摘要：

Energy requirements for maintenance and gain of West African Dwarf (WAD) goats were studied in two experiments, in which 24 animals were divided into four groups of six animals each. The treatments included hay (in most cases ad lib.) plus varying amounts of pelleted concentrates, causing intake of digestible organic matter (IDOM) to vary from 28.3 to 56.6 g kg-0.75 d-1 and live weight gain (LWG) from 2.1 to 13.1 g kg-0.75 d-1. The two variables were related as follows: LWG = -10.1 + 0.415 IDOM. Based on this equation, maintenance requirements of WAD goats are estimated at 24.3 g DOM (384 kJ ME) kg-0.75 d-1 and requirements for LWG at 2.41 g DOM (38.1 kJ ME) g-1. A critical review of the literature shows that the large variation in earlier estimates of energy requirements of goats is partly due to differences in experimental design and methods of data analysis. Mean values of LWG and IDOM from earlier studies can be applied to the same equation as the above. However, the RSD is higher, indicating deviations due to type of animal, environment and/or quality of feeds.
