Utilization of phosphorus and certain other minerals from swine waste and broiler litter
- Virginia Polytechnic Institute, Blacksburg (USA)
Two trials were conducted with 15 wethers surgically equipped with duodenal and ileal cannulas to study the utilization of P, Ca, Mg, Cu, Fe and Zn from swine waste and broiler litter. For each trial, animals were fed a low-P basal diet until serum inorganic P averaged 5.5 mg/dl; then they were allotted at random to the following 50% DM ensiled diets: low-P basal, basal + swine waste, basal + broiler litter, basal + dicalcium phosphate and basal + soybean meal. Each trial consisted of a 7-d preliminary period, a 7-d collection of feces and urine and 6-d sampling of duodenal and ileal digesta and feces. Apparent P absorption was not different (P greater than .05) between sheep fed waste-supplemented diets (37%) and those fed the conventionally supplemented diets (28%). Phosphorus absorption, calculated by difference, tended (P less than .1) to be higher from the waste supplements (59%) than from dicalcium phosphate and soybean meal (37%). Less (P less than .05) Ca was absorbed from the waste diets (.62 g/d) than from the conventional diets (1.28 g/d). More (P less than .05) Cu (mg/d) was absorbed from the waste diets, but no difference was found when absorption was expressed as percentage of intake. Broiler litter and swine waste were good sources of available P and Mg for ruminants.
