COWBOY WISDOM No 43 Whorling Fertility Most of the articles Steve and I have published the past year have been teaching about reproduction in both the cow and bull. Our primary emphases has been about the very low semen quality of the bull. Temple Grandin, in her research (see this link), found that when there is skin showing in the face star (Pineal whorl at its worst will look like a gash) the bull has a lower quality of semen. Low quality semen, with abnormal sperm cells above 8%, leaves cows open. When the semen volume is below 1 billion cells on a matured bull he runs out of sperm cells and lowered libido, he fails to bred and/or leaves cows open. I managed my own bull stud for 25 years. Bulls are not something new to me. I dealt with many of the issues we have talked about. Steve and I have also found the bulls with skin showing or a part in the star of the bulls face represents irregular shaped testicles. Irregular shaped testicles (scrotal) never have high quality and quantity semen. Numbers of cells are lower than required, abnorms are higher than acceptable for high quality semen and, as a result, he will leave cows open. Bulls developed on grain will have a diminished ability to produce semen and the abnorms will be higher. You may be wondering why we make this statement. The scrotum is a thermo-regulatory system. If you line and fill that scrotum with fat the temperature remains abnormally high and the volume decreases by the percentage of factory that is taken up by fat cells. This results in lower total sperm and the abnorms go up because they were all made in an abnormally warm factory. I have 4 different research papers that have been released in the past year that show that Universities are beginning to discover what Steve and I have been teaching the past 12 years about herd bull fertility. You must remember that Dr. Jan Bonsma and James Drayson, through their research, discovered that using bulls with abnormal testicles (hypo-plastic or incomplete gland development) is a genetic problem and is passed on to the daughter and sons generated with these structural defects. Our desire is for you to know the practical parts that are the most important selection traits when buying a herd bull or having a semen quality test. You need to set your standards and not some practitioner. It is your money and your future. Please dont settle for industry standards that fall below high reproduction criteria. In the next two weeks. will be including more research that the university system has found. You must remember they most likely wont ever have the whole picture of reproduction and neither do I. However, because you and I depend on this for our way of life and lively-hood and lay awake at night wondering what could you/I do to be better, we can understand a different set of values. Believe me God did not make livestock breeding and management a complicated occupation, praise Him and thank Him.
