Two experiments were conducted to study the effect of adding soy-lecithin or xylanase low-energy diet on broilers growth performance, nutrient digestibility, intestinal lipase enzyme activity and economical efficiency. A total number 256 unsexed Cobb500 broiler chicks, a day old, classified into two equal experiments, 128 chicks each (4 treatments × 4 replicates 8chicks). In experiment, divided...

At hatch, 360 one-d old Cobb500 male broilers were placed in battery cages to determine the effect of soybean meal (SBM) from different Midwest varieties on growth performance broilers. There 6 per cage and 15 replicates treatment. Dietary treatments cons0isted 1 4 sources varying quality determined by crude protein (CP) content processed into SBM. Two consisted soybeans a similar region either...

Eimeria species cause the intestinal disease coccidiosis, most notably in poultry. While the direct impact of coccidiosis on animal health and welfare is clear, its influence on the enteric microbiota and by-stander effects on chicken health and production remains largely unknown, with the possible exception of Clostridium perfringens (necrotic enteritis). This study evaluated the composition a...

Two experiments were conducted to evaluate the effects of a novel synthetic emulsifier product (AVI-MUL TOP) on the growth performance of chickens for fattening and weaned piglets. The emulsifier product consists of 50% vegetal bi-distillated oleic acid emulsified with 50% glyceryl polyethyleneglycol ricinoleate. In experiment 1, 480 1-day-old female Cobb500 chickens for fattening were assigned...

Campylobacter is one of the major foodborne pathogens that result in severe gastroenteritis in humans, primarily through consumption of contaminated poultry products. Chickens are the reservoir host of Campylobacter, where the pathogen colonizes the ceca, thereby leading to contamination of carcass during slaughter. A reduction in cecal colonization by Campylobacter would directly translate int...

This study aimed to evaluate the comparative effects of aflatoxin-contaminated corn on the thymus and bursa of Fabricius (BF) in chickens by detecting histopathological lesions, cell cycle phase distribution and apoptosis. A total of 900 COBB500 male broilers were randomly allocated into five groups. The experiment lasted for six weeks and the five dietary treatments consisted of uncontaminated...

The study was conducted with the objective of determining effects dietary replacement soybean meal graded levels linseed on selected blood parameters, meat composition, fatty acid profiles, and quality broiler chickens. Cobb500 broilers were fed diets containing at 0% (T1), 6.5% (T2), 13% (T3), 19.5 (T4), 26% (T5), replacing to 100% in compound rations for 45 days. experiment using a completely...

in this study, effect early age feed restriction and thermal conditioning on growth ,carcass characteristics broiler chickens subjected to heat stress was evaluated. three hundred chicks (cobb500) were randomly divided into four equal groups as treatments including thermal conditioning group (tc), feed restriction-thermal conditioning group (tcfr), feed restriction group (fr) and control group ...

this experiment was conducted to study of using different level and treatments of common vetch (visia sativa) on broiler performance in a completely randomized design with 10 treatments, 4 replications and 10 chicks in each, using 400 cobb500 broiler chicks. treatments were: corn-soybean meal based diet as control , and unprocessed or processed common vetch seed (water or autoclaving) each at 3...
