Abstract Taste as an eating quality factor of beef can be influenced by the selection raw material and aging method. The metabolic changes different breeds during were analyzed in wet-aged dry-aged up to 28 days using samples from M. longissimus thoracis et lumborum Simmental Black-and-White 1 H NMR spectroscopy. Breed affected metabolome before beef. concentration 24 30 metabolites differed si...

Fat thickness including skin and muscle depth measured on the left carcass side between the second and third from the last rib 70 mm off the dorsal midline were measured in a total of 168 pig hybrid carcasses. The lean meat content was then determined on the basis of simplified dissections of the carcasses. Multiple regressions of the measurements of the fat and muscle thickness on the lean mea...

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...

The increased use of Holstein genetic material in the Irish dairy herd has consequences for beef production. In all, 42 spring-born steers [14 Holsteins (HO), 14 Friesian (FR) and Charolais × Holstein-Friesian (CH)] were reared to slaughter at between 26 37 mo age. Carcass weight was higher lipid concentration m . longissimus thoracis et lumborum lower (P < 0.05) CH than breeds. Overall acce...

This experiment was conducted to investigate the effect of dietary supplementation with green tea extract on growth performance, meat quality and oxidative stability longissimus thoracis et lumborum (LTL) muscle in growing-finishing pigs. A total 16 crossbred pigs, half females males, were randomly assigned 2 treatments. lasted 9 weeks included grower finisher periods. The experimental diets ea...

This review discusses our current understanding of the growth and development of intramuscular fat and proposes a simple growth model to explain the accumulation of intramuscular fat in cattle. Potential effects of nutritional manipulation are discussed in relation to the proposed growth curve for intramuscular fat. The scope for nutritional control during both the pasture (or backgrounding) an...

A 4 × 3 factorial experiment (n=8 pigs per treatment combination) was conducted with 96 female Landrace × Large White pigs to examine the required level of dietary vitamin E and optimum feeding duration before slaughter to maximise muscle vitamin E content in the Longissimus thoracis et lumborum (LTL) muscle. The respective factors were four dietary levels of vitamin E (supplemented as dl-α-toc...

Thirteen Brahman x Shorthorn steers approximately 18 months of age with a mean carcass weight of 190 (a 7.1) kg and a mean fat thickness of 5.8 (+ 1.9) mm at the rump P8 site were subjected to 4 postslaughter treatments. These were: no electrical stimulation or ageing (NIL); electrical stimulation, no ageing (ES); no electrical stimulation, ageing (AGED); electrical stimulation and ageing(ESAGE...
