The growth performance and the carcass and physical and chemical characteristics of the meat of 24 Landrace X Large White pigs were compared when reared under a free-range or a conventional housing system. The free-range pigs had lower feed intakes and slower growth rates than the conventionally housed pigs. The free-range pigs also had a lower P2 fat depth and therefore yielded a carcass with ...

Fifty-four Holstein bulls were blocked by initial BW (301 +/- 7.4 kg) and randomly assigned to 6 treatments following a 3 x 2 factorial arrangement, with 3 concentrate lipid levels (5, 8, and 11% of DM) and 2 lipid sources (whole canola seed and whole linseed), with the objective of evaluating the possibility of increasing the content of n-3 fatty acids in meat. Concentrates (mostly corn meal) ...

The objective of this study was to determine the effect of palm and/or linseed oil (LSO) supplementation on carcass quality, sensory evaluation and fatty acid profile of beef from crossbred Wagyu beef steers. Twenty four fattening Wagyu crossbred beef steers (50% Wagyu), averaging 640±18 kg live weight (LW) and approximately 30 mo old, were stratified and randomly assigned in completely randomi...

This study was aimed to determine the effect of feeding lambs diets with different proportions of double-low rapeseed and linseed and their supplementation with vitamin E on selected parameters of health quality of lamb meat. Lambs were fattened intensively to 30–35 kg body weight with a standard diet and experimental diets containing 10% full-fat rapeseed and linseed at a 2:1 or 1:1 ratio, wit...

Carcass composition and meat quality traits were evaluated in 55 suckling kids (27 males and 28 females) from Serrana (S), Bravia (B) and Serrana×Bravia (S×B) crossbred genotypes. Kids were slaughtered at 8-11kg of live weight according to "Cabrito de Barroso-PGI" specifications and carcasses' left sides were totally dissected. Dressing percentage (based on ELW) did not vary between genotypes a...

This study was designed to compare the quality of veal produced from 'Tudanca×Charolais' cross (n=6) and Limousin (n=6) breeds when allowed to feed freely on mountain pastures and suckle naturally from birth to 7 months of age. After 80 days of age calves also had access to concentrate (maximum of 3 kg/day), while mothers did not. At slaughter, Limousin calves were heavier (P<0.01) and provided...

Genetic parameters for LM fatty acid composition were estimated in Scottish Blackface sheep, previously divergently selected for carcass lean content (LEAN and FAT lines). Furthermore, QTL were identified for the same fatty acids. Fatty acid phenotypic measurements were made on 350 male lambs, at approximately 8 mo of age, and 300 of these lambs were genotyped across candidate regions on chromo...
