health group (HG) categories for analysis. Blood analytes were analyzed by ANOVA with main effects of period, HG and their interaction with herd as a covariate. Herds ranged in size from 100 to 750 cows with Holstein and Simmental being the predominate breeds. A total of 40 metabolic profiles were performed. Herds were categorized into HG of no problems (NP, n=6), heat stress (HS, n=6), fresh cow diseases (FD, n=16), low production (LP, n=5) and other diseases (OD, n=7). Time period influenced (P

Morgante 1 1 Universita’degli Studi di Padova, Dipartimento di Scienze Cliniche Veterinarie, Legnaro (PD), Italy 2 Istituto Zooprofilattico Sperimentale delle Venezie, Legnaro (PD), Italy Milk fever represent one of the most important economic losses in dairy cows management, therefore to found some indicators (blood parameters or functional test) before calving should be very important for the prevention of hypocalcaemia and related disorders. The objective of this work was to study some blood and urinary excretion parameters during late pregnancy that could be related with the calcium status after parturition. 60 dairy cows from a farm located in the North of Italy with high incidence of milk fever were monitored 7 (±2) days before calving and 24h after calving: blood and urine samples were simultaneously collected for creatinine (Cr), calcium (Ca), phosphorus (P), magnesium (Mg), sodium (Na) and potassium (K) determination. Fractional excretion (%CrX) of electrolytes were calculated by the following formula: %CrX = Xu/Xp x Crp/Cru x 100 where “u” and “p” were the urinary and plasmatic concentration, respectively. Results were subject to ANOVA and correlation analysis using SIGMA STAT 3.05. Blood level of Ca after parturition show only a significant (P < 0.05) correlation (+ 0.490) with the blood level of Mg during late pregnancy but the results indicated that there were several significant correlation between the urinary level of Ca after parturition and some parameters during late pregnancy: in particular with the blood level of P (+ 0.378), with the urinary level of Ca (+ 0.384), P (+ 0.401) and Mg (+ 0.277) and with the fractional excretion of Ca (+ 0.360) and P (+ 0.374). These data suggest that modifications of some blood and urinary parameters during late pregnancy could be related with the calcium metabolism after parturition. Although no animal developed any hypocalcaemia status post partum, this data suggest that it could be very important to do further studies especially on Ca and P excretion before calving to found useful indicators for risk evaluation of single cows regarding the probability to develop hypocalcaemia and related disorders after parturition. 481 Effect of Glycerol-containing Preparation on Changes in Selected Parameters of Dairy Cows in Experimental and Field Conditions Z.

Kovac 1 1 University of Veterinary Medicine, Department of Internal Medicine, Kosice, Slovakia 2 Polychem s r. o., polychem, Prievidza, Slovakia The aim of our study was to determine the effects of glycerol-containing preparation on changes in selected parameters in rumen fluid (volatile fatty acids - VFA, acidity - pH), blood serum (glucose, total cholesterol - TCH, total lipids - TL, triglycerides - TG, nonesterified fatty acid - NEFA, betahydroxybutyrate - BHB), and milk (fat, protein, urea) of dairy cows. The observation was aimed at prevention of lipomobilisation syndrome of cows during peri-partal period. In experimental conditions we determined optimal dose of glycerol from three selected concentrations. We used 150, 200, 300 g/day/cow in 24 dairy cows. In the third experimental group (300g) the positive effects were recorded. The following observations were done in herd of 210 Holstein-Friesian dairy cows kept in loose housing with annual milk yield of 8500L. Glycerol bound to powder vehicle was added to the diet at the dose of 320g per animal and day for 35 days (3 weeks before and 3 weeks after parturition). To compare glycerol effects on health and production, 12 experimental cows were selected and divided retrospectively by date of calving into two groups E1 (n = 6) and E2 (n = 6), and by the period of glycerol intake before and after parturition (E1
