Growth rate, muscle physiology, carcass traits and meat quality in pigs - A collage of studies on pigs at the University of Helsinki
نویسندگان
چکیده
Department of Food Technology/ Meat Technology Section, University of Helsinki, Finland, has focused on interactions between pig (and poultry) physiology and meat quality. The special emphasis in muscle physiology has been put on the effects of growth rate, fibre type distribution, fibre sizes in relation to oxidative capacity, especially carbohydrate metabolism. Also the strength of connective tissue and bones has been studied. In collaboration with Veterinary Physiology, University of Helsinki, the activity of monocarboxylate transporters has also been studied.

The effect of calpastatin polymorphism and its interaction with RYR1 genotypes on carcass and meat quality of crossbred pigs
The aim of the study was to establish the relationship between a calpastatin gene (CAST) polymorphism, the ryanodine receptor gene (RYR1) polymorphism and carcass/meat quality traits in crossbred pigs. No significant differences in the analyzed pigs were found between genotypes CC and CT at the locus RYR1 and CD and DD at the locus CAST/MspI in terms of carcass and meat quality. However, a sign...
متن کاملWithin-litter variation in muscle fiber characteristics, pig performance, and meat quality traits.
The objective of this study was to examine the intralitter variation in postnatal growth performance, meat quality, and muscle fiber characteristics when littermates were categorized by carcass weight. Thirty-nine litters were weaned at 4 wk of age and had free access to feed from 2 wk of age until slaughter. They were slaughtered by litter at an average BW of 104 +/- 14 kg, and six pigs per li...
متن کاملAssociation of Insulin-like growth factor binding protein 2 genotypes with growth, carcass and meat quality traits in pigs
BACKGROUND This study was conducted to investigate the potential association of variation in the insulin-like growth factor binding protein 2 (IGFBP2) gene with growth, carcass and meat quality traits in pigs. IGFBP2 is a member of the insulin-like growth factor binding protein family that is involved in regulating growth, and it maps to a region of pig chromosome 15 containing significant quan...
متن کاملGenome-wide mapping and identification of new quantitative trait loci affecting meat production, meat quality, and carcass traits within a Duroc purebred population.
Most QTL detection studies in pigs have been carried out in experimental F(2) populations. However, segregation of a QTL must be confirmed within a purebred population for successful implementation of marker-assisted selection. Previously, QTL for meat quality and carcass traits were detected on SSC 7 in a Duroc purebred population. The objectives of the present study were to carry out a whole-...
متن کاملCorrelative responses for carcass and meat quality traits to selection for ovulation rate or prenatal survival in French Large White pigs.
Correlated effects of selection for components of litter size on carcass and meat quality traits were estimated using data from 3 lines of pigs derived from the same Large White base population. Two lines were selected for 6 generations on high ovulation rate at puberty (OR) or high prenatal survival corrected for ovulation rate in the first 2 parities (PS). The third line was an unselected con...
