Phase-Feeding the Beef Herd for Improved Feed Utilization
Proper nutritional status is critical for optimal production efficiency in the beef cow herd. However, beef producers often take a “one size fits all” approach to feeding the cows in the cow herd. This singular approach to nutrient supply for the cow herd can have serious nutritional and economic ramifications. It should be obvious that not all cows have the same nutrient requirements. Nutritio...
متن کاملThe Utilization of Soybean Products in Tilapia Feed – a Review
Tilapia is one of the most important groups of fish for aquaculture with an annual production exceeds two million metric tons. They have been cultured for quite a long time ago. However, their aquaculture production has been developed remarkably during the last few decades due to the increased level of intensification and cultured area. In the past, fish meal was used as a main protein source i...

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...
Study on nursery growth performance of Pacific white shrimp (Litopenaeus vannamei Boone, 1931) under different feeding levels in zero water exchange system
Effect of different feeding levels on water quality, growth performance, survival rate and body composition of Pacific white shrimp Litopenaeus vannamei post larvae were studied in zero water exchange system. Shrimp post larvae with mean weight of 74.46± 6.17 mg were fed for 32 days in 300L fiberglass tanks containing 130L water at density of 1 post larvae L-1. There were five treatments includ...
متن کاملEffects of varying nursery phase-feeding programs on growth performance of pigs during the nursery and subsequent grow-finish phases
The present study investigated the effects of varying durations of nursery diets differing in percentages of milk products on growth performance of pigs during the nursery phase (NP) and subsequent grow-finish phase (GFP) to find the feasibility of reducing the use of nursery diets containing costly milk products. A total of 204 21-d-old weanling female and castrated male pigs were subjected to...
