In all the hoop-la over Fonterra's plan to bring in outside investment an announcement that could have as big an impact, if not more so, on the future of dairying has been barely noticed. It is a statement from farmer-owned dairy genetics company LIC that it will try the new technique of sexing semen. This allows farmers to choose to produce either female or male calves. Obviously, in an industry that runs on milk, more females are desired. The process that LIC - formerly known...

The greatest problem facing the dairy industry today, at primary production level, is the continuing decline in cow fertility. Low fertility leads to reduced milk yields, increased labour and veterinary costs, increased culling of cows due to failure to become pregnant and the resultant loss of income to dairy farmers. It is also implicated in the decreasing competitiveness of the Irish dairy industry, which results in increased numbers of people leaving dairy farming with negative...

The percentage of stillbirths has been steadily increasing but you can take steps to improve that rate on your farm. You'll soon be able to improve the chances of having a live calf on the ground-especially from a first-calf heifer-by looking closely at bull proofs for calf survival rates due to be published in early 2008. Recent numbers suggest that stillbirths have been rising for Canadian Holsteins, although the reasons still aren't clear. Canadian Dairy Network statistics...

Dairy producers need to be aware of the cost of raising replacement heifers and find ways to reduce those costs. All our discussions so far have focused on dairy cows, but what about heifers? They eat, too! The costs of raising dairy heifer replacements represent 20 percent to 25 percent of the total costs of milk production. Benchmarks for the economics of raising dairy heifers, whether custom or home raised, provide opportunities for application to individual farm...

A nutraceutical is defined as a product isolated or purified from feeds that is demonstrated to have a physiological benefit or provide protection against chronic disease. Indeed selenium (Se) is an essential nutrient in that selenium deficiency is associated with increased incidences of retained fetal membranes, clinical mastitis, calf mortality and increased milk somatic cell counts (SCC). Selenium supplementation in Se-deficient diets reduces the incidence of these clinical...

It was a little rancher know-how and access to the world's best feed that put Alberta beef on the map. Now, University of Alberta researchers are not only putting beef on a map of a different kind, they're building it. Stephen Moore, head of the Bovine Genome Program in the Department of Agricultural, Food and Nutritional Science, has led a U of A contingent in helping to complete a biological map that is critical for the sequencing of the bovine genome. It is hoped this physical...

Over the last three decades, our emphasis in ration formulation has shifted from only milk volume and fat to include milk protein percentage and yield. In recent years more precise mathematical approaches have now allowed us to improve models of nutrient use tremendously. They will be used more frequently in the future for support of decisions not only on the nutrition of cattle, but for other aspects including farm economics and environmental impact. Feeding management has...
