| Abstract: | The impact of different energy supplement substances on the production of lactating dairy cows was discussed in this study. Controlled with wheat bran, whole cottonseed, extruded full fat soybeans and fatty acid calcium as an energy supplement substance were feeded to dairy cows in 35 days. Results showed that milk production was increased by 6.7%, 14.4% and 18.2% respectively. Milk fat was increased by 19.09%, 11.82% and 1 1.21%. Compared with the control group, the economic efficiency was improved by 4.20, 5.36 and 8.72 yuan / head-day, respectively. The tests showed that the whole cottonseed, extruded full fat and soybean fatty acid calcium could relief the negative balance of energy of cows, improve milk production and milk quality, especially fatty acid calcium had the best results. |
