The present invention relates to a concentrated feed for simultaneous reduction of
nitrogen,
phosphorus and
methane emission of cow. The concentrated feed includes: 46%-50% of corn, 5%-8% of a concentrated molasses
fermentation liquid, 18%-24% of wheat
bran, 6%-10% of
cottonseed meal, 6%-10% of
soybean meal, 0.7%-1.2% of salt, 1%-2% of
sodium bicarbonate, 0.5%-1% of
magnesium oxide, 1.0%-2.0% of stone flour, 0.15%-0.25% of
isobutyric acid, and 0.08%-0.12% of 1%
oregano oil powder. The invention uses the concentrated feed to regulate
rumen fermentation of cow, improve intestinal
amino acid balance and reduce dietary
phosphorus levels in order to improve the utilization of
nitrogen,
phosphorus and energy, and the rate of
milk production, as well as to reduce emissions of
nitrogen, phosphorus and
methane in dairy. The invention has
economic benefits of reduce feeding cost and improving the utilization of nitrogen, energy and phosphorus of the cow, and
milk yield, and has ecological benefits of reducing the emissions of nitrogen, phosphorus and
methane in dairy to reduce environmental
pollution, and integrates production increase, energy saving and emission reduction in one.
