This experiment was conducted to evaluate the effects of supplemental L-arginine (ARG) in reduced-protein diets on cardiopulmonary performance and intestinal morphology in the broilers reared at high altitude. A total of 156 day-old male broilers were randomly assigned to 3 treatments and 4 replicates of 13 chicks and reared up to 42 days of age. Treatment groups were designed as a normal-prote...

the aim of this study was to evaluate the biochemic combination of giant sturgeon (huso huso) juveniles carcass which fed with gingar (zingiber officinale) extract. fish with average initial weight 15 + 0.8 g fed 0.5% and 1%  of gingar hydroalcohol extract for 8 weeks. samples were gathered in the final of experimental period and the fatty acids were determined by gas chromatography. results sh...

early weanling and rearing of lambs on milk replacer is an important act to increasing flock productivity. two experiments were carried out to compare the voluntary intake and nutrients digestibility ewe milk and commercial milk replacer and their feeding effects on the growth rate, feed intake and feed efficiency of suckling lambs. in experiment 1, eight lambs (two 4-lamb groups) at 31 to 34 d...

in a 42-d experiment, 576 one-day-old vencobb 308 broiler chicks were used to investigate the effects of lecithin extract (0.5 g/kg), choline chloride 60% (1 g/kg) and bio choline (1 g/kg) in diets of moderate and high energy in a 4 × 2 factorial arrangement on performance and certain physiological traits in broiler chickens. the inclusion of bio choline and lecithin extract in the diet signifi...

Grass feeding is a practice not yet familiar to all consumers. 100% grass-fed cow's milk comes from cows who have grazed in pasture year-round rather than being fed a processed diet for much of their life. Grass feeding improves the quality of cow's milk, and makes the milk richer in omega-3 fats, vitamin E, beta-carotene, and CLA (a beneficial fatty acid named conjugated linoleic acid). (For m...
