Abstract/ Executive Summary:

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 (p0.05) 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.

Program Area: Animal Health and Management

Commodity: Ureamollases

Objectives:

1. To study the effect of UMMB on the reproductive intervals i.e. 1st p4 (progesterone) rise, calving to first estrus, calving to conception and calving interval.

2.To assess the profitability of UMMB in terms of diet economy especially in the straw based diet in Bangladesh.

Methodology:

One typical village-Boira which is about 2 km away from Bangladesh Agricultural University (BAU), Mymensingh, was chosen for this study for improving milk production and fertility of the local cows. The villagers are mostly resource poor farmers (small-holder farms) and 22% of them are landless but every family has some indigenous cattle. The cows of the villagers are used for multipurpose such as drought, dairy as well as meat. Rice straw is the main source of feed for the animals. Very little roadside grass, concentrates e.g. wheat bran, oil cake, rice bran and common salt are fed to the animals. Animals are mainly stall fed and sometimes tethered. Calves are usually tied at night and free access to their dam during day time. From 2 July 1995 to 16 January 1996, 80 individual resource poor village farmers with their 98 postpartum cows in total had been selected. Blocks were being used as catalytic feeding to the straw based diet of the local cows for fertility. Two hundred and fifty g/h/d of UMMB were being supplied to the cows in addition to their usual feeding by the farmers from date of calving to the date of confirmation of next pregnancy by rectal palpation. Blocks contained molasses 53%, wheat bran 16%, rice polish 16%, common salt 5%, lime 4% and urea 6%. An electric powered concrete mixture machine has been set for mixing the feed ingredients and a ball press and mold with lever system is being used for the preparation of UMMB by cold method. For standardization and quality control frequent analysis of nitrogen content of the block were being done by Kjeldahl method. The chemical composition of UMMB was DM, 81.57%; CP, 18.75%; CF, 3%; EE, 2.2% and Ash, 16.62%. Besides this, CP was estimated once a month from the start to end of the experiment. The production responses (biological/economical) after supplementation of UMMB were being recorded routinely-measurement of progesterone (p4 in serial samples of milk were being done by radio immuno assay (RlA) technique from 30 after calving to 7 interval until confirmation of pregnancy by rectal palpation together with records on reproductive events. The chemical composition of supplied feed ingredients, which were done in the Animal Nutrition Laboratory of Bangladesh Agricultural University. Statistical analysis of the collected and calculated data were carried out to analyzed of variance in randomized complete block design according to Gomaz and Gomez, test was carried out to find out the significant difference between means.
