the study was carried out on 120 crossbred holstein × shahiwal dairy cows for a period of 150 days to quantify the influence of dietary energy and protein intake on yield and composition of milk. total 12 dairy farms having similar housing systems and holding at least 20 dairy cows in between mid to late lactation were selected for study purposes. the farms were located in the peri-urban and ur...

In this study, Effects of garlic (Allium sativum) extract on growth indices and hemolymph parameters of Litopenaeus vannamei with mean weight 18.21±0.29 g were studied for a period of 56 days. This study was conducted inside 300-liter polyethylene containers as four treatments each with four replicates and each replicate testing 5 shrimps. A basic diet supplemented by 0 (control), 40, 80 and 10...

Background: Proteins are known mainly based on their metabolic and nutritional functions including protein synthesis and a source of energy. In spite of various physiological properties attributed to proteins, their functions have neither been addressed by assessing quality of proteins nor by nutrition and dietetic practices. Methods: Studies were included if they were randomized animal studies...

this experiment was conducted to determine the effect of using l-threonine and reducing dietary levels of crude protein (cp) on egg production criteria in layers. three hundred of hy-line w36 laying hens were used in this experiment. this experiment consisted of three experimental treatments with five replications in each. experimental treatments included 3 diets with different levels of cp whi...

Growth performance, carcass composition, and immunophysiological indices in juvenile great sturgeon (Huso huso) fed on commercial prebiotic Immunoster (IS) were investigated. After a four-week acclimatization period, 270 great sturgeon juveniles weighing 95.68 ± 10.05 g were randomly distributed into 9 fiberglass tanks in three replicates and kept at a density of 30 fish per tank for a period o...
