Fertility is a critically important factor in cattle production because it directly relates to the
ability to produce the offspring necessary to offset costs in production systems. Female …

Advancing the age at which puberty and subsequent sexual maturation is attained in cattle
is central to the reproductive and economic efficiency of both beef and dairy production …

The fertility of young bulls impacts on reproduction rates, farm profit and the rate of genetic
progress in beef herds. Cattle researchers and industry therefore routinely collect data on …

Despite the role of melatonin in the regulation of the sleep-wake cycle and seasonal-
reproduction, the present study investigated, for the first time, the potential role of melatonin …

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 objective of this study was to examine the effect of dietary n-3 polyunsaturated fatty acid
(PUFA) supplementation of rams on semen quality and subsequent sperm function of liquid …

The effect of nutrition during the first and second trimesters of pregnancy in composite beef
heifers on reproductive parameters of their female calves was determined in the present …

Fertility is a key driver of economic profitability in cattle production. A number of studies have
identified genes associated with fertility using genome wide association studies and …

Research into the genetics of whole herd profitability has been a focus of the Beef
