Antioxidant vitamins, Pig performance and Pork quality.
The effects of the pharmaceutical levels of single and combined antioxidant vitamins: A, C, AC, AE and CE on growing pig performance, pork quality in respect to malondialhyde (MDA) serum concentrations and drip loss were investigated. 36 pigs of average body weight (BW) of 6 ± 0.79 were randomly divided into one of six experimental groups. The animals received similar commercial diet for one week after which they were offered their experimental diets at 5% of their BW as: To (control diet – contained vitamins at their basal levels, TA (200mg of vitamin A), TC (200mg of vitamin C), TAC (100mg of vitamin A + 100mg of vitamin C), TAE (100mg of vitamin A + 100mg of vitamin E) and TCE (100mg of vitamin C + 100mg of vitamin E)/kg of diet, respectively for 4 weeks. Animals on the antioxidant vitamins, especially those on the combined vitamins gained at significant (P < 0.05) better rates compared with the control group. Similarly, the feed efficiency (FE) of the vitamin diets were significantly (P < 0.05) superior compared with control despite the similar (P > 0.05) feed intakes. Furthermore,the vitamin diets particularly the combined vitamin diets demonstrated lower MDA concentrations as well as lower drip loss (P < 0.05) compared with the control group. It was concluded that antioxidant vitamin combinations improved pig performance and pork quality by significantly reduced MDA levels and drip loss.
