Abstract
Sixteen Black Bengal goats (10–12 months of age) were divided into 4 equal groups and fed 1 cm (T1), 2 cm (T2), 3 cm (T3) and 4 cm (T4) long paddy straw ad libitum along with 90 g ground nut cake for a period of 90 days. Daily dry matter intake was similar in all the groups. The digestibilities of crude protein, cell wall content and ether extract showed some effect of treatments. The goats exhibited positive nitrogen balance and negative calcium and phosphorus balances irrespective of treatment.
