The aim of this study was to evaluate the effect high doses calcium bentonite on blood parameters, anticoccidial activity and intestinal histology broiler chickens. Three undred sixty one-day old broilers were distributed into three treatments (T+VE, T-VE, TB )with replicates. Amprolium added feed positive control group, powder nothing T-VE group. Coccidiosis induced day 14, birds kept until 49...

The study aimed to investigate the dose tolerance of enzymatically degraded feather meal (EFM) in diet, and effect two-stage fermented on growth performance amino acid digestibility broilers. In trial 1, 160 one-day-old broilers were randomly assigned into 0, 10, 15, 20% EFM groups. 2, control, 10% EFM, Bacillus subtilis var. natto N21 + B. coagulans L12 (BBEFM), Saccharomyces cerevisiae Y10 (B...

background: nutritional strategies targeting improvement of poultry performance and disease prevention are currently being developed and in this respect the dietary intake of spiced essential oils and pre-biotics in raising broilers is receiving attention. objectives: this study was conducted to compare the effects of diet containing ginger essential oils (geo) and mannan-oligosaccharide (mos) ...

A study was conducted to evaluate the molecular and cellular immunomodulatory effects of a Saccharomyces cerevisiae fermentation product (Original XPC, Diamond V) in broilers. Our lab has previously demonstrated that broilers fed XPC generate faster and stronger antigen-specific humoral immune responses to Newcastle disease virus (NDV) vaccination. This study aims at investigating the mechanism...

Objective: An experiment was conducted to investigate the effects of citrus brown snail powder as a source of calcium on growth performance, tibia characteristics, immune response and blood metabolites in broiler chickens.  Methods: One hundred and eighty 1-day old chicks were randomly distributed into four treatments, each of which had three replicates. Each replicate contains 15 chicks. The t...

This study was conducted to evaluate the carcass yield, abdominal fat deposition and chemical compositions of thigh and breast muscles of male Arian broilers fed three different lysine levels of 1) high lysine (110% NRC), 2) standard level suggested by National Research Council (NRC) and 3) low lysine (90% NRC) based on two expression ways of amino acid contents of feedstuffs, as total amino ac...

a total of 160 day-old male broiler chickens (ross 308) were divided in a completely randomized design experiment, and assigned to 8 treatments and 4 replicates in their experimental units (cages). treatments included: t1: basal diet with no additional methionine, t2: basal diet plus 0.06, t3: basal diet plus 0.11, t4: basal diet plus 0.17 % of dl-methionine, t5: basal diet plus 0.06, t6: basal...

Furosemide (FURO) is a diuretic and a putative pulmonary vasodilator that, when added to broiler diets, previously has been shown to reduce the cumulative pulmonary hypertension syndrome (PHS) mortality induced by cold temperatures. The objective of the present study was to evaluate the influence of dietary FURO on the pulmonary vasculature in broilers undergoing chronic or acute unilateral pul...

Two experiments assessed the efficacy of in ovo administration of insulin-like growth factor-I (IGF-I) to enhance skeletal muscle development and improve feed efficiency of broilers. Hatching eggs were divided into three groups: uninjected control, vehicle-injected control, and recombinant human (rh) IGF-I (100 ng per embryo). Eggs in Experiment 1 were injected on Day 1, 4, or one of Day 7 thro...
