The microbial efficiency synthesis, the abomasum nitrogen compounds flow, the nitrogen compounds balance, the passage rate of ruminal digest, the ruminal ammonia concentration and ruminal pH in cattle fed diets containing Tifton 85 bermudagrass hay with different regrowth ages were evaluated. Four rumen and abomasum fistulated zebu cattle with average 340 kg LW were allotted in a 4×4 Latin square. All diets contained 60:40 forage to concentrate ratio. The forage was consisted in Tifton 85 bermudagrass hay with 28, 35, […]
