high non protein nitrogen animal feed supplement rations as set forth in table 5 when it was reasonably feasible for the particular formulation measurements were taken of the granule 39 s resistance to attrition rta angle of repose ar of a conical pile of the material and or hygroscopicity as set forth in the table for comparison on hygroscopicity prilled urea had a weight gain of 209 milligrams per square centimeter in 16 hours in this usage it is highly desirable to the animal feed formulator to provide a balanced ration of around 10n 1s and further desirable to provide additional calcium and phosphate based on the foregoing examples no formulations were made with calcium sulphate dihydrate as a calcium and sulfur source in the first comparisons formulations 1 and 2 an animal feed supplement based on dicalcium phosphate as the phosphate source was extremely difficult to process even with hemihydrate or anhydrite in small scale laboratory evaluations of a compaction granulation production of these materials it was found that the formulations caused considerable sticking during powder feedings difficult sticking during blending the compacted sheet tended to melt and the product on hygroscopicity tests gained considerable moisture and evidenced hard clumping reformulating with tricalcium phosphate formulations 3 5 overcame stickiness in processing and resulted in an easy flowing granule that had little tendency to pick up moisture the processing ease and lower hygroscopicity is quite evident in the two formulations with monoammonium phosphate formulations 5 and 6 where 5 also contains tricalcium phosphate but 6 for comparison did not contain any tricalcium phosphate formulation 7 illustrates that satisfactory urea monoammonium phosphate blends may be satisfactorily compaction granulated with the calcium sulphate compounds of the.
