Rapeseed is the main raw material for farmers to crush oil. The average 100 kg of rapeseed oil is 70-80 kg. The residue after oil extraction is also about 300 tons, which is called rapeseed cake. It is a good raw material for making feed. However, some of the rapeseed cakes contain toxins, which can cause animal poisoning and affect the palatability and applicability of rapeseed cakes. Therefore, it is necessary to detoxify the rapeseed cakes with the goldbeet rapeseed cake feed starter, after detoxification. The rapeseed cake is a good protein raw material for making feed, which can greatly increase the nutritional composition and palatability of the rapeseed cake.
Poisonous ingredients of rapeseed cakeThe toxins in the rapeseed meal are mainly sulphur glucoside and its degradation products, iso-sulphates, oxazolidinone, cyanide, sinapine, phytic acid, and tannins. According to the content of the toxin in rapeseed meal and the sensitivity of the feeding object and the product, the amount of the cooking cake in the beef cattle feed is controlled.
Detoxification treatment of rapeseed meal: After the rapeseed is destroyed and treated with hot water, the cellulose and lipoprotein suspensions are separated by a density metering sieve and then separated by alkaline centrifugation to obtain lipoprotein precipitates and waste liquid ( Mustard seeds enter the waste liquid).
Detoxification method of rapeseed cakeThe water washing method has been adopted abroad and the detoxification effect is good. The method of detoxification is to open a small mouth at the bottom of the cement pool or cylinder, install a false bottom, place the rapeseed cake on the false bottom, heat the water or cold water to soak the rapeseed cake, leaching repeatedly, and then drain the water. The waste water can be recycle and re-use. The principle is that the toxic components in rapeseed cake are soluble in water, especially in hot water. Commonly used continuous flow water and double water treatment methods. The continuous flow water treatment uses cold water to continuously flow into the rapeseed cake, continuously draining the water, keeping it for 2 hours, filtering, discarding the filtrate, and then immersing it in double water for 3 hours and discarding the filtrate. The detoxification rate can reach over 94%. The dripping method is to add the same amount of water to the rapeseed cake, soak it for 4 hours, then continuously add twice the water, and continuously drain the water. The dripping method not only saves water but doubles the detoxification rate. The water washing method has simple equipment, simple technology, easy operation and high detoxification rate, but the water washing method costs water and loses part of the water-soluble protein.
Second, Jinbao rapeseed cake fermentation detoxification method1. Crushing the material: First, we must remove the raw materials that have become rotten and spoil, and chop or crush the rapeseed cake. The rapeseed cake protein feed should not be fermented separately, and some corn flour, wheat bran and other energy feeds should be added for common fermentation.
2, diluted strains: the gold baby feed fermentation agent (thousandth) with corn flour, wheat bran and other diluted all sprinkled into the crushed rapeseed cake, to ensure that the materials are mixed;
3, control the water: The mixing of the material and add water, the material moisture content controlled at 60 ~ 65%. Judgment method: Hand grab a handful of material, fingers see the water does not drip, landing is scattered suitable, more water is not easy to warm, water less difficult to ferment.
4. Sealed fermentation: The rapeseed cake materials with good moisture content will be filled into cylinders, canisters, pools, plastic bags and other sealed containers. The materials should be completely sealed but not compacted when using tightly sealed containers. During fermentation, a plastic bag that can be tightly sealed should be added to the outside. Note that during the sealing process, the plastic bag must not be torn down and tossed. At a natural temperature, it is sealed and fermented for 2 to 3 days. When there is aroma or mud taste, it indicates that the fermentation is completed. Can be fed.
Third, the pit detoxification methodWith simple and low cost, the thioanilide detoxification rate can reach over 90% to 97%. The oxazolidinethione residue is only 60×10-6, and the detoxification rate can reach over 99%. The protein loss rate is only about 1%. The specific method is: digging 1.0m in dry arable land and 1.5m in depth, the length of which depends on the number of cakes. Usually 1m3 can be buried rapeseed cake 500kg. Before loading the pits, add the same amount of water to the rapeseed cake, cover the mat with the bottom of the pit, fill the mat with the pit, or cover the straw with a 0.3m thick soil and bury it for 2 months. The principle is that the sulfhydryls are decomposed by the decomposition of various microorganisms in the soil, on the cake, in the air and in the water under anoxic conditions. The related enzymes in the cake are also revitalized and the decomposition products are slowly adsorbed by the soil. The detoxification rate of this detoxification method is related to the soil moisture content. The soil moisture content is 5%, and the detoxification rate can reach over 97%. When the soil moisture content is 20%, the detoxification rate is only 70%.
There are many methods for detoxification of rapeseed cake. In contrast, the detoxification method of fermented fish treasure is easy to learn. And the fermented seaweed cake feed greatly saves the feed cost of the farmers, and can also improve livestock immunity, deodorize and fly, improve meat products, etc., further promote the digestion and absorption of livestock, and help livestock grow quickly and healthily. To maximize the economic benefits of farmers.
