The next crop of calves is what keeps the cattle industry in business. Knowing this, a Texas A&M University study aims to reduce reproduction failure, which can cause a significant loss to the U.S....
In a recent multicounty webinar series titled “Show Me the Money”, speakers addressed the topic of value and cost of lost pregnancies. Pregnancy rates determined at pregnancy checks are usually higher than number of calves born....
Calving and rebreeding are two sides of a coin; a calf is ultimately the result of a year-round breeding plan for cattle. Simultaneously preparing for beef cattle calving and rebreeding puts you in position to achieve your breeding herd goals: A 365-day calving cycle A tight calving window More and bigger calves How a heifer or cow calves out will impact how quickly she can be rebred....

Maintaining a controlled breeding and calving season can be one of the most important management tools for cow-calf producers. A uniform, heavier, and more valuable calf crop is one key reason for keeping the breeding season short....
For any number of reasons from shortage of pasture to cattle marketing opportunities, knowledge of if and when a cow or heifer is pregnant is valuable.

Natural service has historically been, and continues to be, used in most beef cattle operations; therefore, acceptable bull fertility is critical to the success of these operations....
Biological and economical efficiencies of cow-calf production are largely dependent on successful reproduction. Improvements in reproductive performance can be up to 4-fold more important than improvements in end-product traits in a conventional cow-calf operation selling market calves at weaning....
COLUMBIA, Mo. – A new estrus synchronization protocol evaluated at the University of Missouri greatly improves heat response and pregnancy rates to fixed-time AI in beef cows. MU Extension beef reproduction specialist Jordan Thomas says results from a recent large field trial found 82% of cows come into heat before the timed AI service using the protocol 7 & 7 Synch....
Regardless of the cattle markets, the ability to retain cows in the herd is critical while creating a uniform calf crop. If the heifer was born in the first 21 days, she stayed in the herd 5....
Pregnancy loss is the pits! The high frequency of pregnancy loss in dairy herds is now realized more than ever before and is extremely frustrating.

The Texas A&M AgriLife Extension Service is now accepting applications for the Pregnancy Ultrasound School for sheep and cattle. The school will be held Dec. 5-6 at the Texas A&M AgriLife Research and Extension Center at 7887 U....
Achieving high pregnancy rates is an important goal in every cow-calf operation. After every breeding season, we are either satisfied with the results or wondering why our pregnancy rates were so low and focusing on ways to improve them....
What is the gestation length of a cow? This question usually gets the answer of “it averages 283 days.” A better answer is “it can range from about 265 to as much as 295 days.” For breeds that have focused on low birthweight genetics for several generations, the average gestation length has shortened....
Weather events, poor conditions and hay shortages will result in some cows that will need extra attention prior to and during breeding season. After a weather event, it would be salt in the wound to have cows breed late and fall out of your calving season....
