The Female Hormones of Reproduction

The Female Hormones of Reproduction

Ropin’ the Web

Hormones are messengers. They are produced and secreted by one part of the body and travel, usually through the bloodstream, to another part of the body to stimulate or depress a particular function. Hormones are the means by which distant parts of the body communicate with each other. Communication disturbances disrupt reproductive function. In the past few years, researchers have discovered that the reproductive hormones are secreted in distinct pulses, a pattern (or code) which varies with the stage of the reproductive cycle. The target tissue, whether h is the ovary, uterus, pituitary or hypothalamus, responds only to specific pattern of hormone secretion that it recognizes. lf the target tissue is unable to recognize the pattern, either due to lack of receptors for the hormone messenger on the target tissue or due to an inappropriate pattern of hormone message, the programmed response does not occur.

In this section, the hormones involved in the regulation of reproductive function in female cattle are presented.

If you’ve written a check to your friendly local animal health supply house or looked at a closeout sheet on a set of high-risk calves, you know sickness reduces profitability. But how much and to what extent it affects your banker’s heartburn might be surprising.

Not only do you have the medicine cost, but sickness reduces average daily gain (ADG), carcass price and gross income, according to Clay Mathis, New Mexico State University Extension livestock specialist.


What Is The Beef Checkoff?

What Is The Beef Checkoff?


The Beef Checkoff Program was established as part of the 1985 Farm Bill. The checkoff assesses $1 per head on the sale of live domestic and imported cattle, in addition to a comparable assessment on imported beef and beef products. The checkoff assessment became mandatory when the program was approved by 79 percent of producers in a 1988 national referendum vote.

The top three producer priorities are herd nutrition, pasture and range, followed by herd health.

Recently, the American Angus Association helped sponsor a survey of commercial cow-calf producers and industry specialists about identifying management priorities. The survey information was gathered and summarized by Tom Field of Colorado State University.

The top three priorities were herd nutrition, pasture and range, followed by herd health. The producer participants actually rated herd health second, but almost first. The industry specialists only rated herd health as their sixth priority, a glaring indication as to who actually owns the cattle.

To ethanol, or not to ethanol, that is the question.

Whether tis better to pay less for a gallon of gas and get less miles per gallon, or to pay more and go further on the same gallon? Tis the question that motorized man has passed down through the ages. Is the perception of being green more important than keeping the price of corn down? It depends on the size of your tank, your tolerance for frequent stops, the coffee at your convenience store, your stock in Chevron or your job at the feedlot.
