The Impact of Hot Weather on Bull Fertility

The Impact of Hot Weather on Bull Fertility

By Glenn Selk

Several research trials have been conducted throughout the years looking at the effect of high temperatures on bull fertility. Certainly that research has importance to many Oklahoma and Southern Plains cattlemen in the summer of 2006. As far back as 1963, researchers exposed bulls to temperatures of 104 degrees F. and 54% humidity for an 8 period and then allowed the temperature to drop to 82 degrees F with 72% humidity for the remainder of the 24 hour period. This temperature regimen was continued for 7 days and was designed to resemble natural conditions in the subtropics. They found the high temperatures resulted in major detrimental effects on initial sperm motility, sperm concentration and total numbers of sperm per ejaculate.

More recently (1978), Oklahoma scientists (Meyerhoeffer, et al.) placed bulls in controlled environments of 95 degrees F. for 8 hours and 87 degrees for the remaining 16 hours while similar bulls were placed in environments of 73 degrees constantly. These treatments were applied to the bulls for 8 weeks and then all bulls were allowed to be in the 73 degree environment for another 8 weeks. During the treatment, the heat stressed bulls had rectal temperatures of 101.7 degrees F and non-stressed bulls had rectal temperatures of 100.8 degrees F. The percentage of motile sperm cells decreased significantly in the stressed bulls by 2 weeks of heat stress. Sperm motility continued to decrease until the heat stress was removed. However, sperm motility did NOT return to normal values until 8 weeks after the end of the heat stress. This explains some of the reduction in fertility that is often associated with summer and early fall breedings. One cannot escape the conclusion that high ambient temperatures can result in detrimental effects on fertility by effects on both the cow and the bull.

Adjust Sights To Aim for High-Quality Beef

Adjust Sights To Aim for High-Quality Beef

Angus e-List

A tenth of an inch can’t make much difference.

Try telling that to an Olympic silver medalist who missed the gold by a hair’s breadth, or to a heart surgeon, a machinist or a bomb squad leader. Try feeding cattle and missing the grid premium because of smidgen too much, or too little, fat on a steer. There’s a feeling of regret — so near and yet so far.

Cattle feeders often sell finished animals based on estimated fat cover. They also keep an eye on the markets and adjust days on feed for genetics or source of cattle if they know those things. Mainly, they look for indicators that back fat is starting to pile on faster than muscling.

Traditionally, the estimated fat thickness that says it’s time to sell has been 0.4 inch (in.). But the beef industry keeps discovering more reasons to manage by cattle type and product target. New evidence suggests the 0.4-in. rule falls short if cattle have the potential to hit high-quality beef targets.

High Plains Journal

OMAHA (DTN) — Talks Friday between USDA officials and Japanese meat inspectors went well enough that a top USDA official said he was comfortable Japanese officials will soon announce they are ready to start importing U.S. beef.

Chuck Lambert, deputy undersecretary for marketing and regulatory programs, said he anticipated Japanese audit teams will return home and complete a report that will allow Japanese political leaders to make a final decision.


Beef producers could help local economy

Hundreds of beef farmers from around the region attended a beef conference in Marion, Virginia sponsored by Congressman Rick Boucher. The farmers listened as Food City President, Steve Smith and others in the farming industry talked about what they believe is a better way to raise beef cattle.
“We think there is a niche for the natural grass fed beef, which has many health benefits,” Smith said.


Time to take a hard line on trade

Farm and Ranch Guide

“Trust, but verify” is a timeless bit of advice made famous by President Reagan in the early 1980s when he dealt with foreign governments in military negotiations. It also strikes me as being very appropriate in trade negotiations, especially after 2 1/2 years of arm-wrestling over the re-opening of key markets to U.S. beef.

New Iowa State–Nebraska program addresses national shortage of food animal veterinarians

AMES, Iowa and LINCOLN, Neb.– Officials at Iowa State University and the University of Nebraska–Lincoln have approved an agreement that will bring the nation’s two leading livestock producing states together in addressing the region’s increasing need for veterinarians.


Purdue Outlook: Cattle Industry Faces Vulnerable Period

Purdue Outlook: Cattle Industry Faces Vulnerable Period


Cattle producers are continuing a slow expansion of brood cow numbers, but rapid movement of calves into feedlots due to depleted pastures means lower finished cattle prices are likely. Late 2006 and early 2007 remains a vulnerable period for the cattle industry as higher beef supplies are interfacing with delays in restoring beef exports to Asia. Slowing U.S. economic growth in the face of rising energy costs may also reduce beef expenditures.



Japan may partially lift its ban on U.S. beef this week, reports say.


Japan is expected to partially resume imports of U.S. beef this week, according to two national (Japan) news sources–Kyodo News Agency and the Mainichi newspaper. If the sources are correct, the Japanese government will officially approve the resumption of beef trade with the United States by the end of the week.

And the heat hangs on.

Each summer leaves its mark. This year it is the mark of heat. The grass is drying, the crops are dying and the cattle are starting to roam. If it wasn’t for flies, the herds would be more dispersed, but the constant irritation tends to force the herds to congregate for some relief.

The point still remains – the pastures are dry. So what should a producer do?


Anthrax Risk High For South Dakota Livestock

Anthrax Risk High For South Dakota Livestock


The drought has forced hundreds of KELOLAND ranchers to sell their herds. Now, hundreds more are taking extra steps to keep their livestock alive.

The drought has made the spread of the anthrax spores easier. Animals are grazing closer to the ground and eating more dirt with the grass. And that’s where the spores are usually found. Now, many ranchers are worried South Dakota is on the verge on an anthrax outbreak. Anthrax spores can lay dormant in dirt for decades, and now dry conditions are putting more KELOLAND livestock at risk for the illness.

“We’re on pins and needles waiting for it to break, and watching it very closely,” said Veterinarian Steve Tornberg.
