Three experiments were conducted to evaluate the order of limitation for Lys, Thr, and Val in corn-soybean meal diets of lactating sows experiencing high BW loss during lactation. Plasma urea N (PUN) was used as the response criterion. Experimental diets used in all 3 experiments were derived from the basal diet (BSL) formulated to 0.51% Lys using corn and soybean meal as the only sources of AA...

this study was conducted because of influence of prebiotics (alphamune) and symbiotic (biomin) on histometrical development of small intestine and lymphatic tissue of caecal tonsil have been not reported on broiler chicken. in this study, different parts of small intestine and caecal tonsil, which is a major area of gut associated lymphatic tissue (galt) in chicken were selected. one hundred an...

The purpose of this study was to evaluate the effect of creatine supplementation in the diet on indicators of glucose metabolism in skeletal muscle of exercised rats. Forty Wistar adult rats were distributed into four groups for eight weeks: 1) Control: sedentary rats that received balanced diet; 2) Creatine control: sedentary rats that received supplementation of 2% creatine in the balanced di...

this experiment was conducted to investigate the effects of using three commercial enzymes on performance and carcass quality of broiler chickens fed with wheat-barley-soy based diets. in a completely randomized design 405 of broiler (ross308) in nine treatments, three replicates (with 15 bird in each replicate) were used. the experimental diets included 1) diet based on corn–soybean meal (with...

A high-sucrose diet (SU) decreases insulin action in the liver (Pagliassotti MJ, Shahrokhi KA, and Moscarello M. Am J Physiol Regulatory Integrative Comp Physiol 266: R1637-R1644, 1994). The present study was conducted to characterize the effect of SU on glucagon action in isolated periportal (PP) and perivenous (PV) hepatocytes by measuring glucagon-stimulated glycogenolysis and glucose releas...

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 study was conducted on 72 day old straight run commercial broiler chicks (DOC) till 6 weeks of age to investigate the effect of Tulsi (Ocimum sanctum) leaf powder (TLP) on the hematological parameters of broilers. Chicks were randomly divided into four groups of 18 chicks each. Control group received standard broilers diet. Chicks in second, third and fourth group received standard broilers...

Commercial White Leghorn hens (65, 63, or 70 wk of age in Experiments 1, 2, and 3, respectively) were induced molted by feed withdrawal until approximately 28% body weight was lost. All hens were then weighed, and seven replicate groups of 12 hens each were fed molt diets. In Experiment 1, three diets consisted of a corn basal diet (7.9% CP) or this diet supplemented with corn gluten meal (CGM)...

We conducted 2 consecutive experiments to verify whether adult captive Greater rheas (Rhea americana) could select diets differing in nutritional and energetic content, and to evaluate the effect of those diets on egg production and hatchability. From August to January, animals were offered four diets: processed feed for rheas (diet 1), diet 1 + soybean (diet 2), processed feed for chicken (die...
