Abstract: In this study, a fattening experiment was carried out under the confined condition to evaluate the feeding effect of different ecological feed formulations on new breed of black goat, and the breeding economic benefit was also analyzed. The results showed that except E group, there were significant differences in daily weight gain between CK and the other experimental groups; the highest and lowest daily weight gain were observed in C group（246.32 g per goat） and CK（186.24 g per goat）,respectively, and the daily weight gain of C group was 60.08 g per goat higher than that of CK, indicating the increasing range of32.20%; compared with the CK, the daily weight gain of A, B, D and E groups were also increased by 20.01%, 10.13%, 12.09%and 2.15%, respectively. The highest total feed intake was observed in E group（2 951.65 kg） and the lowest was found in A group（1 339.50 kg）; the highest average daily feed intake was observed in E group（3.28 kg per day per goat） and the lowest was found in A group（1.49 kg per day per goat）. In terms of fattening economic benefit, C group exhibited the best performance and its economic benefit was increased by 72.67% compared to CK. In conclusion, the formulation C is demonstrated to be more suitable for the modern ecological breeding of goats and has wide application prospects.
