The aim of research was to evaluate changes of physico-chemical characteristics, somatic cell count and curd quality during lactation and their relationship in Lacaune ewes. The study was carried out on eighteen ewes of the second lactation on an organic farm in Valašská Bystřice (Czech Republic).

Selection for breeding animals as parents of next generation, based on genetic analyses of most important traits, became a standard for selection practices in most of the farm animal species in Slovakia. In this respect, about ten years of experience could be traced in Slovakian dairy cattle (Candrák et al., 1997) and pigs (Groeneveld and Peškovičová, 1999 and Peškovičová et. al., 1999). First ...

To study the pathogenesis of bovine spongiform encephalopathy infection in small ruminants, two Lacaune sheep with the AA136RR154QQ171 and one with the AA136RR154RR171 genotype for the prion protein, were inoculated with a brain homogenate from a French cattle BSE case by peripheral routes. Sheep with the ARQ/ARQ genotype are considered as susceptible to prion diseases contrary to those with th...
