abstract

the effect of feeding fermented cottonseed meal on performance, carcass characteristics and blood serum lipid profile was studied in a completely randomized design with five treatments, five replicates and 12 birds per replication using 300 male ross 308 broiler chicks. raw cottonseed meal was fermented with a liquid mixed culture containing bacillus subtilis, aspergillus niger and aspergillus oryzae with a ratio of 1:1.2. after seven days of fermentation, free gossypol was reduced from 584.33 to 68 mg/kg. the experimental treatments included replacing 0, 10, and 20 percent of the raw or fermented cottonseed meal by the soybean meal in the diet. the use of fermented cottonseed meal in the diet improved weight gain and feed conversion ratio of broilers compared to the raw cottonseed meal (p

Effect of Different Levels of Cottonseed Meal Bioactive Peptides on Production Efficiency and Serum Antioxidant Activity of Broiler Chickens

Cottonseed meal was hydrolyzed using five types of enzymes: alkalase, chymotrypsin, pepsin, trypsin, and pancreatin. The experiment was carried out using 240 male broilers of Ross 308 strain in a completely randomized design with 4 treatments and 5 replications from 1 to 35 days of age and during the starter (1-15 days) and grower (16-35 days) phases. The experimental diets were the control die...

Effect of the Replacement of Soybean Meal by Rubber Seed Meal on Growth, Economics and Carcass Characteristics of Broiler

The experiment was to study the effects of replacing soybean meal by rubber seed meal on growth, economics and carcass characteristics of broiler. A total of 150 day-old commercial broiler (Cobb-500) was reared for a period of 35 days. There were five treatments including T0 (without rubber seed meal), T1 (10% rubber seed meal), T2 (20% rubber seed meal), and T3 (30% rubber seed meal) and T4 (4...
