Abstract
The objective of this study was to investigate the effect of using some sources of antioxidants on the productive and reproductive performance of turkeys. This study was carried out at Mehalet Mousa Animal Production Research Station, Kafr El-Sheikh, belonging to the Animal Production Research Institute, AgriculturalResearchCenter, Ministry of Agriculture, Egypt. A total of 84 Bronze female turkeys, 32 weeks of age were used. The birds were randomly distributed into 7 experimental groups; each consisted of three equal replicates. The birds were individually housed in battery cages. The experimental period lasted 12 weeks (from 32 to 44 weeks of age). The birds were fed a yellow corn-soybean meal-based diet, supplemented with two antioxidants, zinc and selenium of three sources organic, inorganic and nano forms. The experimental groups were fed one of the following diets: (1) a basal diet without added zinc or selenium; (2) inorganic zinc (zinc oxide) 100 mg/kg diet; (3) organic zinc (zincmethionine) 100 mg/kg diet; (4) nano zinc (zinc oxide nanoparticles) 40 mg/kg diet; (5) inorganic selenium (sodium selenite) 0.3 mg/kg diet; (6) organic selenium (selenomethionine) 0.3 mg/kg diet; (7) nano selenium (selenium nano-particles) 0.15 mg/kg diet. The results obtained can be summarized as follows. Dietary supplementation with inorganic, organic and nano forms of zinc and selenium significantly (P≤0.05) increased serum levels of total protein, concentrations of blood haemoglobin, egg fertility, hatchability of eggs in turkey hens, and significantly (P≤0.05) improved feed conversion ratio as compared to that of the controls. Dietary supplementation with inorganic, organic and nano forms of zinc and selenium significantly (P≤0.05) decreased feed consumption, serum levels of total lipids and cholesterol as compared to those of the controls. Supplementation of organic and nano forms of zinc and addition of inorganic, organic and nano forms of selenium to diets of laying turkey hens significantly (P≤0.05) increased hen-day egg production rate and egg weight as compared to those of the controls. Dietary organic and nano forms of zinc and selenium of turkey hens caused significant increases (P≤0.05) in serum antibody titres against Newcastle disease virus and improved immunity, and exhibited a significant increase in relative weight of spleen and oviduct length compared with their control group. Turkey hens fed diets supplemented with organic and nano Se produced eggs with better albumen quality and egg shell quality as measured by Haugh units and egg shell thickness as compared to that of the control turkey hens. There were no significant differences among the different dietary treatments in relative weights of egg components, egg shape index, egg yolk index, yolk color score, relative weights of carcass yield, liver and heart of turkey hens. It can be concluded that dietary supplementation with organic and nano forms of zinc and selenium can induce beneficial effects on productive and reproductive performance of turkey hens.
