Feed yeast for pigs is one of the most important additives in the diet of animals, allowing you to grow full-fledged individuals. Yeast is essential for a balanced diet in pigs. This product is widely used as a protein and vitamin supplement and for the proper assimilation of protein from grain mixtures. The composition includes: protein, protein, fat, dietary fiber, fiber. Pork production is a fairly efficient branch of animal husbandry, which makes it possible to obtain a product of good quality in a relatively short time and at low financial costs. one
What is “feed yeast”
The following grains are best suited for yeasting: corn, oats, barley and bran. It is important to understand that the state of the body of pigs, their immunity and subsequent productivity depend on a quality diet. It also affects the qualitative increase in the muscle mass of animals.
It is recommended to thoroughly grind and mix the feed before feeding. This will allow the food to be absorbed in the body of the pig by more than 90%. To date, yeast is one of the high-quality and simple ways to prepare feed.
The meaning of yeast lies in the reproduction of yeast and lactic acid bacteria, which significantly increase the taste and appetite of pigs. As a result of fermentation, pH rises (which prevents the development of pathogenic bacteria), feed mixtures are significantly enriched with vitamins B, D, K, E and enzymes.
Feed yeast is a dry biological mass of yeast cells based on vegetable and non-vegetable raw materials, grown for the manufacture of feed for farm animals. It is a highly valuable protein-vitamin product and is used as a bioadditive in the feed ration. Feed yeast is produced from conventional yeast. Their production is based on the cultivation of microorganisms in a special nutrient medium, consisting mainly of monosaccharides.
For this, the crushed raw materials undergo a hydrolysis process at a certain temperature and pressure. Acid is extracted from the resulting hydrolyzate by neutralizing it with milk of lime. Then they cool, defend, add mineral salts, vitamin supplements and other useful substances. The resulting mass is sent to the fermenter shop, where the yeast is grown. Then the substance goes through the drying process in compliance with all the norms of this technology (GOST 20083-74). As a result, the yeast is a mixture of a light brown hue with a pronounced odor.
Benefits of introducing fodder 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. And elements such as methionine, lysine and other amino acids cannot be synthesized by the pig’s body on its own, they must be ingested with food.
In terms of the content of nutrients, yeast is similar to protein of animal origin, and in terms of energy content, it is significantly superior to many vegetable feed additives. The lack of protein in the body of a pig leads to various diseases, especially in young animals. The use of yeast feed for pigs significantly increases the total body weight of the animal, increases the body’s resistance to infections and viruses. In addition, it is a safe and cost-effective product.
Varieties of fodder yeast
There are 3 main types of fodder yeast, distinguished by the type of organisms used and the growing medium:
- classic fodder yeast is grown using simple yeast fungi, during the processing of waste from the alcohol industry;
- protein-vitamin mass is made using fodder yeast on waste non-vegetable raw materials;
- hydrolytic fodder yeast obtained during the cultivation of 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 (about 60% in dry form), but only 40% of protein. In the classical form, the amount of protein is about 50%, and the total concentration is 43%. Hydrolysis yeast contains a high percentage of riboflavin and folic acid. Thus, it is sometimes recommended to use different feeding methods. This will bring more effect.
How to feed feed yeast to pigs
You can feed dry fodder yeast by sprinkling it into the feed. But about 30% of the diet should be yeast. When supplements are soaked, the yeast cells divide, increasing the amount of protein in the process. This is called yeast. Since ready-made concentrates are not sold, yeast is carried out independently. For this, some part of the grain mixture from the diet is mixed with yeast.
Feed yeasting methods
There is a paired and non-paired method of yeast.
Sponge consists of several processes: preparation of sponge and yeast directly. Opara 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 the yeast is added while stirring. Then 20 kg of feed is gradually poured in and the resulting mixture is thoroughly mixed every half hour. Cooking time for sourdough is 5-6 hours.
Yeast: add 150 l 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 maturation. The yeasting process will take 2-3 hours.
Safe method. In this case, the yeast starts immediately, without preparing the dough. About 100-0,5 kg of pressed yeast is taken per 1 kg of dry food, it is first diluted in water. 150-200 liters of warm water, diluted yeast are poured into the container, and then 100 kg of feed are carefully poured. The resulting mass must be mixed every 20 minutes. Yeast will last about 6-9 hours.
Food is prepared in a separate clean room with good ventilation and a temperature of at least 20 degrees. In order for the yeast to pass according to all the rules, and 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. Helps the process of yeast molasses, boiled potatoes, germinated barley and oats, raw crushed carrots. Animal feed should be no more than 15%. Yeast feed for pigs can be carried out at home.
Norms for piglets and pigs
Feeding norms directly depend on the category of the animal and on its physiological state and allow 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 do not have enough 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 amount of compound feed should be no more than 3%.
For weaners, the concentrate will be 3-6%. Pigs that have completely switched to self-feeding, yeast will be 7-10%. For piglets fattening stillage, the dosage of the powder will be at least 10%. This will increase the growth of the animal to a great extent.
It is recommended to introduce top dressing with yeast gradually. The first time 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
It is necessary to accustom pigs to yeast feed 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. At the time of introducing yeast into the diet, it is necessary to monitor the cleanliness of the feeder and remove food debris, otherwise there is a high risk of gastric diseases.
For sows during gestation, fodder yeast will be especially beneficial. They are given to the pig every day, mixed with feed. The daily dose should be 10-20% of the powder per daily allowance. 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 supplement should be administered immediately after farrowing, as it increases lactation by 1,5 times.
The daily rate of yeast for breeding boars is 300-600 g. It significantly enhances sexual activity and affects reproduction.
The dosage of fodder yeast for pigs fed for bacon is not more than 6% by weight of the fed concentrates. This product is a good replacement.
When raising pigs, the farmer must comply with certain standards for keeping, caring for and feeding animals:
- the room for keeping should be bright and clean, the humidity level should not be lower than 70%, and the temperature should be lower than +15 degrees;
- food should be only fresh, yesterday’s food will not allow you to quickly gain weight;
- it is better to start fattening in the warm season (spring-summer), since during this period it is more possible to feed pigs with plant foods;
- provide pigs with fresh water and free access to it;
- so that pigs do not gain an extra fat layer, they need to be fed rationed;
- products of plant origin must be carefully crushed, since their body is difficult to digest food;
- waste from the kitchen must be thoroughly boiled for an hour to avoid the reproduction of pathogenic microflora;
- feed needs to be salted, as salt helps to stimulate digestion;
- in no case do not give hot food – it must be at an acceptable temperature;
- pigs should be taught to eat at the same time several times a day;
- Throw away food residues, and wash the feeders immediately, disinfect twice a week.
It is necessary to include fodder yeast in the diet, which can compensate for the lack of amino acids, vitamins and trace elements.
Conclusion
Feed yeast for pigs is mandatory for use in agriculture, as today it is an inexpensive and effective way to significantly increase the productivity of animals both on large farms and in the backyard. Their use does not lead to undesirable consequences, provided that the dosage is correctly calculated. All products obtained from animals, after the use of these feeds, are absolutely safe for humans.
