The inclusion of low phytate grains in poultry diets can reduce the phosphorus (P) content of poultry feces, but their influence on fecal P composition is not well established. To assess this, 100 male broiler chicks (21 days old) were fed dietary treatments based on either a wild-type barley or one of three low phytate mutant barleys with 59, 62 and 99% reductions in phytate P, compared with t...

Lighting programs that provide longer daylength as a broiler ages reduce the incidence of ascites and sudden death syndrome. Birds given this type of program often have an increased incidence of carcass scratches due to increased bird activity. The turkey industry uses microwave technology to restrict claw growth and reduce carcass scratches. One concern is that the treatment may reduce bird gr...

Salmonella enteritidis, phage type 4 (SE PT4), was isolated from five of six 27-wk-old layer chickens submitted for necropsy from a flock of 43,000. Bacteriologic and epidemiologic investigations on the ranch revealed that five of the eight flocks (n = 176,000) were infected. The prevalence of SE PT4 in randomly selected healthy birds ranged from 1.7% (in caged birds) to 50% (in free-range bird...

the present study was carried out to examine the effects of a vitamin premix (vp) reduction or withdrawal from finisher diet (29-43 days) on performance, immuno-competence, and characteristics of leg bones and meat lipid oxidation of chickens fed on corn-soybean meal based diet. a total of 900 male broiler chickens (ross 308) were allocated to five treatment groups (0, 33%, 66%, 100% and 133% v...

effects of chromium nano particles (nanocr) on performance and meat quality of japanese quail under physiological stress was determined by  using 360 birds in a completely randomized design with six treatments, four replicates and 15 birds per each, during  17- 35 d of age. the tratments were negative control (non-stressed), and five groups under physiological stress which fed on diets suppleme...

One hundred and eighty 28-days-old Arbor Acres broiler birds were utilized in a 28 day experiment to investigate the effect of replacing bone ash with eggshell meal in the diet of broiler birds on their nutrient digestibility and blood parameters. Five experimental diets tagged T1, T2, T3, T4 and T5 were formulated to be isocaloric (2865.53 kcal ME/kg) and isonitrogenous (20% crude protein) suc...

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...

Four hundred fifty day old unsexed broiler chicks were used in a 35-day trial at Chittagong veterinary and animal sciences university farm to find out the effect of using crude soybean oil sediment (CSOS) as a substitute for refined soybean oil (RSO) in broiler diet. The experiment was carried out following completely randomized design. The chicks were randomly distributed in three treatment gr...
