Autor: R. C. Ewan, Yongjiu Cai, Dean R. Zimmerman
Publikováno v: Canadian Journal of Animal Science. 76:351-355
Ninty-six 51 kg-pigs were used to determine effects of dietary protein and potassium levels on concentrations of plasma urea nitrogen (PUN) and free amino acids. Pigs were fed four diets containing 13 or 15% of protein and 0 or 0.4% of potassium addi
