Gestation Length: Calves Arrive Sooner Than They Used To

published: February 15th 2017 by: Dr. Justin Rhinehart source: University of Tennessee Beef Cattle Extension

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....

It’s no secret that replacement heifers are some of the most valuable animals in your herd; however, value goes hand in hand with vulnerability. With recent record-high costs to develop replacement females, it may be time to consider a refresh on your replacement heifer program....

Looking to save money? It’s foolish to cut preg-checking

published: November 16th 2016 by: W. Mark Hilton, DVM, PAS, DABVP, clinica source: The Ohio State University

As cattle margins tighten, there is a temptation to cut costs to improve profits . . . and I’m all in favor of it if the cost cutting actually makes your beef business stronger. The first place to look at cost cutting is in feed cost, which accounts for around 50% of the total cost of keeping a cow....

Historically, considerable efforts have been made to understand how nutrition impacts health and productivity during the postnatal period.

Diagnosing the failure to breed

published: August 26th 2016 by: Travis Meteer

Open cows are simply a fact of the cattle business. Managing to achieve a 100% pregnancy rate is simply not cost effective, nor should it be your goal. Having a few open cows every year implies some selection pressure is being put on fertility and animals best-fit for your environment....

Ideas on converting to a controlled breeding season

published: August 26th 2016 by: Les Anderson source: University Of Kentucky

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....

Understanding cattle hormones

published: August 9th 2016 by: Dr. Justin Rhinehart source: University of Tennessee Beef Cattle Extension

Benefits to a controlled breeding season

published: August 4th 2016 by: Ryon Walker source: Louisiana State University Extension

published: July 7th 2016 by: Dr. Lew Strickland source: University of Tennessee

I can still hear my daddy now "we need to keep that cow for one more lactation because she is one of our best cows and hopefully we will get a heifer from her." It didn't seem to matter that her udder was broken down and her teats protruded out similar to a hat hanger, we were going to keep her....

published: July 5th 2016 by: Dr. Cliff Lamb source: University of Florida

  Generally, beef herd pregnancy rates after a 60–120-day breeding season tend to range from 80 to 94 percent. Pregnancy diagnosis identifies the 6–20 percent of open cows in the herd so they can be culled after their calves at side are weaned, instead of waiting to the end of the subsequent calving season....

Getting those tricky 2 year olds bred

published: June 22nd 2016 by: Taylor Grussing source: IGrow

Keeping cows in the herd long enough for them to pay for themselves, is often easier said than done especially when brining young cows into the herd each year to replace cull cows. This is because in order to get young females into the brood cow herd, we must first succeed at breeding them back after they have their first calf....
