Can sows eat sake lees and is it good to feed pigs on sake lees?

Hello! Distiller's grains can be fed to sows, but do not feed them separately, because the distiller's grains are too simple in nutrients, so you should feed them with corn feed, tapioca flour or rice bran.

Distiller's grains are a by-product of the brewing industry, and the raw materials used are often diverse, such as rice, glutinous rice and sweet potatoes in the south, sorghum, corn, sweet potatoes and potatoes in the north, and barley in beer. The nutritional value of sake lees also varies depending on the type of raw material. In terms of nutritional value, good grain distiller's grains and barley beer's grains are about 2 times more nutritious than potato distiller's grains.

The liquor lees brewed with grain are mostly solid distiller's grains, with a moisture content of about 70%, characterized by a low nitrogen-free extract content, which is due to the fact that most of the starch has been turned into wine to be extracted, because of this, the crude protein content in the air-dried matter is relatively increased, which can reach about 20% 25%, but the protein quality is not good. In addition, distiller's grains are rich in phosphorus and B vitamins, as well as unknown growth factors, high content of methionine and cystine, and obviously insufficient lysine and tryptophan. In order to improve the wine yield, 20% and 25% rice husks should be added in the winemaking process, so that the crude fiber content in this kind of distiller's grains reaches more than 20%, which has a great impact on the digestibility of pigs.

In recent years, the complete set of distiller's grains feed processing equipment developed by Gansu Provincial Forage and Feed Research Institute can reduce the moisture content of fresh distiller's grains to less than 12%, and can separate the rice husks, so that the crude fiber has been reduced to less than 12%, which greatly improves the utilization value of distiller's grains.

Fresh brewer's grains have large moisture, good taste, aromatic flavor containing barley malt, rich in nutrients and yeast, lactic acid bacteria, high digestion and utilization rate, hygienic and safe, containing barley maltine, suitable for feeding pigs. However, due to the low energy content, the dosage of growing and fattening pigs is generally not more than 5%, and the gestation sows can be used to 20%, but it is not suitable to feed piglets. The nutritional content of sake lees is shown in Table 8.

Table 8 Conventional nutrient composition of several types of distiller's grains (%)

Untreated distiller's grains can be used to feed growing and finishing pigs, but not piglets, breeding sows and breeding boars. When used directly to feed fattening pigs, it is best to store them for one month to avoid ethanol poisoning due to the incomplete volatilization of ethanol. Distiller's grains are "fire-based" feeds, and too much can cause constipation or alcohol poisoning.

Therefore, the dosage of growing and fattening pigs is generally not more than 20% of fresh distiller's grains, and it is advisable to halve the dry distiller's grains, and it is best to feed more green and juicy feed at the same time.

If the lees are not stored properly, even dry sake lees are prone to rancidity and poisoning by the production of free acids (acetic acid, lactic acid, butyric acid) and fusel alcohols (n-propanol, isobutanol, isoamyl alcohol). The best way to preserve distiller's grains is to mix a certain amount of dry bran with a certain amount of dry bran for cellaring according to the moisture content, which is similar to silage; One is to take sedimentary preservation, that is, to pour the distiller's lees soup with more moisture into the cement pool to let it settle, and then suck out the water in the upper layer and then add new lees, so many times, and finally the sediment is a thick paste, which can be fed to pigs for a long time. But for the last time, be sure to retain a certain amount of stagnant water to isolate the air and prevent deterioration.

Piglets under 25 kg are not recommended to be fed sake lees. Medium pigs and large pigs should not be fed too much.

Piglets over 25 kg can not be fed too much corn distiller's grains, take fresh beer's grains to feed pigs, the feeding ratio should be controlled at less than 5% of the pig's diet, and the proportion of dry beer's grains should be less than 15% of the diet. Corn distiller's grains should be fed to pigs should be divided into large pigs and small pigs, the former should not be fed more than 15 percent, and the latter should not be fed more than 10 percent.

At first, it may be a little uncomfortable to feed the pigs with sake lees, some pigs will be picky eaters, and the pigs will get used to it after 3 to 5 days of smooth feeding period. When feeding distiller's grains, it should be increased gradually from less to more, and after the pigs are used to eating, they began to add feeding according to the amount of 10%, and they can be added to about 50% in the later stage, but they must be nutritionally balanced to achieve 50% of the amount of feeding.

Suggested feeding ratio: 40 kg piglets, you can first try to feed with 10% fermented distiller's grains feed, observe its more adaptable, you can slowly increase the dosage as follows, the proportion is 20%, 20 to 60 kg pigs: fermented distiller's grains feed from 20% to start feeding, slowly increase, the proportion of 40%.

Pigs over 60 kg: Fermented distiller's grains feed starts from 20%, the proportion is 60%, pregnant pigs are fed no more than 15%, and empty sows are fed 40% to 50%.

In the usual feeding process, add some green fodder and green vegetable leaves to improve nutritional comprehensiveness and meet the various nutritional needs of animal growth. The fermented distiller's grains are suitable for all stages of growth of fattening pigs, piglets, sows and other pigs.

Can piglets be worthy of eating sake lees, piglets can eat sake lees, which is very nutritious, and pigs grow faster.

You can eat sake lees, which is very nutritious.

Distiller's grains should be combined with other feeds, and should not be fed with single distiller's grains to feed pigs, which must be matched with a certain proportion of corn, bran, oil cake and other concentrate feed, and an appropriate amount of bone meal should be supplemented.

Yes, but not individually.

The nitrogen-free extract content in the vat is relatively small, so the quality of crude protein is much lower than that of normal feed. It is also lacking in various nutrients such as carotene, vitamin D and calcium-molarin. Therefore, when we use the wine trough to feed, we should properly match corn, soybean cake and other feeds.

Supplement an appropriate amount of calcium to increase the proportion of green feed. Increase the growth nutrition of pigs and avoid constipation and other undesirable phenomena.

Distiller's grains should be fed to pigs before high temperature treatment or drying, fresh distiller's lees should be added to about 50g of lime powder or baking soda powder per kilogram of distiller's lees, and stirred and mixed evenly. The amount of fresh wet distiller's grains to pigs should not exceed 20% of the diet, and the amount of dry distiller's grains should not exceed 8% of the diet. If the distiller's grains contain a large amount of blind spring slippery rice husk, the feeding amount should be reduced by 1 3 1 2.

Hello, yes, but not alone. The nitrogen-free extract content in the vat is relatively small, so the quality of crude protein is far inferior to that of normal sedan feed. It is also lacking in various nutrients such as carotene, vitamin D and calcium.

Therefore, when we use the wine trough to feed, we should properly match corn, beans, tung locust cakes and other feeds. Supplement an appropriate amount of calcium to increase the proportion of green feed. Increase the growth nutrition of pigs and avoid constipation and other undesirable phenomena.

Distiller's grains should be fed to pigs before high temperature treatment or drying, fresh distiller's lees should be added to about 50g of lime powder or baking soda per kilogram of distiller's grains, and stirred evenly. The amount of fresh wet distiller's grains to pigs should not exceed 20% of the diet, and the amount of dry distiller's grains should not exceed 8% of the diet. If the distiller's grains contain a large amount of rice husks, the feed amount should be reduced by 1 3 1 2.

Hope it helps, thank you,

Hello, I have seen your question and am sorting out the answer, please wait a while

How long to wait? In addition to being rich in nutrients, distiller's grains also contain some toxic and harmful components, which will have a certain impact on the health of pigs. First of all, there will be a certain amount of alcohol and fusel in distiller's grains, and pigs are prone to miscarriage or poisoning after feeding; Secondly, the total acidity of distiller's grains is relatively large, pigs are prone to acidosis after feeding, and sows are prone to premature birth or abortion; Finally, the crude fiber content in distiller's grains is less, and a small amount of feeding can promote the appetite of pigs, but too much feeding will affect the digestion and absorption of pigs, which is not conducive to the growth of pigs.

In general, sows during gestation are not suitable for distiller's grains, while other pigs can be fed distiller's grains in moderation, but it is important to prevent poisoning and other problems.

Gestation sows cannot be fed, other sows can be fed with feed.
