Abstract

Dry layer litter (DLL) was used to substitute ~ottonseed 'cake (CSC) in intensive ram fattening study in attempt to reduce the cost of production. Twenty four (2.4) Yankasa rams· aged 24-30 months and weighing 33.0±3.0 kg were· assigned to 4 treatments in, a completely ,randomized design, --6 -rams --by treatment and- individually fed. The concentrate :was offered at 1.0, 1:5, 2.0 and 2.5 % of body weight (BWT) respectively followed by chopped maize stover-at 2;0' % of BWT across the treatinents;i Water. was provided ad libitum throughmit the study peri0d of 112 days. Digestibility trial was conducted during the last·14 days of fattening ·study. Rams were weighed weekly and the weights were used to adjust the· level of feeding ·accordingly to- reflect percent of BWT. Weight changes were recorded separately for each ram; Gross margin analyses were done to determine feed cost per gain, value of gain and income over feed cost. All data were subjected to statistical analysis using the GLM of SAS (1998). Results indicated the ADG to be 73:84, 101.87, 140.18. and.137.68 g/head/day at 1.0, J.5, 2.0 and 2.5 % of B.WT. feeding of the concentrate respectively'. There-were- no significant . differences .(p>0.05) between 2:0 and 2.5% levels of concentrate feeding; Dry·niatter and CP digestibility were significantly_ different (p<0.05},between the control and 2.5 % level. Crude fibre digestibility decreased.with increased level of :feeding.-.Gross margin analysis showed that there was,no •1>ignificant·differeilce (p>0.05} in_feed cost-per gain between 1.0 % and 1.5. % levels. Feed cost "per gain was significantly lowest at 2.0 % level:· There was no significant difference· (P>0;05)' in value· of' gain -between rams fed the concentrate at 2.0 % and those fed- at 2.5 % of BWT. Income over feed cost was significantly highest (p<0.05) at 2.0 % level of concentrate feeding. It can be concluded that. feeding rations ·in ·which DLL. replaced CSC tO" 'fatten rams at -2.0 % of BWT resulted· in the best performance and the highest income over feed· cost.
