Effects of Soy Protein Concentrate in Starter Phase Diet on Growth Performance Blood Biochemical Indices Carcass Traits Immune Organ Indices and Meat Quality of Broilers

摘要

It is well known that early nutrition plays an important role in determining changes in later physiology. Therefore, in order to promote the early growth of broilers, it is necessary to feed diets with high concentration of nutrients and high digestibility in the early stage after hatching. Since soy protein concentrate (SPC) has the characteristics of low content of antinutritional factors (ANFs), high digestibility and high amino acid content, we evaluated whether supplementation of SPC in starter diet could promote the later growth of broilers without changing the diets nutritional level (the same Metabolizable energy (ME), crude protein (CP) and amino acids (AAs)). The results showed that supplementing SPC in starter diet could improve the growth performance, carcass traits and immune organ indices of broilers. The results are very promising and SPC can be considered as a starter diet additive for commercial use. However, the mechanism of adding SPC in starter diets to improve broiler performance needs further study.
