EFFECT OF SWEET JUMBO GRASS (Sorghum bicolour Sorghum sudanefe) ON CROSSBRED AND LOCAL MILKING COWS AVAILABLE IN CHAR AREAS OF PABNA SADAR UPAZILA OF BANGLADESH

Abstract

This study was conducted for a period of 6 months at char areas of Pabna Sadar Upazila under Pabna District to evaluate the effect of sweet jumbo grass on productive and reproductive performance of Sahiwal cross bred (L×SH) and Local (L) milking cows. A total 08 number of crossbred milking cows and 08 number of local milking cows (L×SH, 08 and L, 08) were selected from the study area and reared three months under feeding with high yielding sweet jumbo and road side green grass and they were assigned into two groups (treatment & control group). The productive performances like, daily milk yield, milk composition especially fat%, body weight gain of cow and reproductive performances like post-partum heat period and service per conception were studied by collecting data through a well prescribed questionnaire. The results revealed that among the productive parameters; daily milk yield was significantly (p<0.05) improved in the crossbred (L×SH) and local (L) milking cows which were fed high yielding sweet jumbo green grass compared to the cows were fed road side green grass. On the other hand milk fat%, body weight gain, post-partum heat period and service per conception were also improved (p<0.05) in the crossbred and local milking cows. So, it is suggested that to achieve the desire productive and reproductive performance of crossbred and local milking cows may be improved by feeding high yielding sweet jumbo green grass
