육성 비육돈에 대한 동 에너지 수준에 계절별 우지 첨가 효과 = Effect of Dietary Tallow Supplementation with Constant Energy Level During Summer and Winter for Growing - Finishing Swine

다국어 초록 (Multilingual Abstract)

A trial with one-hundred-forty-four crossbred pigs were conducted to study effects of dietary tallow supplementation (0, 2, 4, 6, 8 and 10% tallow) with constant energy level (3,400 ㎉ P.E. per ㎏ feed) during summer and winter on the performance and carcass characteristics of growing-finishing swine. Seasons had no significant influence on average daily gain, feed intake, feed per ㎏ gain and carcass traits. In winter, daily gain, feed intake and feed per ㎏ gain were reduced with increasing level of tallow addition, whereas dressing percentage and backfat thickness were increased with increasing levels of tallow supplementation. In summer, daily gain, feed intake and feed per ㎏ gain responded quadratically as levels of tallow addition increased, yet dressing percentage and backfat thickness were increased as levels of tallow supplementation. It was estimated that the optimum level of tallow in a diet with 3,400 ㎉ D.E. per ㎏ feed for growing-finishing swine in summer season was 4%.
