The aim of the study was to determine the effect of the thickness of litter on its physical parameters /temperature, heat loss, water and oxygen contents/ and thermic properties of the floors in standard laying houses at summer high temperatures. It was found that in shallow litter /up to 10 cm/ the inside temperaturo and external radiation temperature of the upper layer were significantly lower,...
During cold seasons/outdoor temperature ranging from -6 to 15°C/ it ia possible to keep the optimal microclimatic conditions in cold 3-storey battery laying house except for CO₂ concentration /max. value 0.54%/ air microflora /max. value 769.3 thousand/m³/ and light intensity minimal value 1.8 lx/. Statistically significant differences occured between the upper and lower storey of battery cages in...
Отметили, что применение мобильных усторйств для облучения ультрафиолетовыми лучами (типа UNZ2 с лампами РRК-2) при дозе 150 меров/м2/ч вызыавет понижение числа микроорганизмов в воздухе фермового телятника на 60,0% (от 169,3 тыс/м3 до 67,8 тыс./м3), а также в шерсти телят даже на 82,8% (от 6730 тыс./г до 1164,5 тыс./г). Больше всего изолировали бактерий из рода Streptococcus sр. (81,5—89,6%), а (81,5—89,6%),...
The purpose of the studies was to stablish if the conditions of an industrialized farm influence the maternal behaviour of sows — Polish Landrace (PL), Large-White-Polish (LWP) breed and crossbreeds. For this purpose the behaviour of sows in relation to their progenitire in three succesive farrowings was analysed. It was found and analogy in the behaviour between sows of PL and LWP breed. For these...
