Comparative study several feed formulation based on agro-industrial by-product on production performance and in vivo digestibility of beef cattle

Abstract

The aims of this study was to determine the effect of agro-industrial by-products on the production performance and digestibility of nutrient of beef cattle with four feed formulations. The treatments such as F1, F2, F3 and F4. The material used was 28 cows with an initial weight in the range of 380.11 ± 13.69 kg with Simental and Limousine crossbreeds; beef cattle faeces samples were 112 samples from 4 feed treatments and 7 replications. The variables observed were production performance of beef cattle and digistibility of nutrient. The results of the study shows that the use of agricultural by-products has a significant effect on dry matter intake (P <0.05). (10.20 ± 0.43 kg/head/day), dry matter digestibility (75.48 ± 1.46%) and no significantly effect (P>0.05) on organic matter intake, crude protein intake, crude fibre intake, increasing of daily body weight, feed conversion ratio, feed efficiency, feed cost per gain, income over feed cost, digestibility of organic matter, digestibility of crude protein, and digestibility of crude fibre. The conclusion of this study was F3 had the best treatment to increase feed intake, digestibility of dry, digestibility of organic matter, digestibility of crude protein, crude fibre digestibility of beef cattle.
