Abstract:

This study was conducted to compare the performance of crossbred cow likely L×F (50% L and 50% F), L×H×F×F×L×F (68.75% F, 28.125% L and 3.125% H), L×F×F (75% F and 25% L), L×F×L×F×F (81.25% F and 18.75% L), L×SL (50% L and 50% SL), L×SL×SL (75% SL and 25% L), L×SL×F (50% F, 25% L and 25% SL), L×S (50% L and 50% S) and L×Rc (50% L and 50% Rc). A total of 240 crossbred cows were selected from five upazilas of Comilla district. It was observed that mean milk yield per day for L×F, L×H×F×F×L×F, L×F×F, L×F×L×F×F, L×SL, L×SL×SL, L×SL×F, L×S and L×Rc crossbreds cattle were 6.03±0.5, 7.3±0.6, 9±0.5, 10±0.5, 4.51±1.06, 5±1.06, 4.16±0.81, 4±0.5 and 3±0.5 litre, respectively. The lactation length of L×F, L×H×F×F×L×F, L×F×F, L×F×L×F×F, L×SL, L×SL×SL, L×SL×F, L×S and L×Rc crossbreds cattle were 285±5, 285±5, 285±5, 285±5, 251±5, 253±5, 259±5, 248±5 and 220±5 days, respectively. About the reproductive performances L×F, L×SL and L×SL×SL cross breed cattle need minimum (1.61±0.61) services per conception and LxS crossbred cattle need maximum (1.78±0.63) services per conception. Gestation length was shorter (277±3.31 days) in case of L×Rc cross and highest (279.7±4.2 days) in case of L×SL×SL crossbred cattle. The highest calving interval was 447±20 days and found in L×S crossbred cattle and the lowest calving interval was 430±20 days and observed in L×F, L×H×F×F×L×F, L×F×F and L×F×L×F×F crossbred cattle. Calving interval was lower (430±20 days) in L×F, L×H×F×F×L×F, L×F×F and L×F×L×F×F crosses and higher (447±20 days) in L×S crossbred cattle. Age at puberty was shorter in L×SL×F cross 26.2±2.4 months and longer in L×SL×SL cross 29.3±2.3 months. Based on the results obtained from current study, it can be concluded that the L×F (50% L and 50% F) crossbred cattle is more suitable under climatic and socio-economic condition of Comilla district in Bangladesh.
