Feed yeast for pigs is one of the most important nutritional supplements in their diet. For good body weight gain, animals require a huge amount of protein, which cannot always be obtained from food in full. It is for the enrichment of the diet with proteins, as well as vitamins and microelements, feed yeast is added to pig feed.

Why pigs benefit from feed yeast
Lack of protein in feed provokes not only a decrease in pig productivity up to 30-38%, but also negatively affects the health of sows and young animals. If the mammalian body does not get enough vital amino acids, the cells have nowhere to get the building material for dividing and building muscle mass.
With a lack of at least one amino acid in the feed, the rest are absorbed worse. As a result, the pig begins to have problems with metabolism and assimilation of food. In advanced cases, a lack of protein leads to:
- Anemia - a low hemoglobin content in the blood. Its deficiency leads to oxygen starvation of all organs and systems of the body, since iron, which is an integral part of hemoglobin, cannot cope with the transfer of oxygen by the blood to the organs.
- Sexual dysfunction in males, as well as violation of the reproductive cycle in females. All this speaks of the inability of individuals to reproduce normally, which threatens material losses for farms specializing in breeding pigs.
- A decrease in milk production in sows, which is a consequence of insufficient nutrition and leads to the death of offspring. Piglets grow up painful or do not survive at all.
As a result, it can be seen that feed yeast for pigs plays an important role in the diet. They contain:
- sulfur, which is responsible for the synthesis of amino acids in the body;
- phosphorus and calcium, which are responsible for strong bone structure and skeletal growth in young animals;
- vitamins B1, B6, B12, which in turn regulate metabolic processes involving fats;
- biotin, a substance used to prevent diathesis and skin irritation.
If you use feed yeast in the right proportions, you can increase the productivity of the livestock by more than 45% (that is, almost 2 times). In comparison with the nutritional value of corn and wheat, the yeast supplement has a caloric content of 3.5-4 times higher.
What feed yeast is made from for pigs
Farm pig feed yeast is produced from commercial grade yeast. The production technology consists in placing yeast colonies in a nutrient medium, where they actively multiply. After the feed yeast is dried, the output is a light brown powder with a characteristic odor.
Depending on what raw materials are used for the manufacture of a food additive, the following types are distinguished:
- Hydrolysis, which are produced on the basis of dry household waste or wood residue.
- Classic, which are made from waste of the alcohol industry.
- Protein-vitamin concentrate, which is synthesized using non-plant products from petroleum products, ethanol, methanol and paraffins.
The production uses acetic acid and monosaccharides. These substances are found in abundance in vegetable and fruit waste. Although the process is complex from a technical point of view, the products are much cheaper than the production of compound feed. The use of waste as raw materials significantly reduces the cost of production. It is for this reason that yeast is so popular in livestock feed.

Dosage of feed yeast for pigs
During the introduction of yeast into the ration of pigs, it is necessary to carefully monitor the cleanliness of the feeders and remove uneaten food from them in time. Otherwise, there is a great risk of developing diseases of the gastrointestinal tract, as well as poisoning.
Yeast is not given to animals in its pure form. They are mixed with other food and create favorable conditions for the reproduction of the colony. This process is called yeast. At the end of the process, the mass is dried, thereby resulting in a dark brown powdery substance.
When fattening animals, the dosage of feed yeast should be at least 10% of the total amount of feed. This amounts to about 0.3-0.4 kg per individual. Pregnant females need a more nutritious diet, because for the normal formation of fruits, a sufficient amount of proteins, fats and carbohydrates is needed. They need to be given up to 0.5 kg of supplements per day. Lactating females are fed with yeast on the first day after giving birth. This increases lactation and helps to restore the strength of the farrowed pig.
You can also give feed yeast to piglets. The introduction of the food supplement should be done gradually to avoid digestive upsets and allergic reactions. Piglets should be given 0.1-0.15 kg of yeast per day, then the dose is increased every 3-4 days. To weaned pigs, the dose is doubled. Although protein is important for the growth of young animals, there is a possibility of digestive problems due to its excess. Farmers' opinions on whether piglets can be fed with yeast differ greatly for this very reason.
How to feed pigs with feed yeast
Correctly selected feed and dosage is only half the battle. It is also necessary to properly prepare the feed yeast for consumption.
When the additive is soaked, the yeast cells divide, thereby increasing the amount of protein they contain. This is feed yeast, which is actively used in many farms.
There are several ways in which yeast can be produced:
- Dough. For this, 10 liters of boiled warm water are taken, into which 150-250 g of feed yeast and about 4 kg of concentrates are immersed. After the mass has been mixed until smooth, it is left for 5-6 hours in a warm room. While the mixture ferments, it is stirred every 30-50 minutes for better aeration of the feed. After that, another 15 kg of concentrates and at least 30 liters of heated water are added. The mixture is left to ferment again for 3 hours, stirring occasionally.
- Without dough. In this case, the entire volume of compound feed (20 kg) and 10 liters of warm water with yeast diluted in it is taken at once. Next, the mass is poured into a large container and 35 liters of liquid are added. The yeast lasts about 7-9 hours.
- Leaven. This method is the most economical if we take into account the use of compound feed. No more than 35-40% of the total feed is used. The compound feed is poured with warm water and mixed until homogeneous. A solution is added to the feed and left to ferment for 5-7 hours. In order to give the leaven the opportunity to be saturated with oxygen, it is intensively stirred 3-4 times a day. In subsequent times after, before feeding, leave a small part.
Quality feed not only improves the metabolism in the pig's body, but also ensures optimal daily body weight gain. Also, the health of young animals and breeding individuals depends on the presence of proteins, fats and carbohydrates in the diet.
Conclusion
A product such as feed yeast has been used effectively by farmers for many years. This food additive can not only increase weight gain in fattening pigs, but also significantly reduce the costs of the farm itself.
You need to know exactly how much yeast is recommended for a particular pig. An excess of them in the body can cause the opposite result, as well as metabolic disorders.
