Which one is better to feed chickens with bran and soybean skin?

Grain bran is better, grain bran contains glutamic acid and phosphorus, they are indispensable components for chicken growth, and rice bran is not, rice bran hardness, poor taste, chickens don't like to eat, that's all I know.

Rice bran is the fine powder (fine bran) ground from the epidermis after the husk of rice is removed, and the mixture of three substances separated from the seed coat, aleurone layer and embryo when brown rice is processed into white rice is commonly known as rice bran. As in the case of wheat bran, its nutritional value varies according to the degree of rice processing, the whiter the processed rice, the more substances in the endosperm enter the rice bran, and the higher the energy of the rice bran. Grain bran is a by-product of millet processing.

In addition to the peel, seed coat and corn, there are also many expensive glume shells, so the cellulose content is high, accounting for only 8 grams of digestible protein per kilogram of dry matter, and it is the worst nutrient value in the bran feed. From the point of view of nutritional value, rice bran is better.

The nutritional composition of grain bran and rice bran is different, and the nutritional value produced by feeding it to chickens is also different.

Rice bran is the fine powder (fine bran) ground from the epidermis after the husk of rice is removed, and the mixture of three substances separated from the seed coat, aleurone layer and embryo when brown rice is processed into white rice is commonly known as rice bran. As in the case of wheat bran, its nutritional value varies according to the degree of rice processing, the whiter the processed rice, the more substances in the endosperm enter the rice bran, and the higher the energy of the rice bran. Rice bran contains crude protein, crude fat, crude fiber, and fresh rice bran has good palatability.

In terms of the quality of protein, the lysine content in bran feed is higher, accounting for:

The crude fat of rice bran is high in unsaturated fatty acids, so it is not easy to store and easy to soften rancidity. The riboflavin content is second to that of wheat bran. The ratio of calcium and phosphorus content is improper, and the two are respectively, and the ratio is 1:

22。Due to the high fat content, too much feeding can easily cause diarrhea. The above points should be paid attention to when preparing diets.

Soul match, I'm waiting for you on the other side.

Ad. From the perspective of nutritional value, rice bran is still better, and grain bran and rice bran cannot replace each other. Grain bran is a by-product of millet processing.

In addition to fruit peel, seed coat and barnyard grain, there is also a large amount of glume husk, so the cellulose content is very high, accounting for only 8 grams of digestible protein per kilogram of dry matter, close to coarse feed, it is one of the worst nutritional value in bran feed.

Rice bran. It is crude fiber with wheat bran, and it is not high in terms of nutritional value. For livestock farming, rice bran and wheat bran are mixed and used together with other feeds to reduce the economic expenditure of feed.

If the number of breeding is large, large-scale breeding, feed plus rice bran and wheat bran to feed, it will definitely not work, slow growth, slow effect, economic benefits are not cost-effective.

In rural areas, many rice bran is mixed and used together with wheat bran, because the amount of feeding is not large, and the slaughter is not in a hurry. Raise one or two pigs, raise them from the beginning of the year to the end of the year, and add cassava such as protein powder in the middle.

Basically, they are fed with rice bran and wheat bran throughout the year, and the pork raised in this way is delicious. Rice bran and wheat bran can also be used to feed chickens, but it takes a long time, and it always takes almost adult time to produce it, which shows that the nutritional content of rice bran and wheat bran is not high.

If rice bran and wheat bran are used for breeding, it is certainly not cost-effective for professional households. Even if it is farmed, rice bran and wheat bran must be fed with corn or cassava, so that it is easy to see the growth of livestock. Wheat bran has a higher nutritional value.

Rice bran and wheat bran are rice grains.

and a by-product of wheat processing, which usually contains more than 1% phosphorus and contains B vitamins.

Because of cellulose.

The content is higher than that of rice and wheat, the digestibility is lower than that of rice and wheat, and although the phosphorus content is more, 70% is phytic acid phosphorus, and the utilization rate of pigs and chickens can only be used for one-third.

Note that rice bran is a mixture of the peel, seed coat, outer endosperm, and aleurone layer produced when rice is refined. The quality and composition of rice bran vary according to the degree of rice refining, and the higher the degree of refinement, the higher the feed value. The products of rice processing are divided into rice bran, 19 bran, 28 bran, and 37 bran.

Bran and four or six chaff. The feed value of 19 bran, 28 bran, 37 bran and 46 bran is lower than that of rice bran. The nutritional value of 19 bran and 28 bran is the worst, and the feeding effect of pigs is not good.

If the amount of rice bran is fed to pigs is too much, soft fat meat will be produced, and fresh rice bran contains a lot of fat, which is easy to spoil when it is hot. Wheat bran is palatable, fluffy in texture, laxative, and is a good feed for late gestation and lactating sows. In general, feeding wheat bran is beneficial to improve the quality of pork, which produces white hard bodies.

Fat. Wheat bran.

The contents of crude protein and nitrogen-free extract were higher than those of fresh rice bran, and the crude fat and crude fiber were lower than those of fresh rice bran. Therefore, the nutritional value of wheat bran is higher than that of fresh rice bran.

Rice bran is better fed to chickens.

After treating rice bran with l% acetic acid instead of 20% corn and 100% lysine, it was found that the treatment group with acetic acid could improve the nutritional value of rice bran, and compared with the control group, the weight of the chickens in the rice bran treatment group increased by 20%, the feed conversion rate increased by 13%, and the liver and pancreas of the chickens did not show abnormal hypertrophy, and there was no erosion erosion.

Studies have also shown that supplementation of basal diets containing 25% and 50% of rice bran with xylanase activity can improve the performance of incoming and broiler chickens within 2 weeks of age. The basal diet of rice bran (containing 25%) was 18 91% (P<0 05) and 11 80% (P<0 05) higher than that of the control, respectively, after the addition of enzyme preparations, and then the effect decreased.

Functions of rice bran:

Rice bran can "open the stomach and open the stomach, lower the qi", and long-term food can make the human body "smooth the skin and body, and can be nourished". Relevant experiments have also proved that the dietary fiber in rice bran can promote the emptying of the gastrointestinal tract and is a good gastrointestinal "scavenger".

At the same time, dietary fiber is known as the "seventh major nutrient" and plays an important role in promoting digestion and absorption and enhancing gastrointestinal peristalsis. It can enhance gastrointestinal motility, effectively promote human metabolism, increase appetite, improve gastrointestinal environment, promote the timely discharge of toxins and wastes, so as to ensure the full absorption of other nutrients.

As early as in the "Yellow Emperor's Neijing: Su Wen", there is a discussion of "five grains for nourishment", in which the five grains are grains with bran.

The above content refers to People's Daily Online-Eat rice with a little chaff, and all the young and old are healthy.

Rice bran refers to a mixture of peel, seed coat and germ that is refined after rice hulling. According to the precision of processing, the quality is different, and some are doped with a small amount of chaff and broken rice. Due to the factors in rice processing, the moisture content is high, such as without dehydration treatment, it is not resistant to storage.

Rice bran is a good raw material for chicken feed, when the dry matter of rice bran reaches 87%, the crude protein content is about 13%, and the energy value is relatively high in the bran bran. Because the oil content in rice bran is high, more than 10%, and some up to 18%, most of the fat in rice bran is unsaturated fatty acids, which are easy for animals to absorb and utilize. However, this unsaturated fatty acid is prone to breakdown and spoilage, so the fresher the rice bran is used, the better.

Due to the instability of the unsaturated fatty acids in rice bran, which is easy to decompose and deteriorate, the storage time of rice bran should not be too long, not more than two weeks. If the water is large, it can not be put for a long time, and it is best to buy and feed now. In order to prolong the storage period, the degreasing treatment can be adopted, and the existing extraction method and pressing method can extend the storage time of the processed rice bran cake.

Rice bran, commonly known as green bran, is a mixture of peel, seed coat and germ removed in the process of brown rice processing plant, which is also mixed with a small amount of rice husk and broken rice. Rice bran contains 10%-18% crude protein oil, and is rich in vitamin B and minerals such as manganese, potassium, magnesium and silicon, but the content of vitamin A, vitamin C and vitamin D is less. Rice bran is a good feed for chickens, but the traditional usage is not reasonable and should be improved.

1. Appropriate amount. Feeding too much rice bran can fatten the chickens, which can reduce the reproductive performance of the breeders. In addition, because the higher content of phytate and trypsin inhibitors in rice bran is not conducive to the decomposition of crude protein, chickens will eat too much rice bran will be thin, therefore, the feeding amount of rice bran should not exceed 30% of the chicken diet, and should be reasonably matched with other fine, coarse and green feed.

2. Fresh. Rice bran has high oil content, and is susceptible to acidification and deterioration under the influence of high temperature, humidity, light and air during storage, which reduces the nutritional value and palatability of the diet, and may cause diarrhea in chickens. Therefore, aged rice bran that has been stored for too long should not be used to feed chickens.

3. Supplement calcium and phosphorus. Rice bran contains less calcium, can not meet the nutritional needs of chickens, although it contains more phosphorus, but mainly phytate phosphorus, can not be fully absorbed and utilized by chickens. Therefore, bone meal should be added to the chicken diet with rice bran, and chickens should be exposed to more sunlight at the same time to promote the absorption of calcium and phosphorus by the body.

Rice bran plus 60% corn flour added to the EM bacteria fermentation effect is better, can decompose crude protein, improve feed utilization, at the same time, EM probiotics into the chicken intestine quickly improve the intestinal digestive system to improve the system, at the same time, EM bacteria clean up the intestinal system has a good effect on the prevention of intestinal diseases.

The bran contains 14% crude protein, 4% crude fat, 12% crude protein of rice bran, 15% crude fat, 9% crude fiber, and the energy of rice bran is higher than bran.

If there is coarse grain flour, put some coarse grain flour and feed and bran and stir it well, and then put less than water and stir it to soak it thoroughly, not too thin!

Rice bran is stirred with leftover rice or leftover rice porridge and it is ready to be fed to the chickens.

Wheat bran chickens are more nutritious than rice bran chickens, because rice bran also has to do other feeds, rice bran alone is not nutritious, wheat bran is more nutritious than grain bran, and chickens are better.
