ABSTRACT

The aim of the study was to determine an influence of multicomponent preservative added to complete mixtures with lowered protein level for pregnant and lactating sows on nitrogen emission with faeces and physiological indices. The research material were 42 sows divided into 3 nutritional groups. The level of protein and amino acids in the control group was in accordance with recommendations included in Polish standards. The level of protein in experimental groups was lowered of 10 and 20%, and level of lysine, methionine, threonine and tryptophan was complemented to the level of the control group. The preservative in friable form was added to all mixtures for pregnant and lactating sows in amount of 0.8%. All sows during pregnancy and lactation were fed individually. Samples of faeces and urine from 8 sows from each group were collected at 60th and 105th day of pregnancy. The content of dry matter, nitrogen, fibre and ash was determined in faeces samples and nitrogen content was determined in urine. Blood from the jugular vein was collected from 24 sows (8 from each group) on 14th day of lactation, and protein and fat transformation indices and minerals content were determined in serum. The obtained results of faeces and urine analysis prove that sows from the experimental groups released lower amount of nitrogen by 4 and 7% in faeces at day 60th, and of 10 and 12% in urine. During high pregnancy period (105th day) they released less nitrogen of 4 and 8% in faeces, and of 13 and 30% in urine. A decrease in total protein level and urea, and an increase in cholesterol level was observed in blood serum of both experimental groups sows. Protein level in mixtures fed did not influence neither the content of minerals in blood serum nor haematological indices of blood.

Key words: sows, protein, nitrogen, amino acids, faeces, urine.
