Optimal application of organic zinc in drinking water to improve the immune responses and to balance the hormones in broiler breeder hens

Abstract

Zinc in antioxidant systems, strengthen the immune system are effective hormone. The purpose of this study, the effect of different levels of zinc on blood parameters, safety breeder hens were hormone. Methods: In this study 60 Ross 308 broiler breeder hens from week 19 to 31 were divided randomly into 5 groups. Birds of a diet based on corn and soybean meal with 110 mg per kg mineral supplements fed on. Used source of organic zinc (Znmethionine), who is drinking at levels of 0, 100, 200, 300 and 400 mg per liter in drinking water was used from the beginning of week 19. Each of the 5 treatments, 3 replicates each were 4 chickens. In the week of 26 (5% of production) and 31 (peak),blood samples from 12 birds per treatment were collected. Measured parameters included serum concentrations of FSH, LH, estradiol, cortisol, insulin, IGF-1 and IgY. In stage 5% of production, particularly on the amount of organic 300 ppm increase in serum LH. Serum insulin with the amount of organic 400 ppm on the stage and receive 5% of the organic content of 300 ppm at the peak of increased production. Serum cortisol amounts of organic 300 ppm on the stage and receive 5% of the peak value of 200 and 100 ppm on organic production declined. At peak production, getting 100 ppm Zinc serum IGF-1 was increased. In stage 5% of amounts 400, 300, 200 ppm on the organic increase in serum IgY. The results showed that the amount of organic ppm 300 for the production of drinking at 5% and the amount of the organic ppm 100 for beverage can production at the peak of egg production areas for improvement and provide immune response breeders.
