Influência de minerais sobre a iatf: Impacto na eficiência reprodutiva de bovinos

Abstract

This study aims to review the literature on the influence of minerals on the pregnancy rate of cows subjected to Fixed-Time Artificial Insemination (FTAI), highlighting their relationships with nutrition, reproductive efficiency, and production system profitability. Therefore, the study is qualitative and bibliographic in nature, based on the analysis of 36 scientific publications, academic projects, and technical manuals published between 2001 and 2025, obtained from platforms such as Google Scholar, SciELO, and the CAPES Portal. Keywords related to mineral nutrition, FTAI, and reproductive efficiency in cattle were used. It was observed that adequate supplementation of minerals such as phosphorus, selenium, zinc, copper, and manganese plays a crucial role in hormonal regulation, ovarian cyclicity, and pregnancy rates. Balanced diets reduce the interval between calvings, increase fertility, and optimize herd productive performance. Conversely, mineral deficiencies or excesses compromise reproductive metabolism and increase production costs. Therefore, strategic nutritional management, combined with proper reproductive management, is essential for the success of FTAI protocols. Balanced nutrition enhances hormonal response and reproductive performance, promoting greater efficiency and economic return for producers.
