Abstract
BACKGROUND In livestock breeding, oocyte cryopreservation is crucial for preserving and transferring superior genetic traits. This study was conducted to examine the additional effect of melatonin to maturation and vitrification media on the in vitro developmental capacity, mitochondrial distribution, and intensity of buffalo oocytes. The study involved obtaining ovaries from a slaughterhouse and conducting two phases. In the first phase, high-quality oocytes were incubated in a maturation medium with or without 10-9M melatonin for 22 h (at 38.5°C in 5% CO2). Matured oocytes were fertilized in vitro and cultured in SOF media for seven days. In the second phase, vitrified in vitro matured oocytes were stored in vitrified media (basic media (BM) containing a combination of cryoprotectants (20% Ethyl Glycol and 20% Dimethyl sulfoxide), with or without melatonin, and then stored in liquid nitrogen. Normal vitrified/thawed oocytes were fertilized in vitro and cultured as described. Finally, the matured oocytes from the fresh and vitrified/thawed groups, both with and without melatonin, were stained using DAPI and Mitotracker red to detect their viability (nuclear maturation), mitochondrial intensity, and distribution using a confocal microscope. The study found that adding 10-9M melatonin to the maturation media significantly increased maturation (85.47%), fertilization rate (84.21%)cleavage (89.58%), and transferable embryo (48.83%) rates compared to the group without melatonin (69.85%,79.88%, 75.55%, and 37.25% respectively). Besides that, the addition of melatonin to the vitrification media improved the recovery rate of normal oocytes (83.75%), as well as the cleavage (61.80%) and transferable embryo (27.00%) rates when compared to the vitrified TCM group (67.46%, 51.40%, and 17.00%, respectively). The diffuse mitochondrial distribution was higher in fresh with melatonin (TCM + Mel) (80%) and vitrified with melatonin (VS2 + Mel groups) (76.70%), Furthermore, within the same group, while the mitochondrial intensity was higher in the TCM + Mel group (1698.60) than other group. In conclusion, Melatonin supplementation improves the developmental competence and mitochondrial distribution in buffalo oocytes in both cases(in vitro maturation and vitrification).

Abstract
The efficiency of animal artificial breeding in vitro is still low. Oxidative damage is an important obstacle for in vitro artificial breeding of animals. Melatonin can reduce the degree of oxidative damage to both gametes and embryos caused by the external environment. However, there is still some controversy concerning the effect of melatonin on frozen semen, especially in the processes of freezing semen, IVM, IVF and IVC. Here, the effects of melatonin on the whole processes of sperm cryopreservation, oocyte maturation, and embryonic development were studied. The results demonstrated that melatonin at 10-3 M concentration significantly improved progressive sperm viability, plasma membrane integrity, mitochondrial membrane integrity, and acrosome integrity; however, there were also individual differences between bulls, depending on the age of different individuals. The 10-3 M melatonin treatment reduced the reactive oxygen species (ROS) level by nearly 50% in sperm during IVF. Meanwhile, during IVM, the addition of 10-7 M melatonin significantly increased the maturation rate of oocytes and reduced the ROS levels by 58.8%. In addition, 10-7 M melatonin improved the total cell numbers of the IVF blastocysts. Notably, treatment of IVF embryos with melatonin significantly reduced the levels of ROS and influenced the expression levels of key regulatory genes associated with embryo genome activation. This study is of significance for understanding the function of melatonin in animal artificial breeding.

Effect of melatonin supplementation during IVM of dromedary camel oocytes (Camelus dromedarius) on their maturation, fertilization, and developmental rates in vitro. Theriogenology 2021; 172:187-192.

Abstract
The positive impact of melatonin on in vitro embryo production (IVEP) has been reported in many domestic species; however, no studies have been carried out in camelids. We aimed to evaluate the effects of melatonin supplementation in maturation media on in vitro maturation, fertilization, and preimplantation embryo development of dromedary camel oocytes (experiment 1). We also evaluated the concentrations of total antioxidant capacity (TAC), and malondialdehyde (MDA) in the IVM spent medium in relation to melatonin supplementation. Cumulus oocyte complexes (COCs) were cultured in in vitro maturation media (IVM) supplemented with either 0.0, 25.0, 50.0 or 75.0 μM of melatonin for 30 h. Matured oocytes were then fertilized in vitro with epididymal camel spermatozoa. Following IVF, the resulting embryos were cultured in vitro for seven days. The percentage of maturation, fertilization, cleavage, and embryo developmental rates (morula and blastocyst) was recorded (experiment 1). TAC and MDA levels in the IVM spent maturation media were also evaluated at 30 h post-IVM (experiment 2). The results showed that supplementation of IVM media with 25 μM melatonin significantly improved oocyte nuclear maturation, fertilization (18 h post-insemination; pi), cleavage (day 3 pi), morula (day 5 pi) and blastocyst (day 7 pi) rates as compared with the controls and other melatonin-supplemented groups. Furthermore, the TAC in the IVM spent media was significantly increased (P < 0.05) in 25 μM melatonin supplemented groups than those supplemented with 0.0, 50.0, 75.0 μM melatonin. However, the concentration of MDA was significantly lower (P < 0.05) in IVM media supplemented with 25.0 μM of melatonin when compared with the control and other treatment groups. In conclusion, supplementation of IVM medium with 25 μM of melatonin could enhance the in vitro developmental capacity of dromedary camel oocytes.

Abstract
Seasonal breeding in buffalo is influenced by exogenous (photoperiod, climate, nutrition, management) and endogenous (hormones, genotype) factors. Buffalo are negatively photoperiodic and show a natural increase in fertility during decreasing day length. The hormone melatonin is produced by the pineal gland and has a fundamental role in photoperiodic time measurement within the brain. This drives annual cycles of gonadotropin secretion and gonadal function in buffaloes. Some melatonin is released into the systemic circulation and, together with peripherally produced melatonin, acts at somatic tissues. In the ovaries and testes of buffalo, melatonin acts as an antioxidant and scavenges oxygen free radicals to reduce both oxidative stress and apoptosis. This has beneficial effects on gametogenesis and steroidogenesis. Female buffalo treated with melatonin show an improved response to estrus synchronization protocols in out-of-season breeding. Melatonin acts through melatonin receptors MT1 and MT2 and the gene for MT1 (MTNR1A) is polymorphic in buffaloes. Single nucleotide polymorphisms (SNPs) in gene MTNR1A have been associated with fertility in female buffalo. The knowledge and tools are available to lift the reproductive performance of buffalo. This is highly important as the global demand for nutritious buffalo food products has undergone a sharp rise, and continues to grow. Buffalo can make an important contribution to affordable, nutritious animal protein. This will help address global nutritional security.

Abstract
ABSTRACT We aimed to assess the effects of melatonin in the in vitro production of bovine embryos. Our experiment was conducted at the Laboratório de Reprodução Animal of the Universidade Estadual do Maranhão. The cumulus-oocyte complexes (COCs) were distributed among treatments at concentrations of 0, 10-1, 10-3 and 10-5 µMol/L melatonin. Our experiment was further divided into two: the first was to assess the effect of different concentrations of melatonin (treatments) on the maturation rate of COCs, and the second was to assess the effects of melatonin treatments on the in vitro production of bovine embryos. The results from the first experiment demonstrated no significant difference between the in vitro maturation rate of the cultivated COCs in treatments with melatonin. In the second experiment, however, melatonin treatments yielded statistically higher cleavage, morula and blastocyst rates in the 10-5 µM group (52.9%, 52.9%, and 35.3%, respectively), and lower rates in the 10-1 µM group (19.5%, 19.5% and 7.8%, respectively), compared to the others. The control group (no melatonin) and the 10-3 µM group showed similar results. We concluded that supplementation of melatonin in the in vitro maturation medium resulted in no improvement in the oocyte maturation rate, but in the in vitro production of embryos at different concentrations, the 10-5 µM group displayed better results, but with no improvement in the variables (P < 0.05).

Abstract
This study aimed to investigate the effect of melatonin supplementation at different levels in culture medium on embryo development in rabbits. Embryos of 2-4 cells, 8-16 cells and morula stages were recovered from nulliparous Red Baladi rabbit does by laparotomy technique 24, 48 and 72 h post-insemination, respectively. Normal embryos from each stage were cultured to hatched blastocyst stages in either control culture medium (TCM-199 + 20% fetal bovine serum) or control supplemented with melatonin at 10(-3) M, 10(-6) M or 10(-9) M. No effect of melatonin was found on development of embryos recovered at 24 h post-insemination. The high level of melatonin at 10(-3) M adversely affected the in vitro development rates of embryos recovered at 48 h post-insemination (52 versus 86, 87 and 80% blastocyst rate; 28 versus 66, 78 and 59% hatchability rate for 10(-3) M versus 10(-9) M, 10(-6) M and control, respectively, P< 0.05). At the morula stage, melatonin at 10-3 M significantly increased the in vitro development of embryos (92% for 10(-3) M versus 76% for control, P < 0.05), while the hatchability rate of these embryos was not improved by melatonin (16-30% versus 52% for melatonin groups versus control, P < 0.05). Results show that a moderate level of melatonin (10(-6) M) may improve the development and hatchability rates of preimplantation rabbit embryos. The addition of melatonin at a 10-3 M concentration enhances the development of rabbit morulae but may negatively affect the development of earlier embryos. More studies are needed to optimize the use of melatonin in in vitro embryo culture in rabbits.
