NINABANDA, J.J.. Impacto del balance energético negativo en vacas lecheras tratadas con somatotropina recombinante bovina. Rev. vet. [online]. 2018, vol.29, n.1, pp.68-72. ISSN 1669-6840.  http://dx.doi.org/10.30972/vet.2912794.

The objective of the present review was to analyze the productive and reproductive performance of the bovine recombinant somatotropin effect in dairy cows in post-partum period, as well as the impact that occurs with the negative energy balance, on the energetic-protein indicators and gluconeogenic capacity. For which it was necessary to compile the results of the schemes in terms of: alteration of fertility and delaying the ovarian reactivation which results in a first ovulation around the 2 weeks after this point. For the summary of information a methodological investigation was implemented that included: search approaches (negative energy balance and post-partum heat), inclusion approaches (anestrus, follicular development, and bovine recombinant somatotropin) and finally exclusion approaches (live weigh and corporal condition). Many of the authors suggest to value the implications of the hormone in animals that are in the first weeks of nursing, as well as their effect on the corporal metabolism and the milk composition, that impact under the nutritious value and the conditions for the industrialization of the product
