The rainfall in the northeast region continued. Many readers called the newspaper to report that the phenomenon of mildew in feed due to high humidity was very common. Mildew reduced the nutritional value of feed and affected palatability. What's more serious was causing feed. The product mycotoxin exceeded the standard, and after light dieting of livestock and poultry, it affected growth and development, and severe poisoning caused death. This not only caused major economic losses to farmers, but also endangered human food safety. For mild mildewed feeds or raw materials, they may be used in combination with other feeds after treatment, and should not be used as the "main food" of livestock and poultry; for highly mildewed feeds, it is better to dispose of them because of the high treatment cost. There are the following methods for the treatment of moldy feeds: The culling method is applicable to the straw and pellets. Once mildew occurs, the moldy and deteriorative parts can be removed directly. Washing method is applicable to the seed feed Seed feed mildew, moldy feed can be crushed, pour into the tank, add 3 to 4 times water and mix well, then change the water twice a day, until the soaked water from the tea color Become colorless. The drying method is suitable for a large amount of straw feed and is mainly used for a large amount of straw feed. The method is to first put the moldy feed to dry in the sun, and then ventilate and shake loose to remove mold. The heating method is suitable for the cake type raw materials For the cake type raw materials, baking at a temperature of 150 DEG C for 30 minutes, or heating in a microwave oven for 8 to 9 minutes, the aflatoxin therein can be destroyed by 48% to 61%. The de-embryo method is suitable for the corn mold feedstuff. After moldy corn, the toxins are mainly concentrated in the embryo. First grind the corn into small particles with 1.5~4.5mm in diameter, add 5~6 times of water, and then stir. The embryo fragments will float on the water because they are light, remove it or drain it with water. Times, you can achieve the purpose of detoxification. Lime-water immersion method is suitable for corn, sorghum seed feed, suitable for corn, sorghum and other seed real feed. The method is to first comminute large-grain and moldy feeds such as corn into small granules with diameters of 1.5 to 5 mm (small grains such as sorghum are smaller, without crushing), and lime powder after 120 mesh sieve is mixed with moldy feed at a ratio of 0.8-1%. In the middle, the lime powder and water mixed into the container are then poured into the container at a ratio of 1:2 and stirred for 1 minute. After standing for 5 to 8 hours, the water is poured out and rinsed continuously with fresh water for 2 to 3 times. Can use it. According to data, adding 5% quicklime to mildewed feed can remove 90 to 99% of the toxins. The ammonia method is suitable for bran feeds suitable for bran feeds. The method is to use 12.5 g of ammonia per kilogram of feed. Stir in the container and seal with a plastic sheet. The detoxification rate is 87.5% at room temperature and 20°C for 7 days. The detoxification rate at 90°C and 5 days at room temperature is 90. %the above. Alkali cooking method is suitable for seed feeds. It is mixed in a proportion of 100 kg of moldy feed plus 3 times water and 500 grams of soda powder (or 1 kilogram of lime). Cook until the feed is cracked and wait for it to cool. Rinse with water to remove alkali. Adsorption clay and zeolite (its main component is aluminosilicate) can not only promote the growth and development of livestock and poultry, but also has a strong adsorption. Add 0.5% of clay or zeolite in feed, can adsorb mycotoxins in feed. . The fermentation method utilizes lactobacillus for fermentation, and the toxicity of aflatoxin is reduced by the action of enzymes. Using this method to treat feed not only reduces the toxicity of mycotoxins in feed, but also increases feed nutrition (mycelial proteins) and improves palatability. Farmer friends can also choose mold inhibitors to prevent moldy feed. There are many types of feed anti-mould agents, and the most widely used ones are propionic acid and its salts. Propionic acid has better mildew resistance than its salts, but propionic acid has a corrosive and pungent odor. Ammonium dipropionate has an antiseptic effect similar to propionic acid and overcomes the disadvantages of propionic acid which is corrosive and pungent. In addition to the use of a single type of anti-mold agent, the current trend of the international use of anti-mold agents is the use of composite anti-mold agents, which are formed by combining a certain proportion of organic acid anti-mold agents. This compound anti-mold agent can broaden the scope of antibacterial spectrum and enhance the anti-mold effect. Greenhouse Drip Irrigation System Fertigation is using your irrigator to fertilise the plants and soils as you water, which is the most efficient and advanced practice of fertilization. Aid of pressure system (or natural divide terrain), the soluble solid or liquid fertilizer, according to the soil nutrient content and crop fertilizer regularity and characteristics of species, with the fat of with irrigation water, through a controlled water supply pipeline system, supplying, the compatibility, water through the pipe and drop head form drip irrigation, uniform, regular, quantitative, infiltration area crop root growth and development, make the main root soil always stay loose and appropriate moisture content, at the same time according to different crop fertilizer characteristics, environment and soil nutrient content in soil; Crops in different growth phase water requirement, the different development stages of the fertilizer rule is the demand of design, the water and nutrient timing quantitative, provided directly in proportion to the crops.
