Preservation of moist hay with preservatives In order to be able to stock hay without spoilage, it must be dry enough. The use of preservatives / additives at baling of moist hay is an alternative. In two trials, the efficacy of two products, Schaumasil supra NK and KRONI 909.01 Stabisil, was investigated with hay with different dry matter contents. As negative control, variants without additives were tested. During a period of 30 days, hay temperature was continuously controlled. Before and after this period, the dry matter contents and different parameters were analysed. In contrast to the control variants without additives, the two additives Schaumasil supra NK and KRONI 909.01 Stabisil prevented the heating up and the spoilage of the hay with the different dry matter contents. Due to these investigations, the two products Schaumasil supra NK and KRONI 909.01 Stabisil were authorized for the stabilization of moist hay.

Even in temperate climate zones, an increase in the ambient temperature and solar radiation can cause heat stress in grazing dairy cows. Agroscope studied the physiological changes in cows caused by increasing heat load.

In dairy cows, herbage-based diets often lead to increased nitrogen excretion. Tanniferous sainfoin and extract of acacia can reduce nitrogen excretion from urine and thus ammonia volatilization from slurry.
Excessive nitrogen inputs from the air lead to over-fertilisation of sensitive ecosystems. Continuous feeding optimisation can make an important contribution to reducing ammonia losses and thus nitrogen inputs.
