Research of possibility of application of sapropel (putrid mud) of the Chervonnoe lake (the Republic of Belarus) in diets of bred and milking sows as one of the ingredients of mixed fodders, as well as the evaluation of its influence of sow development and digestibility of nutritive elements were studied. Application of dry sapropel a source of energy, protein, mineral and vitamin nutritive elements for mixed fodder production rendered the positive influence on sows productive qualities: there was stated the increased number of born piglets on o,5 heads with a higher growing capacity; there was noted the increasing of coefficients of nutritive elements metabolism (crude protein – on 2,7%, crude fat – on 2,9%, free-nitrogen extracts – on 1,3%, and dietary fibre – jn 4,7%) with the simultaneous increasing of nitrogen, calcium, and phosphorous uptake by sows. Nutritional value of the analysed sapropel was 0,23 fodder units and 3,13 MJ of exchange energy per 1 kg of dry matter. Inclusion of 3% sapropel into mixed fodders for pregnant and suckling sows promoted the increasing of quantity of pigs at a birth, body weight of one pig to 3-week age and has ensured young growth with higher energy of growth. Use of sapropel in mixed fodders for sows makes active a metabolism and promotes increase of digestibility of the basic nutrients of a rations
