In a 4 X 4 Latin square design 4 Murrah buffaloes were given groundnut cake, cottonseed cake, guar meal or urea and groundnut cake. All were offered 6 kg wheat straw daily. Crude protein of the concentrate mixtures with straw was 16%. Blood was sampled before and 2, 4, 6 and 8 h after feeding. Urea N in blood plasma in the group given urea was significantly more than on other diets. With all diets urea in blood plasma was highest 4 h after feeding; urea gave significantly higher concentrations in blood at 2, 6 and 8 h. Cottonseed cake generally gave lower concentrations of blood urea N, significantly lower at 4 h after feeding. The pH of blood was highest (7.3 to 7.4) 4 h after feeding, but at no time were there significant differences between diets or between time intervals.
