Optimizing fertility on dairy farms is necessary and challenging on today’s dairy farms.
Visit Dr. Paul Fricke’s: Extension Program in Dairy Cattle Reproduction
The goal of Dr. Paul Fricke’s extension program is to improve 21-day pregnancy rates by applying knowledge gained through scientific research to develop practical management strategies and assess new reproductive technologies, and to disseminate that information throughout Wisconsin, the U.S. and the world.
Reproductive data is particularly difficult to measure which makes it a challenge to measure and monitor, even on large dairy farms. Measuring reproductive performance is about measuring probabilities—the likelihood an event will occur.
Heifers represent the future of the dairy operation, bringing genetic progress to the milking herd. Raising heifers is costly and improving efficiencies in raising them can have a financial impact on the overall profitability of the dairy business.
In 2019 Cargill conducted a Feed4Thought survey of consumers from the United States, China, Mexico, and Spain. In this survey, they asked consumers to identify the word that best described what they wanted a farmer to be. The survey showed 30% of respondents wanted farmers to be “sustainable.” The second most-used word to describe what […]
Raising replacement heifers is a large investment for farmers to create the next generation for their herd. The cost of raising a replacement heifer on average is $2,500 with feed accounting for approximately 50% of the total rearing cost.1,2 The average age at first calving (AFC) has been decreasing in the United States because farmers […]
There are three stages to the birthing process, or parturition: dilation of the cervix, delivery of the calf, and delivery of the placenta. Knowing the normal birth process will help you decide whether or not to intervene.
Picking animals for your farm is one of the most important decisions you can make to improve long-term profitability. Whether it is choosing replacements, or deciding who will become parents, without proper consideration the decisions could end up giving you the genetics you did not want.
Heat stress not only affects the productive ability of your cattle but also their ability to conceive and sustain a pregnancy. It is important to understand the effect heat stress can have on reproduction and how you can help minimize the effect.
