“…In a study by Yu et al, [35] exposing broiler breeder to 250 gauss MF for 8 weeks resulted in a significant increase in their plasma glucose levels compared to the control group. The reduction in carcass percentage in all treated birds is in agreement with [36] who reported a significant decrease in body weight gain of meattype breeder eggs exposed to 18 Gauss MF at 50 Hz for 75 min. In contrast, Shafey et al [37] showed significant increase in the weight of rats exposed to MFs of 5 and 8mT for 3 weeks.…”

The objective of the present study was to evaluate the effects of magnetic technology including the exposure to magnetic field (MF) and/or consumption of magnetic water (MW) on the productivity of aged Japanese quail birds. The experimental laying flock consists of 160 females and 80 males of aged quails at 50 weeks of age that was used. Birds were divided into four equal treatments, each with 40 females and 20 males, and each treatment had four replicates (10 females and five males each). The first treatment served as control group consumed zero gauss water and did not receive MF exposure, the second group consumed 2000 gauss MW, the third group received 400 gauss MF exposure, and fourth group consumed 2000 MW and received 400 gauss MF exposure. The experimental period lasted for 6 weeks. The laying performance, hematological, biochemical, and hormonal variables were estimated and compared with control one. The results revealed a significant increase (P ≤ 0.05) in egg production, egg weight, hen day percentage, fertility, hatchability of total eggs, hatchability of fertile eggs, and hatching weight as well as, there was a significant decrease in embryonic mortality in all treated groups compared to control one. The highest values were seen in T4 among the treatments, with the exception of egg weight and hatching weight. A significant decrease in the relative weight of carcass and abdominal fat as well as and a significant increase in ovary, oviduct, and tests percentages were observed in all treated groups compared to control group. The highest decrease was showed in T4 among the treatments. Hematological parameters, plasma alkaline phosphatase enzyme activity, testosterone, and estrogen hormones were significantly increased, while total lipids, triglycerides, and cholesterol were significantly decreased in both sexes of all treated groups compared to control group. In relation to the immune response, the results of antibody sheep red blood cells-titers (log 2 ) were significantly improved in treated groups compared to control one. The superior increase was observed in T4. It can be concluded that applying MF with MW as an alternative technique to moulting program and was the most effective strategy to combat the decline in reproduction, physiological state, immune response, and mortality of aged Japanese quail. It also improved the productivity of aged laying Japanese quail birds by lengthening the production period of flock.

“…In contrast, other studies used different levels of vitamin E supplementation (0, 150, 250 and 350 mg/kg of diet) and reported no significant differences in feed consumption and feed conversion efficiency in their progeny generation 14,15 indicated an improvement in weight gain when selenium was added (0.4 mg/kg) to the diet of broiler at 1-6 weeks of age, (16) indicated no significant differences in weight gain when adding sodium selenite to broiler diets at a 1 mg/kg rate at 15-27 days of age. There are many global hybrids used widely in Iraq to produce broilers for local consumption, and sometimes the broiler industry imports chicks or eggs for hatchery, besides there are many enterprises that reared broiler breeders to produce hatching eggs, and there are many studies aimed to improve their performance in the Iraqi environment [17][18][19][20] .…”

Nutritional supplements have been commonly used in the poultry industry last few years. The study aimed to investigate the epigenetic effects of adding vitamin E and organic selenium to the diet of broiler breeders Ross-308 on their progeny meat production performance. The treatments included the control group fed with a standard diet without supplementation (T1), T2 using a standard diet supplemented with 500 mg of vitamin E / kg, T3 using a standard diet supplemented with 0.5 mg of organic selenium (Availa powder) /kg, and T4 using a standard diet supplemented with a mixture of vitamin E and organic selenium in proportions 500 and 0.5 mg/kg respectively. The eggs were collected from each treatment to obtain the progeny reared for 35 periods, and measurements were recorded for meat production and carcass traits. The results showed that the treatments had significant epigenetic effects on body weight at hatching. Hence, T2 had a significantly heavier body weight than T1, while no significant differences were observed between T3 and T4. The result of T2 recorded extremely high feed intake compared with T3. On the other hand, T3 and T4 recorded a hefty weight of breast parts compared with T1 and T2. In conclusion, organic selenium supplementation led to a significant increase in breast weight and a decrease in thigh part weight compared to the control group. In contrast, vitamin E supplementation led to an increase in chick weight at hatch, a reduction of total mortality and an improvement in feed conversion ratio compared to the control group. This refers to the epigenetic effects of organic selenium and vitamin E on progeny traits when added to the breeder diet. Keywords: Epigenetics, broiler, selenium supplementation, meat production
