Additional Valine and Isoleucine Impact Growth Performance, Intestinal Health, and Muscle Growth in Broilers Under Necrotic Enteritis Challenges.

ABSTRACT: The current study aims to investigate the effects of additional valine and isoleucine in different necrotic enteritis (NE) challenge intensities. A total of 648 seven-day-old male Cobb 500 were allotted to nine treatments with six replicates. Two different NE intensity experiments (Exp-1 and Exp-2) were conducted. The five treatments for each NE experiment were as follows: (1) non-challenged shared control (NC), (2) NE challenge (NE), (3) 130% additional valine (VAL), (4) 130% additional isoleucine (ILE), and (5) 130% valine and isoleucine (MIX). In both experiments, all NE-challenged groups had decreased body weight gain compared to the NC group (p < 0.05). The ILE group in Exp-1 had further reduced body weight compared to the NE group on day 21 (p < 0.05). No significant di
