Abstract: Traditional feeding system like feeding of green fodder available in pasture land as well as on private land and mainly Rice Straw & Wheat Straw feeding as a dry fodder throughout the year to milking animal causes low productivity, anoestrus and repeat breeding in animals. One of the methods of increasing utilization of straws is the supplementation of deficient nutrients in licking form so, that fermentable N, energy and minerals, available ensuring enhanced microbial growth in the rumen, which in turn enables the ruminants to consume more straw. But Urea mineral molasses licking block (UMMB) is not popular due to unavailability and addition of cementing materials. Therefore, an on farm trial of 60 days excluding 15 days preliminary periods and 15 days post feeding periods was conducted on 27 animals of 1 month after parturition to know the effect of feeding UMMB block manufactured by locally available feed ingredients and without binding materials on milk production, quality and reproductive performance of dairy animals. Animals feeding as farming practices were considered as control and 300g UMMB licking block in TO1 and in TO2 group 300g UMMB licking block was supplemented reducing concentrate by 20%. The milk yield was 8.16±0.2, 9.10±0.1 and 8.25±0.20 kg respectively which was significantly higher in TO1 than control and TO2 group. Increase in milk yield over control group was 0.640 and 0.190 kg more in TO1 and TO2 group than control group. The average fat% was 3.90±0.10, 4.0±0.12 and 3.80±0.13 in control, TO1 and TO2 group, respectively. It was statistically similar. Net return over feed cost was 10.40 and 4.65 Rs in TO1 and TO2 group, respectively. Decrease in inter calving period was 37 days and increase in conception rate was at first service by 42%. Hence, supplementation of UMMB blocks increase, the milk production, improves Fat% and increases the reproductive performance of dairy animals.
