Recent findings have shown that microbial nitrogen flow and digestible energy of diets are increased when urea is combined with a slow-release urea (SRU) in diets with a starch to acid detergent fibre...
Effects of Chromium on Energy Metabolism in Lambs Fed with Different Dietary Protein Levels
Lamb Chromium Protein Level Energy Metabolism
2016/5/4
The effects of chromium (Cr), dietary crude protein (CP) level, and potential interactions of these two factors were investigated in term of energy metabolism in lambs. Forty-eight 9-week-old weaned l...
