摘要

A total of 12 male sheep with an average BW of 19±2 kg were used in this experiment to assess the effectsof frequency of supplementary concentrate on digestion, rumen fermentation and voluntary feed intake ofgroundnut haulms. The supplementary concentrate (100 g/day) was offered once (1×), divided into two equalportion offered twice (2×) or divided into three equal portion offered three times daily (3×). The dry matterintake (DMI), digestible dry matter intake and crude protein intake (CPI) of groundnut haulms showed nosignificant difference if concentrated supplement were offered once (1×), twice (2×) or three times (3×) a day.The digestibility values for DM, CP and NDF were not responding to the feeding frequencies of concentratedsupplement. The total nitrogen intake, urinary nitrogen and nitrogen retention were similar among thefrequencies, however, fecal nitrogen was significantly (P< 0.05) different when the concentrated supplementoffered 1× than 2× or 3× a day. The ruminal NH3-N was significantly (P<0.05) higher when the concentratedsupplement offered 1× than 2× or 3× a day. As a conclusion, sheep maintained on groundnut haulms (10.3%CP) were not responding to a concentrated supplement if offered once (1×), twice (2×) or three times (3×) a daydue to a sufficient amount of crude protein in the basal diet.
