Effects of fermented cottonseed meal on the growth performance, gastrointestinal microflora population and small intestinal morphology in broiler chickens

Abstract

1. This experiment was conducted to evaluate the effects of replacing dietary cottonseed meal (CSM) or fermented cottonseed meal (FCSM) for soya bean meal (SBM) on growth performance, carcass characteristics, gastrointestinal microbial populations, and intestinal morphology of broiler chickens. 2. CSM was fermented with Bacillus subtilis, Aspergillus niger and A. oryzae for 7 d. A total of 300 one-d-old male Ross 308 broiler chickens were used in a 42-d experiment in which the birds were randomly allotted to one of 5 dietary treatments (containing 0%, 10% and 20% CSM or FCSM) in a completely randomised design. Birds were reared on litter floor and had free access to feed and water during the experiment. 3. Results indicated that the fermentation process significantly reduced crude fibre and free gossypol, while it increased crude protein content and lactic acid bacteria (LAB) count in CSM. 4. The use of FCSM instead of CSM significantly improved growth performance of broilers. The abdominal fat yield in treatments containing FCSM was significantly lower than in the other treatments. The increase in the population of LAB in the crop and decrease in the population of coliforms in the ileum of birds fed on diets containing FCSM were more significant than in other birds. Villi in the duodenum and jejunum of the birds fed on diets containing FCSM were significantly higher than for the other experimental groups. 5. The positive effects of diets containing FCSM on growth performance and intestinal health of broiler chickens showed that this processed source of protein can serve as an appropriate alternative for SBM in diets for broiler chickens.

Effect of dietary supplementation of whey powder and Bacillus subtilis on growth performance, gut and hepatic function, and muscle antioxidant capacity of Japanese quail

“…They indicated that these substances could stimulate the proliferation of lactobacilli species. Meanwhile, BAS spores are capable of providing an anaerobic environment for the growth and proliferation of lactobacilli species by uptaking the oxygen present in the gut after germination (Jazi, Boldaji, Dastar, Hashemi, & Ashayerizadeh, ). In addition, BAS disturbs the growth of pathogens by synthesizing antimicrobial substances including amicoumacin, bacilysin, bacillaene, bacillomycins, and bacteriocin‑like substances (Suva et al, ).…”

Characterization of Soluble Glandless Cottonseed Meal Proteins Based on Electrophoresis, Functional Properties, and Microscopic Structure

“…Cottonseed meal (CSM) is an agroindustrial byproduct of the oil industry with high protein content and has a great potential of being used as a protein source (Gao, Cao, & Hi, ). Because of the high concentrations of gossypol, an antinutritional compound, CSM, has been used only for ruminant feed (Berardi & Goldblatt, ; Martinez, Berardi, & Goldblatt, ) or fermented for broiler chickens (Jazi, Boldaji, Dastar, & Hashemi, ).…”

Effects of peanut meal extracts fermented by Bacillus natto on the growth performance, learning and memory skills and gut microbiota modulation in mice

“…The Chao1 value is often used to estimate the total number of species in a sample, while Shannon indicates the α-diversity of intestinal microflora. The higher the Shannon is, the more evenly the distribution of microflora species is (22) . As depicted in Fig.…”

“…The regulation of gut microbiota (GM) has become an important way for humans to treat gastrointestinal and metabolic diseases (20) , and it plays an important role in the intestinal morphology, immunity, digestion and health of the host (21,22) . A healthy GM ecology is critical for the establishment of tissue homeostasis health.…”
