Getting The Why On Open Cows
published: September 16th 2010 by: Cory Sullivan source: Boehringer Ingelheim
Open cows can cost cattle producers in fewer calves to sell the next year. When checking cows for pregnancy, it can be disheartening when a percentage of the herd is not pregnant. Confusion over how and why this happened can plague producers, but it is important to come up with a definitive diagnosis to identify these unknowns and prevent the same problem in the future....
Study Shows Effects of Heat Stressed Cows On Follicles
published: September 3rd 2010 by: Robert Burns source: TAMU Ag Communications
Think you're uncomfortable in the extreme Texas summer heat? Try being an ovulating 1,200-pound mother cow. Studies have shown that heat-stressed dairy cows suffer from damage to their ovarian follicles....
Targeting body condition scores of cows at calving
published: September 3rd 2010 by: Sandy Johnson
The body condition of cows after calving can sometimes be surprising. The 150 pounds or so of calf and fluids are gone and it becomes much easier to see the amount of condition, or lack there of, along the back of the cow and over the hooks....
Camp Cooley And Elgin Breeding Service Expand Relationship
published: May 27th 2010 source: Camp Cooley Ranch
Camp Cooley Genetics and Elgin Breeding Service have had a close working relationship for years. We are proud to announce the expansion of that relationship. Effective immediately EBS will be responsible for the semen collection from all of our bulls....
Cattle Pregnancy Affected By Disposition
published: May 11th 2010 by: Dr. Glen Selk source: Oklahoma State University Extension
Now we have another good excuse to cull cows due to bad temperament. Producers that routinely breed cows artificially realize that cows that are unruly and nervous are less likely to conceive to artificial insemination....
Portable Barns For Cattle AI Help
published: April 23rd 2010 source: Missouri Ag Connection
Beef farmers who practice artificial insemination will find that a portable breeding barn makes life a lot easier on both man and beast. "This is especially true if fixed-time AI is practiced and inclement weather hits the day the cows or heifers must be inseminated," said Eldon Cole, livestock specialist with University of Missouri Extension....
Timed Breeding Saves Labor And Improves Genetics
published: April 10th 2010 by: Duane Dailey source: University of Missouri Extension
BOONVILLE, Mo. – The first question was easy after a talk at the Cooper County Cattlemen’s Association meeting. “You mean that if I have a job in town, I can breed all of my cows on one day?” “Yes,” said David Patterson, University of Missouri Extension beef specialist....
Getting Cows Bred After Hard Winter
published: April 7th 2010 by: Dr. W. Dee Whittier, extension veterinar source: Virginia Tech Extension
The winter of 2010 has broken a number of records. Beef cows on most farms have probably been affected to a significant degree by the winter. A review of what research and experience has taught us about reproductive performance helps us predict and hopefully take steps to remedy the effects of this situation on the upcoming breeding season....
Considerations For Breeding Season
published: April 3rd 2010 source: Ag Answers
With the start of the spring breeding season approaching for many producers, a Purdue University animal scientist said there are several aspects to ensuring a successful breeding season. Allen Bridges said that producers should make sure cows and bulls are ready by performing breeding soundness exams, ensuring animals have proper nutrition and evaluating their breeding programs....
Managing Bulls In Multi-Sire Pastures
published: April 2nd 2010 by: Glenn Selk source: Oklahoma State University Extension
Before the breeding season begins, a few simple management procedures involving the bulls can increase the likelihood of a high pregnancy percentage among the cows. In multi-sire pastures, make certain that the bulls that will be pastured together have been in a common trap or pasture prior to the breeding season....
Management Tools Improve Herd Fertility
published: March 5th 2010 by: Tim Hearden source: Capital Press
COTTONWOOD, Calif. -- A few simple management tools can help ranchers maximize the fertility of their bull and cow herds, experts advise. For instance, removing a calf from its mother for a couple of days has been shown to be effective at helping her begin estrus, said Les Anderson, a beef cattle specialist from the University of Kentucky....
Manage Calving Season For Optimal Results
published: January 29th 2010 by: Jerry Little source: AMNews.com
Providing sound management during the calving season can mean more live calves. Excessive losses can mean the difference between a year’s profit or loss for a beef producer. It is important to have a short calving period to allow frequent observation and assistance if needed....
Impact Of Infertility
published: December 16th 2009 by: G. Cliff Lamb, Darl Dahlen, and Mary Mad source: University of Florida
Beef producers need cows to become pregnant, deliver healthy calves, and wean productive calves to make their operations viable. The failure of breeding females to become pregnant directly impacts the economic viability of every beef operation, yet few producers realize how infertility impacts their individual operations....
Know Body Condition Scores For Reproductive Performance
published: December 1st 2009 source: Eli Lilly
Cow-calf operators constantly struggle to find the right balance between optimal body condition scores — which improve conception rates — and keeping feed costs as low as possible. Research has shown the body condition of cows at breeding and calving plays a major role in the length of the postpartum interval and conception rates....
Observe Bulls In First Part Of Breeding Season
published: November 11th 2009 by: Glenn Selk source: Oklahoma State University Extension
The fall breeding season is about to begin. Herds that aim for a September 1 first calving date, will turn bulls with the cows in the latter part of November. A good manager keeps an eye on his bulls during the breeding season to make sure that they are getting the cows bred....
Care Of Newborn Calf
published: October 23rd 2009 by: Glenn Selk source: Oklahoma State University Extension
Delayed passage through the birth canal in the face of a faltering placenta compromises oxygenation of the calf....
Sort Heifers From Cows
published: October 19th 2009 by: Glenn Selk source: Oklahoma State University Extension
First calf heifers have historically been the toughest females on the ranch to get rebred. They are being asked to continue to grow, produce milk, repair the reproductive tract, and have enough stored body energy (fat) to return to heat cycles in a short time frame....
Bulls And BioSecurity
published: October 13th 2009 source: beefcattlesite.com
The purchase of a bull is one of the commonest ways in which disease enters farms. Too many farms think they are closed but buy bulls. A bull is as likely to be infected with an important disease as a cow and, because of the close contact during mating, far more likely to spread it....
Try Preg Testing Sooner
published: October 6th 2009 by: Sara Brown source: Beef Today
Dairy producers preg test cows all the time. Why should cattle producers patiently wait until the cow exhibits signs of being in heat? Every day your cow isn’t bred is a day of loss. If the vet can’t (or in some cases won’t) visit the farm, consider pulling your own blood tests to find those empty cows....
Cow To Bull Ratios For Commercial Herds
published: September 26th 2009 by: Glenn Selk source: Oklahoma State University Extension
The three major goals of any breeding season should be to: get the cows settled as early in the breeding season as possible; get them bred to the bulls with the highest possible genetic worth; and achieve both as economically as possible, by getting the cows bred with the fewest possible bulls....
