Sugar beet pomace and its use in animal nutrition

؟What is sugar beet pulp

Sugar beet pomace is one of the by-products that has a higher energy value than silage corn due to its high amount of digestible fiber. Also, sugar beet pomace has high fiber, energy and calcium and can be used as a substitute for wood fodder in Livestock ration is used and affects the final price of the ration. When sugar and other extractable substances are taken from sugar beet along with water, sugar beet pulp is obtained. After being dried by special devices, the beet pomace is made in the form of wire, flakes, and molds, in which molasses is sometimes used in its production

The use of sugar beet pomace in feeding different herd groups should be determined by formulating the ration and taking into account the nutritional needs of different groups. Sugar beet can also be used to feed animals before processing or extracting sugar. Of course, it is better to cut the beets into smaller pieces using a chopper or grinder to prevent bloating or suffocation. In beet by-products that have high humidity due to the possibility of mold, the products must be well stored and used at the right time before mold

  Using beet pulp in winter is very useful due to the lack of pastures. This product is often available in the market in the form of pellets or fluff, which type of fluff can reduce the incidence of flatulence in livestock

؟How is sugar beet pulp obtained

:Removal and washing

Once the roots are harvested and cleaned and washed, they are cut into small pieces. When sugar is extracted from crushed sugar beet by diffusion method (hot water at 75 degrees Celsius), then wet pulp or fresh pulp is obtained, which has 90% moisture. When it passes through the first presses, it is converted into pressurized pulp (72% moisture)

The sludge is directed into the dewatering devices and dried in the rotary dryer. With the flow of hot air (600 to 800 °C at the entrance of the dryer), the humidity in these products is reduced to 12%.

؟What are the characteristics of spoilage of sugar beet pulp

Mildew and fungus on the scum that can be easily seen-

Bad smell or burning smell-

In a template. Its weight is between 2 and 5 kg-

Color: The color of dry beet pulp depends on whether molasses was used in its preparation or not, it is changing from light brown to dark brown

Nutritional benefits of sugar beet pomace

The energy obtained from the fermentation of beet pomace in the rumen is high. This product is similar to barley in terms of energy, but in terms of protein, it is at an average or low level

Digestible fibers of sugar beet pomace such as cellulose are good features for ruminants. These fibers provide stability in the rumen environment

When dry beet pomace is used for horses. It is better to be soaked

Although the amount of starch and phosphorus of this product is low, but the amount of sugar is high

One of the characteristics of dry beet pomace is the good absorption of liquids, because during the production of silage, part of its nutrients are removed from it in liquid form. By adding beet pulp, its waste can be prevented

Sugar beet pomace is considered a very good prebiotic for animals, meaning it can benefit the millions of microbes in the gut. A strong, well-functioning microbiome contributes to the overall health of the body. Despite other prebiotic benefits, this pulp should never be the only source of fiber in an animal’s diet, and the protein content of this product is moderate

Consumption restrictions and anti-nutritional factors of beet pomace

Beet pomace is slightly laxative. The bulkiness of this product and its fibrous nature make its consumption unsuitable for monogastrics, including poultry. There are no restrictions on the use of beet pomace in sheep and cattle. According to the results of some researches, consumption of more than 50% in the ration can reduce appetite in animals. Factors such as bulkiness and high humidity of this product can also limit its use in sheep. If you want to use wet beet pomace, transportation is also considered as one of the limiting factors

Consumption of sugar beet for animal feed

Sugar beet pomace is used in animal feed in two forms, dry and wet

Dry sugar beet pomace

Experiments have shown that the use of grain rations such as bran, soy, corn along with beet pomace have more nutritional value compared to grain rations

Dry manure should never be used as the sole hydrocarbon ingredient in animal feed. Because in this state, the slag cannot show its properties. In addition to better absorption, consumption of beet pulp mixed with granular materials will also prevent abdominal bloating. According to the results of the tests; Using it in this way will also be useful and effective in increasing milk. One of the most important reasons why beet pomace is valuable for animal husbandry should be noted that the use of pomace along with grain feeds causes more food consumption in livestock and makes livestock gain weight faster

Sugar beet pulp

Watery beet pulp is stored in large, shallow pits. These pits should be carpeted and have enclosed walls. In these pits, an acid fermentation takes place on the juicy scum and then it is consumed at appropriate intervals before the scum rots. Ensiled pulp has a longer shelf life than non-ensilated pulp

؟What animals can sugar beet pulp be used for

This scum can be used in the diet of fattening lambs-

This waste can be added to the diet of animals such as cows and fattening calves-

This scum is also suitable for the diet of lactating animals-

Use of sugar beet pomace in sheep feed

Sheep that use beet pomace in the form of pellets and dry, will be more prone to bloat and suffocation. To reduce the possibility of these risks, wastes should not be used before they are fully soaked and opened. To soak the scum, twice the weight of the scum is added to them. Soaking lasts for 30 minutes if hot water is used and 1 hour if cold water is used. After the end of soaking, the scum softens and its volume doubles. Before consuming the soaked wastes, their excess water must be drained. Wet beet pulp should be stored in silo bags, pits or ponds. Adding beet pomace to livestock feed should be done gradually. Usually, sheep can be fed 1 to 4.5 kg of dung per day

Another sugar beet by-product is beet residue, which consists of small, broken or damaged beets. These wastes often have a moisture content of about 80%, which can be different in terms of content and nutritional value. If the level of pollution of these products to the soil is less, the amount of their consumption can be used more than the amount of silated corn in the rations. In case of beet waste contamination, its use in animal feed should be minimized. Beet residue can be stored as silage like other beet by-products. It is noteworthy that these materials must be ensiled together with dry food due to high humidity

Sugar beet processing often continues from early autumn to late spring, and the resulting products are stored dry in warehouses or in the form of beet silage in the summer season
