the effects of probiotics and antibiotics and fat type in diet on broiler performance were studied by using 900 one-day old ross 308 chicks in a three × three factorial arrangement with three types of fat (nonfat, three percent fatty acid and three percent soy oil) and three growth promoters (without gp, flavomycin and protexin) in completely randomized design with four replicates per each trea...

This study was conducted with broilers to evaluate the effects of growth-promoting antibiotic (flavomycin) and probiotic (7 bacterial species) supplementation in diets containing soybean oil or free fatty acids (FFA) on performance, morphological parameters of the small intestine, apparent digestibility of gross energy (GE) in the ileum, and apparent digestibility of fat in the ileum and total ...

the effect of silver nanoparticles as additive on broiler performance was investigated through employed of 312 day-old broiler chiks (arbor-acre plus) in a completely randomized design with 6 treatment diets each in 4 replicates. corn- soy based diets were formulated for starter, grower and finisher according to nrc (1994) recommendations. the silver nanoparticle solutions (2000 ppm) were added...

six hundred day old unsexed broiler chicks were used in a 35-day trial to compare the effects of soybean oil, palm oil and fish oil supplementation on the performance of broilers in terms of feed intake, weight gain and feed conversion. the chicks were randomly distributed following a completely randomized design in four groups having three replications per treatment. each treatment had 150 bir...

this experiment was conducted to evaluate the effect of emulsifiers such as lecithin and bile salts onbroilers performances fed diet containing vegetable fats. 192 male ross broiler chickens were randomlyallocated in a factorial experiment design of 3 × 2, consisting two sources of fat (four percent fatty acidsor soy bean oil) and three emulsifiers (none, one percent lecithin and 0.05 percent b...

The chicks were randomly distributed following a completely randomized design in four groups having three replications per treatment. Each treatment had 150 bir...

an experiment was conducted on broiler chickens to study the effects of conjugated linoleic acid (cla), fish oil, both at 7% of the diet, or their mixtures at 3.5% of the diet, on the performance, carcass traits and intestinal morphology of broiler chickens. the chicks fed with 7% fish oil or 7% cla diets, were found to have an inferior weight gain in grower and finisher phases, respectively. a...
