Comparison of the Nutritional Effects Citric Acid-Based Acidifiers Produced with a Commercial Acidifier on Performance, Blood Metabolites, Small Intestine pH Values and Morphology in Broiler Chickens
this study was carried out to evaluate the effect of onion extract on growth performance, carcass characteristics and some blood metabolites in ross and cobb broiler chickens. one hundred sixty, 1-d-old broiler chickens (mean initial weight: 36.5 ± 1 g) of male sex (ross-308 and cobb) were randomly conducted as randomized complete design with 4 treatment and 4 replication. the experimental grou...
to study the anticoccidial and antioxidant effects of garlic powder (gp) and total sulfur amino acid (tsaa) on growth performance, faecal oocyst output, oxidative stress indicators and antioxidant status markers in broiler chickens, a 2 × 2 × 2 splitplot-factorial arrangement of treatments was used. a total of 480-day-old male broiler chickens were equally assigned to two plots. two hundred for...
This experiment was conducted to study the effect of different levels of levamisole on performance and related parameters with immune system in Cobb 500 strain male broilers. The experiment was carried out a completely randomized design, with 300 male broiler chickens in four treatments and five replicates 15 birds/replicates. The experimental groups consisted of zero, 2.5, 5 and 7.5 mg pe...
OBJECTIVE This experiment was conducted to investigate the effects of dietary supplementation with marigold extract on growth performance, pigmentation, antioxidant capacity and meat quality in broiler chickens. METHODS A total of 320 one-day-old Arbor Acres chickens were randomly divided into 5 groups with 8 replicates of 8 chickens each. The chickens of control group were fed with basal die...
The objective of this study was to investigate the effect of dietary supplementation with microbially-fermented rice bran on growth performance in broiler chickens. A total of one hundred and twenty 1-day-old broiler chickens, were randomly assigned to 5 dietary treatments in cages of 4 chicks each; each treatment had 6 replicate cages. A basal diet, formulated to be adequate in energy and nutr...
Coccidiosis control programs such as vaccines or in-feed anticoccidials are commonly practiced in the poultry industry to improve growth performance and health of commercial broiler chickens. In this study, we assessed the effects of various coccidiosis control programs (e.g., in ovo vaccination, synthetic chemicals, and antibiotic ionophores) on immune status of broiler chickens vaccinated aga...
background: use of synbiotic and zinc sources had synergetic effects on broiler chickens performance and immune response improvements. objectives: this experiment was carried out to evaluate the effect of synbiotic and zinc sources on broiler chickens performance, immune response and gut morphology. methods: a total of 780, one-day old male broiler chicks were randomly assigned in factorial met...
The effect of dietary Bacillus-based direct-fed microbials (DFMs; eight single strains designated as Bs2084, LSSAO1, 3AP4, Bs18, 15AP4, 22CP1, Bs27, and Bs278, and one multiple-strain DFM product [AVICORR]) on growth performance, intestinal lesions, and innate and acquired immunities were evaluated in broiler chickens following Eimeria maxima (EM) infection. EM-induced reduction of body weight ...
Barley consumption is limited in broiler chicken diet due to their β. glucanas polysaccharide content. The application of synthetic enzymes in poultry diet can increase the barley content. The purpose of this experiment is to study the effect of enzyme supplement-β-glucanas on the performance of broiler chickens, percentage of abdominal fat, intestine weight and economic evaluation of productio...
