    Abstract

    © 2017, University of Zagreb, Facultty of Veterinary Medicine. All rights reserved. The aim of the study was to investigate if feeding with Lactobacillus sakei could be beneficial for dairy cows. For this purpose, twenty mid-lactation cows were randomly allocated into two groups: the control, which received standard food, and the test group, which received standard food with L. sakei supplementation (5.0*108 colony forming units of L. sakei per day) for a two month period. Before and after the experimental period milk production and serum lipid profile (total cholesterol, high density lipoprotein cholesterol, and triglycerides) and oxidative markers (paraoxonase 1, total antioxidant capacity [TA C], total oxidant status [TOS], and oxidative stress index [OSI]) were evaluated. After the experimental period the control group showed very a mild, although significant decrease in serum triglycerides, while in the test group significant decreases in serum total cholesterol and TA C, and increases in triglycerides, TOS, and OSI were observed. The results of the present research indicate that L. sakei supplementation may not be beneficial for dairy cows, as alterations in lipid profile and increased oxidative stress were observed, without any increase in milk production.
