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

Abstract

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.

Evaluation of Clostridium autoethanogenum protein as a new protein source for broiler chickens in replacement of soybean meal

“…The chemical composition, ileal protein, and amino acid digestibility of CAP were analyzed, and the results were presented in Table 1 (chemical composition), Table 2 (ileal protein digestibility), and Table 3 (amino acid digestibility). The analysis methods of chemical composition, ileal protein, and amino acid digestibility were referenced on articles published in our laboratory [ 13 ].…”

Dietary Replacement of Soybean Meal with Zanthoxylum bungeanum Seed Meal on Growth Performance, Blood Parameters, and Nutrient Utilization in Broiler Chickens

“…The above amino acid contents were analyzed in a fully automated amino acid analyzer (Hitachi L-8900, Tokyo, Japan). The premix, feeding management, and vaccination of broiler chickens were the same as previously published [19]. 1 The numerical value represents the measured content of nutritional components.…”

“…At 21 and 42 days of age, two broilers with similar weights were selected in each replicate for blood collection from the brachial wing vein after a 12-h fasting period. The determination indicators and method for serum were the same as those previously published [19].…”
