摘要
Twelve adult (10 months old) castrated Korean black goats, with an average initial body weight of 24.98 ± 3.7 kg, were used in this experiment to determine their maintenance energy requirements. Dry matter intakes (g/d, p = 0.945) were not affected by energy levels, but metabolic energy intake (kcal/d, p < 0.002) and average daily gain (g/d, p < 0.001) were significantly increased at higher energy levels. Nutrient digestibility was similar in the treatments, but crude fat digestibility increased with the addition of protective fat powder (p = 0.001). The energy required for fattening the castrated Korean black goats was estimated using the correlation between metabolic energy intake per dietary body weight and average daily gain per dietary body weight. The Y-axis intercept value was calculated to be 108.76 kcal/kg BW0.75 (p < 0.05, r2 = 0.6036), which was the metabolic energy requirement for maintaining the lives of the fattening Korean black goats. The estimated energy requirements of the black goat can improve specification techniques, such as the energy level and the amount of feed supply required for domestic black goats.

12位成人（10个月大）阉割韩国黑山羊，平均初始体重为24.98±3.7千克，在本实验中使用，以确定其维护能源要求。干物质进气（G / D，P = 0.945）不受能量水平的影响，但代谢能量摄入量（KCAL / D，P <0.002）和平均每日增益（G / D，P <0.001）在较高程度上显着增加能量水平。在处理中营养消化率相似，但是通过添加保护脂肪粉（P = 0.001）增加粗脂肪消化率。使用每种膳食体重的代谢能量之间的相关性和每次膳食体重平均每日增益来估计肥胖阉割韩国黑山羊所需的能量。 Y轴截距值计算为108.76 kcal / kg bw0.75（p <0.05，r2 = 0.6036），这是维持零下山羊的生命的代谢能源要求。黑山羊的估计能量要求可以改善规格技术，例如能量水平和国内黑山羊所需的饲料供应量。
