Multiple trait genomic evaluation of conception rate in Holsteins.
A national data set of artificial inseminations in US Holsteins was used to obtain genetic evaluations for conception rate (CR). The objective of this study was to investigate the feasibility and resulting accuracy from using all available phenotypic, pedigree, and genomic information. Evaluations were performed by regular BLUP or by BLUP with the traditional pedigree and genomic relationships ...
متن کاملThe Effects of Post-Mating Administration of Anti-IL-10 and Anti-TGFß on Conception Rates in Mice
Background In fertility studies, it has been shown that transforming growth factor β (TGFβ) and interlukin 10 (IL-10) play very important roles in implantation, maternal immune tolerance, placentation and fetal development, and the release beginning of release for fetal and postnatal death. The present study aims to determine the effects of the postmating administration of neutralizing antibodi...
متن کاملEfficiency of Heatsynch Protocol in Estrous Synchronization, Ovulation and Conception of Dairy Buffaloes (Bubalus bubalis)
The objectives of this study were to test the efficacy of induction of estrus and determine the timing of ovulation in relation to preovulatory LH and estrogen surges in cycling Murrah buffaloes subjected to Heatsynch protocol (GnRH-PGF2α-Estradiol benzoate). In experiment 1, the buffaloes (n = 10) were treated with Heatsynch protocol and observed for estrus and ovulation. In experiment 2 and 3...
متن کاملMolecular Effects of Polymorphism in the 3’UTR of Unc-5 homolog C Associated with Conception Rate in Holsteins
Conception rates among dairy cows in Japan have declined in recent decades. To enhance our understanding of the genes involved in conception rates, we conducted a genome-wide association study (GWAS) using 822 Holsteins and identified a single-nucleotide polymorphism (SNP) associated with conception rate: A+169G in the 3' untranslated region (UTR) of unc-5 homolog C (UNC5C). Cows with higher co...
متن کاملConception rates and related data using frozen dog semen.
There is much interest in the United States and other countries by dog breeders, pet owners, veterinarians and research workers who realize the great potential for the use of frozen semen. This potential is comparable to that already achieved in the cattle breeding industry. Since the first successful pregnancy utilizing frozen dog semen (Seager, 1969), work on aspects of the freezing of dog se...
