Influence of L-threonine Supplementation to Diets with Reduced Crude Protein on Feed Efficiency in Commercial Broilers

The effects of supplemental threonine on performance, carcass characteristics, immune response and gut health of broilers in subtropics during pre‐starter and starter period

“…Our present trial is in agreement with few others (Khan, Nawaz, & Zahoor, ; Kidd et al, ; Shan et al, ) who reported that the dietary supplementation of threonine significantly increased the feed intake between experimental groups. The dietary supplementation of threonine significantly increased the ADG between experimental groups (Estalkhzir, Khojasteh, & Jafari, ; Madapurada, Neraj, Sushma, Krishnamurthy, & Ananda, ; Majumder, Das Chowdhury, Zakir Hossain, & Islam, ; Zhang & Kim, ). The accelerated growth found in threonine supplemented groups might be related to the role of threonine, which is required for protein synthesis and maintenance of body protein turnover (Madapurada et al, and Ton et al, ).…”

The accelerated growth found in threonine supplemented groups might be related to the role of threonine, which is required for protein synthesis and maintenance of body protein turnover (Madapurada et al, and Ton et al, ). The accelerated growth rate in treatment groups showed the importance of adequate intake of feed and protein in terms of amino acids for muscle protein deposition, protein synthesis and maintenance of body protein turnover in addition to the calcium and phosphorous necessary for bone tissue formation during the experimental period.…”
