Influence of extreme high and low temperature on the quality of maize silage and milk yield of dairy cows

Original language description

From the dietetic point of view, it is not recommended to feed dairy cows (especially the high-producing ones) either with frozen food in winter or with aerobic deteriorated maize silage in summer. Schnier et al. (2003) relate freezing weather with the influence on milk production. Their ret­rospective study followed the curve of milk yield of cows bred in so called "cold" system of free stabling as compared to classical system. The cows in "cold" system produced one litre less milk daily but the difference was not statistically significant. The influence of changes of daily temperatures on milk pro­duction is usually related to breed of beef cattle in summer, in arid areas, or in breeding in insufficiently ventilated stables. That results from the survey processed by Kadzere et al. (2002). When strong heat and humidity last long time, high milk yield, good health and welfare of dairy cows must be preserved by combination of all available possibilities, i.e. cooling down (particularly
