First, access method
When opening the pit, first remove the mud and debris from the pit cover. The rectangular cellar should open from one end of the upwind and take the material in a cross-section, taking at least 6 to 7 centimeters per day. After taking the cross-section to maintain horizontal and vertical, can not be cut in the form of holes to dig deep, so as not to expose the surface, the temperature caused by high secondary fermentation. The circular cellar should be taken from the surface layer by layer, so that the silage is always kept on a flat surface, and it should not be taken from one place to the next. Regardless of the type of cellar, the exposed face cover must be tightly sealed with plastic sheeting after every refeed to make it airtight. Take the amount to use the principle of the end of the day, when the weather is hot with follow-up to ensure that feed fresh.
Second, pay attention to feeding livestock
Silage is of high quality and juicy, rich in nutrition, strong in palatability, and the animal prefers food, but if it is not scientific, it will be difficult to receive good results. One must be patiently fed and gradually transitioned. When the silage is first fed, some of the animals will refuse to eat because they are not accustomed to it. This requires the use of domestic animals. There are four methods: (1) Feeding a small amount of silage before fasting for hunger in the livestock and feeding other feeds. (2) Mixing a small amount of silage with concentrate before feeding, then feeding other feeds. (3) Put the silage on the bottom of the manger and place the feed on the upper layer so that the livestock gradually adapt to the odor. (4) Stir the silage with other commonly used fodder and feed it. Based on the practice of feeding, the amount of silage can be increased from small to large. The second is qualitative quantification. Good quality silage can be fed more, otherwise it should be fed less; squeezing too fine silage is unfavorable for ruminating cattle and sheep, and should be fed with high quality hay. Third, pay attention to feeding hygiene. Before each feeding, all the leftovers in the tank should be cleaned to prevent the new material from contaminating the old material and affecting the appetite of livestock. If the ice is frozen on the silage during the winter, it should be thawed and then fed, because the frozen silage can easily cause miscarriage of the dam. Milk cows should be fed with silage after milking, avoid silencing of silage during milking to avoid affecting the smell of fresh milk. The fourth is depending on animal species. Feeding silage can increase milk production of dairy animals. Dairy cows and dairy goats can feed more. Because silage contains a large amount of organic acids and has laxative effects. In order to prevent miscarriage, the female animals in late pregnancy should be fed less. Similarly, due to the fact that the acidity of the silage exceeds the level of the semen quality of the breeding stock, it is advisable that the broiler should also feed less. The reference feeding amount of daily silage for various types of livestock is: cows 15 to 20 kg, beef cattle 10 to 17 kg, calves 3 to 5 kg, horses 8 to 10 kg, donkeys 5 to 8 kg, and pigs 1.5 to 2.5 kg. Sheep 1 to 3 kg. Fifth, we must balance supply throughout the four seasons. Silage storage is not subject to seasonal restrictions and can be supplied throughout the year. For some large-scale cattle and sheep fattening farms that unconditionally graze, there must be sufficient silage and a balanced supply for the four seasons.
