Abstract
Objective: To obtain a guideline of supplementation with concentrated feed on production efficiency, feed intake and hematology value in beef cattle
Materials and methods: A Completely Randomized Design (CRD) was used in which 30 animals were fed. All cows were given rice straw as a roughage source. The concentrated feed was added to fermented cassava residue with usable energy and protein based on body weight at 1.5% BW as follows: 1) concentrate 16% CP: supplemented fermented cassava residue (100: 0) 2) concentrate 16% CP: supplemented fermented cassava residue (50:50) 3) concentrate 16% CP: supplemented fermented cassava residue (30:70). Data of changes in body weight, feed intake, hematology values were collected and analyzed data by software packages (SAS, 1996).
Results: The results of the study showed that ADG, FCR were not statistically different (P> 0.05) among the three treatments fed beef cows. While, Total DM intake, rice straw intake, concentrate intake in term of kg, g kg-1BW0.75 was highest in beef cattle fed with concentrate 16% CP: supplemented fermented cassava residue (30:70) but Total DM intake, rice straw intake, concentrate intake in term of %BW was no statistically difference (P> 0.05). In addition, the four treatment fed beef cattle did not differ statistically for BUN and Hct (P> 0.05).
Conclusion: This study concluded that feeding concentrate 16% CP: supplemented fermented cassava residue (30:70) resulted in an increase in the amount of intake and supplementation with the concentrated diet had no effect on production efficiency and hematology value
Keywords: Beef cattle, production performance, hematology
