Improving Beef Cattle Fertility with Genetics

Reproductive performance is a key determinant of profitability in a beef cattle enterprise. Consequently, selection for improved female fertility should be an important consideration for all beef cattle producers.  Read more here

Making Bull Selection Decisions for Heifer Mating

There are numerous factors which need to be considered when selecting a bull to mate over heifers. In many cases, the primary aim of the beef producer is to produce a live calf which is born unassisted, with other economic traits (e.g. growth) of secondary importance.  Read more here

Increasing Pedigree Accuracy with DNA Parent Verification

Accurately recording pedigree information is one of the most fundamental jobs of a beef seedstock producer. Amongst other things, accurate pedigree information is fundamental for the maintenance of an accurate herd book by registered breed societies, it plays a crucial role in enabling the calculation of Estimated Breeding Values (EBVs) from genetic evaluation programs such as BREEDPLAN, and allows seedstock producers to meet their duty of care to provide the most accurate information as possible on their sale animals (e.g. bulls, semen or embryos).  Read more here

Breeding for Polledness

Polledness, or the absence of horns, is an important trait being actively selected for within many beef breeding programs across Australia. Breeding polled cattle provides a permanent solution to many of the problems associated with horned cattle, including easier handling of stock, reduced bruising, reduced risk of injury to stock handlers, reduced labour costs and reduced concerns regarding the animal welfare issues associated with dehorning.  Read more here

A Commerical Producers Basic Guide to using Breedplan information

The purchase of replacement sires in a beef breeding enterprise is a major investment. As a commercial producer not only should you feel confident that the information which you use to make bull purchasing decisions is reliable but also an accurate description of the genetics you will be introducing to your herd. A Bull Breeding Soundness Evaluation (BBSE) test will evaluate a bull’s ability to produce an adequate quantity of good quality semen, desire and capacity to serve females, and a visual assessment can determine both structural soundness and temperament. However it can be very difficult to identify bulls which are genetically superior for traits such as carcass attributes, daughters milking ability and female fertility, when visual differences between bulls are the result of both genetics (which will be passed on to offspring) and environmental effects such as feed regime and age (which will not be passed on to offspring). A way of getting around the problem of identifying what is genetics and what is nutrition and environment is through the use of EBV’s.  Read more here

Perfomance Recording - Getting it Right

The term “rubbish in – rubbish out” is often used when discussing the requirements of performance recording with BREEDPLAN. In other words, the reliability of the Estimated Breeding Values (EBVs) that are produced for the animals in a seedstock herd is a direct reflection of the reliability (or quality) of the information that is submitted to BREEDPLAN.  Read more here
