Abstract
Controlling feed intake is essential to providing ideal nutrition and helping poultry reach their maximum potential for growth and development. The current research looked at how L-leucine and L-tryptophan affected layer chicks' meal intake. Leucine and tryptophan were administered intracerebroventricularly (ICV) to 4-day-old layer chicks, and feed intake was monitored at different time intervals. Our findings demonstrated that L-leucine administration by ICV enhanced feed intake up to two hours after treatment (P 0.05). On the other hand, L-tryptophan (10 or 100 g) had no discernible impact on feed consumption. These results showed that L-leucine may impact appetite inside the hypothalamus and that orexigenic and anorexigenic Neuropeptide genes may be directly involved in these effects.
