this experiment was conducted to investigate the effect of synbiotic and two levels of dried garlic powder on performance during 1-49 and ileum morphology and microbial population at 49d of age in broiler chicks. the experiment was conducted in a completely randomized design with 5 treatments, 4 replicates of 10 chicks per replicate. the dietary treatments consisted of 1) control diet without a...

Objective(s) In addition to antihypertensive effects, amlodipine may exhibit cardiovascular protective effects in heart tissue. The aim of this study was to evaluate the effects of amlodipine and/or high cholesterol diet on blood, heart tissue concentration and mRNA expression of endothelin-1 (ET-1) in male New Zealand white rabbits. Materials and Methods A total of 40 male New Zealand rabbi...

four ruminally-cannulated holstein cows were used in a 4 × 4 latin square changeover design within periods of 21 days to evaluate effects of feeding frequency of different sources of rumen degradable nitrogen on total tract digestibility of nutrients, feeding behaviors, rumen and blood metabolites of holstein cows. treatments were: 1) control diet which was as total mixed ration (tmr) offered o...

this study was conducted to evaluate the effect of supplementing diets of milking cows monensin supplementation alone or in combination with methafix (a commercial product containing malate and fumarate) on nutrient digestibility, milk production and composition and milk fatty acids profile. using four multiparous holstein milking cows (657± 12 kg of live weight; 133 ± 41days in milk) in a lati...

The present study was conducted to investigate the effects of dietary energy sourcesandlevels on performance and small intestinal morphology in broiler chickens. A total of 600 one-day-old broiler chicks were randomly divided into five treatments with four replicates each. Chicks were fed diet based on corn as main energy source and energy level based on Cobb 500 manual instruction considered c...

this trial was conducted to investigate the effect of phospholipid on blood and serum factors in rainbow trout (oncorhynchus mykiss) fed fat powder. phospholipid in two levels was added to 20 percent fat based on diet including 50% fat powder. control diet contained fish oil instead of fat powder and was lack of phospholipid. 150 juvenile rainbow trout with initial mean weight of 27.45±1.88g st...

a total of 528 day-old ross 308 male broilers were used to study the effect of antibiotic, probiotic, prebiotic and organic acid on performance, cecal coliform load and internal organs’ weight. the chickens were placed into 6 groups with 4 replicates and 22 chickens per pen. six dietary treatments included: 1) negative control as basal diet without any antibiotic growth promoter and coccidiosta...

Background & Aim: This experiment was conducted to examine the effect of different levels of Echinacea purpurea (EP) in comparison with an antibiotic (flavofosfolipol) on total antioxidant activity (AOA) in serum of broiler chicks. Experimental: In this trial 240 one-day-old broiler chicks (Ross 308) were weighed and randomly assigned to the 5 treatment groups, each with 4 re...
