The experiment was performed in Carchi province, Ecuador, during the rainy season. Two groups of 16 animals each were randomly formed. The same foods were supplied to all, and those in the treated group were supplemented with corn, in an amount of 1.0 kg DM, 30 days before parturition, and 2.0 kg DM at the beginning of lactation until 60 days postpartum, plus parenteral supplementation of 20 mL of kyrofosfan.The hematochemical parameters and reproductive indicators were determined, which were compared by t- Student test for independent samples. The contributions of Cu and Zn did not cover the requirements in both study groups. The metabolizable energy was deficient in the animals that were not supplemented with corn. In the cows from the treated group, the concentrations in blood serum of P, Cu, Zn and cholesterol, and the body condition were higher (P <0.05) at 30 and 60 days postpartum. Total proteins increased (P <0.05) at 60 days postpartum, while betehydroxybutyrate decreased (P <0.01) at 30 days postpartum.The supplementation decreased (P <0.05) the parturition-first service interval, the services per gestation (P <0.001) and the parturition-conception and parturition-parturition intervals. It is concluded that energy-mineral supplementation improves the metabolic profile and reproductive indicators. 2021 artículo científico 0864-0408 https://www.redalyc.org/articulo.oa?id=653769345006 https://www.redalyc.org/journal/6537/653769345006/ https://www.redalyc.org/journal/6537/653769345006/html/ https://www.redalyc.org/journal/6537/653769345006/653769345006.epub https://www.redalyc.org/journal/6537/653769345006/movil en http://www.redalyc.org/revista.oa?id=6537 Cuban Journal of Agricultural Science application/pdf Instituto de Ciencia Animal Cuban Journal of Agricultural Science (Cuba) Num.2 Vol.55 |
