Effect of plant tannin-containing diet on fatty acid profile in meat goats
ثبت نشده
چکیده
Phytochemical plant tannins are phenolic compounds that interfere with biohydrogenation (BH) of monounsaturated-(MUFA) and poly-unsaturated fatty acids (PUFA). The objective of the present animal study was to investigate the effects of three different levels of phytochemical tannin-containing ground pine bark diet on fatty acid profiles of goat meat, with particular reference to MUFA and PUFA. The saturated fatty acids (SFA), PUFA, and PUFA/SFA ratios in subcutaneous adipose tissue as well as MUFA and PUFA composition of mesenteric kidney fat were increased with increasing phytochemical tannin-containing ground pine bark supplementation. The study showed that phytochemical plant tannins could be a means to moderate the accumulation of unsaturated fatty acids with the aim of improving percentage of these PUFA/SFA ratios in goat meat. The effects would be useful to improve carcass fatty acids composition and human health.

An experiment was conducted to compare the effect of corn-soybean meal finisher (29-42d) diets containing flaxseeds (rolled or extruded) on pellet quality, performance, n-3 fatty acids (FA) and oxidative stability of meat in broiler chickens. Seven pelleted diets were provided in a 3×2 factorial arrangement with three flaxseed levels (5, 10, and 15%) and two processing methods (rolled or extrud...

Little scientific information is available that has evaluated safflower (Carthamus tinctorius) cake as a substitute to conventional ingredients in small ruminants diet. The objective of this work was to evaluate the effect of feeding safflower cake in total mixed rations (TMRs) on lamb and kid growth rates, carcass traits and meat fatty acid composition. Two consecutive trials were conducted us...

A total of 21 dairy goats in mid lactation were randomly assigned to three experimental diets in a completely randomized design. The diets contained 0, 3, or 6% WAS, and consisted of 45% forage and 55% concentrates. Milk fat and the ratio of milk fat to milk protein were significantly lower in goats fed diets containing 6% WAS (P≤0.01). Digestibility of crude fat was higher, and that of neutral...

The purpose of this experiment was to investigate the effect of one-week feeding of flaxseeds (rolled/extruded) on performance, n-3 fatty acids and oxidative stability of meat in broiler chickens. Seven pelleted diets (36-42d) were provided in a 3×2 factorial arrangement with three flaxseed levels (5, 10, and 15%) and two processing methods (rolled/extruded) and a zero flaxseed control diet.
