rice bran

Unhusked rice Is China's first major grain varieties. The current annual output of about 206 million T. Accounted for 42% of total grain yield. The world rice production accounts for 37% of the total grain output. In the rice processing into milled rice process to remove the shell and total about 10% of the pericarp, seed coat, perisperm, gooey layer and embryo, the traditional rice bran is the current national standard of rice bran is mainly composed of pericarp, testa, endosperm, aleurone layer and embryo processed, so in the process will sneak into dust a small amount of rice husk and a certain amount of microbes and so can be used as feed, is the main byproduct of rice processing. The domestic and foreign research results and data show that in rice bran is rich in nutrients and Physiologically active substances . Now the United States and other developed countries have come out of China's edible rice bran, has a similar product was invented, namely the application of modern food processing precision milling technology in rice bran does not benefit the food material (rice husk, pericarp, seed coat, dust, microorganism and food nutrients (Yi) embryo, paste powder layer outer endosperm) precision grinding separation in the clean production workshop, the separation technology can be classified into two parts of feed grade rice bran rice bran and rice bran food grade, food grade rice bran which Yuezhanmi total weight of 80%, more than 90% nutrition. Because the food grade rice bran although accounted for only 6% of the weight of rice, and accounted for about 60% of rice nutrition, is crushed under the rice milling process, so it is also called "Mizhen" or "rice meal".
rice bran

rice bran brief introduction

[meridian] into the spleen and stomach.
[effect] spleen and stomach, diuresis detumescence.
[indications] Beriberi , edema, diarrhea.

rice bran purpose

Due to the processing of rice bran raw materials and the processing technology of rice bran. Different components are not exactly the same. In general, the average protein content of 15%, rice bran fat 16%-22%, sugar 3%-8%, 10% moisture, heat is about 125.1KJ/g. The main fatty acids are mostly oleic acid, linoleic acid and other unsaturated fatty acid and fat, with a high amount of vitamins, plant alcohol, dietary fiber, amino acids and minerals etc.. Therefore, the nutritional components of rice bran can be extracted through further processing, such as tofu for extraction of riboflavin, calcium phytate, can be used to extract rice bran Rice bran oil . Defatted rice bran also can be used for the preparation of phytic acid, inositol and phosphate; tiny particles of yellow rice bran. To add to the bakery and other rice bran in fortified foods at the same time because of low content of soluble fiber. In the rice bran and rice bran wax, rice and sitosterol have lower blood cholesterol. Add the rice bran in animal animal feed instead of corn and other raw materials, reduce feed costs and improve the economic benefits of research reports and there are many, this paper makes a detailed application of rice bran nutritional function and production of livestock and poultry.

rice bran The role of nutrition

rice bran Laxative

In order to verify the Slavin and Lampe of rice bran and wheat bran laxative effect on regular diet healthy males were test results of edible rice bran, rice bran is effective to increase the amount of stool fiber. The reason is probably the rice bran in the carbohydrate in the gut and digestive enzymes, so as to add the same wheat bran and laxative effect.

rice bran Lower cholesterol

So far, the study found that rice bran contains many compounds and reduce cholesterol, but the existing data do not clarify each compound ability to lower cholesterol. 1991. Rukmini and Raghuram of rice bran oil to reduce the nutritional and biochemical effects of blood lipids were reported. The conclusion is: the main components of rice bran oil, such as Monounsaturated fatty acid , linoleic acid, linolenic acid and a small amount of non saponifiable components that together produce cholesterol lowering effect of rice bran oil.
Kahlon and Newman et al. Through the study of rats and chickens found in reducing blood fat, defatted rice bran rice bran as well. To determine the cholesterol fractions decreased in rice bran, it is needed to change with the whole blood and defatted rice bran for further study.

rice bran Reduce urinary calculi

The formation of urinary stones and urinary calcium excretion, researchers on a daily intake of 1 800rag calcium rich food women study, add rice bran, bean bran and wheat bran in the food can reduce renal calcium excretion, and renal oxalate excretion increased, but the most obvious effect of rice bran.

rice bran Other effects

The anticancer effect of skin care
Japan's Asahi University researchers through animal experiments found that rice bran contains ceramide glucoside has the melanogenesis inhibitory effect. It make cosmetics skin moist and white. Japan Wakayama County The industrial technology center from rice bran extract ferulic acid as a food additive, is effective in absorbing ultraviolet and prevent the oxidation of aromatic alcohols. The grass oil and citric acid in combination with EGMP, made of anti-cancer substances, can prevent colorectal cancer, safe and convenient.
The extraction of rice bran oil
Extraction of rice bran rice bran oil has been great development in our country, the rice bran oil is mainly unsaturated fatty acids, vitamin E, squalene, activity of lipase, sitosterol, sterol, stigmasterol and 3 kinds of ferulic acid ester antioxidant and solid plant components etc.. To reduce excessive cholesterol deposition in the vascular wall of rice bran oil, can be used for hyperlipidemia and atherosclerosis The prevention and control of. 3 kinds of ferulic acid in rice bran oil rich in antioxidants to an important role in the antioxidant stability, and adjust the body and function of the brain. There is a certain preventive effect on vascular headache and autonomic nerve functional disorder. The study also found that rice bran oil has sedative and hypnotic effect.
phytic acid
Phytic acid (Phytic acid) is the six cyclohexyl alcohol phosphate ester, in plants usually in the form of calcium phytate, up to 1% 10%~1 of calcium phytate content in rice bran, usually by extraction precipitation or ion exchange. The extraction of phytic acid from defatted rice bran, residue can be used as feed, Nutritive value High, Japan said that the extraction of calcium phytate after processing of rice bran rice bran as high protein, protein content can be as high as 25%.

rice bran The production and Application

For animal husbandry mainly includes rice bran rice bran and defatted rice bran, defatted rice bran refers to the extraction of rice bran fat in rice bran oil after rice bran, rice bran is generally in order to reduce fat rancidity. Prolonged storage period. Rice bran is rich in nutrients (Table 1), is a good energy feed, and the price is lower than corn and Wheat bran .

rice bran Poultry feed

Application in broiler feed
Lin Lishan will l% rice bran with acetic acid, instead of 20% corn and 100% lysine, found that acetic acid treatment can improve the nutritional value of rice bran, rice bran increased by 20% compared with the control group treated chicken weight, feed conversion rate increased by 13%, and the chicken liver and pancreas did not appear abnormal, too no erosion erosion. In general, the defatted rice bran and rice bran oil by adding the metabolizable energy value of the same, the feeding value of broiler is the same. But a lot of research results show that diets of rice bran using too much, the growth rate of broilers decreased significantly, feed conversion rate decreased gradually, thus to how much usage in the diet of rice bran, opinion is not consistent. The United States Martin (1983) test showed that diets with increasing amount of rice bran (0 ~ 50%), the growth rate of broilers curve down, but the use of rice bran content is less than 10%, the growth rate is no longer affected; for 0 - 21 days old broiler chickens, rice bran dosage in 5%, feed conversion rate increased. The feed conversion rate remained unchanged. Warren (1990b) such that for 21 to 49 day old broiler chickens, rice bran consumption is lower than 20% in the diet, feed intake is not significantly affected; and that in some other tests for broiler 10-49 day age, the content of rice bran in the diet in the range of 0-53.9%, feed conversion rate has no obvious change, but the growth rate slowed significantly. The research also shows that. Feeding 25% and 50% containing rice bran based diet with enzyme activity of xylanase. Can improve the 2 Weeks of age The production performance of chickens and broilers. According to test Wang Qingji, (including 25%) rice bran based diet supplemented with enzyme preparation after the chicken 7-14 and 14-21 day, the weight increased 18.91% (P<0.05) and 11.80% (P<0.05), then the effect is reduced.
The application in the production of laying hens
Tolerance of laying hens on the rice bran is strong in broilers. The use of rice bran than using defatted rice bran egg size, egg weight, egg drop. Najeewa (1980) found that the use of rice bran was higher than 45% in diets, egg production began to be affected, the mortality rate has increased. But due to the high linolenic acid content in rice bran, rice bran diets, egg weight tends to increase. Humid (1987) with two different levels of energy and protein diets found in laying hens. When the dosage of 38.5% rice bran. Compared with the amount of 18.5% rice bran dietary groups, although the same energy and crude protein levels slightly higher, egg laying hens, egg weight index were significantly decreased. There is a view that the addition of ZnC03 in layer diet, may be appropriate to increase the amount of rice bran diets.
Application of duck diets
Compared with the ducks in terms of laying hens, greater tolerance of rice bran, the effects of dietary in a larger proportion of rice bran on production performance is very small. A duck diet is rice bran of 45%. The test shows that. Adding phytase in feed ducks can make the feed conversion rate increased. In the diets of rice bran was 30%. Adding phytase to the total ash of tibia weight increased. In addition, Martin test also showed that the dietary supplementation of phytase in the best adding part of animal feed, so the content of rice bran in the range of 69% to determine the growth rate has no effect, and the whole plant feed will inhibit the growth of meat ducks. The test shows that some other. With the usage of rice bran diets increased, viscosity decreased intestinal chyme in duck. The Shen Baigen test with 30% rice bran, wheat enzyme or enzyme instead of 18 diets on meat duck 30%, corn, regardless of the ratio of feed to meat or increase the cost of feed unit weight, than corn diet good. So for breeding, rice bran should be an ideal source of feed.
Application of goose in feed
Ai Xiaojie added 30% rice bran in Gosling diets. At the same time, adding 0.2% enzymes, showed that enzyme preparation by degradation of xylan in rice bran diets and other anti nutritional factors, reduce the viscosity of digesta, can improve the body's digestion of nutrients in feed and absorption, accelerate the growth of goose; also found that enzyme in rice bran play a role in the body is relatively slow, requires a process. It was to avoid the ileum; hypertrophy and hyperplasia of digestive gland and digestive tract, promote the rapid growth of goose.

rice bran Pig feed

In pig diet appropriate collocation can reduce the feeding cost of rice bran meal. Early pregnancy sows was 20%~30%, 30%-70%, late 30%-50%; lactation 30-60 day old piglets to 30kg before, should be in the 5%-15%, if the amount is too much, the piglets do not eat, and will cause diarrhea; dosage of 10%-20%; 70kg 3070kg feeder pigs, more fattening pigs, the dosage should be in 20%-25%. The amount of less than 25%, which is equivalent to the feeding value of corn. The amount of more than 30%, the feeding value decreased, the pig began to picky eaters, loss of appetite, skin relaxation, and to reduce pig meat.

rice bran Ruminant animal feed

In recent years, with the increasingly fierce competition in the feed industry. A large increase in the number of dairy cows. Research and development of dairy cattle feed has become a technology research and the feed manufacturers are most concerned about the economy. Rice bran as ruminant animal feed raw materials rich in nutritional value is preferred. With the specific amount of dairy cows in different stages. Young cattle and dry milk cow amount more. The general use of dietary dry matter 30%-40%: cow varies with the stage of lactation, the general can use diet dry matter 15% - 30%. Of course, as a supplement concentrate beef, rice bran concentrate can be as the main supplement.
