How to make green storage feed for sheep raising, how to make green storage feed for sheep Simple pr

Provide a complete set of green storage technology, the most important thing is to exhaust the air and seal it tightly.

1. Harvesting of corn stalks: Whole plant corn straw silage is generally harvested at the maturity period of corn seeds. After harvesting the corn stalks, generally when the corn cob is ripe to 70% full, the leaves have not yet withered or 1---2 leaves at the base of the corn stalk begin to wither and yellow, and the corn cob will be harvested to make silage on the day of picking the corn cob.

Harvesting of forage grasses: Leguminous forages are generally harvested from budding to the beginning of flowering; Poaceae forage grasses are generally harvested at the time of booting to the beginning of heading; Sweet potato vines and potato stems and leaves are generally harvested 1-2 days before harvest or before frost. After harvesting, young pasture grass or weeds can be dried for 3-4 hours (south) or 1-2 hours (north closed attack square) and then silage, or mixed with corn stalks.

2. Cutting Zen letter crushing: In order to facilitate bagging and storage, the raw materials must be chopped, and the straw of corn stalks, string leaf rosin straw or chicory must be chopped to a length of about 1-2cm before silage, and the silage can be compacted. The grass and vines are soft and easy to compact, and the silage is better when chopped about 3-5cm.

3. Add starter culture: When using such as gold silage starter culture, the starter culture, nutrients and water should be 1:1 first

The ratio of 8 is made into an activation solution, and then mixed with water to make a dilution; Spray the activated golden silage fermentation broth on the straw (the laying of the straw and the spraying of the diluent should be uniform, and in the process of spraying and compaction, it is necessary to check whether the moisture content of the storage material is appropriate at any time, and whether it is uniform everywhere);

4. Packing: The bag mouth must be opened in the bag method, and each bag of silage raw materials should be packed into a special plastic bag, pressed by hand and pressed tightly with feet, until it is filled to about 30cm away from the bag mouth, and then pumped, sealed, and tied tightly.

1. Harvesting

When harvesting, the corn stubble is left 20cm, on the one hand, to prevent the microorganisms in the soil from entering the silage, causing the reproduction of clostridia, and on the other hand, the roots have too much lignin, which affects the digestion of dairy cows. The dry matter content for the best harvest is 30%-35%, and the maximum can not exceed 40%, and the most suitable moisture content for the growth of lactic acid bacteria is 65-70%.

2. Chop

The shredding is easy to step on and expels air. Pig silage should be 1 2 cm, and cattle and sheep silage should be 4 6 cm. Remove moldy, sedimentary or unclean, aged feed before shortening.

3. Spray the bacteria

Spray silage while packing and compacting. Fermentation of one ton of raw materials requires 1 kg of fermentation broth to ensure that the moisture content of raw materials is 60-70%, and the following Qiaopei takes 10 tons of silage as an example.

At the beginning of silage, aerobic microorganisms such as yeasts, spoilage bacteria, and molds attached to the raw materials are rapidly multiplied by the sap rich in soluble carbohydrates discharged by plant cells due to mechanical pressing. Spoilage fungi and molds multiply the most strongly. The addition of special bacteria such as gold silage can quickly consume the oxygen in the storage cellar, reduce the aerobic fermentation time, and form an anaerobic environment as soon as possible, so that the silage can enter normal fermentation.

Fourth, the cellar

When loading the cellar, it is compacted every 15 cm, paying special attention to the surrounding areas and corners of the silage cellar. From the end of the silage cellar or the middle to 30 degrees of slope layer by layer, while filling and pressing, layer by layer compaction, walking to take a straight line to flatten, and then diagonal compaction, must be pressed to the edge, the top into a hilly shape. If the vehicle cannot fully approach the edge of the silage cellar during the compaction process, personnel need to press on the edge.

Fifth, the main points

Shortened raw materials should be immediately filled into the cellar, the speed should be fast, silage is a very time-sensitive work, after the storage of a cellar, should be quickly sealed. Avoid the loss of moisture and nutrients in the sun for a long time, and avoid the elongation of the silage process, so that the raw materials will heat up and deteriorate in the cellar.

Sheep can not eat all the green storage feed, which will lead to slower growth rate and longer slaughter time, thereby increasing the cost of breeding. When raising sheep, you can use green storage feed and concentrate feed according to a certain proportion of feeding, fattening period each sheep can eat green storage feed 3 kg and concentrate feed about 3 pounds per day, can improve the growth rate of sheep.

<> captive sheep can be fed green storage for a long time, but the growth rate will be slower. Enclosure bucket sheep feeding feed needs scientific proportioning, in order to meet the needs of sheep growth, speed up the slaughter time, in addition to green storage material, but also need to add ear into the concentrate feed and minerals, concentrate feed can be soybean meal, peanut cake, sunflower cake, rapeseed meal, etc., minerals can be used Changzibu dicalcium phosphate, stone powder, bone meal, etc.

1. Preparations.

1. Dig a rectangular pit 10 meters long, 3 meters wide and 2 meters deep into the ground, and seal the bottom and surrounding areas with cement to prevent air and water seepage from the underground, and make "underground preparations" for sealing.

2. After the cement trough is cooled, cut the dry corn straw into 1 cm and 3 cm segments with a hay machine, and the humidity is held into a ball by hand, and there is no dripping water in the finger seams.

2. Fermentation work.

1. Scatter the cut straw into the cement tank, evenly disperse a layer of urea every 40 cm thick straw layer, and compact each layer with a solid foot.

2. After the straw fills the cement tank, seal the top with plastic sheeting, and bury it tightly with soil around it. After the sealing of the straw should try to avoid the sun, rain, in the winter can be considered in the indoor or plastic greenhouse, the most suitable temperature for fermentation is 10 30, 4 days 7 days in summer, 10 days 15 days in winter.

3. Feeding work.

1. When the straw feed has an obvious mellow and sour aroma, and the texture is soft and moist, it can be used.

2. Take as much as you want, and still seal it after use. Fermented straw can maintain its freshness for 1 to 2 years at a time.

3. Mix into the feed at a rate of 60%.
