Fatty acid composition of the longissimus dorsi muscle in crossbred steers fed different sources of fatty acids

Intramuscular Fatty Acid Composition of the Longissimus Muscle of Unweaned Minhota Breed Calves at Different Slaughter Age

Meat productions from sixteen local Portuguese cattle breeds represent high economic and cultural value for local populations. Among these, Minhota is one of the most important on meat aptitude located on the northwest of the country. This breed is used for high-quality meat. This study describes the influence of slaughter age, corresponding veal (6 months) and beef (9 months) and sex, reared i...

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. ...

Fatty Acid Profles of Ram's Sperm after Removing Some Fatty Acid Sources from the Diets and Persistency of Fatty Acids in Sperm

Effects of diets enriched in different sources of fatty acids on reproductive performance of Zel sheep

The present study evaluated the effects of diets enriched in saturated and polyunsaturated fatty acids (n-3and n-6) on reproductive indices, metabolic hormones and metabolites prior to ram introduction in oestrussynchronized ewes. Zel ewes (n=188) were assigned to 4 groups. Ewes in the control group (CON) did notreceive fat. Ewes in the 3 other groups received 3% oil/DM/day of palmolein oil (PL...

Fatty acid profile, and chemical composition of Longissimus muscle of bovine steers and bulls finished in pasture system.

The objective of this work was to evaluate the conjugated linoleic acid content (CLA), the fatty acid profile, and the chemical composition of the Longissimus muscle (LM) of steers and bulls finished in pasture systems. Fourteen 1/2 Nelore×1/2 Aberdeen Angus cattle were studied. The animals were slaughtered at approximately 20 months of age, with an approximate final liveweight of 480kg. Moistu...
