Effects of the bioactive amino acids leucine and tryptophan on feed intake in layer chicks

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.
