anaerobes. Aerobic bacteria isolated from clinical metritis/endometritis cases were highly susceptible to amoxicillin/clavulanic acid. In treatment of infertility in cows, hormones and antibiotic products are mostly applied. The usefulness for treatment and prophylaxis of antibacterial compounds, hormones, antioxidants or immunomodulators and combinations of this medicine was tested by different scientific teams. Apart from the influence of the genital tract diseases, metabolic disorders and mastitis on the reproduction efficiency in cows, examinations were also conducted that concerned the regulation of the corpus luteum function, effects of xenobiotics on the genital tract, molecular basis and maternal recognition of the pregnancy and early embryo mortality. Key words: cow, infertility, diseases, treatment, prophylaxis 116 Factors of Non-infectious Nature Affecting Early Foetal Loss in High Producing Dairy Herds in North-Eastern Spain F.

We present here data derived from 14 studies and one abstract published in peer-reviewed journals during the period 1996 to 2008 that analysed the effects of factors of a non-infectious nature affecting early foetal loss in high producing dairy herds. Results included a total of 15,525 pregnancies in well-managed, commercial, Holstein-Friesian high producing dairy herds over the period 1987 to 2007. Since the effects of different factors practically did not vary throughout the years, data from the different studies were pooled and the relative risk of every individual factor on foetal loss is described. Points to be highlighted should include that strong risk factors for pregnancy loss were parity (lactating cows versus heifers), semen-providing bull, warm season and twin pregnancies, whereas the presence of an additional corpus luteum was identified as a strong positive factor favouring the maintenance of gestation. Progesterone supplementation had the potential to reduce the incidence of pregnancy loss. From a practical point of view, assessment of normal development of gestation on days 60 and 90 after insemination is suggested. Key words: early foetal loss, milk production, dairy cows 117 Performance Parameters and the Predicted Economic Return of Jersey Holstein-Friesian Crossbred Cows in Australian Pasture-based Herds M. Pyman, K. Macmillan, G. Anderson University of Melbourne, Department of Veterinary Sciences, Werribee, Australia This study compared the reproductive performance and milk production of Holstein-Friesian cows to that of Jersey Holstein- Friesian crossbred cows in 14 Australian herds. An economic model using the study results was developed to determine the profitability of crossbreeding in pasture-based, seasonally calving herds. Data were collected over a single lactation from 3,347 cows comprising 2,373 Holstein-Friesian (FFFF), 669 Jersey Holstein-Friesian first cross (JJFF) and 305 backcross (FFJF) cows. First service conception rates to artificial insemination were based on 2,179 FFFF and 894 crossbred cows. Reproductive performance of the crossbred cows was superior to the FFFF cows for first service conception rate (54.7% vs. 47.0%, p=0.0002), pregnancy rate after 14 weeks of breeding (83.7% vs. 77.0%, p
measures of fertility in German dairy herds. Raw milk production and composition, reproductive events and lactation number (LN) data from nearly 40,000 individual cow lactations were collected from the Verden and Bavaria Calculation Centers of German Breeding Test Organizations. A total of 28,620 completed lactations with all required data were used for analysis. Individual cow reproductive performance was characterized by time to first service (TFS), days open (DO), calving interval (CI), services per conception (SPC) and conception risk (CR). Parameters for lactational performance included milk per day (MPD), lactation yield (MY), milk fat (MF), milk protein (MP) and calculated milk fat-to-protein ratio (FPR). Milk parameters were summarized by days in milk groups of ≤40 (MPD40, MF40, FPR40), 41-to-80 (MPD80, MF80, FPR80) and >105 (MPD105, MF105, FPR105). Production parameters were stratified by quartiles for analysis. Interrelationships between production and reproductive parameters were analyzed using ANOVA and logistic regression models. Higher milk yield, irrespective of lactation stage, resulted in longer (P
