Abstract:
The essential amino acids are one of the dietary factors affecting egg size, total solids, and internal egg quality characteristics. Threonine is an essential amino acid for birds as it is involved in a variety of intermediaries for protein metabolism. After methionine and lysine, threonine is considered the third-limiting amino acid in poultry. The availability of cost-effective synthetic threonine since 2002–2003 has made it possible to reduce the dietary CP requirements in animal diets, thus meeting precision nutrition demands. Our experiment aimed to determine the effect of L-Threonine on egg production and quality parameters in laying hens. The effect of dietary supplementation of L-Threonine at various levels (0.2%, 0.4%, 0.6%, and 0.8%) on production performance and egg quality traits for 12 weeks of administration in white leghorn birds resulted in improvements in production percentage, egg weight and egg mass, Haugh Unit, and Shape Index in white leghorn birds. In comparison to other treatments, the 0.4% threonine supplemented group produced the best results and could be recommended for laying birds.
