|
This study was conducted to investigate the effects of (a mineral mix) supplementation on growth performance, nutrients digestibility, blood characteristics, meat quality and carcass traits in weaning-to-finishing pigs. A total of 48 crossbred pigs with initial body weight (BW) of were used in a 21 wks trial. Pigs were blocked by weight and allotted to two dietary treatments in a completly randomized design. There were 6 pens per treatment. Dietary treatments included: 1) Control (CON: basal diet) and 2) MT (basal diet+0.8% ). Through the entire experimental period, there were no effects of dietary supplementation on growth performance nutrients digestibility, blood characteristics and meat quality traits (p>0.05). Market weight and backfat thickness also had no differences between the two treatments (p>0.05). However, carcass weight and carcass ratio in MT treatment were improved significantly compared with CON treatment (p<0.05). In conclusion, supplmentation of can increase carcass weight and carcass ratio in weaning-to-finishing pigs, however, it has no effects on growth performance, nutrients digestibility, blood characteristics and meat quality traits.
