Abstract

Objective: Abortion in a dairy herd is a factor that impact the company’s productivity. It is important to provide epidemiological surveillance tools that help anticipate herd reproductive losses in order to correct those through management measures, infectious disease control and proper nutritional management. The analysis of biochemical profiles as a preventive medicine tool is useful to detect metabolic imbalances that can be part of the causality of non-infectious abortions. In this review we analyzed some indicators of the biochemical profile that may reflect metabolic imbalances of energy and/or protein and minerals that may reflect a risk of noninfectious abortion. The use of this tool has allowed to identify the negative energy balance and liver integrity affected by fat mobilization as risk factors for abortion in cows. Also, cholesterol surveillance, as a protection factor, is recommended, and together with body condition score evaluation, would be a useful tool for evaluating energy imbalances in dairy herds.
