EFFECT OF THE DEPRIVATION OF MINERAL AND VITAMIN SUPPLEMENT ON LIPID-PEROXIDATION IN PIGS

Kahyb piglets, 30 kg body weight, were divided into three groups. The control group received 0.54 g 100 g(-1) ISV-647 mineral and vitamin su pplement (premix) in the feed. Group 2 was deprived of the supplement when the animals reached a body weight of 75 kg. No supplement (premix ) was given to animals in group 3. From economic point of view body we ight gain appeared favourable in partial supplement deprivation group. Fat content was highest in the spare ribs of control pigs. Malondiald ehyde levels were higher in the pork tissues having high fat content. Supplement deprivation had no effect on malondialdehyde levels in pork and liver, probably due to a reduction in dietary levels of proxidant s and antioxidants, too. Conjugated dienes were significantly elevated in the group of total supplement deprivation. The intensity of lipid peroxidation processes was higher in certain pork tissues originally h aving a high fat content.
