First, often open before the open cellar. After the silage material was sealed, it was found that the covered plastic film was damaged and timely refilled, and the rainwater was prevented from flowing into the pit and the grass was damaged.
Second, after opening the cellar quality. After 40 days of silage fermentation, the silage can be opened for use. The quality of the silage should be determined from the color, smell and texture. A look at the color: If the straw before silage is green, then the color after silage is greenish green or yellowish green, close to the original
Colors are excellent; yellow-brown or dark brown are moderate; black or brown, dark green are the worst. Smell smell: High-quality silage has a slight acid or fruit aroma. It tastes sour and pungent, like freshly cut fresh bread; if it is sour and pungent, it is very light.
Moderate; if there is a nauseating, pungent rancid or musty odor, then the feed has deteriorated. Three check textures: good silage pressed in the cellar is very solid, and grasping the hands is very loose, no sticky feeling, soft and slightly moist texture, stems and leaves still remain the same.
Third, access methods are flawed. When opening the pit, remove the mud from the pit side of the pit. The rectangular cellar should be open from one end of the upwind and take the material in a cross-section, taking at least 6 cm to 7 cm thick each day. After taking the cross-section to keep horizontal and vertical, can not be in the form of holes
Dig deeper so as not to cause secondary fermentation. The circular cellar should be taken from the surface layer by layer, so that the silage always stays on a flat surface and should not be picked up from one place. Regardless of the form of cellar, the exposed layer must be tightly sealed with a plastic sheet after each withdrawal.
It is airtight. When the weather is hot, you have to take it with you to ensure the feed is fresh.
Fourth, pay attention to feeding livestock. Silage is high quality, juicy, nutritious, and palatable. However, if the feeding is not scientific, it is difficult to receive good results.
1, patience to feed, gradually transition. When the silage is first fed, some of the animals will refuse to eat because they are not accustomed. There are four ways: First, feed a small amount of silage before fasting, and feed other feeds. The second is to put a small amount of silage and concentrate feed
Feed after mixing, then feed other feeds. The third is to put the silage on the bottom of the feeding trough and put the feed normally fed on the upper layer so that the livestock gradually adapt to the smell. The fourth is to feed the silage and other commonly used fodder after mixing. On the basis of feeding, the amount of silage can be reduced from
More gradually increased.
2, to qualitatively quantify. Good quality silage can be fed more, otherwise it should be fed less. Finely silted silage is unfavorable for ruminating cattle and sheep, and should be fed together with high quality hay.
3, pay attention to feeding hygiene. Before each feeding, all the leftovers in the tank should be cleaned to avoid contamination of the new feed by the old feed and affect the appetite of the livestock. If ice builds up on silage during the winter, it should be thawed and then fed, otherwise it is easy to cause miscarriage of dams. Dairy cows should be fed silage after milking. Do not store silage in milking rooms to prevent them from affecting the smell of fresh milk.
4, to feed depending on species. Feeding silage can increase the milk production of dairy animals, and dairy cows and dairy sheep can feed more. Because silage contains a large amount of organic acids, there is a laxative effect, and it is advisable that the maternal stocks in late gestation should be fed less. Silage acidity affects the quality of breeding stock semen because
It is also advisable for such sire to feed less. The reference feeding amount of daily silage for various types of livestock is: cows 15 kg to 20 kg, beef cattle 10 kg to 17 kg, calves 3 kg to 5 kg, horses 8 kg to 10 kg, donkeys 5 kg to 8 kg, pigs 1.5 kg to 2.5 kg, sheep 1 kg to 3 kg.
