ABSTRACT:
Studies were conducted on 6 farms with the purpose to determine the balance of nutrients N, P and K, their conversion to livestock production and retention in manure as well as losses under different cattle housing and feeding and manure handling technologies. The data analysis of conversion of feed nutrients into production indicated that cows, when kept in cold deep litter and cubicle barns, absorbed from the feeds 17.1–22.9% of nitrogen, 17.9–31.6% of phosphorus and 6.1–16.2% of potassium for milk production. Conversion coefficients for nitrogen, phosphorus and potassium into milk production for cows in stanchion barns were, respectively, 24.7–25.4%, 22.4–32.0% and 15.5–18.9%. The nitrogen emission factor of 7.6–8.0% was determined in warm stanchion barns, while in cold loose deep litter barns it was 9.6–11.7% and in cold cubicle barns 3.9–15.1%. The highest nitrogen losses in manure storage were determined in storage of littered manure from warm stanchion barns (56.8 ± 7.0%). Nitrogen losses from a semisolid manure storage were 30.0–47.0%. The amount of semisolid manure as percent of total manure accumulated in deep litter barns with the non-littered feeding zone accounted for 32.8–50.0%.
