Effects of feed intensity and breed on postpartum blood metabolites

Abstract

Introduction: In dairy cows, postpartum negative energy balance impairs fertility. Objective: The aim of this study was to investigate the influence of high and low feed intensity starting one month before first calving on blood metabolites of energy balance in Holstein (H, n=14) and Swedish Red dairy breed (SRB, n=14) kept in a loose housing system. Material and methods: The control group (C, n=12) was fed a diet targeting high production (35kg/day Energy-Corrected Milk, ECM). The lower feeding intensity (L, n=12) was achieved by giving -50% concentrate to target 25kg/day ECM. Blood was sampled every 2 weeks until 2 months postpartum and then once a month until Day 120. Plasma was kept frozen until analysis for glucose, insulin and non-esterified fatty acids (NEFA) concentrations. Data were analyzed with Mixed linear models. Results: For glucose, effects of breed (p
