EFFECT OF CONCENTRATE ON MILK PRODUCTION, MILK FAT AND BODY WEIGHT CHANGES OF INDIGENOUS COWS RAISED IN CHAR AREA

Abstract

This study was conducted to know the effect of concentrate on milk production, body weight changes, milk fat of indigenous cows under char condition. This experiment was performed in parbotipur at Zatrapur union in Kurigram Sadar Thana. The experimental duration was three month (April to June). Eight cows were selected on the basis of body weight, milk yield and lactating phase (in second lactation). All the animals were dewormed and vaccinated at initial stage. The animals were divided into two group .The animals of one group (T1) offered concentrate mixture and other group (T2) group offered only traditional diet. The milk production of cows recorded daily. The body weight of cows measured every after 30 days. Milk samples was collected every after fifteen days to test the fat content of the milk. Initially the milk production of the animals were near about 1kg per day. During the study milk production was increased upto 1.80±0.40 kg per day in treated group and 1.15±0.20 kg per day in T2 group. Body weight changes in cows average 7.0±2.12 kg (T1 group), average 1.00±.71kg (T2 group). Milk fat of the T2 group was less than the T1 group. Milk fat of the T1 group was recorded 4.64±2.71gm per kg but in T2 group milk fat was recorded 4.31±2.31gm per kg.
