Mastitis is a complex disease causing inflammation of the udder, which has been estimated to cost the dairy farmer between £40-£117/cow per year (Stott et al., 2002). Economic loss occurs as a result of discarded milk, reduced milk yield and milk quality, increased vet costs and an increase in replacement costs. The objective of this study was to examine the effect of breed on the incidence of mastitis and somatic cell counts and milk production capabilities of Holstein Friesian, Brown Swiss and Brown Swiss crossbred cows.

Abstract. Title of the paper: Effect of soft flooring in free stalls on milk yield, fat, protein and somatic cell counts in dairy cattle Research conducted at the Experimental Farm Oberschleißheim focused on comparing milk yield, fat, protein and somatic cell counts in dairy cattle housed in free stalls with concrete slatted floor and rubber mats covering the concrete slatted floor. Data were collected from 49 cows in 53 lactation periods, which were divided into experimental group (n = 26) on rubber matted floor (EBG) and control group (n = 27) on concrete slatted floor (BBG). Housing conditions of both groups differed in kind of cubicles. EBG had soft rubber mat mattresses, BBG had cubicles with straw manure mattresses. Data analysed originated from the official milk performance testing of the "Landeskuratorium der Erzeugerringe für tierische Veredelung in Bayern e.V." and from activity counters worn by the cows. Statistical analysis resulted in a significant higher activity level of the EBG versus BBG. Milk yield and protein showed no significant difference between both groups, fat was significant higher in BBG. Somatic cell counts were significant lower in EBG. Data analysed regarding activity level classes showed a trend of decreasing milk yield and milk constituents with increasing activity. No evidence was found that soft floor results in higher milk yield. But a higher activity level of EBG cows might indicate a higher cow comfort on elastic floor.

Milk Cows

A high milk production, time limited milking and healthy udders are priority tasks at milking farms. The aim of our research was to study how different ways of keeping (free rang and tying) and milking (milking parlour, bucket machine and pipeline milking) influence on the mentioned cattle characteristics. Investigation was conducted at four milking farms and 382 Holstein cows in eastern Croatia. The variance analysis has shown significant difference (P<0,05) among researched farms for the milk yield per milking (MYM), the somatic cell count (LSCC) and the maximum milk flowing rate (MFR). Farms at which cows were kept and milked bound up in stables had more problems with udder health than farms at which milking was conducted at milking places. Also at these farms (at which cows were kept and milked bound up in stables) the maximum milk flowing rate was uneven, what was caused by uneven vacuum and obsoletes milking equipment. Keeping cows free at the stable and milking at a milking place have appeared to be more appropriate for cow?s udder health, what finally influences a higher milking production. Such farms should be the future of modern milking production in Croatia.

In spite of the impressive advancements observed on both management and genetic factors, udder health still represents one of most demanding objectives to be attained in the dairy cattle industry. Udder morphology and especially teat condition might represent the first physical barrier to pathogens’ access. The objectives of this study were to investigate the genetic component of teat condition and to elucidate its relationship with both milk yield and somatic cell scores in dairy cattle. Moreover, the effect of selection for both milk yield and somatic cell scores on teat condition was also investigated. A multivariate analysis was conducted on 10,776 teat score records and 30,160 production records from 2469 Italian Holstein cows. Three teat scoring traits were defined and included in the analysis. Heritability estimates for the teat score traits were moderate to low, ranging from 0.084 to 0.238. When teat score was based on a four-classes ordinal scoring, its genetic correlation with milk yields and somatic cell score were 0.862 and 0.439, respectively. The scale used to classify teat-end score has an impact on the magnitude of the estimates. Genetic correlations suggest that selection for milk yield could deteriorate teat health, unless more emphasis is given to somatic cell scores. Considering that both at national and international level, the current selection objectives are giving more emphasis to health traits, a further genetic deterioration in teat condition is not expected.

This study presented a potentially useful alternative approach to ascertain the presence of subclinical and clinical mastitis in dairy cows using support vector machine (SVM) techniques. The proposed method detected mastitis in a cross-sectional representative sample of Holstein dairy cattle milked using an automatic milking system. The study used such suspected indicators of mastitis as lactation rank, milk yield, electrical conductivity, average milking duration, and control season as input data. The output variable was somatic cell counts obtained from milk samples collected monthly throughout the 15 months of the control period. Cattle were judged to be healthy or infected based on those somatic cell counts. This study undertook a detailed scrutiny of the SVM methodology, constructing and examining a model which showed 89% sensitivity, 92% specificity, and 50% error in mastitis detection.
