| Summary: | ABSTRACT This article describes two cases where adult dairy or beef cows, fed exclusively with corn or sorghum silage, began to ingest urine greedily. Providing 20 to 40g of urea/100kg of body weight was able to suppress urophagia in these two herds. In a situation where adult cows, not supplemented with protein concentrates, are ingesting urine, professionals should suspect a nitrogen deficiency in the diet. The diagnosis can be confirmed if urophagia stops after 15 to 21 days of supplying 20 to 40g of urea/100kg of body weight. Differential diagnoses of Na and Co deficiencies should be considered in episodes of urophagia. |
