ABSTRACT:
Studies were conducted at the Lithuanian Institute of animal Science to determine the balance of nutrients N, P and K, their conversion to livestock production and retention in manure as well as nitrogen losses under different cattle housing and feeding, manure handling technologies. The data analysis of transition of feed nutrients into excrement indicated that cows, when kept in confinement in loose and stanchion barns, retention from feed was 72.4-81.2% of nitrogen, 74.7-71.6% of phosphorus and 92.0-86.2% of potassium for excrement. Retention of nitrogen, phosphorus and potassium into excrement of calves till 8 months of age was respectively 83.9%, 68.6% and 96.7%. The average retention of nutrients into excrement of heifers from 9 to 27 months of age was 92.4% of nitrogen, 83.3% of phosphorus and 98.9% of potassium. A low nitrogen emission factor due evaporation of ammonia evaporation (1.60.2%) was determined in the stanchion barns, while in the cold loose cow barns it was 4.41.2%, in the calf houses 11.81.8% and in the heifer houses 17.03.9%. The data analysis of retention of feed nutrients into excretion indicated that fattening pigs, when kept on solid floor in barns, absorbed from the feeds 77.1% of nitrogen, 70.8% of phosphorus and 95.9% of potassium for excrement. Retention for nitrogen, phosphorus and potassium into excrement of weaners till 4 months of age was respectively 77.0-66.4%, 62.5-57.2% and 89.7-84.6%. The average retention of nutrients into excrement of gestatig sows was 85,4%, of nitrogen, 86,0% of phosphorus and 96,3% of potassium. Retention for nitrogen, phosphorus and potassium into excrement of lactating sows with piglets was respectively 65.1%, 62.7% and 86.8%. A low nitrogen emission factor due evaporation of ammonia (7.62.3%) was determined in weaners barns with housing on slatted floor. In the warm loose weaners barns on the semideep litter it was 14.52.4%, in the lactating sows houses, with limited amount of littering - 9.33.5% and in the gestating sows houses on the semideep litter - 14.03.5%. High nitrogen emission due evaporation of ammonia was determined in warm fattening pigs barns, where animals hold on slatted floor. Nitrogen emission was 21.96.90%.
