Present study explores the effect of hot summer period on the glycolytic rate of early post-mortem meat quality of Ghungroo and Large White Yorkshire (LWY) pig and comparative adaptability to high tem...
The homeobox A11 (HOXA11) gene, a well-known transcriptional regulator, plays a critical role in normal development of the uterus. In this study, the porcine HOXA11 gene, including its promoter region...
Genes that are expressed in skeletal muscles may play a role in prenatal muscle development and postnatal muscle growth and can be considered candidates for economically important traits. Four porcine...
The proportion of variance for service sire was in the range from 2 to 3% (standard error approx. 0.2%) in Czech Large White and 2% (standard error approx. 0.3%) in Czech Landrace for all thr...
Genetic parameters including the proportion of variance for the service sire effect were estimated for number of piglets stillborn (including piglets died until 24 h after birth) and number of pigle...
The mRNA differential display technique was performed to investigate differences in the gene expression in the musculus longissimus from Wujin and Large White pigs. A fragment of one differentially ex...
Data on 75 567 ejaculates from 1 417 boars of the breeds Czech Large White and Czech Landrace collected in 23 AI centres between 2000 and 2007 were analyzed. Fixed effects were estimated from a four-t...
Muscle fibre formation takes place during embryonic development and is regulated by the MyoD gene family, which consists of four genes, MYOD1, myogenin, MYF5 and MRF4. A relationship was studied betwe...
The effect of PvuII polymorphism of the oestrogen receptor gene on litter size and production traits in a Czech Large White population (882 sows, 2 455 litters) was evaluated. Data were analysed by fo...
The use of alternative raw materials like crude glycerine in animal feed to reduce final costs could be of interest as the sector seeks to increase its competitiveness. The aims of the present work we...
This study was conducted to evaluate effects of storage temperatures (4°C and 20°C) and pig breeds (Laiwu pig and Large White pig) on the main antioxidative enzymes (superoxide dismutase, catalase, an...
The aim of the present study was to evaluate the effects of replacing 70% of the protein from fish meal by protein from ensiled or dry cassava leaves and sweet potato vines on the performance and carc...
The subject of research were 40 gilts of Polish Large White breed, which were separatively kept and fed under control. They were slaughtered on 185th day of life. Particular dissection of primary cuts...
The evaluation referred to polymorphism of heterosomes and autosomes and it was based on measuring their areas in the Polish Landrace and Polish Large White breed sows. The average surface area of sex...
The aim of the paper was analysis of changes in range of performance test results of 19782 gilts of Polish Large White conducted in years 1995-2004, produced in Poland in the area activity of Bydgoszc...
