Abstract The objective of this study was to present a relationship between mastitis in the post-calving period and fertility traits of dairy cows. The threshold of 200,000 cells/ml for somatic cell count is used as a reference for healthy quarters of the cow’s udder. The genetic correlation between mastitis and somatic cell count is strong (from 0.7 to 0.8). Although heritability for fertility traits is low (from 0.01 to 0.02), the genetic standard deviation for mastitis varies from 1.2 to 7.0 percentage units, suggesting that genetic gain can be achieved by selecting for mastitis. Results of this study suggest that mastitis in the postpartum period can have a markedly negative impact on the reproductive performance of dairy cows. The synergistic effect of common conditions (somatic cell count, body condition score and lameness score) or other factors (e.g. heat stress, fertility management, the presence of repeat breeders) also lowers fertility of cows. Production of milk with fewer than 100,000 cells/ml leads to improved health and fertility in the cows.

The objective of the present study was to investigate the effects of somatic cell count (SCC) and body condition score (BCS) on reproduction and milk composition characteristics in Czech Holstein cows. A total of 275 records of chosen cows was evaluated by milk composition, SCC, BCS and fertility traits. Infrared spectroscopic method was used for SCC test and an automatic device was used for milk composition analysis. Before statistical test, SCC data were transformed to log10 for normality and homogeneity of variances. BCS was performed using a 1-5 point scale and days from calving to first insemination (ICF), number of inseminations per conceptions (NIC) and days open (DO) were assessed as fertility parameters. To evaluate days in milk (DIM) on SCC and BCS, two groups were designed (group 1: cows in 1-69th day DIM and group 2: cows in 70-119th DIM). For testing BCS on chosen traits; cows with 2.50 £ BCS and cows with BCS ³ 2.75 were tested in two groups. All statistical work was applied by SPSS 17.0 at the 0.05 significance level. It was found that SCC elevated with high parities and cows with lower BCS had lower milk protein percentage. Cows with lower BCS had lower reproduction traits than those with higher BCS. Correlation coefficient between two markers was estimated as r= -0.181. Calculated means for the parameters could be assessed in reasonable thresholds. The study revealed that SCC played a marked role on protein percentage of milk, and BCS affected important reproductive characteristics of Czech Holstein cows.

The objective of this study was to determine some environmental factors affecting body condition score (BCS) and somatic cell count (SCC) in Czech Holstein cows. A total of 278 primiparous cows were examined by BCS and SCC in four calving seasons, three years and six test days after calving. The results revealed no significant effect of calving season was found for both parameters. While year was not effective on SCC values, BCS mean of third year was significantly (P

The Impact

Various studies in dairy cows have shown that their Body Condition Score (BCS) effectively reflects their nutritional status and energy content (Ferguson et al. 1994). Extremes in BCS and BCS losses have been identified as a risk factor for health problems and reduced reproductive efficiency (Markusfeld et al. 1997, Lopez-Gatius et al. 2003). Body condition scoring is easy and inexpensive to perform and gives a reliable estimate of body energy reserves. Hence, in practice, BCS can be used as a tool for ration formulation and management decisions concerning reproduction of dairy cows (Banos et al. 2004). The objective of this study was to determine and quantify the impact of BCS in the reproductive performance of primiparous Holstein cows.
