Comparative evaluation of maize bran, wheat bran and rice bran on milk production of holstein friesian cattle

The present study was designed to compare the efficiency of comparative evaluation of cereal by-products. A total of twelve animals were selected from dairy herd. The selection was done on the basis of age, body size, lactation number and breed. The animals were randomly divided into three groups i.e. A, B and C. Comprising four animals in each group. Group A was given maize bran; group B wheat bran and group C was given deoiled rice bran. The milk production was recorded daily while butter fat, total solids and solids-not-fat were recorded twice a week. The data collected was subjected to statistical analysis using two-way analysis o f variance and least significant difference (LSD) test, to detect the differences between the treatments and means. It was concluded that maize bran as a feed ingredient revealed significant (P less than 0.05) difference regarding milk production among the groups. While rice bran proved to be the most economical ration among the other ingredients. The results of wheat bran and rice bran due to economics, milk production and milk composition were not satisfactory. The Holstein-Friesian cows in group-A yielded average 18.05 plus minus 3.60kg milk. While in group-B yielded 2.87 plus minus 1.10kg milk and cows in-group C yielded 14.65 plus minus 1.11 kg milk. The Analysis of variance of milk yield revealed a significant difference (P less than 10.05 among different groups. Group-A yielded higher daily milk fat as compared to other groups, while group-C yielded higher milk fat as compared to group-B. The Holstein-Friesian cows in group- A yielded 3.509 plus minus 0.148 % butter fat. While in group-B yielded 3.591 plus minus 0.068 % butterfat and cows in group-C yielded 3.606 plus minus 0.089 butterfat. The cows fed on wheat bran based diet yielded a higher fat percentage followed by cows fed on rice bran. The cows fed on maize bran based diet produced lowest fat. The analysis of variance of butterfat revealed a non-significant difference among different groups. Group-C yielded higher butter fat as compare to the other groups, while group B yielded higher butterfat than the group-A. The Holstein- Friesian cows in group-A given yielded 12.268 plus minus 0.181 % total solids of milk. While in group-B yielded 12.386 plus minus 0.090 % milk and cows in group-C yielded 12.372 plus minus 0.111 % total solids. The analysis of variance of total solids of milk yield revealed non-significant difference among different groups. Group-B yielded higher total solids of milk (12.386 plus minus 0.090) as compare to the other groups while group C yielded more percentage compare to the group-A. The Holstein-Friesian cows in group-A yielded 8.720 plus minus 0.0.25 % solids-not-fat of milk. While in group-B yielded 8.706 plus minus 0.031 % solids not fat and cows in group-C yielded 8.774 plus minus 0.009 % solids not fat. The analysis of variance of solids-not-fat of milk yield r e vealed a non-significant difference among different groups. Group-C yielded higher solids-not-fat percentage of milk (8.774 plus minus 0.009 %) as compared to the other groups, while group-A yielded more percentage of solids-not-fat compare to the group-B. Milk production economics per cow figures were higher (Rs.68.03) in group-A followed by group-C (Rs.31.62) and group-B. It may be concluded that the ration based on maize bran was more efficient and economical than other rations based on inclusion of rice bran and wheat bran.
