Reasonable use of livestock manure

Livestock and poultry manure contains a large amount of undigested protein, B vitamins, mineral elements, crude fat, and a certain amount of carbohydrates. After processing, it can become a good feed resource. However, at the same time, livestock and poultry excrement also contains more water and various bacteria, and only deodorization and dehydration can increase the value of use and facilitate storage. Now introduce several commonly used processing methods: First, the drying using natural drying method, the fresh livestock and poultry manure spread on the cement floor or plastic cloth, flip at any time, let it dry naturally, and then crush and feed into other feeds. Second, silage silage method is the most simple, effective and perfect. As long as there is sufficient water (40% to 60%) and soluble carbohydrates, animal manure can be silted together with crop residues, forage, crop straw or other roughage. When silage, the best ratio of animal manure to forage or other feed is 1:1. The following formulas are available for reference: cow dung 30%, chicken dung 25% to 30%, rice bran 5% to 15%, clover 15% to 20%, bean cake 5% to 10%, chaff 1.5% to 2.0%. If silage soluble carbohydrates are insufficient, add 9% to 12% of cornmeal or 1% to 3% of honey. The digestibility of fiber components can be achieved by adding alkaline substances such as sodium hydroxide, potassium hydroxide and ammonium hydroxide. improve. Because the silage method can improve the palatability and absorption rate, the silage of livestock and poultry manure is higher than the dry manure. Third, the fermentation of natural fermentation: the fresh chicken manure and bran in a 3:2 ratio or mixed with the broken barley and the other half, the moisture control at about 50%, into the sealed storage in the silo, the temperature is maintained above 5 Â°C, 20 ~ Open the cellar after 40 days. 57% of cow dung without straw and 43% of chopped hay were mixed and put into the feed tank to seal and ferment. Stacked fermentation: First, collect the fresh chicken manure, and then pour it into the cylinder, bubbling open, stir, remove the upper impurities and the lower sediment after the precipitation, take the middle layer of pure chicken manure, drain the water. 10 to 20 grams of yeast tablets, 15 to 20 tablets of sugar, and 5 to 6 tablets of oxytetracycline per 10 kilograms of chicken manure, 5 to 6 hours for stacking, and 20% for pigs if they are used to feed pigs. . Plastic bag fermentation: drying the livestock and poultry manure to 70% dry, incorporation of 10 to 20 kg of bran or rice bran per 100 kg, mixing and filling in a non-toxic plastic bag to seal the fermentation. The temperature is controlled at about 60Â°C, summer Fermentation for 1 day, spring and autumn fermentation for 2 days, the fermentation standard can smell sweet wine odor. Fermented feces can be mixed with 60% to 75% of other feeds to feed pigs. For long-term storage, the fermented feces can be dried (moisture tank cylinder fermentation: remove livestock and poultry excreta, dried, chopped, add water (Humidity is pinched into groups, fingers are not suitable for dripping), mixed with washed green fodder, pressed into the cylinder, and the surface is sprinkled with 2 cm thick bran or glutinous rice. The cylinder mouth is sealed with a plastic film. , Placed in a cool place (in winter, indoors), kept at about 20Â°C, after 10 to 15 days of fermentation, it is suitable for the sour and palatable feed. In the specific use, the suitable proportion of chicken manure to feed the pig is: the growing period accounts for the total diet The amount of 5% to 10%, the finishing period accounts for 10 to 20%, has no significant effect on the weight gain of pigs, but the economic effect is more ideal. Chicken feces should not feed young pigs, fattening pigs do not feed chicken feces before the first half of the slaughter Because chicken manure has adverse effects on the fat quality of carcass, the digestibility of dry matter, organic matter and nitrogen of the pig manure is 50%, 51% and 23%, respectively. Strains, made from fermented feed directly to pigs, amounting to 20% to 40% of the diet, saving feed costs by 20% Whether it is fresh or dry feed, cow dung is best sealed and mixed with other feedstuffs, so that the palatability is good.The fermented cow dung can be added in the cattle's diet by 50%.The cow dung is silaged together with the wheat straw to feed the sheep. It is better to dry the cow dung or treat it with formalin. The amount of cow dung fed is 10%, and its feeding effect is the same as the same amount of alfalfa meal. Note: (1) Feed chicken dung Beef cattle, when the chicken manure accounts for more than 40% of the dry matter of feed, should pay attention to use with the energy feed; (2) pay attention to phosphorus supplementation when using the laying hen chicken manure, (3) sheep is more sensitive to copper, with When chicken manure is fed to sheep, the amount of steel must be determined so that the level of copper in the diet will not exceed the tolerable amount, otherwise it will lead to poisoning; (4) The content of fiber in cow dung is high, when cow dung is used to feed pigs and chickens Do not add other high-fiber, low-energy feeds.
