Evaluation of the Application Value of Cottonseed Protein Concentrate as a Feed Protein Source in Broiler Chickens.

Simple Summary: Cottonseed protein concentrate (CPC) is a novel plant protein source that has been developed using advanced cottonseed processing technology. It was extensively utilized as a replacement for fish meal in feed within the aquaculture industry. However, there was limited research on using CPC as a protein source to replace soybean meal in broiler diets. This study conducted a comprehensive analysis of the chemical and amino acid composition of CPC, and assessed its protein and amino acid digestibility, metabolizable energy value, and net energy value in the broiler chickens. Additionally, the experiment examined the effects of replacing 25% and 50% of soybean meal in feed with CPC on the growth performance, blood parameters, antioxidant capacity, and immunoglobulin content of broiler chickens. These findings provide valuable insights into the potential use of CPC as a substitute for soybean meal in broiler feed formulation. Cottonseed protein concentrate (CPC) has the function of replacing soybean meal to maintain normal animal growth and development. This study involved 180 Arbor Acres (AA) broilers, which were randomly assigned to three different treatments. Each treatment had six replicates, with each replicate consisting of 10 chicks. The control group was fed a basal diet, while the CPC-1 and CPC-2 groups used CPC to replace 25% and 50% of the soybean meal in the basal diet, respectively. The study showed that replacing soybean meal with 25% CPC in broilers' diets can maintain normal growth, while substituting 50% of soybean meal with CPC negatively affects the growth and development of broiler chickens. Furthermore, the CPC-1 group showed a significant increase in serum total antioxidant capacity, superoxide dismutase enzyme activity, and immunoglobulin content, along with a decrease in malondialdehyde content. Based on the research results mentioned above, it was speculated that CPC has the potential to replace around 25% of soybean meal in broiler feed without causing any negative impact on growth performance. This suggests that CPC could be a viable alternative to soybean meal in broiler diet. [ABSTRACT FROM AUTHOR]
