| Popis: |
A total of 96 pigs (Yorkshire; 54.3 ± 3.4 kg body weight) were used to investigate the effect of dietary lipid (0 or 1% flaxseed oil + 1, 3, or 5% poultry fat for the diets supplemented with lipids) and vitamin E (11 or 220 IU vitamin E/kg) supplementation in a 4 × 2 factorial arrangement of treatments on the physical and organoleptic characteristics and fatty acid (FA) profile of pork, and the expression of genes associated with lipid metabolism. Forty-eight pens containing 2 gilts or 2 castrated males were randomly assigned to 8 treatments with 3 gilt pens and 3 castrated male pens per treatment. Pigs were harvested when they reached approximately 110 kg. Muscle and adipose tissue samples at the last rib were collected to determine the expression of genes associated with lipid metabolism. Loin muscle samples were collected for the determination of the physical and organoleptic characteristics and FA profile of pork. The percentage of the saturated FA and monounsaturated FA decreased linearly (P |
