Effect of threonine and zinc alone or in combination on immunity and intestinal morphology of broiler chickens
Keywords:
broiler, immune response, intestinal morphologyAbstract
Broiler chickens' immune response may be affected by the body health; Therefore, this Study was aimed to evaluated the was aimed to investigate the effect of threonine(Thr.) from the jefo Co.Canada and zinc (Zn.) from the Zinpro Co.USA as an important factor that regulates intestinal amino acid metabolism. The experiment period was five weeks started from 7/12/2021 to 11/1/2022 carried out in special felid. A total of 200 straight run one-day broiler chickens (Ross 308) were divided randomly to four groups (50/group) with 2 replicates (25 birds/pen). The control group (CON.) fed basal diet without any additives. The second group was fed the basal diets with high level calculated (%0.9) Threonine. The third group was fed the basal diets with level calculated (% 0.1) Zinc. The fourth group was fed the basal diets with (% 0.9) Threonine and was fed the basal diets with (% 0.1) Zinc. Feed and water provided add libitum to the end of the study.
