Despite our efforts to offer the best product, we are faced with difficult challenges in the country when it comes to climate and soil. The tropical climate, with rainy and dry seasons, ends up greatly damaging the pastures, thus offering less quality nutrients to our herds. As a domino effect, with less nutrients, there is more stress on the animal, which implies a poor reproductive efficiency, which is a crucial factor for effective production. However, there are viable outputs to improve the statistics, and one of them is reducing the interval between calving in cows relating to nutritional aspects, the important theme that the work will address. The nutritional strategy used in the experiment was the supplementation before, during and after the synchronization protocols for IATF. It consisted in the supply of 5g / kg PV / animal / day, a multiple mixture containing 82% ground corn, 8% soybean meal, 4% protected fat (Megalac®), 3% protected urea , 2% calcium carbonate, 0.06% mineral core, 0.04% Sodium Chloride and 0.01% lasalocid sodium 15% (Taurotec®). Supplement delivery started 7 days prior to protocol (D0) and lasted up to 20 after TAI, totaling 38 days. It was observed that the results showed an increase in the pregnancy rate of the primiparas that were supplemented, especially those with ECC below 3 (on the scale of 1 to 5), the percentage variation in the increment was of 2.6 ( ECC ≥3) to 7.1 (ECC = 2.75), presenting lower values in multiparous women. It is evident that, with due planning, observing the moments of nutritional deficit, it is possible to improve the interval between deliveries, thus improving production.</p>}, number={5}, journal={Scientific Electronic Archives}, author={Guse, G.
