FATTY ACID COMPOSITION OF LONGISSIMUS DORSI MUSCLE OF BLACK GOATS AND MERIZ KIDS AS INFLUENCED BY CASTRATION AND SLAUGHTER WEIGHT
نویسندگان
چکیده
To investigate the effect of castration and live body weight at slaughter on fatty acid composition, a total 48 entire male kids (24 Meriz 24 Black goat) were selected weaning (90-120 days age) weighing 10.99 11.21kg, respectively from commercial goat farm used. After an adaptation period for week, both breeds randomly divided in to two groups, first was castrated, whereas second groups left intact, then allocated be slaughtered 15,20 25kg weight. All placed individual pens fed concentrate diet weighed weekly interval. slaughtering chilling carcass 24h fed. The L. dorsi muscle removed each utilized composition. Results obtained revealed that saturated acids (SFAs)have highest contribution, followed by poly unsaturated (PUFAs) mono -unsaturated (MUSFs). Kids had significantly (p<0.01) higher content C18, C14, C11, C18:2 C18:3 than kids, surpass C16, difference between two-breed lacked significance C18:1.Also, it shown castrated proportion all studied as compared intact profiles lower 15kg 20 25kg.

Comparison of the Fatty Acid Composition of the Longissimus Dorsi Muscle of Kids, Lambs and Calves Produced under Iranian Transhumant Production System
Transhumant production system (TPS) is a type of extensive livestock production practiced by transhumant pastoralists in which indigenous livestock breeds are mainly fed a pasture-based diet. The hypothesis tested in this work was whether differences existed between fat samples from the different species in respect to ratios of n-6/n-3, and polyunsaturated fatty acids to saturated fatty acids. ...

This study was conducted to determine the effects of dietary addition of tea saponins (TS) and soybean oil (SO) on fatty acid profile and gene expression of stearoyl-CoA desaturase (SCD) in longissimus dorsi (LD) muscle of growing lambs. Thirty-two Huzhou lambs were assigned to four dietary treatments in a 2×2 factorial arrangement with main effects of TS (0 or 3 g/d) and SO (0 or 30 g/kg of di...

Crossbred pigs (n=288) were used to test the interactive effects of dietary fat source and slaughter weight on live performance, carcass traits, and fatty acid composition of the LM. Pigs were blocked by initial BW, and, within each of 9 blocks, pens (8 pigs/pen) were randomly assigned to either control corn-soybean meal grower and finisher diets devoid of added fat (Ctrl) or diets formulated w...
