Effect of Urea Molasses Multinutrient Block on the Reproductive Performance of Indigenous Cows under the Village Condition of Bangladesh
In the present study urea molasses multinutrient blocks (UMMB) may be used
as a catalytic feeding to the straw based diet of the indigenous cows for fertility.
With that understanding, 49 indigenous post partum cows from 49 marginal village
farmers of village-Boira were selected and a cake of 250 g/h/d UMMB was supplied
with their usual feeding from date to calving to the date of confirmation of
pregnancy. Cows were stall fed. Reproductive events of cows were recorded as
when occurred. Milk progesterone was measured by using radio immuno assay (RIA)
technique. Similarly, 49 cows were in control group in the same village. The
results in control and UMMB group were-calving to 1st p4 (progesterone) rise
(days) 104±52 and 103±37 (p>0.05); calving to first service (days) 194±68
and 130±64 (p<0.01); calving to conception (days) 199±72 and 162±73 (p>0.05)
and subsequent calving interval (days) 480±73 and 443±70 (p>0.05), respectively.
From the study, it may be concluded that UMMB has a positive effect on fertility
of the local cows under the village condition of Bangladesh.
