamide concentration, and the viability of the sperm was affected by the equilibration at 5 °C and the dimethylacetamide equilibration. The protocols that caused the least damage to the pheasant sperm were found to be those with higher dilution rates, 10 min of equilibration at 5 °C, and 6% dimethylacetamide equilibrated for 1 or 5 min. In the present study, we individualise some applicable parameters for certain critical steps of the freezing-thawing process; however, further investigations are needed in order to improve upon and complete a suitable protocol for the cryopreservation and thawing of pheasant sperm.

Abstract
Harris hawks (Parabuteo unicinctus) are the raptors with more anthropogenic use, which makes it necessary to improve their reproduction either natural or assisted for sustainable use even though they are not endangered. The aim of this study was to determine fresh and thawed P. unicinctus sperm capacitation and acrosome reaction parameters as indicators of sperm viability in ejaculates of birds with injuries. A total of 30 ejaculates were analyzed as fresh and thawed samples. Basic sperm evaluations as well as in vitro acrosomal reaction capability through the presence and distribution of Ca2+ and N-acetylglucosamine and sialic acid using chlortetracycline and agglutinin-fluorescein isothiocyanate Triticum vulgaris were performed, respectively. Tagged samples were observed using epifluorescence microscopy. The results indicated 30.00% decrease in sperm viability following freeze-thaw, while rate of capacitated sperms (10.00%) and the percentage of sperm with acrosomal reaction (40.00%) were increased. The results of the experiment demonstrated that the post-thaw viability of the obtained sperm may be an alternative for use in artificial insemination.

Abstract
Cryopreservation protocols for semen exist for bird species used in animal production, fancy and hobby species, and wild bird species. Freezing of bird oocytes or embryos is not possible. Cryopreservation of avian semen is used for preserving (genetic diversity of) endangered species or breeds. Freezing semen can also be used in the breeding industry for maintaining breeding lines, as a cost-effective alternative to holding live birds. Success and efficiency of cryopreservation of bird semen differs among species and breeds or selection lines. This chapter describes important variables of methods for collecting, diluting, cold storage, and freezing and thawing of bird semen, notably the medium composition, cryoprotectant used and its concentration, cooling rate, freezing method, and warming method. Media and methods are described for freezing semen using either glycerol or DMA as cryoprotectant, which both are known in chicken and a number of other bird species to render adequate post-thaw fertility rates.

Abstract
The germplasm is a resource and tool for the conservation of genetic diversity in animals, including birds. Securing germplasm is limited in most bird species due to difficulties in semen collection and germ cell isolation, lack of germ cell-specific markers, and in vitro culture systems. Here, we report the production of germline chimeric quails by transplant of cryopreserved testicular cells (TCs) into the developing embryo. The testicular germ cell properties were maintained after freeze-thaw, with no significant reduction in cell viability irrespective of storage length. Cryopreserved TCs were transferred into Hamburger Hamilton (HH) stage 14-17 quail embryos, and were demonstrated to migrate into the embryonic gonads with similar efficiency to freshly isolated TCs. Twenty of 81 recipient embryos yielded hatchlings from cryopreserved TCs and the germline transmission efficiency was similar to that of freshly isolated cells. In conclusion, cryopreserved adult quail TCs are capable of (de)differentiation into functional gametes in recipient quail gonads and can generate donor TCs-derived progenies. This system is feasible for the isolation of sufficient germplasm resources from various bird species for conservation purposes.

Abstract
This review presents the current progress in and approaches to in vitro conservation of reproductive
cells of animals, including birds, such as cryopreservation and freeze-drying, as well as epigenetic conditions for
restoring
viable spermatozoa and female gametes after conservation. Cryopreservation is an effective way to preserve
reproductive cells of various species of animals and birds. In vitro gene pool conservation is aimed primarily
to the restoration of extinct breeds and populations and to the support of genetic diversity in populations prone
to genetic drift. It is the combination of ex situ in vivo and ex situ in vitro methods that can form the basic principles
of the strategy of animal genetic diversity preservation. Also, use of cryopreserved semen allows faster breeding
in industrial poultry farming. Despite numerous advances in semen cryobiology, new methods that can more efficiently
restore semen fertility after cryopreservation are being sought. The mechanisms underlying the effect of
cryopreservation on the semen parameters of cocks are insufficiently understood. The review reflects the results
of recent research in the field of cryopreservation of female and male germ cells, embryonic cells, the search for
new ways in the field of genetic diversity in vitro (the development of new cryoprotective media and new conservation
technologies: freeze-drying). Molecular aspects of cryopreservation and the mechanisms of cryopreservation
influence on the epigenetic state of cells are highlighted. Data on the results of studies in the field of male
reproductive cell lyophilization are presented. The freeze-drying of reproductive cells, as a technology for cheaper
access to the genetic material of wild and domestic animals, compared to cryopreservation, attracts the attention
of scientists in Japan, Israel, Egypt, Spain, and France. There is growing interest in the use of lyophilized semen
in genetic engineering technologies. Methods of freeze-drying are developed taking into account the species of
birds. Organizational and legal ways of solving the problems of in vitro conservation of genetic resources of farm
animals, including birds, are proposed.

Abstract
Simple Summary The most adopted biotechnology for the conservation of genetic resources in avian species is semen cryopreservation. Therefore, the identification of a reference cryopreservation procedure represents a key point for ensuring the long-term conservation of genetic diversity in birds, through the implementation of a semen cryobank. In this study, our goal was to discover an effective freezing protocol for Meleagris gallopavo in order to realize the first Italian semen cryobank of autochthonous chicken and turkey breeds within our project (TuBAvI). For this purpose, we investigated the effects of three non-permeant cryoprotectants (sucrose, trehalose, and Ficoll) and two dilution rates (1:2 and 1:4) on the in vitro cryosurvivability of turkey spermatozoa. After thawing, the best semen quality was found in semen frozen in the presence of Ficoll and diluted at a final rate of 1:4. This paper provides encouraging results, however further studies are programmed to standardize the semen cryopreservation protocol. Abstract The present study aimed to find an effective cryopreservation protocol for turkey semen through the combined use of dimethylsulfoxide (DMSO) and three non-permeant cryoprotectants (NP-CPAs), sucrose, trehalose, and Ficoll 70. In addition, the action of two dilution rates (1:2 and 1:4) were also investigated. Semen was processed according to two final dilution rates and the following treatments: Tselutin extender (TE)/DMSO (control), TE/DMSO + sucrose or trehalose 50, 100, 200, or 400 mM, and TE/DMSO + Ficoll 0.5, 0.75, 1, or 1.5 mM. In total 26 different combinations treatments were achieved. The diluted semen was filled up into straws and frozen on liquid nitrogen vapor. The post-thawing sperm quality was assessed by analyzing motility, membrane integrity, osmotic resistance, and DNA integrity. The results obtained revealed a significant effect of NP-CPA concentration on total and progressive motility, on most of the kinetic parameters, on membrane integrity and DNA integrity, while the post-thaw quality was less affected by dilution rate. The highest post-thaw quality for all sperm quality parameters assessed except curvilinear velocity (VCL) and DNA integrity were found in semen frozen with 1 mM Ficoll/1:4 (p < 0.05). Our findings provide an important contribution for the identification of a reference procedure for turkey semen cryopreservation, in order to create the first national avian semen cryobank.

Abstract
Chicken semen conservation is an important tool for programs of genetic diversity management and of endangered breeds’ conservation. However, the method still needs to be improved in order to be applied in a wide variety of environments and breeds. Our objective was to compare the effects of 2 external cryoprotectants saccharides (sucrose and raffinose) on the sperm freezability of a Thai local breed, Pradu Hang Dum, in which semen was frozen with a simple freezing method using nitrogen vapors and dimethyl formamide (DMF). Thirty-six males were selected on their motility vigor score for the experiments. In a first experiment, a large range of sucrose and raffinose doses were tested. Semen quality was evaluated after incubation at 5°C or after cryopreservation in straws in the saline Blumberger Hahnen Sperma Verdünner diluent + DMF (6% v/v) with or without sucrose/raffinose. The best targeted doses of sucrose and raffinose were then kept for experiment 2 that was focused on cryopreserved semen. In this experiment, semen quality was measured on frozen-thawed sperm: different objective motility data evaluated by computer-assisted sperm analysis (CASA), membrane integrity, acrosome integrity, mitochondria function evaluated using flow cytometry, lipid peroxide production assessed by the thiobarbituric acid test. Fertility obtained with frozen-thawed semen supplemented or not with sucrose or raffinose was also evaluated after artificial insemination of laying hens. The presence of sucrose at the osmotically inactive dose 1 mmol significantly increased the vigor motility, membrane integrity, acrosome integrity, and mitochondrial functions of frozen-thawed sperm (P < 0.05), and showed the highest levels of fertility after sperm cryopreservation (91% vs. control 86%, P < 0.001). Raffinose showed negative effects on in vitro semen quality from 1 to 100 mmol. Fertility was also negatively (P < 0.001) affected by raffinose (fertility rate 66 to 70%). We thus showed in the present study the high success of a simple chicken sperm cryopreservation method with an external cryoprotectant easily available and cheap, the sucrose, used at an osmotically inactive low concentration.

Abstract
The aim of the study was to find a practical and inexpensive method for freezing goose semen for use in routine inseminations under farm conditions. Two basic freezing protocols [(1) dynamic, programmable freezing and (2) static, nitrogen vapour method] were evaluated with varying concentrations of dimethylformamide (DMF) plus additional osmoprotectants such as betaine, trehalose, and sucrose, using cryovials as containers. Altogether eight different treatments were compared. sperm viability before freezing and after thawing was examined by in vitro tests and, in the case of the simplest effective method, also by in vivo fertility test. There were no significant differences in sperm survival either in the dynamic (48-50%) or in the static protocol (43-46%), except for the treatment where the lowest DMF concentration was used without any osmoprotectant in the dynamic protocol (42.6%). The addition of osmoprotectants did not improve thawed sperm viability in any case. Fertility with frozen/thawed sperm using the simplest method was 58.5%, while that obtained with fresh, diluted semen was 66.9%. The study proved that the simple freezing of gander semen in nitrogen vapour with 9% DMF in cryovials could produce acceptable fertility. The newly elaborated method can be successfully used for routine inseminations by small- and large-scale goose breeders.

Abstract
Egg yolk is a good external cryoprotectant of mammalian sperm and some wild bird's sperm, but, at least in domestic breeds of chicken (Gallus gallus domesticus), it may inhibit eventual fertilization of ova when high concentrations are used. We hypothesized that egg yolk can protect the sperm from cryo-induced damages providing adequate fertilization in one phylogenetic wild ancestor of current chicken breeds: the Indian red jungle fowl (Gallus gallus murghi). To test the hypothesis, the present study was designed to evaluate different concentrations of egg yolk in extender in comparison with glycerol. Semen collected from Indian red jungle fowl cocks (n = 8) was cryopreserved using different egg yolk concentrations (10%, 15%, 20% and 25%) or 20% glycerol (control group) following routine protocol of cryopreservation. During cryopreservation, sperm motility (67.5 ± 2.5%), plasma membrane integrity (66.3 ± 2.4%), viability (58.8 ± 1.3%) and acrosomal integrity (60.0.8 ± 2.0%) were recorded highest in an extender with 15% egg yolk compared to other experimental extenders and control at post-dilution, cooling, equilibration and thawing. The no. of fertilized eggs (26.6 ± 0.7, 21.6 ± 1.2), percent fertility (55.9 ± 4.4, 46.5 ± 2.2), no. of hatched chicks (23.6 ± 1.0, 17.2 ± 1.0), percent hatch (49.5 ± 3.2, 37.1 ± 2.5%) and hatchability of the fertile eggs (89.4 ± 2.2, 79.7 ± 3.7) were recorded higher (P < 0.05) with semen cryopreserved with 15% egg yolk compared to control (20% glycerol). It is concluded that 15% egg yolk can be used in cryopreservation protocol of Indian red jungle fowl sperm.

Abstract
The impacts of zinc oxide nanoparticles on embryonic development following oocyte stage exposure are unknown and the underlying mechanisms are sparsely understood. In the current investigation, intact nanoparticles were detected in ovarian tissue in vivo and cultured cells in vitro under zinc oxide nanoparticles treatment. Zinc oxide nanoparticles exposure during the oocyte stage inhibited embryonic development. Notably, in vitro culture data closely matched in vivo embryonic data, in that the impairments caused by Zinc oxide nanoparticles treatment passed through cell generations; and both gamma-H2AX and NF-kappaB pathways were involved in zinc oxide nanoparticles caused embryo-toxicity. Copper oxide and silicon dioxide nanoparticles have been used to confirm that particles are important for the toxicity of zinc oxide nanoparticles. The toxic effects of zinc oxide nanoparticles emanate from both intact nanoparticles and Zn2+. Our investigation along with others suggests that zinc oxide nanoparticles are toxic to the female reproductive system [ovaries (oocytes)] and subsequently embryo-toxic and that precaution should be taken regarding human exposure to their everyday use.

Abstract
Melopsittacus undulatus is largely used as a potential model for assisted reproduction in other endangered parrot species. Semen was collected from nineteen healthy adult males, by massage technique, during the breeding season. After preliminary evaluations through CASA analysis, eight birds were selected as semen donors and five ejaculates of each bird were utilized to evaluate the effect of 10% ethylene glycol (EG) addition, in two times, during 40min of equilibration time at 4°C, and to compare two programmable freezing curves (a rapid and a slow temperature descent rate) and freezing on nitrogen vapors. Diluted semen (modified TALP, pH 8.4) was divided into two aliquots, the first for freezing individual samples, the second to be mixed in a semen pool from the eight birds. Potential inseminating doses of 10μl, containing 1×106 spermatozoa, were frozen. The effect of EG addition on semen motility and kinetic parameters was analyzed and the three freezing methods were compared. EG addition caused a significant decline of semen motility in individual samples, not in semen pools. The three freezing curves resulted in significant differences in thawed-semen parameters, with nitrogen vapors showing the worst results, while the higher total and progressive motility values were obtained with the 'fast' protocol. Thawed-semen pools motility and kinetic parameters appeared lower than those of the individual ejaculates. The differences found between single ejaculates and semen pools emphasize the importance of performing artificial insemination tests in order to assess the in vivo performance of single ejaculates in the parrot species.

Abstract
Low survival of cryopreserved sperm impedes the application of cryopreservation technique in spermcasting oyster species. This study developed a simple method of liquid nitrogen vapor freezing to improve post-thaw sperm survival in the spermcasting oyster Ostrea angasi. The results indicate that the permeable cryoprotectants, dimethyl sulfoxide (DMSO), ethylene glycol (EG) and propylene glycol (PG) were non-toxic to sperm up to 20% concentration and 90 min exposure whereas methanol at 10% or higher was toxic to sperm for any exposure over 30 min. Among the treatments with permeable cryoprotectants, 15% EG produced the highest post-thaw sperm motility. Sperm motility was further improved by the addition of non-permeable cryoprotectants (trehalose and glucose), with 15% EG + 0.2 M trehalose resulting in the highest post-thaw sperm motility among all the combinations evaluated. The durations of 20, 30 and 60 min equilibrations produced a higher post-thaw sperm motility and plasma membrane integrity (PMI) than 10 min. Higher post-thaw motility and PMI were achieved by freezing sperm at the 8 cm height from the liquid nitrogen surface than at the 2, 4, 6, 10 or 12 cm height. Holding sperm for 10 min in liquid nitrogen vapor produced higher post-thaw motility and PMI than for 2, 5 or 20 min. The cryopreservation protocol developed in this study improved both post-thaw motility and PMI of O. angasi sperm at least 15% higher than those cryopreserved using programmable freezing method. Liquid nitrogen vapor freezing might have greater applicability in improving post-thaw sperm quality of spermcasting oyster species.

Abstract
Primordial germ cells (PGCs) generate new individuals through differentiation, maturation and fertilization. This means that the manipulation of PGCs is directly linked to the manipulation of individuals, making PGCs attractive target cells in the animal biotechnology field. A unique biological property of avian PGCs is that they circulate temporarily in the vasculature during early development, and this allows us to access and manipulate avian germ lines. Following the development of a technique for transplantation, PGCs have become central to avian biotechnology, in contrast to the use of embryo manipulation and subsequent transfer to foster mothers, as in mammalian biotechnology. Today, avian PGC transplantation combined with recent advanced manipulation techniques, including cell purification, cryopreservation, depletion, and long-term culture in vitro, have enabled the establishment of genetically modified poultry lines and ex-situ conservation of poultry genetic resources. This chapter introduces the principles, history, and procedures of producing avian germline chimeras by transplantation of PGCs, and the current status of avian germline modification as well as germplasm cryopreservation. Other fundamental avian reproductive technologies are described, including artificial insemination and embryo culture, and perspectives of industrial applications in agriculture and pharmacy are considered, including poultry productivity improvement, egg modification, disease resistance impairment and poultry gene "pharming" as well as gene banking.

Abstract
A continuous decline in the number and range of capercaillie (Tetrao urogallus L.) in many European countries can be observed, mostly due to habitat destruction by human activity, unecological forestry management, and increased density of natural predators. Ex situ in vitro gene banks provide a unique opportunity to preserve the genetic material for future generations. Simple and effective cryopreservation methods for capercaillie semen are discussed. Semen was collected from seven males kept in the Capercaillie Breeding Centre at Forestry Wisła in Poland. Within five minutes after collection, ejaculates were diluted with EK diluent, then divided into two parts, and subjected to two freezing procedures: in pellets and in straws. In fresh semen, ejaculate clearness, viscosity, color and volume, as well as sperm concentration, motility and morphology, were evaluated, while in frozen-thawed semen only motility and morphology of sperm were determined. Fertilizing ability of thawed semen was examined for samples frozen in straws. Significant (P<0.05) differences between individual males were found in relation to the majority of fresh semen traits: ejaculate volume averaged 102.1 µL (varying from 49.0 to 205.0); average sperm concentration was 632.5 x106 mL-1 (178.8–1257.1); percentage of live normal cells varied from 39.2 to 70.3% (58.7% on an average); percentage of motile cells ranged from 76.0 to 85.7%) and motility parameters were male dependent, as well. Both cryopreservation methods had a negative effect on morphology and motility of frozen-thawed semen; however, the straw method yielded 60.7% and the pellet method 42.5% of live cells in total in thawed semen (P<0.05), while the number of live normal (intact) cells was similar (22.4 and 22.2%, respectively). Egg fertility varied between 77.8 and 91.7% (average 84.4%). Both freezing procedures seem to be effective in obtaining acceptable viability and high fertilizing potency of thawed sperm and can be used to create a gene bank of capercaillie semen.

Abstract
France is the only country that practices pedigree selection of guinea fowl for meat production. The increasing risk of line extinction for sanitary or breeding failure reasons makes clear the need for an efficient method of reproductive cell cryopreservation in this species. However, an efficient method of guinea fowl sperm freezing in secured packaging is still lacking. The aim of the present study was to develop such a method. Based on results previously obtained in chickens, different cryoprotectants and freezing/thawing processes were tested and then adapted to guinea fowl. Semen quality was measured by semen viability evaluation and then by fertility measured after intravaginal artificial insemination. The best results (70% fertility with frozen-thawed sperm) were obtained by the use of the permeant cryoprotectant agents dimethyl formamide combined with a freezing rate of 30°C/min. The initial insemination frequency also affected the fertility results: 2 consecutive days of inseminations were needed in the first week to ensure enough filling of the utero-vaginal glands of the guinea fowl hen and thus to get successive fertile eggs. Thereafter, a 2-wk insemination frequency was sufficient. This new method, combining biophysical (cryoprotectant agents, freeze/thaw rate) and zootechnical (artificial insemination frequency) features, is the first cryopreservation method successfully developed in secured packaging for guinea fowl sperm. This method is now available for the practice of gene bank conservation and male reproductive management.
