ABSTRACT

Aim:The objectives of this study was to evaluate the effects of substituting barley with wet sugar beet pulp silage prepared with mixing 8% wheat bran at differing levels on feed intake, digestibility, total crude protein (CP) entering into duodenum and some protein fractions and some rumen fermentation parameters.

Material and Method:To achieve this objective, four isocaloric and iso- nitrogenous diets were prepared by substituting barley energy with wet sugar beet pulp silage (WSBPS) at 0% (control), 30% (30% WSBPS), 70% (70% WSBPS) and 100% (100% WSBPS). These diets were fed to 4 ruminally and duodenually cannulated Kıvırcık x Morkaraman crossbred lambs within 4x4 Latin Square design. Experiment was carried out as 4 periods consisting of 16 days after 20 days of adaptation period.

Daily dry matter intake, total DM, OM and CP digestibilities were highest in sheep fed 70% WSBPS and lowest in sheep fed 100% WSBPS (P>0.05). The highest and lowest amount of total DM, OM and CP digested were 1157.15-920.71; 1098.61-868.02 and 161.74-114.49 g/d, respectively (P>0.05). The highest NDF and ADF digestibilities were observed with 70% WSBPS, the lowest NDF and ADF digestibilities were observed with control group. Total crude protein (CP) entering into duodenum (130.09 g/d) and microbial HP(101.60 g/d) were the highest in sheep fed 70% WSBPS and total crude protein (CP) entering into duodenum (104.14 g/d) and microbial CP (81.91 g/d) were lowest in sheep fed 30% WSBPS.

Results:In conclusion, it can be concluded that energy coming from barley can be substituted with wet sugar beet pulp silage prepared with mixing wheat bran up to 70% and can even be substituted with wet sugar beet pulp silage prepared with mixing wheat bran up to 100% if some production loss is neglected.
