선형계획에 의한 배합사료가 Broiler 에 대한 경제적 영양소요구량에 관한 연구
이영철,하서현 ( Young Chul Rhee,Su Hyun Ha ) 한국축산학회 1976 한국축산학회지 Vol.18 No.5
This experiment was conducted to seek the economic nutrient requirements of practical broiler diet under the circumstances of Korea where high energy ingreidents are scarcely available. Four different least cost diet were formulated using electric computer to contain 3200 ㎉ ME ㎉ per ㎏, 3000 ㎉, 2800 ㎉ and 2600 ㎉ respectively and 2600 ㎉ respectively and other required nutrient equivalent to each ME content. The grass income was the highest for lowest energy diet showing 419 won, 411 won, 382 won and 388 won respectively. This was accomplished by significantly lowered feed cost per ㎏ as the ME content of experimental diet lowered. Although they showed decreased body weight gains and greatly increased feed intakes. This results implies that highest nutrient requirements as showing NRC are not always return highest profit as long as the situations like this experiment are concerned.
