ABSTRACT

A study was conducted to evaluate the effect of inclusion level and feeding regime of Ficus sycomorus leaf meal on the growth performance of Yankasa rams. A total of 36 rams weighing on the average 15.39kg were randomly assigned to four diets, containing 0, 5, 10, and 15% inclusion level of Ficus sycomorus, respectively. Each of the animals was fed 2% body weight of the experimental diet in three feeding regimes: daily, skip-a-day and skip-2-days in a 4x3 factorial arrangement in a completely randomized design. The effect of F. sycomorus supplementation on nutrient digestibility and nitrogen balance revealed that dry matter (DM), organic matter (OM) and crude protein (CP) digestibility were significantly (P<0.05) affected by the inclusion level. Nitrogen (N) retention and N retention as percent intake were affected significantly (P<0.05). Percent DM, OM and CP digestibility were influenced (P<0.05) by feeding regime, with daily feeding recording higher values (67.80, 63.05 and 62.23 respectively) when compared to skip-a-day and skip-2-days. It was concluded that the inclusion of Ficus sycomorus leaf meal in the diet of growing rams did not perform more than the control diet and also, daily feeding regime was better in nutrient digestibility, nitrogen intake and nitrogen retention.

SUMMARY:

The increase in nitrogen intake as inclusion level and feeding regime reduces from daily feeding to skip-2-days is similar to the findings of Soto-Novarro et al., (2000), who reported an increased in nitrogen intake of feed offered to steers as treatment x feeding frequency interacted.
