A relationship between genotypes at the GH and LEP loci and carcass meat and fat deposition in pigs
TLDR
It is concluded that a knowledge of LEP and GH genotypes might be useful for improving several traits determining carcass quality in some pig breeds and lines.
Differences in piglets sex proportion in litter and in body weight at birth and weaning and fattening results
TLDR
The aim of the study was presentation the differences in piglets sex proportion in litter and its effect weaning and fattening results and it was showed that in litters was born more gilts than boars.
Polymorphism in Coding and Non-coding Regions of the MyoD Gene Family and Meat Quality in Pigs*
TLDR
It may be inferred that mutations in coding and the non-coding regions of MyoD genes exert significant effects on muscle traits related to oxidative metabolism, as well as related to glycolysis and contractile muscle properties, and thereby on meat quality.
Slaughter value and meat quality of the Polish native Złotnicka Spotted pig.
TLDR
The results obtained allow to consider the ZS pig as producer of high-quality meat products and special attention was paid to pH1, meat colour saturation and lightness, the content of muscle pigments, water holding capacity, and frequency of meat defects.
THE EFFECT OF H-FABP GENE POLYMORPHISM ON CARCASS AND MEAT QUALITY IN THE POLISH NATIVE ZŁOTNICKA SPOTTED PIG
TLDR
Values of all analysed traits were within ranges indicating good meat quality of the Polish native Zlotnicka Spotted pigs, and significant relations were found between the polymorphism at locus H-FABP/HinfI and basic chemical meat composition.
Polymorphisms of the osteopontin gene and level of its expression in the reproductive tract of sows / Polimorfizm w genie osteopontyny i poziom jej ekspresji w układzie rozrodczym loch
TLDR
A significant correlation between the OPN genotype and OPN expression (mRNA) level in the ovary, oviduct, uterine body and uterine horn was observed, and real-time PCR analysis to determine the expression dynamics of the ON gene in examined tissues was performed in relation to “housekeeping” genes.
Carcass, meat quality and histochemical traits of m. longissimus lumborum from Złotnicka Spotted pigs and commercial pigs.
TLDR
Findings indicate that both slaughter weight and cold carcass weight were significantly lower, and backfat thickness higher for ZS pigs compared to commercial pigs, while the commercial pigs exhibited longer carcasses and greater area, height and width of the loin eye.
Quality and dietary value of pork meat of the Puławska and Złotnicka Spotted breeds, and commercial fattening pigs
TLDR
In terms of most physicochemical and functional characteristics, meat of native pig breeds was superior to the meat of commercial pigs from mass-production.
Preliminary observations on the effect of calpastatin gene ( CAST ) polymorphism on carcass traits in pigs *
TLDR
It is concluded that CAST gene may be considered as a candidate gene for pig carcass quality and further studies are needed on more numerous animal material covering breeds with all possible genotypes at loci considered.
