Twenty-four young Podolian bulls were used to evaluate the effect of rearing system (extensive vs. intensive) in relation to postmortem aging (11 and 18 d) on the eating quality of the meat, with the diet of outdoor animals adjusted to the protein content of the indoor system (15% CP) or to the minimum protein content required for satisfactory growth (12% CP). At 415 ± 9.35 (SE) d of age, with ...

The objective of this study was to investigate the effect distribution chain, distance between abattoir and meat retailer, storage duration at retailer class on physico-chemical quality red meat. Beef (n = 150), pork 150) mutton samples were collected during loading process carcasses into refrigerated trucks, offloading point marketing measure (butcher, middle high class) attributes. Meat attri...

The objective of this study was to determine the levels of catecholamines and their relationship to beef quality in Nguni steers fed on Acacia karroo leaves. A total of 30 19-month-old steers were randomly assigned to A. karroo leaves (AK), sunflower cake (SF) and the control with no supplement (CN) diets. The AK and SF diets provided the steers with an additional 150 g of protein per day for 6...

introduction: nowadays, with the development of imaging systems and image processing algorithms, a new branch of agriculture and food industry quality control has emerged. meat and related products have high commercial value and they are one of the most important items of household food basket (jackman et al., 2011). the apparent color of the meat is one of the most important ranking factors wh...

This study is a meta-analysis of the effects of the beta-agonists zilpaterol hydrochloride (ZH) and ractopamine hydrochloride (RAC) on feedlot performance, carcase characteristics of cattle and Warner Bratzler shear force (WBSF) of muscles. It was conducted to evaluate the effect of the use of these agents on beef production and meat quality and to provide data that would be useful in considera...

this study was conducted to evaluate some postmortem changes parameters (ph, color, rigor mortise and sensory evaluation) in kutum, captured by gillnet and beach seine. eight pieces of kutum were provided from each net and blood was sampled via 5 cc strile syringes from caudal vein and put into special tubes. then, fishes were placed into isolated boxes between thick layers of ice and transferr...

The development of technologies that could be used by the U.S. beef packing industry to accurately characterize beef for tenderness has been a major focus of this laboratory. Because longissimus comprises a higher proportion of total carcass value than any other muscle and there is more carcassto-carcass tenderness variation in longissimus than any other major beef muscle (Shackelford et al., 1...

Meat quality (pH, colour, drip and cooking loss, Warner-Bratzler shear force) and muscle characteristics (lipid and glycogen contents) were compared among two experimental divergent lines of broilers, selected for high abdominal fatness (HF) or low abdominal fatness (LF). By comparison to the LF line, the HF line exhibited a 2.8 fold higher abdominal fat percentage. It also exhibited a slightly...
