“…The marginal improvement found with the fermented cake + enzyme may be attributed to the combination of fermentation process and enzyme degradation of the fibre that made nutrients available to the birds. This is in agreement with Babalola et al [7] who reported improved nutrient availability to pullet chicks fed β-xylanase supplemented castor seed meal diet.…”

The effects of treatment methods on the nutritive value of cotton seed cake (CSC) for laying hens were examined. Olympia laying hens (n = 96) were assigned randomly to a 2 × 3 factorial combination of fermented or unfermented CSC supplemented with enzyme, Vitamin E and ferrous sulphate over a 4-week feeding period. CSC was incorporated at 15% in the diets. Results showed no significant differences (P > 0.05) in feed intake, body weight gain and egg weight due to treatments. However, hen-day egg production was significantly reduced (P < 0.05) among dietary treatments compared with the control. Layers fed on unfermented CSC + Vitamin E and unfermented CSC + FeSO 4 had the lowest (P < 0.05) values for packed cell volume and haemoglobin. Treatment differences in red blood cell and white blood cell were not significant (P > 0.05). Serum concentration of total protein among dietary treatments was lower (P < 0.05) than the control, while albumin and cholesterol values were similar (P > 0.05) for all treatments. Generally, activities of alanine and aspartate aminotransferases increased (P < 0.05) among CSC dietary treatments compared with the control diet. The interaction between CSC form and additives had no significant effect on any of the parameters. The results of this study indicate that the treatment methods employed for CSC could not significantly improve its nutritive value for egg production at 15% level in the diet of laying hen.

“…There is another problem as the cake contains a high level of fibre, perhaps 23% because undelinted seeds are used in the processing [5]. This high fibre content has limited the extent to which it can be used in the diets of poultry which lack the appropriate enzymes capable of degrading fibre [6,7].…”

“…1 The use of antibiotics as growth promoters and for prevention and treatment of diseases has become commonplace as poultry producers have adopted intensive farming systems. However, there is growing concern regarding the possible build-up of antibiotic residues in animal products, which can be harmful to consumers, and the development of drug-resistant bacteria, attributed to continuous feeding of antibiotics at sub-therapeutic levels.…”

BACKGROUND: Probiotics are being developed for use in animal feed to enhance production performance and prevention of gastrointestinal infections. The ban on using antibiotics as growth promoters, antibiotic resistance and the inherent problems of developing new vaccines make a compelling case for developing alternatives for in-feed antibiotics. The alternatives of choice have to be considered under the environmental conditions of the animal. Among the probiotics in use today, Lactobacillus has been shown to play a vital role in disease prevention, immune enhancement, improved growth and carcass yield in poultry. The present study investigates the effect of Lactobacillus bulgaricus (LB)-based probiotic on the growth performance, nutrient digestibility and immune response of broilers under tropical environmental conditions. RESULTS: Broilers fed LB diets consumed more feed (P < 0.05) and had greater body weight gain than the control group. Feed/gain ratio improved significantly (P < 0.05) with the 20, 40 and 60 mg kg −1 LB diets compared with the control or 80 mg kg −1 LB diet. The apparent digestibilities of nitrogen and fat increased with LB supplementation. However, there was no significant difference (P > 0.05) in fibre digestibility. White blood cell count increased significantly in broilers fed higher levels (>40 mg kg −1 ) of LB compared with the control group. Antibody production measured as antibody titre against Newcastle disease vaccine showed a curvilinear response over the range of LB concentrations examined. CONCLUSION:The results indicate that LB addition to broiler chick diets significantly improved growth performance, increased nutrient digestibility and stimulated humoral immune response.

“…To confirm this assumption, we conducted an experiment to examine the effect of A. awamori on growth performance, digestibility and skeletal muscle protein metabolism in broilers. Many antibiotics have been used to promote animal health and to improve utilization of nutrients and growth performance in poultry (Babalola et al 2006). However, there is strong public and governmental concern about the increasing prevalence of resistance to antibiotics in disease-causing bacteria because many antibiotics now available to treat human diseases will become ineffective in the future (Casewell et al 2003).…”

This study was conducted to show that dietary supplementation of a fungus, Aspergillus awamori called Koji in Japan, reduces skeletal muscle protein breakdown and stimulates growth in broiler chickens. A total of 30 chicks at 15 days of age was divided into control and two treatment groups (10 birds per treatment). Control group was fed basal diet and treatment groups were fed the basal diets supplemented with A. awamori at levels of 0.05% and 0.2%. The birds were raised for 12 days from 15 to 27 days of age and then the effect on growth, organ weights and plasma 3-methylhistidine concentration and digestibilities of protein and energy was evaluated. The messenger RNAs (mRNAs) of atrogin-1, ubiquitin, proteasome, m-calpain, µ-calpain, β-actin, myosin and pax-7 in the breast muscle were also measured. Body weight gain and breast muscle weight were increased, although feed intake was decreased by the fungus and thus feed efficiency was increased. Protein and energy digestibilities were increased. Furthermore, plasma 3-methylhistidine concentration was decreased by the fungus. The mRNAs of atrogin-1, ubiquitin, proteasome, m-calpain and µ-calpain were all decreased. The mRNA of β-actin but not myosin and pax-7 was slightly increased by the fungus. In conclusion, feeding A. awamori improves growth performance because skeletal muscle proteolytic activity is reduced and digestibilities of energy and protein are increased.
