"부로일러" 飼料에 있어 油脂 添加에 對한 飼養試驗과 經濟性 分析에 關한 硏究 : 同熱量 水準의 飼料에서 on an Isocaloric basis
吳世正,金春洙,權恒基 건국대학교 1971 學術誌 Vol.12 No.1
The usage of tallow to replace corn on an isocaloric basis upto 9 percent level did not improve the growth over the control chicks and no significant difference was. also observed in the feed efficiency of control group from those of the experimental groups of receiving 3,6 and 9 percent tallow. This is also true for the values of among the experimental groups. Through the observations of these results. it is concluded that tallow as a feed ingredient can be added to the diet upto 9 percent level on an isocaloric basic, without deteriorating it's untritive value. With an estimated price of tallow 70 won per kg. weight, the addition of tallow for the place of corn on an isocaloric basis resulted in higher prices of the feeds of added tallow. Since no improvement on the feed efficiency was affected by the addition tallow, it is assumed that the economy of broiler production is very much depended upon the cost of tallow rather than the value of tallow itself. Based on the current market price of corn 25.28 won per kg. weight, it is estimated that tallow as a feed ingredient is to bepriced at less than 65.73 won per kg. weight to bring about broiller production cost economically possible.
