Effect of Lactobacilli Symbiotic on Rumen, Blood, Urinary Parameters and Milk Production of Jersey Cattle During Late Pregnancy and Early Lactation

An experiment was conducted to measure the effects of feeding Lactobacilli (LAB) with a slow intake urea supplement (SIUS) blended into a probiotic/prebiotic mixture, fed at pre partum and early postpartum, using 84 Jersey cows. Two integrated diets (ID), pre and postpartum, were fed to two groups of 42 cows: first, pre partum starting 21 d before calving as follows: 1) ID without supplement 2) ID with LAB/SIUS; Second, post calving cows (20 animals each) were fed a lactation diet (LD) T1 with LAB/ SIUS pre and postpartum, T2 LAB/SIUS only prepartum, T3 LAB/SIUS only postpartum and T4 without LAB/SIUS supplementation.
