Four diets with varying levels of urea (0 to 2.2%) and potassium (0.83 to 1.20%) were fed in succession to a group of eight animals. Microbial concentration and rate of growth were depressed by the decrease of potassium intake in urea containing diets. The influence of low potassium intake was more obvious on the bacterial population. Two adult Rahmany sheep were fed on a semi-purified diet containing urea as the only source of nitrogen. The animals remained normal until the 8 week after which they showed symptoms of vitamin 8 deficiency. Potassium balance which was slightly positive (0.2 g/d) at the normal state was negative (-3.6 g/d) at the stage of the disorder. |
