the hypothesis of this experiment was that the various sources of dietary fat with different dietary ratios of polyunsaturated fatty acids (pufas) to saturated fatty acids (sfas) would alter the reproduction parameters of mature rams. twelve mature rams were randomly allotted to one of four dietary treatments in a completely randomized design. dietary treatments were: 1) ration with 4% soybean ...

the aim of this study was to evaluate the effects of balancing low protein diets for methionine and lysine on performance of early lactation holstein cows under hot environmental temperature. twenty one multiparous holstein cows in early lactation were allocated to three experimental rations including, 1) high protein ration with 17.5% cp, 2) medium protein ration with 16% cp and 12 g/d rumen p...

the present study was carried out to evaluate the effects of dietary nano-structured zeolite (nz) levels on reduction of aflatoxin b1 (afb1) in the diet of rainbow trout (oncorhynchus mykiss) for 56 days. for this purpose, 270 fish (23 ± 3.7 g) were randomly distributed into 6 groups including c (control), nz0.5 (basic ration + 0.5 % nano-structure zeolite), nz1 (basic ration + 1 % nano-structu...

Veterinarians increasingly play a major contributory role in dairy practice and management. Withincreasing importance of economical pressures, bioenvironmental limits and increasing demand for higherquality products, veterinarians are more involved in nutrition management and advice, both from aneconomical view of productivity and preventive aspects of veterinary medicine. The concept of food a...

AIM The aim was to investigate the effects of dietary supplementations of prebiotic, probiotic, and synbiotic on growth performance and carcass characteristics of broiler chickens. MATERIALS AND METHODS A total of 360 1-day-old Vencobb broiler chickens of either sex were randomly assigned to four dietary treatments each consisting of three replicates and each replicate having 30 birds for 6 w...
