Technical operation scheme of raising cattle by ammoniation of straw

The ammoniation of corn straw can be more effectively used by beef cattle and play a more effective fattening effect. Compared with single straw feeding, ammoniation not only improved the fattening effect of beef cattle, but also reduced the incidence of digestive system diseases of beef cattle.

? First, the selection of fattening cattle is mainly yellow cattle, followed by other breeds, and the selection of fattening cattle mainly pays attention to the following aspects.

Age. It is more appropriate to choose 2Mel 3-year-old young cattle.

health. Choose those who are in a good state of mind, walk forcefully, have good eyes, and eat a good diet. After artificial insemination, the hybrid generation has the advantages of rapid growth, high feed utilization rate, high slaughtering rate and good meat quality.

? 2. Characteristics and production methods of ammoniated feed

(1) characteristics of ammoniated feed

The so-called ammoniated feed is called ammoniated feed after the crop straw is sealed by chopping and ammonia for 15 days. It has the characteristics of high nutritional value, easy digestion, easy storage and good palatability. it not only maintains all kinds of nutrients of the original feed, but also contains a large amount of free ammonia, which is absorbed and utilized by livestock after the synthesis of bacterial protein by rumen microorganisms. Ammoniated feed is mainly suitable for ruminants such as cattle and sheep.

(2) preparation of ammoniated feed

The straw used to make ammoniated feed are: wheat straw, corn stalk, bean stalk, forage grass and so on. Urea is the main source of ammonia, and the production method is as follows: using 5kg urea according to 100kg straw, adding 60ml 80kg water, spraying evenly on the straw, finally loading it into the ammoniation pool, compacting layer by layer, sealing with plastic film, and requiring to prevent the sun and rain. After 15 days of fermentation, the ammoniated feed can be taken out and fed with ammonia. The time of ammonia discharge is generally 6m / m / 12 hours, and ammonia should be fully injected to prevent ammonia poisoning. At the first feeding, a small amount of feed should be given, and then gradually increased.

(3) the construction of ammoniation pool: the ammoniation pool can be built outdoors or indoors; it can be built above ground, underground, half above ground and half underground, and farmers can decide according to specific conditions, according to a fattening period of 130 days for cattle, which requires 2 tons of feed. It is appropriate to build 2 cubic meters of ammoniation pool for each fattening cow. A round hole with a diameter of 3 cm should be left at the bottom of the pool. Easy to clean and discharge. After the pool is bricked, the inner wall can be flattened with high-grade mortar, and the edge of the pool must be made with a sealing groove.

The occurrence of disease can reduce costs and increase economic income. Pay attention to prevent cold and keep warm in winter, avoid heat in summer, provide clean drinking water, pay attention to the hygiene of cattle and stables, often supply additives, make a reasonable collocation of coarse, fine and green fodder, and one fattening cow should not be less than 1 kilogram of concentrate every day. only in this way can we meet the needs of cattle for various nutrients.

According to the technical requirements of veterinarians, regular vaccination of cattle against foot-and-mouth disease and cattle failure can put an end to the occurrence of infectious diseases and ensure the healthy development of fattening cattle. At the same time, attention must be paid to the changes in appetite of cattle at any time. If abnormal changes in appetite are found, the cause should be found out immediately for diagnosis and treatment. Sheep enter the school
