Timing of Insemination and Gender

At a recent dairy meeting one of the producers asked if timing of insemination influences the gender of the newly created life. Researchers at the University of Wisconsin-Madison looked into this several years ago and the results are briefly summarized.

Looking to the Future with Precision Dairy Farming

How can robotic milking change dairy farm management and farmer quality of life?   Insights into how European dairy farmers make these technologies work can help US farmers better manage cows using these technologies. 

Improving Ventilation in Dairy Cow Barns

Many health and financial problems associated with increased moisture, odor, and high temperatures can all be greatly reduced by improved ventilation in dairy barns. Increased temperatures are a direct contributor to heat stress. Dairy cows exhibiting heat stress have reduced feed intake, decreased fertility and reduced milk yield. If heat stress is not reduced, major financial losses can ensue.

Heat Abatement for Dry Dairy Cows

In dry cows, heat abatement is important because management practices in the dry period determine the success in the lactation period and the health, growth, and future performance of her calf.

Effects of Heat Stress on Dairy Cattle Reproduction

When heat stress occurs, conception rate can decrease by 53%.  Understanding the causes for this decrease in fertility during heat stress and ways to decrease these effects are discussed in this article.
