Previous issue date: 2016-06-22 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / The gynecological screening prior to TAI can be considered as a non-invasive technique, relatively simple, safe for the technician and for the animal, and provides quick and extremely important information for the best use of various hormones on the market for use in synchronization protocols of ovulation in cattle. It is important to emphasize the need for gynecological examination before the start of a hormonal protocol because of the risk of causing an abortion or embryonic loss due to prostaglandin that at some point should be administered during the protocol. Additionally, there is the option to choose which the most appropriate hormones to be used in the program, directing the protocols based to animal ovarian physiological status. This screening allows good results enabling the best use of this biotech, making the use of this biotech does not become a cake recipe, i.e. it is not used incorrectly and indiscriminately without criteria. To this end, it has been based on the pattern of cyclicity of the ovaries (presence of corpus luteum, mature follicles or absence of these structures), to increase conception and pregnancy rates by adjusting the protocol to ovarian function. Moreover, we must take into account the ovarian function and also an assessment of body condition score (BCS), along with age and lactation period of the animals before starting the TAI protocol. In this sense, it is very important the knowledge of the technician who will perform synchronization program of estrus and ovulation in bovine females. So that you can successfully execute gynecological and clinical examination of females to be submitted to this treatment. The application of a gynecological screening and carried out by a qualified technician in order to optimize the use of TAI protocols is essential, resulting in cheaper protocols with satisfactory results, in order to make solid and reliable technique / A realiza??o da triagem ginecol?gica previamente ? IATF apresenta-se como uma t?cnica n?o invasiva, relativamente simples, segura para o t?cnico e para o animal, e fornece informa??es r?pidas e extremamente importantes para o melhor uso dos diversos horm?nios dispon?veis no mercado para serem utilizados nos protocolos de sincroniza??o da ovula??o em bovinos. ? importante ressaltar a necessidade do exame ginecol?gico antes do in?cio de um protocolo hormonal devido ao risco de causar abortamento ou mesmo perda embrion?ria em fun??o da prostaglandina e o estradiol que em algum momento dever? ser administrada no decorrer do protocolo. Adicionalmente, tem se a op??o de escolher quais os horm?nios mais apropriados que ser?o utilizados no programa, direcionando os protocolos em fun??o do status fisiol?gico ovariano que o animal se encontra. Essa triagem permite bons resultados viabilizando o melhor emprego desta biot?cnica, evitando o uso da mesma de forma errada e indiscriminada, sem crit?rios. Para tal, basea-se no padr?o de ciclicidade dos ov?rios (presen?a de corpo l?teo, fol?culos maduros ou ainda aus?ncia destas estruturas), para incrementar as taxas de concep??o e de prenhez, ao ajustar o protocolo ? fun??o ovariana. Al?m de levar-se em considera??o a fun??o ovariana, preconiza-se tamb?m uma avalia??o do escore de condi??o corporal (ECC), juntamente com a idade e per?odo lactacional dos animais antes de se iniciar o protocolo. Nesse sentido, torna-se de suma import?ncia o conhecimento do t?cnico que ir? realizar um programa de sincroniza??o do estro e da ovula??o em f?meas bovinas, de maneira que o mesmo consiga executar com sucesso o exame ginecol?gico e cl?nico das f?meas que ser?o submetidas a esse tratamento. ? imprescind?vel a aplica??o de uma triagem ginecol?gica bem realizada por um t?cnico qualificado de maneira a otimizar a utiliza??o dos protocolos de IATF, resultando em protocolos de menor custos e com resultados satisfat?rios, com intuito de tornar a t?cnica vi?vel economicamente e ainda com a previs?o de resultados confi?veis para os produtores
