Utilization of beet meal

Sugarbeet residue is a by-product of sugar production. It is the residue of sugar beet root and tuber after soaking and pressing to extract sugar solution. Therefore, there are a lot of water-insoluble substances in the residue, especially crude fiber. It is a good juicy feed for livestock. It can also promote lactation for female livestock, and is mainly used for feeding cattle. The main ingredients are soluble nitrogen free substances, but there is little protein and fat. There is very much calcium and little phosphorus, which is palatable and contains more crude fiber.

1. The wet beet residue should not be fed too much and should be mixed with protein feed or other green feed, such as soybean cake, corn, wheat bran, hay, silage, carrots, etc. The recommended feeding amount should not exceed 10% of the ration: 1.50-3.50 kg/day · pig, 2.50-3.50 kg/day · sheep. Cows can be fed 12kg a day, and young bulls can be fed 24kg Beef cattle 30-40kg/day. Pigs shall be fermented and fed only to fattening pigs and lactating sows. For ruminants, wet meal can be fed directly. Dry cypress can replace about 30% of cereals in the diet. It can be mixed with concentrate after soaking or fed alone

In the whole concentrate H grain for fattening pigs, beet residue was used to replace 15% corn (LW=35~60kg) and 25% corn (LW=60~90kg), which did not affect the weight gain, reduced the cost, improved the carcass quality, and increased the lean meat percentage. The use of beet residue instead of cereal feed (barley) in the diet of Holstein cows in the late lactation period did not affect the milk yield of milk protein and lactose, increased the milk fat rate and energy level, and decreased the plasma glucose and cholesterol content. This is because beet residue contains high neutral detergent fiber pectin, niacin and betaine.

2. Silage of beet residue

The fattening pigs (LW=34~144kg) could not affect the growth and slaughter performance of pigs by replacing barley with silage beet residue added with liquor tank. Therefore, silage beet residue can be used to save grain feed.

In order to improve the quality of silage, the addition of absorbent (grain, corn stalk soil, polyacrylamide) can reduce nutrient loss. China is rich in crop straw, which is a good absorbent resource. Adding absorbent during silage can reduce the loss rate of soluble sugar, increase the content of dry matter, acid detergent fiber and crude protein, reduce the content of neutral detergent fiber, and effectively reduce butyric acid fermentation. Urea 4g/kg and 6g/kg (nitrogen content 46%) can also be added to reduce the pH value. Ammonia nitrogen, crude protein and soluble sugar content increased significantly, and butyric acid production was inhibited. 0.034% - 0.064% molasses silage can also be added, which can improve the feed conversion efficiency and dry matter intake of goats. The reason is that the beet residue has good palatability. After adding honey silage, the nutrient content is increased, and the dry matter content can reach 847g/kg Crude white matter is 115g/kg, and soluble sugar content can reach 270g/kg.

3. Mixed silage of sweet rice dregs

Adding crop by-products (rice straw, corn straw, bean pod and bran) can make the talent content reach 70%, improve the silage quality of beet residue, reduce ammonia nitrogen, and increase the content of dry matter, crude protein and soluble sugar. It is suggested that 10% - 20% crushed dry rice straw should be added to the beet residue silage. The second is dry bean pods, which crush thousands of corn stalks and bran. Mixed silage can make nutrients complementary and prolong the storage time.

4. Sugar beet residue granulated meal

After the granules are made, the moisture content is reduced, the transportation is convenient, and the preservation is beneficial. Sugarbeet dregs can further improve the utilization rate of nutrients, improve feed returns, eliminate anti nutritional factors, avoid animal pickiness, ensure the full price of feed and facilitate feeding through the effects of high temperature steam, pressure and other factors in the pelleting process The artificial feeding is reduced, and the feeding time is 1/3 of the powder, which reduces the consumption of feeding activities of high poultry and the natural loss of feed.

Beet meal was used to replace 15% - 40% (energy feed (corn) with wide dry matter basis) in the diet of dairy cows It can increase the feed conversion rate, milk fat rate and milk protein rate, reduce the risk of rumen acidosis, hoof disease and heat stress, buffer the rumen pH value, and improve the rumen function. These functions are derived from the rich soluble fiber and pectin in beet residue.

5. Other values of beet residue

The American Helette Aquaculture Research Institute also introduced the use of beet residue as a cheap shrimp bait. Sugarbeet residue can be used to prepare oxalic acid, cellulose and pectin. The beet residue also has the function of reducing blood lipid, and can be developed as a health product.

The yield of beet is huge, and the nutritional value of beet residue has been widely recognized by researchers. In addition to the pressure of grain shortage, beet residue has become a potential feed resource with development value.

6. The value of betaine

Beet meal is rich in betaine. As a methyl donor, betaine has similar nutritional effects with methionine and choline, and has the functions of improving the production performance of cows and sows, regulating lipid metabolism, etc.

By promoting the synthesis of phospholipids in the body, betaine, on the one hand, reduces the activity of fat synthase in the liver, on the other hand, promotes the synthesis of apolipoprotein in the liver, promotes the migration of fat in the liver, reduces the content of triglycerides in the liver, and effectively prevents the accumulation of fat in the liver. It can reduce the deposition of body fat by promoting the decomposition of fat and inhibiting the synthesis of fat. Betaine has a significant effect on reducing the liver fat content of grass carp. When grass carp are fed with formulated feed for a long time without green feed supplement, adding betaine can effectively prevent fatty liver disease caused by nutrient deficiency.
