Effect of dietary selenium and vitamin E on chemical and fatty acid composition of goose meat and liver*

چکیده
The effect of dietary supplementation with organic selenium and vitamin E on chemical characteristics and fatty acid composition of goose meat (breast and leg muscles) and liver is described. Twohundred one-day-old White Koluda® goslings were randomly divided into two groups balanced by sex, with five replicates each. Up to week 13 of age the control group was fed basic feeds, while the experimental group was fed the basic feeds supplemented with 0.3 mg/kg organic selenium (Se) and 100 mg/kg vitamin E (Vit. E). For the fattening-finishing phase during weeks 14-16 both groups were fed identically with oat grain and ground cereals. Feed supplementation with 0.3 mg/kg Se and 100 mg/kg Vit. E resulted in the production of goose meat and liver with significantly higher selenium contents, 1.88-2.25-fold higher in meat and 1.68-fold greater in the liver. Other chemical traits of breast and leg muscles, as well as the fatty acid profile of intra-muscular fat were not affected by the applied supplements, although with some minor effects due to the sex of geese.

This study was conducted to determine optimal ratios of dietary linolenic acid (18:3n-3, LnA) to linoleic acid (18:2n-6, LA) for Tor tambroides. Juveniles were fed three trial diets with different ratios of LnA/LA (0.0, 0.5 and 1.0) for 10 weeks. Another diet contained 100% palm oil, which was similar tothe diet with 0.0 LnA/LA ratio but different in total amounts of C18polyunsaturated fatty ac...

This study aimed to produce omega-3-emriched broiler meat by using ultrasonicated flaxseed oil nanoemulsions coated with whey protein-sodium alginate. Three hundred 1-d-old (Ross, 308) male broiler chicks were allocated randomly to 5 experimental treatments with 4 replicate pens. Experimental treatments included basal diet (BD), basal diet plus flaxseed oil (BD+FO, 1 mL/kg/BW), basal diet plus ...
