conjugated linoleic acids (cla) are natural constituents of meat and dairy products from ruminants, originating from bacterial biohydrogenation in the rumen. cla supplementation increases the health benefits of animal-derived foods. there are inconsistent reports of the effects of dietary cla on chicken’s performance; however, the majority of previous reports cite anti-lipogenic effects of cla....

An accurate feed formulation is essential for optimizing feed efficiency and minimizing feed cost for swine and poultry production. Because energy and amino acid (AA) account for the major cost of swine and poultry diets, a precise determination of the availability of energy and AA in feedstuffs is essential for accurate diet formulations. Therefore, the methodology for determining the availabi...

The balance of dietary monovalent electrolytes has been reported to affect many performance-related parameters. When the balance is expressed as Na+K-Cl value in meq per kg of diet, growth rate, eggshell quality, calcification of bone (re: tibia1 dyschondroplasia) and the utilization of arginine in the presence of excess lysine in.poultry is favored by a balance of 200-300 meq per kg of diet. I...

Abstract: Coccidiosis is one of the major parasitic diseases of poultry. In this study, to compare the effects of coccidiostatic drugs on fecal oocyst shedding and body weight gain of coccidi-infected broiler chickens, 180 one day old Ross 308 broiler chicks were randomly assigned to four treatments. Each treatment contained 3 replicates of 15 chickens. Treatments 1 and 2 were fed diets supplem...

The present work was conducted to compare the occurrence of Escherichia coli possessing virulence and ESBL genes in backyard and farmed poultry. Three hundred and sixty samples from the poultry kept in backyard system and 120 samples from the farmed birds were collected from West Bengal, India. Among the E. coli isolates of backyard poultry (O2, O10, O25, O55, O60, O106, UT), none of them posse...

six hundred day old unsexed broiler chicks were used in a 42-d trial at chittagong veterinary and animal sciences university poultry farm to find out the effects of different oils on productive performance of broilers. the chicks were randomly distributed following a completely randomized design in four treatment groups having three replications per treatment. each treatment had 150 birds, with...

a comparative study was conducted with layer hens either intact, or cecectomized or cannulated in the ileum or colon to determine the amino acid digestibility of the same diet. The studies used shaver star Cross 288 layer hybrids, with 6 birds per each test method, in 2 replicates (n=12). Birds were placed in metabolic cages during the studies. nutrient content of the trial diets followed the n...
