What are the main causes of poor quality silage?

There are two kinds of inferior silage: one is rancidity silage. This kind of silage has insufficient sourness, has obvious rancid odor, is pungent, mostly dark green, has high water content, and feels sticky and smooth when touched by hand. This rancidity silage poor palatability, nutritional value is very low, if the beef cattle eat too much can cause diarrhea. The main reason for this poor quality feed is that the silage material is not harvested within a suitable period of time, the water content is too high, and the drying is not carried out, or the rainwater enters during the silage process and after the silage. Another poor quality silage is coked silage with a burnt or musty brown or dark brown color. Its low moisture content, poor palatability, low nutritional value. The reason is that the silage material is too mature and the harvest is too late. The raw material is cut too long, it is not easy to compact or the kiln is not timely, the delay is too long, and the cap is too late, resulting in too much heat for the silage material due to oxidation.

What should pay attention to silage feeding? Silage is popular among farmers because of its rich resources, low prices, and high feed value. There are fewer green and blue fodder in autumn and winter and it is a good time to feed silage. However, some farmers often pay no attention to methods when they open the cellar, causing unnecessary waste. When stratified materials are taken for silage, they must start from one end of the pit and, according to a certain thickness, be taken from the surface layer by layer, so that the green feed always maintains a flat surface and should not be picked up by a burrow. Pay attention to the amount of material to be fed for one day at a time. How much material should be taken from the animal per day should be taken, and feeding should not be carried out for a long time so as to avoid deterioration of the feed. Timely sealed cellar mouth after silage removal, the cellar mouth should be sealed in time to prevent long-term exposure of green feed in the air deterioration, feeding caused by poisoning or other diseases. The amount of silage from so many to many silage beverages has a sour taste. At the beginning of feeding, some of the livestock are not accustomed to feeding. In order for the livestock to have an adaptive process, the feeding amount should be increased from small to large, and gradually. Generally, the amount of feed per head (only) is: cows and fattening cattle of 20 to 25 kilograms; cattle of 10 to 15 kilograms, and adult sheep of 2 to 4 kilograms; horses, donkeys, and elk of 7 to 12 kilograms. Note that a reasonable mix of silage is a high-quality roughage, but it must be properly matched with the nutritional requirements of the livestock and concentrates and other feeds. Silage and other feeds are fed together to increase feed utilization. If the acidity of the silage feed is too high, the amount of silage should be reduced or the amount of silage used should be reduced. It can be used in 5 to 10% of the lime water and then fed, or added to the mixed concentrate by 12%. Baking soda (Na2CO3) to reduce the acidity of the stomach. Do not use deteriorating feeds. If the appearance of silage is dark brown or black-green, smelling of sour smells, blowing nose, or rancid odor, and sticky feel, it means that the feed has been deteriorating, and it should be picked out immediately and never used. Feed livestock.
