DNA polymorphism of introns 1 and 2 of Prolactin Receptor Gene and its association with litter size in goats
Journal Title: Animal Science Papers and Reports - Year 2011, Vol 29, Issue 4
Abstract
The prolactin receptor (PRLR) gene was studied as a candidate gene for the high prolificacy of Jining Grey goats. Polymorphisms in intron 1 and intron 2 of PRLR gene were detected in high prolificacy (Jining Grey) and low prolificacy (Boer, Wendeng dairy, Liaoning Cashmere and Beijing) native goats using PCR-SSCP. For intron 1, five genotypes (AA, AH, AK, HH and HK) were identified in Jining Grey goats, and two (AA and AK) in the other four breeds. The Jining Grey does of genotype HH, HK, AH and AK delivered by 0.65, 0.62, 0.59 and 0.57 more kids (P<0.01) than those of genotype AA, respectively. For intron 2, three genotypes (CC, CD and DD) were detected in Boer goats, and two (CC and CD) in the other four breeds. The Jining Grey does of genotype CD delivered by 0.55 (P<0.01) more kids than those of genotype CC.

Power of different microsatellite panels for paternity analysis in sheep
The aim of this work was to develop and to test PCR-based suitable microsatellite marker panels for paternity testing in sheep. Blood samples were collected from 212 Kivircik sheep (24 rams and their 188 offspring) rais...
Quality of goat pasture in less-favoured areas (LFA) of the Czech Republic and its effect on fatty acid content of goat milk and cheese
The aim of the study was to assess the quality of pastures located in less-favoured areas (LFA) of Czech Republic, to evaluate the influence of that quality on the content of fatty acids of milk in grazing goats and in f...
Association of porcine STIM1 gene with litter size traits
In commercial pig production, litter size has always been one of the most important production traits. Stromal interaction molecule 1 (STIM1) is a transmembrane-spanning Ca2+-binding protein, which is essential for oocyt...
Effect of hCG and intravaginal application of estradiol and prostaglandin E2 on pregnancy rate and litter size in gilts and sows
Three separate experiments were performed on fifty pregnant gilts (Experiment 1 and 2) and forty primiparous sows (Experiment 3) to examine the effect of human chorionic gonadotropin (hCG) administration on day 12 (Exper...
