In the processing of rice into rice, shells and seed coats and embryos that account for about 10% of the total weight are removed. Rice bran is processed from seed coats and embryos and is the main by-product of rice processing. Is the outer shell of rice, generally yellow. It is by shelling rice. Processing rice by-products. It is also a common feed for farmers and some pig farms. Crude protein content is about 13% when dry matter is 87%, and the energy value is also relatively high among widowers, because the oil content in rice bran is high, more than 10%, and some Up to 18%. Most of the fats in rice bran are unsaturated fatty acids, which are easier for animals to absorb and use.
One, the shortcomings of rice bran as a feed
1. The crude fiber of rice bran is about 9.4%, which is 5.7 times of that of corn. Due to the high content of crude fiber, pigs are not ruminants and cannot digest feeds that use high crude fiber. If they are not prepared, the pigs will overeat or replace them. Feeds can cause pig constipation.
2, rice bran is mainly coarse fiber, rough texture, there is a very dense small thorn outside the shell, poor palatability.
3. The unsaturated fatty acids contained in rice bran are easily decomposed and deteriorated and should not be preserved. Therefore, the use of rice bran should be as fresh as possible. It is best not to exceed two weeks, and even more water can not be put for a long time, it is best to buy now with the current feed
4, rice bran contains higher phytate and trypsin inhibitors, can affect the pig's absorption and growth of crude protein. Therefore, in the use of pig feed to master the amount. Adding too much piglets has diarrhea.
5. When there are too many rice bran (more than 35%) in the pig feed, it will inevitably consume more digestive juice and cause waste of digestive juice. It will also affect the absorption of other substances. For example, some digested foods are easily adsorbed by excess rice bran, resulting in the inability of the intestinal mucosa to absorb. At the same time, rice bran is coated on the mucosal surface, which affects the absorption of other substances. This will not only make excess Rice bran cannot be completely absorbed, and it also causes waste of other feed resources.
In summary, the rice bran has a high nutrient content, but it also has many shortcomings, but it cannot be added. We can use fermentation methods to mix other materials. After the anaerobic fermentation process is sealed by the Jinbao feed starter, it can significantly improve the quality of rice bran. Disadvantages.
Second, the advantages of fermented feed
1, easy to store. The rice bran fermented with the gold baby feed starter is generally guaranteed to be sealed for 1-2 years or even longer.
2, good palatability. The texture of the feed fermented with the gold baby feed starter becomes soft, and has the smell of sour liqueur, the palatability is significantly increased, and the appetite of the livestock is enhanced. General intake increased by about 20%.
3, consumption absorption rate increased. During the fermentation process, the cellulose and lignin of rice bran were partially degraded, and the composite structure of cellulose lignin was broken. In this way, the rumen microorganisms can fully contact with the fibers, promote the activity of rumen microbes, increase the synthesis of rumen microbial protein and volatile fatty acids, and increase the nutritional value and digestibility of rice bran. The fermentation process is the process of decomposing and pretreating the rice bran, which increases the moisture content of the rice bran. The fermentation causes the macromolecules in the rice bran to be decomposed into small molecular substances through fermentation of the golden bacterium microbial bacteria, so that the rice bran feeding process does not affect the absorption of other substances. Use and constipation and other drawbacks.
4, high nutritional value. The metabolic fermentation of golden baby microbial bacteria in rice bran will produce a large number of metabolites, such as organic acids, lactic acid, amino acids, etc., will be directly absorbed and utilized by pigs, greatly improving the utilization rate, while bacterial growth and reproduction generate bacterial protein, increase feed The absorbable protein content.
5, reduce disease and improve the intestinal environment. Jinbao microbial fermentation starters are all beneficial microorganisms. After the fermentation of the Golden Baby microbial feed also contains a large number of beneficial microorganisms. After being eaten by pigs, the beneficial microorganisms inhibit the harmful microorganisms and maintain the intestinal beneficial microorganism environment through the advantages of the population. , thereby improving feed utilization and reducing disease occurrence.
Third, feeding precautions Fermented rice bran is good, but it also requires us to rational feeding, gold baby feed fermentation agent is not a panacea, we can only use a reasonable use, to get the maximum profit, so we have to pay attention to the following operations .
1, the ratio can not be too high. Rice bran is a substance with high content of crude fiber and lignin. Pigs are not ruminants. Fermentation will not completely degrade cellulose and lignin and will only partially degrade. Therefore, we must not add too much rice bran. In general, blend the other ingredients in the following proportion:
Sows in pre-pregnancy, the amount of 20% -30%; medium 30% -70%; late 50% -30%; breastfeeding 30%.
For 60-day-old piglets, it should be between 1% and 5% at 30 kg. If the amount is too much, the piglets do not like to eat and can cause diarrhea.
30-70 kg shelf pig, dosage 10%-20%.
More than 70 kg fattening pigs, the amount should be 20% -25%. Within 25%, the feed value is equal to that of corn; when the amount exceeds 30%, the feed value is reduced.
2, the fermentation materials pay attention to nutrition. In addition to adding rice bran, it is necessary to add corn flour, bran, bean dregs, or soybean meal, rapeseed cake, glutinous water and many other materials. This will not only provide comprehensive nutrition and facilitate balanced nutrition for pigs, but also ensure that the feed produced by fermentation is effective.
3. Fermented feed is fed in proportion. Although the fermented feed is high in nutrients, it cannot be compared with full-price feeds. It is recommended by Kinrob that the fermented feed should account for 50% of the original feeding amount, and the maximum amount of raw feed should be 1 to 1 when compared with the full-price feed or the original feed. Mix after proportioning.
4, if you need to add trace elements, can be added after the fermentation before feeding, try not to add before fermentation.
5, gradually increase the amount of feeding. It is advisable to follow a gradual and gradual approach when feeding a well-fermented feed. If you suddenly add a lot of feed, sudden changes in the feed may cause an undesirable situation such as anorexia, overeating, diarrhea, or constipation in a short period of time. Therefore, it is better to use fewer points when starting to use the pig. Only gradually increase after adjustment. The maximum amount added should not exceed 50% of the amount fed.
