The article summarizes the influence of farm conditions on sows blood morphological parameters. Our research was carried out in the farms of Zolochiv and Starosambir districts of the Lviv region (Ukraine) and revealed strong violations of animals feeding, both in terms of nutrition, and on the macro- and microelement composition. In all the farms, there was practically no appropriate way to feeding sows from different physiological groups, which may further adversely affect the growth and development of the resulting offspring. The parameters of the microclimate in the premises were invested in the limits of permissible norms. The differences between farms were production process and pigs keeping. Animals of the Zolochiv region were not registered and had the opportunity to move freely, to nest before the farrowing, to satisfy their physiological needs for food search (to dig, to throw the bedding), without barriers to consume food and water. In the farm of the Starosambir district the sows were kept in individual fixing machines, they were restricted in movement, free choice of place for rest, manifestation of natural behavior, the ability to satisfy the instinct of nesting and show the instinct of caring for the offspring. Free holding of sows have a positive effect on the processes of hematopoiesis. The blood of these animals had more red blood cells and the hemoglobin concentration was higher. It was also proved that the most susceptible to the conditions of containment were farrowing sows from both farms, as evidenced by the morphological indices of blood. Thus, the number of erythrocytes, hemoglobin concentration, hematocrit magnitude and red blood indices in animals of this physiological group are recorded at the lower limit of the physiological norm.
