Effects of Levels of Ficus (Ficus sycomorus) Supplementation on Voluntary Feed Intake, Nutrient Digestibility and Nitrogen Balance in Yankasa Bucks Fed Urea Treated Maize Stover Basal Diet


Department of Animal Science, Ahmadu Bello University, Zaria, Nigeria


The study was conducted to evaluate the effects of feeding varying levels of Ficus sycomorus leaf forages as protein supplements to a basal diet of urea treated maize stover. Four Yankasa goats averaging one year and weighing 11.7±1.8 kg were used to measure the feed intake, digestibility and nitrogen balance. The basal diet (urea treated maize stover) was supplemented with 0 (T1), 50 (T2), 100 (T3) or and 150 (T4) g of fresh F. sycomorus leaves. The intake of the basal diet was significantly (P<0.05) affected by supplementation with browse foliage. T3 had significantly P, and 25.01 g/d for T1, T2, T3 and T4, respectively. Evaluation of Nitrogen retention as a percentage of intake followed a similar pattern. F. sycomorus has potential as a protein supplement and could be offered at 100g/day in growing goats fed urea treated low quality basal diets.
