Four goats were in three singlereversal experiments to study effects of feeding ammonium chloride on various nutritional and physiological parameters.In Experimer~t I, feeding .56g of ammoninrn ctfloride per day per kilogram body weight to lactating goats fed a ration having a calcium-to-phosphorus ratio of 3:1 resulted in a reduced calcium retention and no change in phosphorus retention.In Experiments II and I/I, ingestion of .33 g of ammonium chloride per day per kilogram body weight by nonlactating goats, fed a diet with calcium-to-phosphorus ratios of 3.4:1 and 6.4:1 resulted in no change in calcium or phosphorus l~etention.Resuits which consistently accompanied treatment with ammonium chloride during each experiment were: (1) a decrease in dry matter intake, (2) a decrease in urine pH, (3) an increase, in total grams of urine excreted per day, and (4) an increase in total urinary excretion of nitrogen, calcium, magnesium, chloride, strontium, and zinc.
