“…Only 1.6% of the operations in our sample were classified as organic. Pasture grazing is associated with high SCC values (Pomiès et al, 2000), and certification requirements leave US organic dairy producers with relatively limited choices when treating cows for bacterial diseases (Ruegg, 2009). In the event of mastitis, organic producers are likely to face greater losses than under conventional practices due to higher unit production costs (McBride and Greene, 2009).…”

Consumer and processor demand for high-quality milk has placed increasing pressure on US milk producers to achieve higher product standards. International standards for somatic cell count (SCC) are becoming more stringent, but in May 2011, the United States National Conference on Interstate Milk Shipments chose to retain the 750,000 cells/mL standard. Using ordinary least squares and quantile regressions on US Department of Agriculture Agricultural Resource Management Survey Dairy Costs and Returns Report data for 2005, we model producer and farm-level characteristics associated with SCC. Quantile regression analysis allows for a more parsed inquiry into statistical associations. Dairy Costs and Returns Report data provide cross-sectional information on the physical structure, input expenses, demographics, and outputs for farms in selected states. Location outside the Southeast, lower herd age, full-time farming status, use of biosecurity guidelines, good milking facilities and operations management, and application of related quality tests are all associated with lower SCC levels. Size of operation had little effect on SCC levels after controlling for other factors. Many of the operations that did not attain a more demanding SCC standard of 400,000 cells/mL had older operators, operators who expressed intention to exit within 10 yr, smaller size, and location in the Southeast when compared with those meeting the tighter standard. The results suggest that the stricter scheme favors larger farms that are more committed to production and are less likely to be sole or family proprietorships.

The somatic cell count (SCC) in individual cow milk was used as an indicator of the udder health of cows in the mountain area in the Czech Republic. The monthly test-day records on SCC in milk of total 12,788 cows from 26 herds were scrutinized in order to elucidate the impact of the seasonal grazing on occurrence of milk secretion disorders. The interaction between the season (summer: May−October; winter: November−April) and the feeding system (seasonal grazing; permanently-indoor feeding) effects was used as a measure of the effect of pasture on SCC. The effect of season significantly interacted with the effect of farm (P < 0.001) and the between-farm variation in SCC was higher than the seasonal variation on particular farms. In both the feeding systems, the SCC was lower in the summer season than in the winter season (P < 0.01). The effect of season did not interact with the effect of feeding system (P > 0.05). The Holstein cows had on average higher SCC than the Czech Fleckvieh cows (P < 0.001) and this genetic effect did not interact with the season nor with the season and the farm effects (P > 0.05). The results indicated a higher importance of the management and the genetic factors for the occurrence of milk secretion disorders in comparison to the seasonal factors. No negative effect of the seasonal grazing on udder health was identified.

“…The highest SCC and microbial cell load were found in B and D milk. Although somatic cell count is related to physiological, sanitary, and climatic factors, it enhances during the pasture grazing period (Pomiés et al 2000) so the result for B and D milk was attributed to the rearing and feeding system adopted by the farms which provided pasture to cows during daytime and a concentrate supplementation in the cowshed.…”

Influence of milk quality and production protocol on proteolysis and lipolysis in Monti Dauni Meridionali Caciocavallo cheese

The aim of this study was to assess the effect of milk source and of cheese production protocol on proteolytic and lipolytic pattern of cheese during ripening. The study involved six dairy factories located in Monti Dauni Meridionali area of Southern Italy; three dairy factories processed the milk produced by their own cow herds, while the other three dairy factories processed the milk collected in other dairy farms located in the neighbouring area. Cow milk processed to cheese had different nutritional parameters and hygienic quality. Caciocavallo cheese showed differences in the evolution of proteolysis during ripening and in the intensity of the lipolytic process detected at the end of ripening. The main factors influencing Caciocavallo cheese features were the quality of the starting milk, differences in technological steps such as milk heating, type of starter cultures and coagulant used.

Effect of turning out dairy cows to pasture on milk somatic cell count

Abstract: -An increase in milk somatic cell count is often observed in commercial herds when cows are on pasture during summer. The objective of this study was to check, in experimental conditions, if this effect is due to the turning out to pasture.
