An experiment was conducted to live the consequences of feeding Lactobacilli (LAB) with a slow intake carbamide supplement (SIUS) integrated into a probiotic/prebiotic mixture, fed at pre partum and early postnatal, exploitation 84 Jersey cows. 2 integrated diets (ID), pre and postnatal, were fed to 2 teams of forty two cows: 1st, pre partum beginning twenty one d before birthing as follows: 1) ID while not supplement 2) ID with LAB/SIUS; Second, post birthing cows (20 animals each) were fed a lactation diet (LD) T1 with LAB/ SIUS pre and postnatal, T2 LAB/SIUS solely prepartum, T3 LAB/SIUS solely postnatal and T4 while not LAB/SIUS supplementation. research lab probiotic supplementation contained close to 4x107 cfu of carboxylic acid microorganism composed of 4x106cfu of Lactobacillum plantarum; 10x106cfu of Lactobacilumdelbrueckii; 8x106cfu L. Helveticas; 10x106cfu Lactococcus lactis; 10x106cfu Leuconostocmesenteroides; and 5x104cfu of Bifidus spp. mixed into a liquid 250g supplement/cow per d in each pre partum and post-partum periods. SIUS composition was: terrorist organization corn, terrorist organization syrup, Sixteen Personality Factor Questionnaire poultry litter, Bastille Day rice sprucing, V-day oilseed meal, 5% lard, four-dimensional feed, 4% salt, 4% urea, 3.2% carbonate, three-dimensional salt, 2.2% ammonia sulphate, 1.6% cement oven mud and I Chronicles mineral salt. DMI, milk yield, and milk macromolecule content were higher for cows receiving the LAB/SIUS probiotics compared with the LAB/SIUS diet.
