The objective of this study was to determine the effect of slaughter season on the fatty acid profile in four types of fat deposits in crossbred (Polish Holstein Friesian Black-and-White×Limousine) beef bulls. The percentage share of fatty acids was determined by gas chromatography and were divided into the following categories of fatty acids: saturated (SFAs), unsaturated (UFAs), monounsaturat...

The livestock and meat industry is under increasing pressure to reduce fat while maintaining tenderness and palatability of its products. In the case of slaughter cattle, considerable variation exists in composition of beef carcasses and tenderness of product, a significant part of which is genetic in origin. In this paper, results from the Germplasm Evaluation (GPE) program at the Roman L. Hru...

Introduction Conjugated linoleic acid (CLA), a naturally occurring trans fat, is commonly found in ruminant animal sources such as beef, lamb, and dairy products (e.g., milk and cheese). Over the past two decades a wealth of research, mainly from in vitro and experimental animal studies and limited human investigations, has examined potential health benefits of CLA. This research on the biologi...

  this study was carried out from October 1993 through November 1995(26 months).during this period 3472 patients(2743 male and 729 female) with long bone and/or pelvic fracture were admitted in different wards of Shahid Bahonar hospital of Kerman.based on the Gurd criteria,25 of these patients (24 male,1 female) were suffering from fat embolism sundrome(FES).incidence of FES in this study was ...

The distribution, severity, and complications of diet-induced atherosclerosis in dogs can be altered by changing the source of fat in the diet. Thrombosis and thromboembolic disease associated with atherosclerosis occurred with diets containing beef tallow and lard of coconut oil but were absent in dogs fed cottonseed oil as a source of fat. Experiemtnal animals with and without thrombosis are ...

Forty-eight Angus x Hereford yearling steers were used to assess the effect of time on feed (TOF) on the nutrient composition of beef longissimus muscle (LM). Steers were fed a high-concentrate diet with the exception of the d-0 group, which served as a grass-fed control, and then were serially slaughtered at 28-d intervals during the 196-d feeding period. Steaks were removed from the 10th rib ...

Inadequate dietary energy intake and poor body condition can negatively affect reproductive function. Supplemental lipids have been used to increase energy density of the diet and may also have direct positive effects on reproduction in beef cattle. Several fatty acid sources have been studied as they relate to reproductive function. Common sources include sunflower, safflower, cottonseed, rice...

We estimated the genetic parameters related to feed intake (FI), feed efficiency traits (including feed conversion ratio (FCR) and residual feed intake (RFI) of digestible crude protein (DCP) and total digestible nutrients (TDN)), beef marbling score (BMS), melting point of fat (MP) and fatty acid composition. Fat and meat (Musculus trapezius) samples were taken from the carcasses of 863 Japane...

Studies have shown that intramuscular adipogenesis and fibrogenesis may concomitantly occur in skeletal muscle of beef cattle. Thus, we hypothesized that the discrepancy of intramuscular fat content in beef from Nellore and Angus was associated with differences in intramuscular adipogenesis and fibrogenesis during the finishing phase. To test our hypothesis, longissimus muscle samples of Nellor...
