Background: The onset of an industrial shift from grass to grain-supplemented feed has resulted in a rapid change human diets, specifically the ratio n-6 n-3 fatty acids; where saturated fats and acid consumption increased at expense acids. Although recent reports on global nutrition put emphasis health-related acids, profiling fat acids different breeds reared by farmers within same feeding re...

Insulin resistance plays a major role in the development of type 2 diabetes and may be causally associated with increased intracellular fat content. Transgenic mice with adipocyte-specific overexpression of FOXC2 (forkhead transcription factor) have been generated and shown to be protected against diet-induced obesity and glucose intolerance. To understand the underlying mechanism, we examined ...

31_T ued H E current image of pork as a food is in part to the concern about the relation of fat to cholesterol and heart disease. However, pork fat is unusually high among animal products in the unsaturated fatty acids. The variation in composition of lean, as well as the effects that different feeds, rate of gain or sex of animal have on this composition, is not clear. Certain feeds high in o...

Calves weaned on cow­calf operations throughout Arkansas even­ tually move on to stocker, feedlot and packer operations. Wide variations in carcass uniformity and consistency exist among these calves. Potential carcass problems can include inappro­ priate carcass size and weight, i nadequate tenderness, insufficient intramuscular fat (marbling) and excess external fat cover. Many of these quali...

The objective of this work was to investigate the effect of feeding conditions on methylation status of FATP1 gene, which is an important candidate gene of Intramuscular fat and important indicator of chicken meat quality. We selected Daninghe (DNH) and Qingjiaoma (QJM) chickens under scatter-feeding and captivity-feeding conditions as experimental animals, and detected the methylation status o...

There are three economically important traits under the CUlTent U. S. Beef Grading System: the distribution and amount of intramuscular fat (or marbling), the subcutaneous fat thickness, and the ribeye muscle size. These traits are also major factors used in evaluating body composition for genetic improvement. The marbling scores are visually graded by certified inspectors under the current USD...

For the range of fat content found in pork, the two chemical procedures studied for the estimation of intramuscular fat (IMF), Soxhlet and total lipid (TL), are highly correlated and values for the Soxhlet procedure are slightly lower. No significant (P<.05) differences existed between the two methods. Hence, both methods can be recommended for the determination of IMF in pork. The Soxhlet meth...

Introduction Obesity in dogs is a growing concern. Different surveys report a recent increase in dog obesity, their estimates ranging from 22 to over 50%. Surveillance of dog body condition score (BCS) is a routine practice but it is not sensitive enough. Ultrasound (US) assessment of body fat deposits was previously used in different species to predict adiposity, and shows several advantages, ...
