Abstract
Effects of levels of Bomboo Vinegar Liquids(BVL) on growth performance, serum profile and meat quality in employing 90 pigs were investigated. Ninety pigs were allocated into 3 groups and fed by dietary levels of BVL 0(control), 2.0 and 4.0% were included in experimental diets of each of the groups. Concentrated diet was supplemented with 2.0 and 4.0% BVL. The results showed that the daily weight gains and the feed conversion increased significantly(p<0.05) in 2.0% BVL and the feed intake increased slightly. The glucose and the cholesterol contents at the serum decreased significantly(p<0.05) in 2.0 and 4.0% BVL. On the other hand the total protein concentration and the blood urea nitrogen(BUN) increased significantly(p<0.05) in 4.0% BVL. The carcass weight increased significantly(p<0.05) in 4.0% BVL, and back fat thickness had decreased significantly(p<0.05) in 2.0 and 4.0% BVL. The carcass grade tended to increase in 2.0 and 4.0% BVL. The total fat content of loin tended to increase in 2.0 and 4.0% BVL while the cholesterol content decreased significantly(p<0.05). The pH had lower slightly in 2.0 and 4.0% BVL, the lightness and the yellowness of the meat color had higher significantly(p<0.05) while the redness decreased. Shear force values had lower significantly(p<0.05) in 2.0 and 4.0% BVL. For the fatty acid composition, the saturated fatty acids decreased significantly(p<0.05) in 2.0 and 4.0% BVL while unsaturated fatty acids(oleic acid and linoleic acid) increased significantly(p<0.05). For the sensory evaluation, 2.0 and 4.0% BVL had a significant(p<0.05) effect of diminishing the odor and improving the appearance. The taste was also significantly(p<0.05) improved. In conclusion the 2.0% BVL had a positive effect on the feeding performance, the carcass grade and the meat quality characteristics therefore 2.0% BVL is the appropriate supplemental levels of BVL for finishing pigs.
