541 Variability of Blood Profile and Milk Composition in Relation to Stage of Lactation and Season of the Year in Dairy Cows SM. Abdel raheem, C. Iben University of Veterinary Medicine Vienna, Nutrition, Vienna, Austria Objectives of study: The study was designed to determine the seasonal and lactational influences on blood metabolites, milk composition, BCS, and back fat thickness (BFT) in dairy cows. Materials and methods: The study was conducted from April 2006 until February 2007 using (n=35) dairy cows (27 Fleckvieh and 8 Holstein Friesian). Cattle were given 15 kg corn silage, 20 kg grass silage, and 3 kg grass hay as daily basal feed. A concentrate diet was given on the basis of the amount of milk production. Blood samples, Milk constituents, BCS and BFT were investigated every 2 months. Depending on the day postpartum of sampling, data were divided into 3 lactation stages; early (up to 75 days postpartum), mid (76 to 150 days), and late (after 151 days plus dry cows) lactation. Also, depending on the season at the time of sampling; the data were divided into 4 seasons, spring (April), summer (June and August), autumn (October) and winter (December and February). Statistical analyses were conducted with the SPSS; ANOVA was used for lactation stage and season comparison. The interaction between the two factors of the year was done by MANOVA. Results: Lactation stage had a significant influence on both blood metabolites (glucose, BHBA, blood urea nitrogen (BUN), albumen, cholesterol, Mg) and milk components ( milk fat, milk protein milk urea) in addition to BCS and BFT. No significant effect of the lactation stage was detected on total protein (TP), Ca, P, Cu and Zn. At the same time the season of the year has a significant impact on all parameters studied except BHBA, P and BFT. BCS was higher at late lactation (mean±SD) (3.36±0.41) than early (3.23±0.44) and mid (2.91±0.39) lactation. A significant interaction between stage of lactation and season of the year was detected for TP, cholesterol and milk protein. BFT correlated positively with BCS (r=0.84) and also milk urea and BUN (r=0.84) correlated positively. Milk yield and milk protein were correlated negatively(r=-0.61). Both BCS and BFT correlated negatively with cholesterol r= (-0.4). Conclusion: Stage of lactation and season influenced the biochemical parameters and metabolites in blood and milk as well as body condition. Therefore, the interaction between these two factors be taken into account when assessing the nutritional status of dairy cows in different climatic periods and in different stage of lactation. 542 Occurrence of Subclinical Metabolic Disorders and Possibility of the Prevention by Licking Block Supplementation in Beef Cows L. Könyves 1 , V. Jurkovich 1 , A. Tirián 1 , L. Tegzes 1 , O. Szenci 2 , Z. Szelényi 2 , E. Brydl 1 1 Szent István University Faculty of Veterinary Science, Department of Animal Hygene, Herd-health and Veterinary Ethology, Budapest, Hungary 2 Szent István University Faculty of Veterinary Science, Clinic for Large Animals, Budapest, Hungary The aim of the study was to reveal the occurrence of subclinical metabolic disorders in charolais suckler herd in the winter calving period and spring breeding season. The biological effect of an experimental licking block containing protein source, molasses, minerals and vitamins was also evaluated as a possible tool of preventing metabolic disorders. Charolais cows (n=114) were selected randomly into experimental and control group (n=57-57). From these groups 12-12 cows were assigned randomly for metabolic profile tests. The experimental group was supplemented with experimental licking block (voluntary intake about 1.5 kg/cow/day) from 1 month before expected calving until the end of breeding season. Different manifestations of energy imbalance (increased fat mobilisation, hypoglicaemia, hyperketonaemia) and acid load was diagnosed with high occurrence in both groups. Protein-, phosphorous-, sodium- and carotene shortage was diagnosed in the control group. The urea, phosphorous, carotene concentration in blood plasma and sodium concentration in urine were significantly higher in experimental group compared to control. The licking block had no effect on energy metabolism, acid-base balance, Ca, Mg, K, Cu, Zn, Se and Mn supply. There was no difference between groups in mortality- and culling rate, the postnatal calves mortality, metritis and the number of veterinary 42 XXV. Jubilee World Buiatrics Congress 2008 treatments.

O’Grady, R. Alibrahim, V. Gath, M. Doherty, F. Mulligan University College Dublin, School of Agriculture, Food Science and Veterinary Medicine, Dublin, Ireland The objective of this study was to determine the effect of body condition score (BCS) at calving and supplementation with a live yeast culture (Yea-Sacc 1026 , Saccharomyces cerevisiae, CBS 493.94) beginning two weeks pre-calving on the metabolic status of peri-parturient dairy cows. Forty Holstein/Friesian cows of mixed parity were randomly allocated to two groups depending on BCS approximately 60 days prior to parturition. Both groups were fed grass silage ad-libitum for the entire 60 days precalving and half of each group were supplemented with a dairy compound containing 2.5g of thermo-stable yeast supplement for the last 14 days pre-calving and during the first 70 days of lactation. Blood samples were taken via jugular venipuncture on the day of calving (12-24 hrs post calving) and on days 5, 15, 25 and 35 post-calving and analysed for Ca, Mg, P, gammaglutamate transferase (GGT), glutamate dehydrogenase (GLDH) and bilirubin (BIL). Data was analysed using ANOVA and the Proc GLM statement of SAS separately for each day of sampling as a 2 X 2 factorial with BCS group, supplement group, BCS group x supplement group and parity included in the model.

The concentrations of Ca, P, Mg and 25-OHD 3 were compared by repeated measures ANOVA. BCS and BFT were compared by student´s t-test. Significant difference was found in concentration of Ca, P, Mg and 25-OH D 3 with respect to time sampling (p
