Optimal sperm production is achieved if the temperature of the testes is maintained a level below normal body temperature. Domesticated animals[ edit ] Traditionally, farmers have discovered that the most economically efficient community of animals will have a large number of females and a very small number of males. Thus the risks increase as efficiency of bull utilization increases. In cows in which estrous synchronization is used, the recommendations are altered by necessity. Under these conditions, seminal quality is not an issue, and differences in libido are expressed due to the large number of females that are to be serviced. Transverse processes can be felt with firm pressure; processes appear smooth; the overhanging shelf effect is not noticeable. Unfortunately, by the time a sire has demonstrated his potential, he has often outlived his usefulness from a genetic standpoint for a given operation. For more information, visit www. I will only briefly highlight a few of these factors here to emphasize their importance in determining mating capacity of bulls. The variations cited above for the effects of libido on herd fertility can be explained as follows. Rather, the mating capacity of an individual bull is more important to reproductive success than the bull: Virgin bulls often require a learning period, and perhaps an offered sexual experience in order for them to demonstrate their true potential for libido. Thus, careful consideration is necessary for evaluation of seminal quality of young bulls, and to the challenges we subject them to in terms of bull: It may not be necessary or practical to palpate all cows under most circumstances but an understanding of the scoring system and what is involved would allow eye-balling or visual appraisal of cows to evaluate condition. The largest effects of libido score on herd fertility can be detected when one compares bulls of different libido scores that have equal BSE scores i. The following graph illustrates how difficult it is for producers to know what the optimum cow to bull ratio should be.

  1. In the typical situation in which a formal libido score is not available the only other viable option is through observation of the willingness and competence of the bull when exposed to females in heat. The same reasoning holds if females are substituted for males throughout. Bull overlap more than one bull breeding a cow in heat is not desirable, primarily because it does not enhance pregnancy rates.

  2. Importantly, in a study of 1, calves produced from sexed sperm, there were no excess problems in resulting calves compared to calves produced with unsexed sperm. Bacteria of the genus Wolbachia cause skewed sex ratios in some arthropod species as they kill males.
