Diet system of milking cows with silage of wet corn

Abstract

In the five trials rationed with the basic component being the silage with a high moisture percent, around 70%, particular attention was paid to the nutritional value, i.e. consuming of hay to be minimally 2 kg hay/100 kg body mass of cows.

The first ration combination, with conventional silage of the wet ear and two concentrate mixtures with 32 and 20% proteins, proved to be successful allowing the diet with this type of the meal was excelling over the first lactation stage, while at its end, the cows were somewhat more fattened than expected.

The second combination of meals, i.e., a separate provision of different combinations required solely individual diet or division of the cows into smaller groups according to the production level.

The third combination of the meals, i.e. whole meal with the silage mixed with concentrate, required that ready meal be mixed right before feeding, particularly over the warm and wet weather. Addition of ration 0.2-0.3% Ca-propionate for feed conservation can be recommended.

The fourth combination, i.e. whole meal made at feeding time also gave good results, so we strongly recommend its crushing and mixing during nourishment with “mixing” trailers.

The fifth combination of meals was made during ensilaging. In this meal, special attention was paid to the share of mineral matter in the meal of the macro and micro elements.

The diet with above presented combinations of the cow meals caused no digestive disturbances and gave good production and reproduction results over the whole period of experimentation.
