ABSTRACT

Evaluation of carcass performance and meet quality of pigs raissing in bio-bedding in Thong Nhat district, Dong Nai province

The experiment was conducted to evaluate the effect of raising swine on bio-bedding and/or cement floor on carcass performance and meat quality. Three hundreds and sixty commercial crossbred pigs (Duroc x Yorkshire x Landrace) were used in three trials; of which 120 animals per each trial were raised on 3 households. There were 20 pigs raissing on bio-bedding and the other 20 pigs raissing on cement floor (control group) in each farm, they were the same in breed, age, body weight and diet. After 5 months of raising, 36 pigs were slaughtered to evaluate carcass yield and meat quality (18 pigs from  bio-bedding group and 18 pigs from control group) Results show that the average slaughter weight, carcass percentage, dressing percentage of bio-bedding group and control group weren’t significantly different these were 112.68 kg and 112.10kg; 82.7%  and 82.8%; 74.4% and 73.3%  respectively. Lean meet percentage, loin eye tend to higher and backfat thickness tend to lower in bio-bedding group (58.7% and 58.1%; 50.5cm2 and 49.8cm2; 11.8mm and 12.2mm respectively). Crude protein, crude fat content were not significantly different between two experimental groups. The pH of logissimus dorsi muscle at 45minute (6.09 and 6.04), 24h (5.62 and 5.53) and L*24 (46.7 and 47.4) of  meet after slaughtering in two groups weren’t different between 2 experimental groups and in the range corresponding to the normal meat and drip loss tend to lower in the bio-bedding group. Thus raising pigs on the bio-bedding contributed to improve the productivity and meet quality.

Key words:  Carcass performance, meat quality, bio-bedding, crossbred pigs
