Summary

Water metabolism of two breeds of sheep (Uda and Yankasa)and two breeds of goat (Sahel and Maradi) was studied. Tritiated water space as a percentage of live weight was 80·5 and 73·6 % for Uda and Yankasa, respectively, and 77·8 and 66·1 % for Sahel and Maradi, respectively. The biological half-life of tritium was least in Yankasa (115 h) and longest in Sahel (173 h). Water turnover (I/day per animal) was 2·52, 2·63, 0·86 and 1·09 for Uda, Yankasa, Sahel and Maradi, respectively.
