摘要
This study was conducted to determine the energy requirements for maintenance of growing Korean native goats (black goat: Capra hircus coreanae). The experiment had a replicated 5×5 Latin square design, using five growing wethers [24.13±2.55 kg body weight (BW)]. Each wethers was individually housed in a metabolic cage and first given 10 days for diet adaptation prior to 7 days of experimental measurements. The goats received timothy (12%), tall fescue (28%), cornflake (30%), concentrates (20%) and one of the following five energy level treatments that were based on recommended metabolizable energy for maintenance, Mem (NRC, 2007): MEm-7% (trial 1), MEm (trial 2), MEm+10% (trial 3), MEm+20% (trial 4), MEm+30% (trial 5). Intakes of dry matter were similar across all diets by restricting feed supply at 2% of BW for all wethers. Average daily gains (ADG) were -14.22, 3.06, 18.06, 31.62, and 37.16 g/day for each treatment. Higher maintenance energy intake (MEI) led to higher ADG. By simple regression analysis, the following equation was defined between ADG and MEI: Y(MEI)=0.2735X(ADG)+112.19. The findings indicate that the estimated maintenance energy requirement for growing black goats is 112.19 kcal/kgBW0.75. The estimated value of MEm can be further managed and improved with precision feeding system for black goats.

进行该研究以确定维持生长的韩国本地山羊（黑山羊：Capra hircus coreanae）的能量需求。该实验重复了5×5拉丁方设计，使用5个生长母亲[24.13±2.55kg体重（BW）]。每个糖亲自单独饲养在代谢笼中，并且在实验测量7天之前首先给予10天饮食适应。山羊接受了蒂莫西（12％），高羊茅（28％），Mem（NRC，2007）：MEm-7％（试验1），玉米片（30％），浓缩物（20％）和以下五种能量水平处理之一，MEm（试验2），MEm + 10％（试验3），MEm + 20％（试验4），MEm + 30％（试验5）。干物质的摄入量在所有日粮中都相似，限制所有奶制品的饲料供应为体重的2％。每次治疗的平均每日收益（ADG）分别为-14.22，3.06，18.06，31.62和37.16克/天。更高的维持能量摄入（MEI）导致更高的ADG。通过简单的回归分析，在ADG和MEI之间定义下列等式：Y（MEI）\x3d 0.2735X（ADG）+112.19。调查结果表明，生长黑山羊的维持能量需求估计为112。19千卡/千克Bw 0.75 / sup。黑山羊精饲养系统可以进一步管理和改进MEm的估计值。
