dc.description.abstract This study was conducted in Kordofan region western Sudan to evaluate agronomic, phenological and nutritional value of three forage legumes Cajanus cajan (pigeon pea), Clitora ternatea (clitoria) and Vigna ungiculata (cow pea). The agronomic experiments were conducted at two different locations, loamy soil (North Kordofan) and dark cracking clay soil (South Kordofan) under rainfed conditions in 1994. The agrophenological characteristics were days to germination and days to 50% germination, days to flowering and days to 50% flowering, days to pod formation and days to 50% pods formation and days to harvest as well as plant height, number of leaves and number of pods per plant, number of seeds per pod, hundred seed weight, fresh and dry matter forage yields. The forage legume were dried into hay, crushed and mixed together at a ratio of 5: 3: 2 cow pea, pigeon pea and clitoria, respectively and were used as a supplement to dairy goats during the dry season. Both plant species and location significantly (P<0.01) affected most of the agrophenological parameters. The cow pea showed the best agrophenological characteristics compared to the other two legumes. With respect to location, plants grown in loamy soil (Khor Abied) had better agrophenological characteristics than those grown in dark cracking soil (Angarko). In terms of chemical composition, the nutritive value of cow pea was better than pigeon pea and clitoria, although the crude protein (CP) contents were nearly similar. The neutral detergent fibre (NDF) and acid detergent fibre (ADF) were negatively correlated with in vitro dry matter digestibility (IVDMD) and in vitro organic matter digestibility (IVOMD). In this respect cow pea showed the highest (P<0.01) digestibilities followed by pigeon pea and clitoria. In general, plants grown on loamy soil had better (P<0.05) chemical composition and digestibilities than those on dark cracking soil. Ten desert dairy goats were randomly allocated in a completely randomized block design. They were divided into two equal groups. One group was given the supplement legume hay mixture and the other (control) was allowed to graze around. Although the chemical composition of the supplement was better than the grazed pasture, no significant changes were observed in body weight gain or milk yield. However, phosphorous plasma levels were significantly (P<0.05) higher in the supplement group. In conclusion legume forage can provide an excellent supplement for livestock during the dry season, when pasture forages are of very low quality. en_US
