The study was conducted to investigate the effect of applying of two different additives to the straw litter on the physical and chemical characteristics of bedding and on turkey broiler performance.In building B-1 birds were kept on straw supplemented with brown fine coal, in building B-2 litter was sprayed with EM-1 microbe vaccine solution (200 ml/10 l water) twice a day. Building B-3 was a control object. During the experiment thermo-vision photographs of the surface and the inside layers of litter were taken. Once a week determined were the extent of litter surface encrustation and the health status of legs in turkeys. After rearing, final mortality and body live weight were specified.Both tested additives led to the significant rise in litter temperature, which positively affected its physical parametres and contributed to the improvement of the birds’ welfare and performance (lower mortality, higher final weight).
