| dc.description | Goat is an important species of livestock especially in the Asiatic region.
Goat population in Asia constitutes nearly 63.6% of the total world’s
livestock population and in Bangladesh it constitutes about 7% of the total
Asiatic population (FAO, 2003). Throughout the history, the role and
contribution of goats in the tropical developing, countries have been
prominent. The prominence is associated by varied functional contribution
(meat, milk, fiber and skin), socio-economic relevance (security, income
generation and human nutrition) and stability of farming system (Devendra,
1992), | en_US |
| dc.description.abstract | The aim of this study was to develop a feeding system using Urea Molasses
Block (UMB) for weaned castrated goats under traditional grazing
condition. UMB may be used as a catalytic feeding for improving growth
performance of the indigenous goats. Twelve goats aged six months in each
were randomly allocated into four treatment groups. Goats (Control group,
To) were in only grazing and three treated groups were fed 200 g (T)), 300 g
(T2) and 400 g/head/d (T;) UMB with traditional grazing. Socio-economic
parameters, participation of family members and daily routine activities of
farmers were also observed. Live weight changes of goats were measured
weekly. Average initial and final live weight of different treatment groups
1.e. To, T;, T2 and T; were 10.30 vs 15.40, 9.20 vs 15.17, 10.20 vs 13.70 and
9.77 vs 14.03 kg respectively during 105 days of feeding trial. The average
live weight gain for treatment To, T;, T2 and T3; was 48.33, 56.33, 33.33 and
40.67 g/d, the carcass weight was 6.93, 6.42, 5.53 and 5.78 kg and the
dressing percentage was 45.10, 42.21, 40.40 and 41.19 for the aforesaid
treatments respectively. The eye muscle area of four treatment groups were
15.71, 16.34, 12.48 and 15.03) cm’ (P<0.05). Among the by-products
weight of head, liver, kidney, spleen, lung plus trachea and weight of blood
differs significantly of the four treatment groups. Cost benefit ratio
estimated was 1: 2.23, 1: 1.53, 1: 1.20 and 1: 1.10. Live weight gain,
dressing percentage and cost benefit ratio of the aforesaid treatment groups
were higher for control (To) than others but among the treated groups T (1),
T, and T3), was higher than T, and T3, So further research will necessary by
reducing the level of UMB to find the optimum level of weight gain and
profitability of Black Bengal goats. | en_US |
