INDUÇÃO DE PUBERDADE EM NOVILHAS BOVINAS – REVISÃO DE LITERATURA

Abstract

Proper reproductive management is undoubtedly one of the most important aspects of animal production that directly impacts herd productivity indicators. In Brazil, in general, nulliparous females tend to be late in terms of age at puberty and age at first calving, causing a reduction in the economic / financial return in this sector. Faced with this situation, interest in strategies that improve their reproductive efficiency has grown. In order to optimize the reproductive results of heifers, puberty induction has been sought, which consists of the use of nutritional adjustments and bio stimulation methods, as well as pharmacological protocols with the aim of anticipating the cyclist of females. The objective of this literature review was to discuss the induction of puberty in bovine heifers, listing the main protocols used. In view of this, it is concluded that the use of puberty anticipation methods in heifers, whether bio stimulation, nutritional management for weight gain or induction through the association of hormones, are efficient in inducing puberty in bovine heifers.
