| Abstract: | dairy cattle at top milk production were selected and random allotted into experimental group and control group. They were both fed with the same diet and supplement feed but the experimental group was added with 0.8% sodium bicarbonate. The result shows that milkfat percentage and milk yield of the cows in experimental group increased 1.98% and 11.21%(p<0.05) respectively and the cost of supplement feed per kilogram milk yield reduced 5.88%. |
