Lipotropic action of choline In 1924 Allan, Bowie, Macleod, and Robinson' reported that depancreatized dogs receiving adequate amounts of insulin and maintained on a diet of lean meat, sucrose, and bone ash did not survive for periods of longer than a few months. They also observed that symptoms of failure of liver function due to fat infiltration of the liver found in such animals could be pre...

I. Diets containing different proportions of skim milk and fat, either beef tallow or soyabean oil, supplemented with fat-soluble vitamins were given to 2-d-old pigs. Each fat source was used in three diets containing approximately 280, 350 and 420 g fat, and 260, 235 and 210 g protein/kg dry matter respectively. 2. The diets were given as a milk containing zoo g solids/l during a 26 d experime...

I . Tridodecyl glyceryl ether (I ,z,3-tridodecoxypropane) was prepared and purified for use as a lipid-soluble indicator of fat absorption. It was separated from other lipids present in samples of diet, digesta and faeces by thin-layer chromatography and determined by gasliquid chromatography. 2. In balance studies using rats which received a semi-purified diet containing beef tallow, 97-98 "/o...

Inositol was originally shown to be a lipotropic agent in rats maintained under special conditions (1) ; the animals were depleted of fat and of B vitamins by maintenance for 3 weeks on a fat-free, high carbohydrate diet, and during a subsequent week fat synthesis was promoted by a supplement of B vitamins and a beef liver fraction. Under these conditions the rats developed markedly fatty liver...

Net feed conversion efficiency (NFCE) describes whether an animal eats more or less feed than expected for its size and growth rate. Early results from the Trangie NFCE Project, and from the Beef CRC, show that considerable variation in NFCE exists within each of the British breeds tested and is moderately heritable. Estimates of heritability for average daily gain, 365-day weight, feed intake,...

Traditional analyses of a QTL on Bota 19 implicate a surfeit of candidates, but each is of marginal significance in explaining the deposition of healthy, low melting temperature fat within marbled muscle of Wagyu cattle. As an alternative approach, we have used genomic, multigenerational segregation to identify 14 conserved, ancestral 20 Mb haplotypes. These determine the degree and rate of mar...

BACKGROUND The conjugated linoleic acid (CLA) content of beef can be increased by supplementing appropriate beef cattle diets with vegetable oil or oil seed. Yet the effect of consumption of such beef on adipose tissue characteristics is unclear, thus the study was conducted to compare adipose tissue responses of rats to diets containing beef from steers either not provided or provided the oil ...

Introduction The “Grass-fed beef ” label indicates meat that is produced by feeding forages from start to finish without any grain supplementation (USDA-AMS 2007). Many healthful aspects of grass-fed beef have been identified, including lower total fat content and higher content of omega-3 fatty acids, conjugated linoleic acids (CLA), and antioxidants as compared to feedlot-finished beef (Razmi...

Consumers are increasingly becoming more aware of the relationships between diet and health. The functional–food components of beef and milk fat include ω–3 polyunsaturated fatty acids (PUFA) and conjugated linoleic acid (CLA). Beef typically has high saturated fatty acid content and low PUFA content, but the content of beneficial fatty acids can be increased by dietary manipulation. Dietary li...

Coronary heart disease and a number of other diseases have been shown to increase with consumption of foods high in saturated fat and cholesterol. However, increased consumption of n − 3 fatty acids reduces the incidence of these diseases. Llama meat has been reported as having a lower fat content, lower saturated fat content, and a higher n− 3 fatty acid content than beef, and hence may serve ...
