Effect of crude protein level of dairy cow feed on milk fat percentage
What is the effect of crude protein levels in dairy feed on milk fat percentage?
A: When the crude protein of dairy cow's feed is increased from 10% to 18%, it can increase the feed intake of dairy cows and enhance their
Digestibility; when the energy is negatively balanced, the milk production increases; the milk fat is diluted due to the increase in milk production, concentration
Reduced, no change in milk protein and lactose content. The crude protein in the feed increased from 15.4% to 20.7%.
It can increase the milk fat content from 3.56% to 4.16% in the early stage of lactation. And make the milk and the protein in the milk
There is an increase.
Reduced protein content in dairy mixed feed from 15.5% to 13.1%, and decreased milk fat percentage after 40 days
At 0.96 percentage points, the density dropped by 0.4 percentage points. Different protein materials have different effects on milk fat percentage.
Cottonseed can increase the milk fat rate, supplement the crude protein with cottonseed, and increase the dietary protein from 13.8%.
17.5%, the daily milk and milk fat percentage increased. Feeding all with cottonseed, which is beneficial to the synthesis of long-chain fatty acids.
Less milk protein content. The test also found that the un-hulled cottonseed had a high milk yield, while the unpacked cottonseed had a high milk fat percentage.
In addition, the addition of crushed soybeans can also increase the milk fat percentage.
