Innovations in beef production systems that enhance the nutritional and health value of beef lipids and their relationship with meat quality.
TLDR
Strategies for increasing the content of beneficial omega-3 polyunsaturated fatty acids (PUFA) and conjugated linoleic acid (CLA) and reducing saturated fatty acid (SFA) in beef are reviewed and opportunities exist to enhance thecontent of health promoting fatty acids in beef and beef products offering opportunities to add value and contribute to market differentiation.

Effect of a grass-based and a concentrate feeding system on meat quality characteristics and fatty acid composition of longissimus muscle in different cattle breeds
TLDR
The grass-based system increased the percentage of C18:1 trans fatty acid isomers in both breeds and the content of the beneficial n -3 polyunsaturated fatty acids and conjugated linoleic acids in beef muscle was significantly higher in animals on the grass- based system. Expand
The effects of gender, age and region on macro- and micronutrient contents and fatty acid profiles in the muscles of roe deer and wild boar in Mecklenburg-Western Pomerania (Germany).
TLDR
Samples of M. longissimus were collected from a total of 203 feral roe deer and wild boar in two regions of Mecklenburg-Western Pomerania (Germany) and Germany and the major vitamin E homologue, α-tocopherol, was determined to be between 5.8 and 13.1mg/kg in roe Deer muscles. Expand
Meat quality and fatty acid composition of lipids in muscle and fatty tissue of Skudde lambs fed grass versus concentrate
TLDR
The objective of the experiment was to accumulate n-3 fatty acids and conjugated linoleic acids (CLA) in muscle and subcutaneous fat in Skudde lambs by feeding grass to concentrate by increasing the concentration of CLAcis-9, trans-11 and C18:1trans-11 in muscle fat of Skud de lambs. Expand
Effect of pasture vs. concentrate diet on CLA isomer distribution in different tissue lipids of beef cattle
TLDR
Overall, pasture feeding resulted in significantly increased concentrations of the sum of CLA isomers in the lipids of longissimus, muscle, subcutaneous fat, heart and liver muscle of German Holstein and German Simmental bulls, but not in semitendinosus muscle. Expand
Enhancing the nutritional and health value of beef lipids and their relationship with meat quality.
This paper focuses on dietary approaches to control intramuscular fat deposition to increase beneficial omega-3 polyunsaturated fatty acids (PUFA) and conjugated linoleic acid content and reduceExpand
Effects of polyunsaturated fatty acids from plant oils and algae on milk fat yield and composition are associated with mammary lipogenic and SREBF1 gene expression.
TLDR
Examination of long-term supplementing diets with saturated or unprotected polyunsaturated fatty acids from two different plant oils rich in either n-3 or n-6 fatty acids plus docosahexaenoic acid (DHA)-rich algae on mammary gene expression and milk fat composition in lactating dairy cows found a positive relationship between mammary SCD1 and SREBF1 mRNA abundances was observed, suggesting a similar regulation for these genes. Expand
Effect of grass vs. concentrate feeding on the fatty acid profile of different fat depots in lambs
TLDR
The aim of this study was to produce high-quality meat from lambs under different feeding conditions, as measured by the accumulation of n-3 fatty acids and conjugated linoleic acids (CLA) in muscle and subcutaneous fat by measuring the concentration of C18:1trans-11 in total muscle lipids, phospholipids, triacylglycerols and sub cutaneous fat. Expand
Carcass- and meat quality of pasture vs concentrate fed German Simmental and German Holstein bulls
TLDR
Pasture feeding resulted in a significant increase in the concentration of n-3 fatty acids up to a factor of 2.8 in longissimus muscle of bulls compared with the concentrate feeding system and colour investigations of both muscles showed that the beef produced by pasture feeding is darker. Expand
Effect of diet on the deposition of n-3 fatty acids, conjugated linoleic and C18:1trans fatty acid isomers in muscle lipids of German Holstein bulls.
TLDR
The effects of feeding diets rich in either n-3 or n-6 polyunsaturated fatty acids (PUFA) on the fatty acid composition of longissimus muscle in beef bulls and the pasture feeding affected the distribution of individual CLA isomers in the muscle lipids. Expand
