USAGE OF PLASTIC LITTER MADE FROM SEPARATED SLURRY IN FARM ANIMAL BREEDINGS ESPECIALLY IN CATTLE

Abstract

The observation was performed in two dairy cows´ herds of Holstein breeding stabled in brick buildings with loose box stabling system. The separated slurry was used as litter in one of the building, classical stabling regime with straw litter was used in the other one. The experiment ascertained a significant tendency to reduction of microorganisms and parasites quantity in separated slurry modified by biometric treatment through the method of managed composting process. There was quite a small quantity of microorganisms and parasites in samples taken from litter of separated slurry and only after three weeks a gradual proliferation of them began. From the viewpoint of the dairy cows´ state of health, the quantity and quality of their milk production, the cleanness of their body surface, the periods of their lying and other ascertained welfare parameters under given microclimatic conditions the application of separated slurry as plastic litter fully complied.
