Using Male Performance to Improve Genomic Selection for Female Fertility in Brahman Cattle
نویسندگان
چکیده
Genomic selection offers the opportunity to improve female fertility in the Northern Australian beef herd. However, genomic predictions for a number of female fertility traits derived solely from the small number of female fertility records collected thus far are only of modest accuracy. In this study measures of Brahman male reproduction were used jointly with the female records, increasing the accuracy of genomic predictions for Brahman female fertility. Scrotal circumference measured at 18 months was found to be the most useful to increase accuracies of cow GEBVs for a range of traits upto 22%.

A genetic marker is a gene or DNA sequence with known localization on a chromosome. It can be de-scribed as a variation that can be measured or detected by a suitable method, and can be used subsequently to detect the presence of a specific genotype. Such variations occurring at chromosomal or DNA level can serve as genetic markers. The progress in development of molecular markers suggests thei...
متن کاملSelection to Improve Performance of Cattle in Subtropical Regions Using Heat Tolerance EPD
Subtropical regions such as the South-Eastern United States as well as places like Brazil are characterized by average year round temperatures of 27 ̊C (80°F). In the summer months temperatures can rise to 43°C (110°F). These temperatures are usually associated with high humidity and low forage quality and it is imperative that beef cattle in these regions be able to withstand these warm, harsh ...

The reproductive performance of bulls has a high impact on the beef cattle industry. Scrotal circumference (SC) is the most recorded reproductive trait in beef herds, and is used as a major selection criterion to improve precocity and fertility. The characterization of genomic regions affecting SC can contribute to the identification of diagnostic markers for reproductive performance and uncove...
