BACKGROUND Breastfeeding is associated with a variety of positive health outcomes in children and is recommended exclusively for the first 6 months of life; however, 50-70 % of infants in the US are formula-fed. To test the hypothesis that immune system development and function in neonates and infants are significantly influenced by diet, 2-day old piglets were fed soy or milk formula (n = 6/gr...

The present experiment was conducted to evaluate the effects of organic acids and phytase enzyme supplementation on performance and intestinal histomorphology of broilers. The experiment was done in a factorial arrangement 2 × 2 × 2 based on completely randomized design with eight treatments, five replicates with 12 chicks in each until 42 days of age. Diets included natural vinegar (0 and 2%),...

introduction antibiotic feed additives have long been used as growth promoters in poultry nutrition. however, concern has been expressed about the potential development of antibiotic resistant bacteria (25). consequently, the animal feed industry, exposed to increasing consumer pressure to reduce the use of antibiotic growth promoters in poultry diets, has to find alternative feed additives. ma...

A total of 540 one-day old male broilers Ross 308 were allocated to 6 treatments in a completely randomized designed with a 2×3 factorial arrangement (aflatoxin B1 (AFB1) and probiotics) with 6 replicates and 15 birds in each. Factors include aflatoxin B1 (control, 500 ppb) and probiotics (control, 108 cfu/mL Bacillus sp. MBIA2.40, 0.2 g Gallipro per kg). Results showed that adding 500 ppb AFB1...

A 4 × 2 factorial experiment was conducted to investigate the effect of dietary supplementation levels (0, 5 and 10 g/kg) chamomile flower powder a level (60 mg/kg) salinomycin on performance gut health broiler chickens under coccidiosis challenge. total 320-day-old Ross 308 broilers were assigned eight treatments four replicates with 10 birds. Oral inoculation challenged groups Eimeria ...

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...

Twenty-four 21-d-old Arbor Acres (AA) broilers with similar BW were randomly assigned into 4 groups to investigate the effects of stress on the absorption of glucose in the intestine of broilers and its mechanisms. In this study, dexamethasone (DEX), an analog to glucocorticoid secreted when animals suffer from stress, was chosen to simulate the effects of glucocorticoid. Broilers were injected...

We studied the effects of heat-killed Tsukamurella inchonensis on immune parameters and intestinal structure in mice. Mice were treated with three doses of bacteria (5 × 107, 1 × 108 and 2 × 108 CFU/mouse) consecutively for seven days. Body weight, delayed type hypersensitivity response, relative organ weight, and haemagglutination titres were studied in different groups of animals. Villus heig...
