“…The losses from one case of mastitis are equivalent to the cost of 240 kg of milk in Denmark (Eriksson, 1991) and 400-470 kg in the USA (Kaneene and Hurd, 1990) . The occurrence and distribution of this disease depends on set of the factors, first of all on paratypic factors (Arney et al, 1996;Fourichon et al, 1996;Kaustell et al, 1996), immune system status (Schukken et al, 1994), age of animals (Sandholm, 1995;Poso and Mantysaari, 1996), and level of milk production in herds (Heuven et al, 1988;Banos and Shook, 1990;Boettcher et al, 1992;Collean and le Bihan-Duval, 1995).…”

The frequency of mastitis in more than 28 thousand cows was investigated. We report on how age and level of productivity, season of the year, "milkmaid" factor, udder properties, and hereditary factors influence mastitis frequency. The influence of the mothers and fathers on resistance or predisposition of the daughters to mastitis is shown. Among daughters from sick mothers the disease is two and more times higher than in the offspring of healthy cows; the frequency of mastitis ranges among families from 0 up to 57%. High variability of the sire's breeding value on mastitis stability (from-4.2 up to +24.0%) was found established. The factors of mastitis inheritance are low, on average 0.1. It is possible to estimate the bull's effect on resistance to mastitis in first-calving cows if a significantly large group is available. Among the bulls assessed in mastitis, sires were found to be plus proven (29.6%), neutral (44.4%) and poor proven (26.0%) in relation to the resistance parameter. The ranks of the bulls on mastitis frequency in the daughters and on sire's breeding value are characterized by high reproducibility (0.7 and more). The hypothesis about the polygenic type of inheritance of mastitis was confirmed on the basis of histogram analysis of the distribution of the half-sibs and female families on mastitis frequency. The annual realized genetic trend in mastitis varied from 2 up to 9% depending on the cow's age. It is possible and necessary to select dairy cattle to increase resistance to mastitis simultaneously with selection for milk productivity.

“…Although part of the phenotypic trend may be explained by the small increase in the proportion of Holstein-Friesian breed, the Finnish dairy cow feeding type tends to sustain high fat concentration (Huhtanen, 1998). In contrast, the genetic trend of dairy cows for milk protein concentration is close to zero (FABA, 2005) suggesting that the positive phenotypic trend is due to more intensive feeding or more evidently because farms with a low feeding intensity have finished milk production (Kaustell et al, 1996;Huhtanen and Nousiainen, 2004). Kaustell et al (1998) reported based on milk recording data that with increasing milk yield the increase in milk protein only partly compensates the lowering milk fat concentration.…”

The traditional milk quality concept reflects solely the dairy processors demands for raw milk quality. The quality criteria included typically concentration of fat and protein as well as milk hygiene (total plate and somatic cell counts) and possible some other physical traits, which still form the milk payment scheme on most countries. The consumer awareness of e.g., animal health and welfare and tightened customer demands for traceability of food items in the international trade has resulted in renewed milk quality concept. Total Quality Management systems are important tools for dairy industry to achieve customers' and consumers' trust for the good management practise of the whole milk chain and safe dairy products.
