The effect of cystatin B gene (CSTB ) on productive traits in pigs
Journal Title: Animal Science Papers and Reports - Year 2013, Vol 31, Issue 4
Abstract
Cystatin B gene is a candidate gene for carcass and meat quality traits of pigs and belongs to the family 1 of cysteine proteinase inhibitors. The enzyme is a cathepsin inhibitor and the proteolytic cystatin/cathepsin system plays an important role in the growth and development of muscles. Investigations presented here covered 707 pigs from different genetic groups reared in Poland. The aim of this study was to characterise the polymorphism of the CSTB gene identified with restriction endonuclease: Taq I and Pvu II, and to analyse the relation between the CSTB genotypes and carcass traits. All tested animals proved to be monomorphic at the CSTB/Taq I locus . All three possible genotypes were observed with regard to the second CSTB/Pvu II locus . In Polish Large White and Polish Landrace pigs the highest frequency was reported for BB homozygotes. The association between CSTB and carcass traits was found only in Polish Landrace pigs for the meat content of carcass, meat content of valuable cuts and weight of the loin.

Association between IGF1R / i16 / TaqI and IGF1/SnaBI polymorphisms and milk production traits in Polish Holstein-Friesian cows
The insulin-like growth factor (IGF) signalling pathway plays a crucial role in the regulation of growth and development of mammals. The strong mammary insulin-like growth factor receptor type 1 (IGF1R) mRNA expression d...
The effects of diet supplementation with yeast on the expression of selected immune system genes in the milk somatic cells of dairy goats
The aim of the study was to evaluate the impact of diet supplementation with active yeast culture (Saccharomyces cerevisiae) on the expression of selected immune system genes in goat milk somatic cells (MSC) and on milk...
A novel pig gene, CPNE1, differentially expressed in the muscle tissues from Wujin pigs and Large White pigs
The mRNA differential display technique was performed to investigate gene expression differences in the longissimus dorsi muscle from Wujin and Large White pigs. A fragment of one differentially expressed gene was isolat...
Comparison of serological, molecular and cultural diagnostic methods for the detection of Mycoplasma bovis infections in cattle
Previous studies on Mycoplasma bovis in Poland have used serological methods and culture to isolate the causative organism. PCR and PCR/DGGE molecular tests, antigen ELISA, culture, and antibody ELISA methods were evalua...
