This study was conducted on the grazing of West African Dwarf (WAD) goats managed by 41 farmers in Nigeria. The study focused on the use of "fodder banks" by small-scale farmers. The objective of the research was to determine the effect of seeding Stylosanthes hamata on herbage productivity and goat performance under three grazing management systems: tethering (conventional), free grazing natural pasture or free grazing legume-seeded pasture (fodder bank). / Irrespective of the system of management, goats grazing the various pastures had a weaning weight of 6.0 $ pm$ 0.3 kg. At 6, 9 and 12 months the body weights were 9.3 $ pm$ 0.41, 11.7 $ pm$ 1.36 and 12.6 $ pm$ 0.73 kg, resulting from an average daily gain (ADG) of 49.0 $ pm$ 4.0, 33.4 $ pm$ 4.0, 31.0 $ pm$ 0.1 and 25.0 $ pm$ 0.03 g day$ sp{-1}$ for the growth periods of birth to 3 months (pre-weaning) 3-6, 3-9, and 3-12 month (post-weaning) growth periods, respectively. There were no significant differences among the grazing systems with regard to birth weights and 3-month body weight (weaning weight). However, during the 3 to 6-month growth period, the ADG of goats tethered on natural pasture was higher than that observed for goats grazing S. hamata seeded pasture or fenced natural pasture, but this difference disappeared with time. At the 12-month period goats grazing fodder banks were heavier than goats tethered on natural pasture during the late wet season period, but the effect was not significant. Although animals lost weight during the late rainy season, animals grazing fodder banks seemed to have lost less weight than those grazing natural pasture. (Abstract shortened by UMI.)
