Vaccination of boars with a GnRH vaccine (Improvac) eliminates boar taint and increases growth performance.
TLDR
The vaccine was well tolerated by the pigs, and no observable site reactions could be detected at the time of slaughter, and vaccination of boars with Improvac allows production of heavy boar with improved meat quality through prevention and control of boar taint. Expand
Effects of dietary factors and other metabolic modifiers on quality and nutritional value of meat.
TLDR
A number of technologies that increase feed efficiency and lean tissue deposition while decreasing fat deposition have been developed in an effort to improve profitability of animal production and the aim of this review is to collate data on the effects of these metabolic modifiers on meat quality, and then discuss these overall effects. Expand
Dietary conjugated linoleic acids increase lean tissue and decrease fat deposition in growing pigs.
TLDR
Overall, dietary CLA increased the gain to feed ratio and lean tissue deposition and decreased fat deposition in finisher pigs and was maximized at 5.0 g/kg dietary CLA. Expand
The effect of dietary magnesium aspartate supplementation on pork quality.
TLDR
Comparison of meat quality traits indicates that MgAsp supplementation to pigs raised the muscle pH in the LT muscle at 40 min and 24 h after slaughter and can significantly improve ultimate meat quality and reduce the incidence of PSE meat. Expand
The effects of immuno- and surgical-castration on the behaviour and consequently growth of group-housed, male finisher pigs
TLDR
Castration reduced social behaviour and increased feeding behaviour in group-housed entire and castrated male pigs during the finisher stage of production, and the results of the experiment suggest that the social and feeding behaviours of immuno-castrated males at 21 weeks were similar to surgically- castrated males. Expand
Reducing the length of time between slaughter and the secondary gonadotropin-releasing factor immunization improves growth performance and clears boar taint compounds in male finishing pigs.
TLDR
The study provides further evidence of the efficacy of the anti-GnRF immunization and indicates that the secondary immunization can be moved closer to slaughter, while still limiting the incidence of boar taint. Expand
Ractopamine hydrochloride improves growth performance and carcass composition in immunocastrated boars, intact boars, and gilts.
TLDR
Dietary ractopamine may decrease fat mass in intact and immunocastrated boars and offers an excellent means of maximizing the effects of immunocastsration and minimizing the increase in fat mass sometimes observed in immunocasting boars. Expand
Effects of nutrition and management on the production and composition of milk fat and protein: a review
TLDR
Research into targetted feeding strategies that make use of feed supplements including oil seeds, vegetable and fish oils, and organic Se supplements would increase the management options available to dairy farmers for the production of milks that differ in their composition. Expand
Age, sex, and weight at weaning influence organ weight and gastrointestinal development of weanling pigs
TLDR
The data suggest that pigs wean at 2 weeks of age and pigs weaned light-for-age at either 2 or 4 weeks have a less developed gastrointestinal tract, and that its development after weaning might proceed differently to that of pigs weaning older and heavier. Expand
Intracerebroventricular infusion of leptin elevates the secretion of luteinising hormone without affecting food intake in long-term food-restricted sheep, but increases growth hormone irrespective of
TLDR
The treatment of leptin was not sufficient to reduce plasma GH levels in the food-restricted animals, suggesting that other factors or mechanisms must be involved in the regulation of this axis. Expand
