Abstract
The experimental animals of 10 to 12 months of age, having about 10-
12 kg body weights were selected. Blood sample was collected aseptically
from the jugular vein of the experimental animals. To collect the serum, blood
was collected without anticoagulant and allow to clot at room temperature by
placing the tube in slanting position. The clear supernatant serum was poured
off into vial along the side of the tube, serum was refrigerated until analysed.
The genetic make up and environmental effect differentiate the different
breeds of goat. It is expressed by the synthesis and degradation through
metabolism of different substrate and exchange of metabolites. The study on
these metabolites and as well as minerals were under taken to compare
variation as well as breeds characteristics of Black Bengal (BB) and its
crosses, Black Bengal X Beetal (BTB), Black Bengal X Sirohi (BS).
Blood samples were collected from experimental animals from three
groups i.e. Gr. I (BB), Gr. II (BTB) and Gr. III (BS) from jugular vein. Serum
was obtained and stored till analysis was overed. Among the biochemical
constituents total serum lipid was appeared to be higher (2.974 ± 1.1448) gL-
1 in BTB followed by BB and BS. Such variation might be due to less water
retention in muscle as the amount of water in lean meat is greater than fat
meat. Total fatty acids content in serum were found to be more in BB (0.1358
± 0.0129) mML-1 with respect to BTB and BS. It might be due to variation in
lipid metabolism in which these molecules are utilized for energy purpose in
ruminants.
Total serum cholesterol reveal no significant difference among three
genetic group.

Glycerides appears to be significantly low (p < 0.01) in BB (0.123 ±
0.006) mML-1 as compared to BTB and BS such finding affects the fat
deposition in the body tissues as confirmed by indicating estirification with free
fatty acids.
Like cholesterol, total serum phospholipid did not showed variation,
which are mainly associated as a structural lipid. Sodium and potassium level
in serum of BB and its crosses (BTB and BS) were not found significant
different. However, potassium level were found to be low as compared to
sodium among all crosses (BTB, BS and BB).
Based on the present findings, Black Bengal and its crosses can be
characterized biochemically as per neutral lipids specially fatty acids and
glycerides.
Serum mineral specially sodium and potassium level can not be used
for characterization biochemically.
The detail biochemical characterization of fatty acids and glycerides
specially from muscles are suggested for future studies in these species,
which may be useful for meat quality.
