10Particularities of Bovine Artificial InseminationAntônio Nelson Lima da Costa, Airton Alencar de Araujoand José Valmir FeitosaFederal University of CearaBrazil1. IntroductionIn beef production systems a good reproductive performance is essential for the efficientmanagement and production. The production of cattle can be divided into two sectors: dairyand meat production. In many European countries and developing countries, even the cattleis used as a source of meat and milk and are called dual fitness. Unlike in countries such asAustralia, Brazil and the United States, the functions of production of meat and milk wereseparated and the creation of selective breeding is directed to a single feature.The productive and reproductive performance of cattle herd is directly related to the serviceperiod, calving interval, number of service per conception and number of calves weaned.Artificial insemination (AI) has been proven worldwide and has proven to be a viabletechnical and economical to increase the genetic gain and increase efficiency, especially inproduction systems for meat and milk.In cattle, AI despite presenting a series of known proven advantages, gradually beingreplaced by fixed-time artificial insemination (FTAI) because of lack of skilled labor,logistical problems in large AI programs, in failures detection of estrus; costs forimplementing the program, no optimization of herd reproductive efficiency, and thedifficulty of practical application in field conditions.In this chapter discuss techniques to improve conception rates using artificial insemination,such as: improved detection of estrus, a reduction in calving interval, implementation ofFTAI; calving and breeding seasons, care with the semen, body condition score of females,the female gynecological evaluation, diagnosis of pregnancy, parturition rate.After the reading of these topics, many barriers bovine artificial insemination will beelucidated, and the artificial insemination technique is best applied in various conditions ofmanagement of cattle herds worldwide.2. Improvement in detection of estrusWorldwide there are reports that indicate low rates of service in artificially inseminatedcattle, mainly due to problems in the detection of estrus. While few cows are detected inheat losses occur in significant herd reproductive efficiency, and commitment of the artificialinsemination program. This commitment is even higher in Bos indicus cattle, whose breedingbehavior has special features - heat of short duration with a high percentage of expressionduring the night (Galina et al., 1996, Pinheiro et al., 1998). This feature was confirmed with
