Abstract
The aim of the current study was to determine the effects of dietary supplementation of safflower seed (SS) on the growth performance and hematological parameters of broiler birds along with the physicochemical, textural and sensory attributes of chicken meat. A total of 200 male chickens (7-days-old) were distributed into 5 groups (40 chickens in each) with 5 replicates of 8 chicks in a 42-day experiment. Each group was allocated to one of 5 dietary treatments, i.e., 0, 2.5, 5, 7.5, and 10% SS. The experimental diets were formulated for starter (7 to 21 days) and finisher (22 to 42 days) phases. Inclusion of SS in the diet improved growth performances in treatment groups between 7 and 42 days. The highest and lowest body weights were observed at the 5% SS and 0% SS levels, respectively. The physicochemical attributes of breast and thigh meat were found (P > 0.05) except for crude fat. The crude fat was significantly (P < 0.05) increased with increasing levels of SS in the diet. The inclusion of SS in the diet did not negatively impact the textural properties, i.e., hardness, cohesiveness, springiness, gumminess, chewiness, and shear force of breast and thigh meat. There was no significant difference in the sensory parameters of cooked chicken meat with increasing levels of SS in the diet. The results demonstrated a significant (P < 0.01) improvement in hematological parameters in the blood samples of broiler chickens fed diet supplemented with various levels of SS for five weeks. These findings suggest that, SS may be used as an oil seed for broiler chicken feed.

Effect of the dietary inclusion of Camelina sativa cake into quail diet on live performance, carcass traits and meat quality. Poult Sci 2023; 102:102650. [PMID: 37031586 PMCID: PMC10120358 DOI: 10.1016/j.psj.2023.102650] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 03/06/2023] [Accepted: 03/06/2023] [Indexed: 03/18/2023] Open
Abstract
The present research studied the effect of the dietary inclusion of 3 different camelina (Camelina sativa (L.) Crantz) cakes on the live performance, slaughter traits, and breast meat quality of broiler quails (Coturnix japonica). With this purpose, a total of 480 fifteen-day-old broiler quails of both sexes were allocated to 48 cages (12 replicates/treatment, 10 quails/replicate) and received 4 dietary treatments: a control diet (Control), and 3 diets containing 15% of 1 commercial cultivar (Calena), and 2 improved lines (Pearl: low linoleic acid; Alan: low glucosinolates). During the experiment, individual live weight (LW) and cage feed intake were recorded to calculate body weight gain (BWG) and feed conversion ratio (FCR). At 35 d of age, quails were slaughtered, and carcasses were weighed and dissected to compute yields. On breast (pectoralis major muscle) the measurements and analyses considered ultimate pH, L*a*b* color values, proximate composition, oxidative status, cooking loss and WBSF toughness. Broiler quails receiving diets with camelina cakes exhibited mortality and health status similar to the control. However, growth performance was impaired in camelina-fed groups, especially for Calena (P < 0.05). Overall LW and BWG were slightly lower, whereas feed intake was slightly higher in camelina-fed groups compared to Control (P > 0.05). Therefore, higher FCR was recorded for camelina-fed groups compared to Control (P = 0.0004). Moreover, breast meat from Calena treatment displayed higher water (P = 0.0170), and lower lipid (P = 0.0051) contents compared to those of the Control group, while protein and ash content remained unaffected. Heme-iron content and oxidative status of breast meat were not influenced by the dietary incorporation of camelina (P > 0.05). The research outcomes indicated that camelina cakes can be used as an alternative feed ingredient for broiler quails' diets, without compromising carcass yields and meat quality. However, as 15% dietary incorporation worsened live performance, the ideal camelina cake inclusion level should be thoroughly investigated as well as a parallel research effort into further reducing glucosinolates content of camelina.

Abstract
In this study, we included 15% doses of infrared-irradiated camelina, flax, and sunflower seeds in the diets of broiler chickens (grower and finisher) and focused on assessing the effects on the production traits, selected slaughter analysis parameters, nutrients, and minerals in breast and drumstick meat and some organs, i.e., liver, proventriculus, and heart. In total, 200 one-day-old broiler chickens were assigned randomly to four treatments with five replicate cages of 10 broiler chickens per cage (five females and five males). The experiment lasted 6 weeks. In the group of broiler chickens in which diets were supplemented with micronised camelina and flax seeds, there was an increase in (p < 0.05) breast, thigh, and drumstick weight and a decrease (p < 0.05) in the abdominal fat of the carcasses. The oilseed treatments reduced the ether extract content and the calorific value in the breast and drumstick muscles and organs. The flax seeds contributed to an increase in the contents of Ca (breast muscle and liver), Cu (breast muscle and proventriculus), and Fe (drumstick muscle and heart). Likewise, some blood parameters were influenced by supplementation with infrared-irradiated camelina and flax seeds, for example, there was a decrease in the haemoglobin level and the mean corpuscular haemoglobin concentration (p < 0.05). The oilseed treatments also modified the contents of Fe and Ca in the blood plasma of broiler chickens (p < 0.05). It may be concluded that infrared-irradiated camelina, flax, and sunflower seeds can be regarded as good diet components exerting positive effects on the dietary value of poultry meat and organs used in dietetics.

Use of Camelina sativa and By-Products in Diets for Dairy Cows: A Review. Animals (Basel) 2022; 12:ani12091082.

Abstract
Camelina sativa, belonging to the Brassicaceae family, has been grown since 4000 B.C. as an oilseed crop that is more drought- and cold-resistant. Increased demand for its oil, meal, and other derivatives has increased researchers’ interest in this crop. Its anti-nutritional factors can be reduced by solvent, enzyme and heat treatments, and genetic engineering. Inclusion of camelina by-products increases branched-chain volatile fatty acids, decreases neutral detergent fiber digestibility, has no effect on acid detergent fiber digestibility, and lowers acetate levels in dairy cows. Feeding camelina meal reduces ruminal methane, an environmental benefit of using camelina by-products in ruminant diets. The addition of camelina to dairy cow diets decreases ruminal cellulolytic bacteria and bio-hydrogenation. This reduced bio-hydrogenation results in an increase in desirable fatty acids and a decrease in saturated fatty acids in milk obtained from cows fed diets with camelina seeds or its by-products. Studies suggest that by-products of C. sativa can be used safely in dairy cows at appropriate inclusion levels. However, suppression in fat milk percentage and an increase in trans fatty acid isomers should be considered when increasing the inclusion rate of camelina by-products, due to health concerns.

Abstract
Camelina has been used from ancient times, but recently has re-emerged as a valuable plant with the potential for successful replacement of conventional oilseed crops. The utilisation of camelina and its by-products in animal feed is a matter of scientific study due to their excellent nutritional potential. The present study aimed to investigate the nutritive value of two Serbian camelina seed genotypes (NS Zlatka and NS Slatka) as a potential alternative to commonly used oilseed crops in animal feeding. For that purpose proximate composition, fatty acid profile, amino acid profile and tocopherols were analysed. The study also included the investigation of the content of anti-nutritive compounds that can adversely affect the nutritional value of feed. The results showed that camelina seeds had a high amount of proteins (around 28%), amino acids and gtocopherols. Camelina genotypes were characterized by unique fatty acids composition, with its oil consisting of approximately 57% polyunsaturated fatty acids, of which the highest proportions were a-linolenic acid (~37%) and linoleic acid (~17%). An optimal ratio of n-6 and n-3 fatty acids (0.5) was also reported in this study. The concentration of anti-nutritional factors and heavy metals in camelina seeds was below the maximum set limit for feedstuff. To conclude, the investigated Serbian camelina genotypes can be used as a valuable source of proteins, essential fatty acids and tocopherols in animal nutrition and has a great potential to replace conventional oilseeds.

Effect of inclusion of micronized camelina, sunflower, and flax seeds in the broiler chicken diet on performance productivity, nutrient utilization, and intestinal microbial populations.

Abstract
The aim of the study was to evaluate the effect of inclusion of micronized full-fat camelina, flax, or sunflower seeds in the diet for broiler chickens on the performance productivity, nutrient utilization, and composition of intestinal microbial populations and to assess the possibility of modification of the resistance of isolated bacteria to chemotherapeutic agents with different mechanisms of action. The use of micronized oilseeds improved the broiler chicken body weight (P = 0.035) and the FCR value (P = 0.045) in the final rearing stage by enhancement of the utilization of total protein and organic matter. Lactobacillus-Enterococcus spp., Bifidobacterium spp., Escherichia coli, and Salmonella spp. were isolated from small intestinal contents, and Enterobacteriaceae taxa were detected in the cecum and cloaca of the broiler chickens. The addition of micronized camelina seeds (CAM.IR) contributed to an increase in the Bifidobacterium counts in the small intestine, compared with the control treatment (P < 0.050). Escherichia coli bacteria were not isolated only in the CAM.IR treatment. Nitrofurantoin and chloramphenicol were the most effective agents against the isolates from the cecum and cloaca in all oilseed treatments, whereas streptomycin exhibited the lowest efficacy. In the CAM.IR and micronized sunflower seed (SUN.IR) treatments, there were higher counts of trimethoprim/sulfamethoxazole-resistant Enterobacteriaceae strains than in the control and micronized flax seed (FLA.IR) treatments (P < 0.05). There was a difference between strains isolated from the cecum and cloaca only in the FLA.IR treatment, i.e., increased tetracycline sensitivity was exhibited by strains isolated from the cloaca (13% vs. 50%), also in comparison with the control treatments (P = 0.054). In comparison with the CAM.IR and control treatments, reduced numbers of multi-resistant strains were found in the cloaca isolates from the for FLA.IR and SUN.IR variants. Micronized camelina, flax, and sunflower seeds can be used as part of an effective nutritional strategy focused on optimization of the efficiency of rearing broiler chickens, as they positively modify intestinal microbial populations and increase bacterial sensitivity to the analyzed chemotherapeutic agents.

Abstract
Background and Aim: Progressive antibiotic resistance has become the primary threat to public health. The search for alternative substances with similar effects is now a global challenge for poultry farming. The aim of this study was to investigate the action of the probiotic Bacillus cereus (BC) and coumarin (CO) on broiler productivity, biochemical indicators of blood, and muscular and liver tissues. Materials and Methods: The trial of this study included Arbor Acres cross broiler chickens that were grown up to the age of 42 days. The experiment was conducted on 200 broiler chickens divided into four experimental groups of 50 individuals each: The control group received ration without additives (main ration [MR]), the first experimental group received MR+BC, the second received MR+CO, and the third received −MR+BC+CO. A biochemical and hematological analyzer was used to estimate elemental concentrations using inductively coupled plasma mass spectrometry and inductively coupled plasma atomic emission spectrometry. Results: Inclusion of CO and CO+BC in the diet improved growth rates and reduced feed consumption (FC) per kg of live weight gain. Decreased white blood cell count, increased creatinine and triglycerides (CO), changes in aminotransferase and transpeptidase activity, and increases in chemical elements in the liver and pectoral muscles (BC+CO) were observed. The inclusion of BC+CO in the diet contributed to increases in a greater number of chemical elements in the liver (calcium [Ca], K, magnesium, Mn, Si, and Zn) and the pectoral muscles (Ca, Na, Co, Cu, Fe, Mn, Ni, and Zn). Conclusion: The inclusion of CO and CO+BC in the diet improves growth rates and reduces FC in broilers against a background of the absence of mortality during the experiment.

Abstract
The current study investigated the effects of thermal processing of the microwave technology on nutritive value, crude protein solubility, urease activity and amino acid profile on linseed grains. Samples were treated in a SAMSUNG GE82N-B microwave oven at 450W for 0 (L1), 60 (L2), 180 (L3), 300 (L4), and 420 (L5) seconds, respectively. Microwave treatment for 300 seconds showed a significant (p ≤ 0.05) decrease in activity urease comparing to raw linseed. The raw and treated linseed protein solubility index (PDI) show statistical differences (p ≤ 0.05) between all the treatments compared. High performance liquid chromatography (HPLC) analyses of samples differences in the amino acid composition between controls and experimental treatments showed that amino acids were not significantly affected (p ≥ 0.05), except isoleucine and leucine amino acid (p ≤ 0.05). From the results of the present study, it is possible to identify that the best method for improving linseed quality for animal feed is the application of microwave for 60 second (treatment L2). Our results indicate that microwave thermal processing or micronizing dry thermal processing of grains could be successfully used in large industrial feed production with a short period of time and the improved nutritional parameters of grains, increased shelf-life and the unchanged amino acid profile of treated grains.
