A current challenge in genetic improvement of cattle is to identify genomic selection
strategies that could work across breeds. Breed differences, scarcity of data, and lack of …

A putative functional mutation (rs109231213) near PLAG 1 (BTA 14) associated with stature
was studied in beef cattle. Data from 8199 B os taurus, B os indicus and T ropical C …

Age at puberty is an important component of reproductive performance in beef cattle
production systems. Brahman cattle are typically late-pubertal relative to Bos taurus cattle …

A total of 4063 young bulls of two tropical genotypes (1639 Brahman and 2424 Tropical
Composite) raised in northern Australia were evaluated for a comprehensive range of …

Bull fertility is an important target for genetic improvement, and early prediction using genetic
markers is therefore a goal for livestock breeding. We performed genome-wide association …

The primary purpose of spermatozoa is to deliver the paternal DNA to the oocyte at
fertilization. During the complex events of fertilization, if the spermatozoon penetrating the …

Background Twenty-five phenotypes were measured as indicators of bull fertility (1099
Brahman and 1719 Tropical Composite bulls). Measurements included sperm morphology …

Selection for bulls that would reach puberty early reduces the generation interval and
increases fertility and herd productivity. Despite its economic importance, there are few QTL …

Background Previous genome-wide association studies have identified significant regions of
the X chromosome associated with reproductive traits in two Bos indicus-influenced breeds …

Prior to the Co-operative Research Centre for Beef Genetic Technologies (Beef CRC), little
genetic information on bovine male reproductive traits and their associations with …
