Do you have to feed chickens with corn flour and rice bran?

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.

It is necessary to add some water and stir it to make it easier to swallow and also conducive to balanced feeding.

It is good to feed the bran to the chickens, but pay attention to the amount used.

After treating rice bran with 1% 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.

Generally speaking, if the metabolic energy value of defatted rice bran and full-fat rice bran is the same by adding fat, the feed value of broilers is also the same. However, a large number of studies have shown that the excessive use of rice bran in the diet will significantly reduce the growth rate of broilers, and the feed conversion rate will gradually decrease, so the amount of rice bran used in the diet is very inconsistent.

Feeding method:

1. Chick stage, just bought or hatched chicks, 1 3 days can not be fed with rice bran, at this time the chick digestive system is poor, can only be fed some small particles of feed or corn flour. After 3 days, you can add some rice bran that has been crushed by the grinder to the feed, cornmeal, and bran flour.

2, chicken stage, can be fed daily in a variety of feed to add 50% of rice bran, because this stage is the chicken physique growth period, need to feed feed with relatively high protein content, can add corn flour, peanut bran powder, fish meal, bone meal and other mixed feeding, so should not add too much rice bran.

3. The fattening stage of big chickens, which is a critical stage, depends on it for chickens to grow fat and big in a short period of time; At this stage, the captive or free-range chickens must be converted into cages, and the cages of the chickens must be divided into grids respectively, and the width of each grid area is not too large, as long as the chickens do not step on the chickens can be replaced, each grid is 5 8;

From morning to 5 o'clock in the afternoon, sliced sweet potatoes are cooked and mixed with rice bran to feed the chickens; After 5 o'clock in the afternoon, switch to fry white rice with cooking oil, and then mix rice bran to feed chickens, the amount of rice bran can be used to 70 80%, raising for about 30 days, in this short 30 days, the caged chickens can grow fat and big.

Summary. It is okay to feed the chickens with corn flour and rice bran, but provide plenty of water at the time of feeding.

It is okay to feed the chickens with corn flour and rice bran, but provide plenty of water at the time of feeding.

Foods such as corn flour and rice bran can of course be dry fed to chickens. If you scatter the corn flour and rice bran on the ground, you can see that the chicken will eat it with its mouth. However, when feeding corn flour and rice bran, it should be noted that dry food like this good plum peel cannot be fed alone, and it needs to be combined with sufficient water.

Dry food friends can easily cause thirst and lack of water in chickens, which will affect the digestion and absorption of the stomach and intestines. So if you can, it's better to go with water. If you want to use water when feeding corn flour and rice bran, you can use raw water.

According to many years of breeding experience, of course, it is better to raise free-range. Captive chickens are easy to manage because they only live in a fixed place, and the number of chickens raised is also relatively large, and it is easy to cause large-scale collective trembling and illness. In the case of free-range farming, feed costs are reduced because the chicks can forage freely.

Generally, all the chickens will be driven back to the chicken coop at night, so that the chickens can rest safely and comfortably. Free-range chicks can run freely in the vast land, which promotes chick exercise and improves the body's immunity to a certain extent. The manure of free-range chickens can provide fertilizer for trees, etc., and some fruit trees such as cherry trees can be planted to increase by-income.

There are two tricks:1. Feed chickens with more new corn. 2. Feed with corn mixed with other feeds.

Reason:

Maize is a late-maturing physiological crop, and the content of resistant starch in new maize is the highest, and the content will gradually decrease after a period of storage. Due to starch denaturation, the amylose content increases, which has a certain effect on digestibility. It can have a negative impact on chickens.

Corn-fed chickens don't grow as fast, but they are more hydrated. The feed is nutritionally complete, and the chicken grows well, but has a high water content.

1. You can't only feed chickens with corn, corn is energy feed, protein content is less than 10%, vitamins, trace elements are also lacking, long-term single feeding corn, chickens will be malnourished, production performance will be significantly affected, if you still can't understand, you just imagine what it would be like if people only eat corn. How to solve it? Add protein feed raw materials (such as soybean meal, cotton meal, etc.), compound premix, bran, according to the nutritional needs of chickens at different stages (chicks, young chickens, laying hens, etc.), prepared into full-price feed, so that chickens can eat feed that meets all their nutritional needs, production performance can be fully exerted, but also enhance immunity, reduce the rate of illness and death, if it is a laying hen, it can also improve the egg production rate.

2. Choose qualified corn. For example, corn can not have mildew, corn moisture content can not exceed the standard, corn can not have foreign matter, corn kernel full and broken rate to meet the standard. Also, try not to buy aged corn that has been aged for too long.

5 tips for feeding chickens with corn, it's very fragrant.

3. Feed chickens with fresh corn step by step. Corn is a late-maturing crop, and feeding new corn to chickens as soon as it is marketed can have a negative impact on performance. It is recommended that the new corn be dried for 1 month before feeding the chickens, and the new corn and old corn should be mixed, first replace one-third of the new corn, replace two-thirds after a period of use, and finally use all the new corn.

4. Corn should be purchased in moderation and not hoarded, so as not to reduce the quality and even mildew. Especially in the rainy season, while avoiding excessive purchase, we should also attach great importance to the storage of corn, and have a place that can shelter from the wind and rain, so as not to reduce the quality of corn due to improper storage.

5. If it is a small amount of free-range chickens, it is best to feed the chickens after the corn is broken, which will be conducive to the digestion and absorption of chickens and improve the utilization efficiency.

Soak 24 hours in advance to soften, put some sand and gravel in it 30 to 1

There is a type of crushed corn that can be fed directly.

Chicken mixed feed generally contains corn, soybean meal, fishmeal, etc., comprehensive nutrition, there is no need to mix corn, corn is commonly used to feed chickens, high metabolic energy content, but contains less manganese, only about 18 mg of manganese per kilogram of corn. If more than half of the chicken's diet is made up of corn, and the chicken does not pay attention to manganese supplementation, the chicken will develop "lameness" (slippery tendonosis) due to manganese deficiency. In particular, the broiler chicks raised in high beds or cages in the house are deficient in manganese in their diets, and there is an excess of calcium and phosphorus.

Some premixes can be mixed with corn in proportion for a more complete nutrition.

In the brooding and rearing stage, it is necessary to ensure the feed supply and supplement of chicks, rearing chickens and adult chickens according to the nutritional needs of chickens in the growth stage. Generally, before grazing, it is required to feed 5 times 6 times a day, and at the same time ensure sufficient clean drinking water. After entering the stocking period and having a strong free predation ability, artificial feeding can be gradually reduced to 2 times 3 times a day, and pay attention to feeding less in the morning and more in the evening.

Is the feed a full price feed or a premix? If it's full-priced, don't mix it with corn. If it is a premix, it should be matched according to the instructions of the premix.
