Silage feeds young and empty cows to meet their protein requirements. At present, the application of urea to feed cattle and sheep is to mix the urea and the concentrate to feed evenly, so that although it can achieve the effect of supplementing protein, it affects the feed intake of the concentrate. When urea is added to silage, the relative concentration is reduced due to the large amount of feed, which will not affect the feed intake of silage by cattle and sheep.
Method for adding urea to silage: Before the silage starts, firstly prepare the urea into a 25% solution (ie, add 25 kg of urea to 100 kg of water) and store it in a container. When silage, use a micro-spray while smashing the corn stover. Spray the urea solution on the surface of the corn stover. Spray 25% of urea solution 20 kg per ton of silage corn stover. Spray while spraying, and spray evenly.
