Publication of this Special Issue, Genetics to Improve Cow Reproductive Performance in Tropical Beef Cattle, represents the culmination of a large, long-term beef cattle genetics research project in northern Australia which was a key initiative of the Beef Cooperative Research Centre (Beef CRC) over two terms. It represented a very significant commitment of scientific and industry resources. The publication continues the close association between Animal Production Science and the Beef CRC in disseminating scientific knowledge of the highest quality to domestic and international audiences.
The papers presented report various aspects of lifetime female reproductive performance in tropical beef genotypes. This follows the previous special issue Genetics and Management to Improve Productivity in Australian Beef Herds, which included five papers from the early years of this project that described the genetics of steer production, heifer growth, adaptation and puberty. The increased understanding achieved across this spectrum of traits is likely to be fundamental to improvements in productivity and whole herd profitability of northern Australian beef cattle production systems.
This special issue will be of particular interest to research scientists, resource managers, agribusiness advisors, as well as farmers, and is essential reading for anyone interested in animal breeding and reproduction.
