dc.description.abstractSeasonal factors affect the availability and nutritive value of groundnut haulms. Hence some farmers prefer early-maturing varieties while others prefer late-maturing varieties. This study determined the effects of bale temperature on spontaneous heating of groundnut haulm bales, digestibility and growth performance of sheep fed early- or late- maturing varieties of groundnut haulms. Early-maturing varieties (90 days) included Chinese, Yenyawoso and Sumnut 23 whereas late-maturing varieties (110−120 days) were Sumnut 22, Azivivi and Manipinta. Split plot design was employed to cultivate each variety on 4 different replicate plots of 2.4 × 4.0 m2 , 3.6 × 4.0 m2 , 4.8 × 4.0 m2 and 6.0 × 4.0 m2 . At maturity, all the varieties were harvested. The pods were separated from the haulms (leaves and twigs) and equal portions of the haulms were combined into early- or late-maturing varieties. In experiment I, the groundnut haulms were baled and shade dried. During the shade drying, core bale temperatures and room temperatures were recorded at the same hour (3:03:00 PM) Greenwich Mean Time (GMT) in the consecutive days as it was done for the first day. Each of the combined haulms were then dried to a DM of 92% and chopped to a theoretical length of 3–4 cm before being used to formulate two diets that were fed to West African Dwarf growing rams (14.75 ± 2.52 kg) every morning (07:00 am GMT) and every evening (05:00pm GMT). in experiment II. In experiment III, two fistulated Nungua Black Head sheep were used to determine the in situ digestibility of early- or late- maturing groundnut haulms. The concentrations of ADF and ADL were greater (P < 0.05) in the early- compared to late- maturing haulms whereas the extent of digestibility of the late-maturing varieties was higher than the early maturing variety. The intake and growth performance of sheep did not however differ (P = 0.69). This study suggests that duration to maturity has no effect on the nutrient quality of groundnut haulms and on the growth performance of sheep.en_US
