Context Soxhlet extraction is commonly used for determining fat content of meat, because it the basis AOAC Final Action method this analysis. Petroleum ether as an solvent but other solvents, such chloroform, can be used. Chloroform has been stated to a safer than petroleum and extensively meat research in Australia; yet, there no report that validates its use purpose.Aim To compare chloroform ...

Cow/calf and feedlot producers and those who provide professional assistance to them are very aware of the need to produce feeder/fed cattle profitability, but often fail to put sufficient emphasis on ensuring consumers a quality and consistent beef product. A heightened awareness of the importance of beef quality and consistency has occurred throughout the beef industry during the 1990s. The f...

Nutrient Content of Beef Steaks as Influenced by USDA Quality Grade and Degree of Doneness. (April 2010) Amanda Marian Smith Department of Animal Science Texas A&M University Co-Research Advisors: Dr. Jeffrey W. Savell Dr. Kerri B. Harris Department of Animal Science The purpose of this study was to determine the influence of various degrees of doneness on the nutrient content of beef. Ten stea...

The purpose of this investigation was to determine whether diets high in animal or vegetable fat affected mammary tumorigenesis when fed to rats only prior to and during the initiation phase of carcinogenesis. Weanling 21-day-old female SpragueDawley rats were divided into different dietary treatment groups and were allowed to feed ad libitum on one of the following diets: 5% (normal fat) com o...

The influence of feeding systems on the levels of functional lipids and other fatty acid concentrations in Australian beef was examined. Rump, strip loin and blade cuts obtained from grass feeding, short-term grain feeding (80 days; STGF) and long-term grain feedlot rations (150-200 days; LTFL) were used in the present study. The typical Australian feedlot ration contains more than 50% barley a...

Beef is a nutrient-rich, high-quality protein containing all the essential amino acids in proportions similar to those found in human skeletal muscle. In order to investigate the efficacy of a beef supplementation strategy on strength and body composition, we recruited 26 young healthy adults to participate in a resistance-training program of eight weeks, based on the use of isotonic machines a...

The aim of the present study was to determine the influence of age of animal, hot carcass weight, pH, conformation and fat class on basic beef quality attributes (tenderness, sarcomere length, basic chemical composition, marbling and colour) in a group of purebred animals. The object of the study was beef of Limousin bulls (25 to 27 months, hot carcass weight - 432±31 kg, "U" conformation class...

Eighteen male English Pointers (2-4 years of age, 23.94+/-0.54 kg body weight) were allotted to three diet and two physical conditioning groups to evaluate the effect of level and source of dietary fat on the olfactory acuity of canine athletes subjected to treadmill exercise. Diet groups (6 dogs/diet) consisted of commercially prepared diets (minimum of 26% crude protein) containing 12% fat as...
