Advancing Genomic Selection
Genomic selection supplements the traditional method of genetic evaluation with information on the DNA of an animal to improve the accuracy of identifying genetically elite animals. Noirin McHugh and Donagh Berry from Teagasc say that greater gains can...
Variables That Influence Outcomes Of AI Programmes
Sandy Johnson from K-State Research and Extension looks at what factors can impact a cow's ability to respond with high fertility to synchronisation protocols. ...
Peering At Genes To Detect Origin Of Cattle Diseases
The eyes are said to be the windows into the soul of humans, but in the case of cattle, they may hold clues to overall animal health. A closer look at pinkeye is offering insight into other costly bacterial diseases as well....
Dairy Cow Welfare Strategy 2011 Report
In a move towards improving the welfare of dairy cows, the Dairy Welfare Strategy was created, setting out targets and guidelines for the indusry. The results of the 2011 report have now been published by the Cattle Health and Welfare Group (CHAWG). The...
Processed Crop Residues To Improve Ruminant Performance
This study by Ramana Reddy and G Reddy, from the College of Veterinary Science, India, looks at enhancing ruminant diets through processing crop residues. ...
Systems Of Production For Male Calves From The Dairy Herd

Is Dairy Cow Fertility A Lost Cause?
A sea of change in farmers' attitudes is needed if the problem of poor fertility is to be solved in the modern dairy cow population, says Marco Winters, head of genetics for DairyCo Breeding+, in an article written for Dairy Farmer....
Calving Ease Proofs Rate Sires For Calving Performance
Calving ease proofs will help to reduce calving difficulties and their cost, although the heritability is low....
High And Low Fertility In Dairy Cows
Sean Cumins and Dr Stephen Butler describe a genetic model of high and low fertility in lactating dairy cows. This is a valuable research resource to identify strategies for improving dairy cow reproduction....
Breeding Heifers For Profit
The anticipated expansion in milk production, following the removal of EU Milk Quotas in 2015, will not be achieved without adequate numbers of AI bred, high EBI, early born and well-reared replacement heifers. Now is the time to start breeding the dairy...
Irish Dairy Producers Using Genomically Selected Sires
