Importância do Certificado Andrológico por Pontos na Determinação da Relação touro:vaca e na Taxa de Prenhez em Bovino de Corte

Abstract

Population growth has been occurring gradually in Brazil and around the world, so the world population reached the mark of 8 billion people in 2022. Therefore, global meat production is expected to grow. The Brazilian cattle herd had 234.4 million animals, the second largest in the world, second to India. Despite a significant herd, the reproductive and productive efficiency of the Brazilian herd is still below its real potential. However, beef cattle farming has evolved a lot in recent years and new forms of reproduction are used, but among them natural breeding is still the most widely used. Therefore, there needs to be greater exploration and knowledge of areas that help in the expansion of zootechnical indexes. Thus, animal genetic improvement has been applied in favor of productivity in the livestock system and the selection of bulls in this circumstance ensures an increase in the herd's productivity. To find out the reproductive performance, you can carry out some tests on these animals so that they have the Andrological Certificate by Points (CAP), which in addition to identifying the bull's reproductive merit, indicates the number of females that the said breeder will be able to impregnate in a breeding season. , that is, the bull: cow ratio, where a bull with excellent CAP can impregnate around up to 100 females in a 90-day breeding season. However, this execution decreases over the years. The objective of this work is to carry out a literature review on the importance of the andrological certificate by points in determining the bull: cow ratio and the pregnancy rate in beef cattle.
