Dosage of feed yeast for pigs
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 the feed for pigs.

Why pigs can 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 take 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 blood to the organs.
- Sexual dysfunction in males, as well as a violation of the reproductive cycle in females. All this indicates the inability of individuals to normal reproduction, 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 bone 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 is that yeast colonies are placed in a nutrient medium, where they actively multiply. After the feed yeast is dried, and 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 from the alcohol industry.
- Protein-vitamin concentrate, which is synthesized with the help of non-plant products from petroleum products, ethanol, methanol and paraffins.
Acetic acid and monosaccharides are used in the production. These substances are found in abundance in vegetable and fruit waste. Although the process is complex from a technical point of view, the products come out much cheaper than the production of compound feed. The use of waste as raw material 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 diet 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 its end, the mass is dried, thereby resulting in a powdery substance of dark brown color.
When fattening animals, the dosage of fodder yeast should be at least 10% of the total amount of fodder. 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 replenish the strength of the farrowed pig.
You can also give feed yeast to piglets. The introduction of the dietary 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. For weaned pigs, the dose is doubled. Although protein is important for the growth of young stock, there is a possibility of digestive problems due to its overabundance. Farmers' opinions on whether piglets can be fed yeast differ greatly for this very reason.
How to feed pigs with feed yeast
Correctly selected feed and its dosage is only half the battle. It is also necessary to properly prepare 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. To do this, take 10 liters of boiled warm water, into which 150-250 g of feed yeast and about 4 kg of concentrates are immersed. After the mass is mixed until smooth, it is left for 5-6 hours in a warm room. While the mixture is fermenting, 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 the 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.
