This study was carried out to determine the effect of L-arginine (L-Arg) levels in diet at the starter, grower and finisher phases on immune response, organ development, nitric oxide (NO) metabolism and colon motility in broilers. A total of 500 one-day-old Ross-308 broiler chickens of mixed sex were separated into one Arg-deficient group and four experimental groups. Each group was then divide...

The effects of organic and inorganic sources and concentration (0 and 0.3 mg per kg of diet) of Selenium (Se) on growth performance, blood biochemical and immune system were evaluated in broiler chickens. Chickens were fed corn-soy-based diets formulated to 8 dietary treatments containing no added Se (negative control), negative control plus yeast (positive control), and 6 diets had 0.3 mg/kg o...

Abstract The threat of the development an antibiotic resistant bacterium necessitates investigation for alternative feed additives. Probiotics are known to confer a health benefit animal and affect production through increased nutrient digestibility. aim this study was investigate bacterial composition rumen South African feedlot cattle when supplemented with Bacillus probiotic. Twenty-four Bon...

A 42-d floor pen study was conducted to compare broiler (Ross x Ross 308) performance and carcass measurements when fed diets containing meal produced from glyphosate-tolerant soybeans (MON 89788) with those of broilers fed diets containing meal produced from control soybean (A3244) that has similar genetic background to MON 89788. Soybean meal produced from 6 conventional soybean varieties was...

satureja hortensis is a popular herb in most regions of the world with leaves used as seasoning. evidence shows that this plant contains phenolic components such as thymol and carvacrol with a relatively wide spectrum of antimicrobial activity. this study aimed at evaluating the efficacy of s. hortensis plant powder as an alternative to antimicrobial growth promoters in broiler diets. the plant...

A total of 80 day old British United Turkeys were subjected to four dietary treatments at varying levels of niacin + yeast. Each treatment had 20 birds of 4 replicates with 5 birds in each replicate. Niacin + yeast (240 ppm niacin + 1.5g/kg yeast and 200 ppm niacin + 1.5 g/kg yeast, at the starter, grower, and finisher phase) showed significant effect on body weight gain, serum Low Density Lipo...

This study examined effects of incremental levels sugarcane derived polyphenol on most commonly used cereals in the poultry feed industry; wheat and maize. Both rapidly digestible starch, which is usually digested completely than protein itself whereas slows down glucose absorption rat without compromising intake. Polyphenol may enhance depositing muscle broilers due to synchronous availability...
