Feed yeast for pigs is one of the most important additives in the diet of animals, allowing them to grow full-fledged pigs. Yeasting is necessary for a balanced diet for pigs. This product is widely used as a protein and vitamin supplement and for proper absorption of protein from grain mixtures. Ingredients: protein, protein, fat, dietary fiber, fiber. Pork production is a fairly efficient branch of animal husbandry, allowing you to obtain a product of proper quality in a relatively short time and with low financial costs. 1
What is “feeder yeast”
The best grains for yeast use are corn, oats, barley and bran. It is important to understand that the state of the pigs’ body, their immunity and subsequent productivity depend on a high-quality diet. This also affects the qualitative increase in muscle mass of animals.
It is recommended to thoroughly grind and mix the food before feeding. This will allow the food to be absorbed in the pig’s body by more than 90%.Today, yeast is one of the high-quality and simple ways to prepare feed.
The meaning of yeast is the proliferation of yeast and lactic acid bacteria, which significantly increase the taste and appetite level of pigs. As a result of fermentation, the pH increases (which prevents the development of pathogenic bacteria), feed mixtures are significantly enriched with vitamins B, D, K, E and enzymes.
Feeder yeast is a dry biological mass of yeast cells based on plant and non-plant raw materials, grown for the production of feed for farm animals. It is a highly valuable protein and vitamin product and is used as a dietary supplement. Feed grade yeast is produced from regular yeast. Their production is based on growing microorganisms in a special nutrient medium consisting mainly of monosaccharides.
To do this, the crushed raw materials undergo a hydrolysis process at a certain temperature and pressure. The acid is extracted from the resulting hydrolyzate, neutralizing it with milk of lime. Then it is cooled, settled, and mineral salts, vitamin supplements and other useful substances are added. The resulting mass is sent to the fermentation shop, where the yeast is grown. Next, the substance goes through a drying process in compliance with all the standards of this technology (GOST 20083-74). As a result, the yeast is a mixture of a light brown hue with a distinct odor.
Benefits of introducing feed yeast into the diet of pigs
It is known that when it is necessary to accelerate the development and growth of an animal, a sufficient amount of protein is needed, which is the main component in the formation of cells.But elements such as methionine, lysine and other amino acids cannot be synthesized by the pig’s body on its own; they must come from food.
In terms of the content of useful substances, yeast is similar to protein of animal origin, and in terms of energy content it is significantly superior to many plant feed additives. A lack of protein in a pig’s body leads to various diseases, especially in young animals. The use of yeast feed for pigs significantly increases the total body weight of the animal and increases the body's resistance to infections and viruses. In addition, it is a safe and cost-effective product.
Varieties of feed yeast
There are 3 main types of feed yeast, distinguished by the type of organisms used and the growing environment:
- classic feed yeast is grown using simple yeast fungi during the processing of waste from the alcohol industry;
- protein-vitamin mass is made using feed yeast on waste non-plant raw materials;
- hydrolysis feed yeast is obtained by cultivating fungi through the hydrolysis of wood and plant waste.
Each type has its own advantages and disadvantages. For example, BVK has an increased amount of protein (in dry form, about 60%), but only 40% protein. In its classic form, the amount of protein is about 50%, and the total concentration is 43%. Hydrolytic yeast contains a high percentage of riboflavin and folic acid. Thus, it is recommended to sometimes use different feeding methods. This will bring greater effect.
How to properly feed feed yeast to pigs
You can feed feed yeast in dry form by adding it to the feed. But about 30% of the diet should be subject to yeast.When the supplements are soaked, the yeast cells divide, increasing the volume of protein. This is called yeasting. Since ready-made concentrates are not sold, yeast is carried out independently. To do this, some of the grain mixture from the diet is mixed with yeast.
Feed yeast methods
There is a sponge and a straight method of yeast.
Sponge consists of several processes: preparing the dough and directly yeasting. The dough can be prepared as follows: 100 kg of dry food is mixed with 1 kg of yeast, 50 liters of warm water are added and, while stirring, the yeast is added. Next, 20 kg of feed is gradually poured in and the resulting mixture is thoroughly mixed every half hour. The preparation time for the dough is 5-6 hours.
Yeasting: add 150 liters of warm water to the resulting dough and mix this mass, add the remaining 80 kg of concentrated feed to the container. Then knead every hour until the end of ripening. The yeasting process will take 2-3 hours.
Safe method. In this case, yeasting begins immediately, without preparing the dough. For 100 kg of dry food, take about 0.5-1 kg of pressed yeast, which is first diluted in water. 150-200 liters of warm water and diluted yeast are poured into the container, and then 100 kg of feed is carefully poured. The resulting mass must be stirred every 20 minutes. Yeasting will last about 6-9 hours.
Feed is prepared in a separate clean room with good ventilation and a temperature of at least 20 degrees. In order for yeast to proceed according to all the rules, and for the food to be saturated with oxygen, it is necessary to stir the mass as often as possible. Yeasting is also affected by temperature, acidity and food quality. It is advisable to use foods rich in sugar, such as sugar beets.Molasses, boiled potatoes, sprouted barley and oats, and raw crushed carrots help the yeast process. Animal feed should be no more than 15%. Yeasting of pig feed can also be done at home.
Standards for piglets and pigs
Feeding rates directly depend on the category of the animal and its physiological state and allow you to normalize the individual needs of each animal. Therefore, the dosage of yeast for pigs is taken into account separately for each category.
Dosage for small piglets
Already in the first week of life, piglets lack mother's milk. During this period, feed additives begin to be introduced. In this case, it is necessary to observe the percentage ratio of feed and yeast. When feeding suckling piglets, the percentage of yeast in the total volume of feed should be no more than 3%.
For weanlings, the concentrate will be 3-6%. For piglets that have completely switched to self-feeding, yeast will be 7-10%. For piglets fattening with stillage, the powder dosage will be at least 10%. This will increase the animal's growth significantly.
It is recommended to introduce yeast feeding gradually. The first feeding should be about 10 g. In subsequent feedings, the volume is increased each time, and by 1.5 months 60 g of yeast should be given, and by 2 months up to 100 g. During the fattening period, the dosage increases to 200 g.
Norms for adults
Pigs need to be accustomed to yeast-based feeds correctly. You need to start with 10-15% and gradually increase to 40% of the fed norm. After a month of feeding, it is recommended to exclude the supplement for 10-15 days.When introducing yeast into the diet, it is necessary to ensure the cleanliness of the feeder and remove leftover food, otherwise there is a high risk of gastric diseases.
For sows during pregnancy, feed yeast will be especially useful. They are given to the pig every day, mixed with feed. The daily dose should be 10-20% of the powder per daily requirement. This supplement promotes healthy offspring.
For lactating sows the norm will be 3-12% of the total amount of food. The average dosage per pig should be 300 g. The additive should be administered immediately after farrowing, as it increases lactation by 1.5 times.
The daily norm of yeast for breeding boars is 300-600 g. It significantly enhances sexual activity and affects reproduction.
The dosage of feed yeast for pigs fattened for bacon is no more than 6% of the weight of the fed concentrates. This product is a good substitute for skim milk.
When raising pigs, the farmer must comply with certain standards for keeping, caring for and feeding animals:
- the holding room must be bright and clean, the humidity level is not lower than 70%, and the temperature is lower than +15 degrees;
- food should only be fresh, yesterday’s food will not give you the opportunity to quickly gain weight;
- It is better to start fattening in the warm season (spring-summer), since during this period there is more opportunity to feed pigs with plant foods;
- provide pigs with fresh water and free access to it;
- so that pigs do not gain excess fat, they need to be fed rationed;
- products of plant origin must be thoroughly crushed, since their body has difficulty digesting food;
- kitchen waste must be thoroughly boiled for an hour to avoid the proliferation of pathogenic microflora;
- feed needs to be salted, as salt helps stimulate digestion;
- Do not give hot food under any circumstances - it must be at an acceptable temperature;
- Pigs should be taught to eat at the same time several times a day;
- Throw away any food leftovers, wash the feeders immediately, and disinfect them twice a week.
It is imperative to include feed yeast in the diet, which can compensate for the lack of amino acids, vitamins and microelements.
Conclusion
Feed yeast for pigs is mandatory for use in agriculture, since today it is an inexpensive and effective way to significantly increase the productivity of animals both on large farms and at home. Their use does not lead to undesirable consequences, provided the dosage is calculated correctly. All products obtained from animals are absolutely safe for humans after using these feeds.
