The aim of the present study was to assess the effect of slaughter and carcass weight, age at slaughter and sex on the fatty acid profile of the Greek Boutsiko sheep breed. Twenty lambs (ten females and ten males) were examined. The lambs were slaughtered at the age of 48 days. Carcasses were chopped in nine specific cuts and a random sample of 100 g was taken from each cut, with a total of 180...

The objective of this study was to evaluate the impact of diets enriched with plant oils or seeds, high in polyunsaturated fatty acids (PUFA), on the fatty acid profile of sheep intramuscular and subcutaneous adipose tissue (SAT). Sixty-six lambs were blocked according to initial body weight and randomly assigned to six concentrate-based rations containing 60 g fat/kg dry matter from different ...

The relevance of dietary fatty acids (FA) for blood lipids should be assessed in the context of substituting nutrients. Such evidence is lacking for adolescents. This study describes prospective associations of dietary FA with changes in serum lipids during adolescence, and considers the theoretical isocaloric replacements of saturated FA (SFA) with other FA or carbohydrates (CHO). Children fro...

MODULATION OF ADIPOKINES BY N-3 POLYUNSATURATED FATTY ACIDS AND ENSUING CHANGES IN SKELETAL MUSCLE METABOLIC RESPONSE AND INFLAMMATION Justine Maye Tishinsky Advisor: University of Guelph, 2012 Dr. Lindsay E. Robinson Adipose tissue represents an important endocrine organ that secretes a multitude of adipokines known to mediate inflammation, lipid metabolism, and insulin sensitivity in peripher...

Due to supporting evidence that dietary patterns may have a significant role in the maintenance of good physical performance with aging, we tested whether plasma fatty acids, saturated fatty acids (SFA), and polyunsaturated (PUFA) fatty acids are cross-sectionally associated with different physical performance and predict changes in physical performance over a 3-year period. Data were from the ...

Eighteen steers were used to evaluate the effect of supplemental corn oil level to steers grazing endophyte-free tall fescue on fatty acid composition of LM, stearoyl CoA desaturase (SCD) activity and expression as well as cellularity in s.c. adipose. Corn oil was supplemented (g/kg of BW) at 0 (none), 0.75 (medium), and 1.5 (high). Cottonseed hulls were used as a carrier for the corn oil and w...

The object of research is the fatty acid composition milk-fat base for combined food products a healthy diet. biological effectiveness fats determined by ratio saturated (SFA), monounsaturated (MUFA) and polyunsaturated (PUFA) acids, including omega-3 PUFA: omega-6 PUFA. Not all foods have balanced composition, in particular, dairy contain excessive amounts SFAs, consumption which leads to an i...

Beef and lamb, are a food category with positive and negative nutritional attributes. Rumi‐ nant meats are major sources for many bioactive compounds including iron, zinc and B vita‐ mins. However they are associated with nutrients and nutritional profiles that are considered negative including high levels of saturated fatty acids (SFA) and cholesterol. It is well know that the low PUFA/SFA and...
