Weekly genetics review: Reflecting on the challenges of the 2019 bull selling season

As the 2019 bull selling season draws to a close, there are some key trends that have emerged from what has been a challenging year for all producers across the country. Despite the continued reduction in cow numbers, this year’s spring bull selling season was not as tough as many producers first feared. Strong sales with high clearances occurred across most breeds in NSW and Victoria, while in the north demand for bulls remained as strong as previous years, with total clearances at major sales…Read More

Weekly genetics review: Are our mature cows becoming too big?

Throughout this year’s drought, one emerging trend has been the topic of mature cow size. There are a number of causes for this trend to develop. Firstly the on-going impact of poor to desperate seasons across Australia has focussed many producers on the nutritional challenges in maintaining larger cows. At the same time, the increased selection of bulls for growth and carcase weight has seen industry question the size of cattle being produced, reports genetics editor Alastair Rayner…Read More

Weekly genetics review: Production systems the focus in new breed indexes

The new Hereford breeding Indexes due for release this month are a big departure on previous indexes, with a focus on production environment and breeding program as the primary drivers and not just finishing system.

Bull selection decisions in the south linked to profit drivers

Be clear on what drives profit in your business and match your bull selection to those profit drivers. That’s the message from MLA genetics program manager Hamish Chandler, who says this should underpin how every producer uses genetic selection tools such as EBVs and indexes.

Weekly genetics review: Relationships that underpin selection

Changing a beef herd, or moving it towards a specific goal is not a quick process. The rate of genetic gain within a herd can be determined by well-proven equations, genetics editor Alastair Rayner reports this week. How quickly new genetics enter a herd and how much selection pressure is placed on existing breeders is the one of the greatest variables when discussing genetic improvement, he says. ..Read More

Weekly genetics review: Defining the drivers behind selection

Selection is a process for all breeding herds. But without a clear focus on the profit drivers – more kilograms of beef per hectare – producers may be overlooking cows that are less profitable in a herd. This makes improvement slower and can impact selection of bulls as there is less chance to really drive the traits that a herd needs, says genetics editor Alastair Rayner..Read More
