Using feed yeast for pigs can significantly increase the weight gain of muscle mass, in the shortest possible time growing healthy and well-fed pets. One of the most productive methods of fattening is considered to be the yeast of food concentrates included in the diet of livestock. The method provides fattening piglets, sows and boars-producers with the necessary amount of easily digestible proteins, vitamins and trace elements, increasing the productivity of the pig-breeding complex.
Healthy Yeast Mushrooms
Yeast, by its nature, is a single-celled fungus that thrives in a liquid or semi-liquid medium rich in carbohydrates and other organic substances. By processing sugars, yeasts grow and multiply very quickly, accumulating proteins in their bodies that are well absorbed by the human body and animals.
They are used in the fattening of almost all farm animals grown for meat, and in industrial pig breeding are particularly important. Fodder yeast gives the food concentrates a certain taste, greatly increasing the appetite of pigs, and the protein contained in their cells is absorbed by animals by 95%.
In addition, feeding yeast allows you to speed up the process of assimilation of amino acids and the synthesis of protein mass, as well as saturate the body of a pig with sulfur, phosphorus and calcium, necessary for the development of bones and articular tissues. Fat metabolism regulates vitamins of group B contained in this fungal culture. Vitamin H (biotin) ensures the production of red blood cells, protecting piglets from anemia, dry skin and seborrheic dermatitis.
Almost completely digestible protein
If you are feeding piglets using traditional vegetable feed, you will definitely encounter the problem of not gaining enough muscle mass. This is due to the fact that even in cereal mixtures, the amount of protein rarely reaches a figure of 30%, and he himself cannot fully digest himself by the body.
A lack of protein can lead to various problems that are most pronounced in dairy pigs, often suffering from anemia, as well as reproductive pigs that lose their ability to grow viable offspring.
The addition of yeast to pigs' feeds allows these problems to be successfully solved by significantly increasing the rate at which they are gaining live weight. Depending on the type of yeast substance, the amount of proteins in it can be 32-38% of the total mass, and the amount of almost completely digestible amino acids can reach 51% of the dry mass.
Improve health and reproductive capacity
When the content of pregnant sows daily dosage in 7-10% of the yeast of the total amount of feed allows you to get a guaranteed income in the form of one additional pig for offspring (with an average farrowing of 11-12 animals).
If yeast feeds are given to suckling sows, the amount of milk they produce increases by 10-15%, allowing the kids to be provided with the right amount of food without having to buy an expensive substitute of whole milk replacer.
Starting at ten days of age, the piglets can add yeast concentrates to the feed, gradually bringing the amount of fungus from 3 to 10% of the total dry food. Depending on the breed of pigs, the daily increase in their muscle mass will increase by 8-17%, significantly increasing the profitability of production.
A large boar manufacturer is recommended to give up to 400 g of fodder yeast daily during the entire period of mating. Some farmers increase this amount to 600 grams per day, focusing on the age and weight of the animal. This helps stimulate the production of seed production and increases the likelihood of the appearance of stronger offspring.
It is better to breed yeast fungus alone
Some novice pig producers simply add acquired fodder yeast to food concentrates and feed them to animals. But this is wrong, since it requires the purchase of large quantities of this dietary supplement, and the cost of pork increases significantly.
The most productive way to use this product is yeast feed concentrates. It can be carried out using various technologies. The farmer himself selects the method that he considers most practical and beneficial.
Experts in the field of pig breeding recommend conducting sponge, seedless and starter yeast feed. Each of these methods has its advantages and disadvantages. They depend on the size of the pig-breeding complex, the availability of special premises for yeast, as well as the number of utility workers who will be responsible for the preparation of feed concentrates.
Therefore, be sure to calculate the possible costs before choosing which of the methods of yeast is preferable for you.
Sponge yeast feed method
To prepare the brew, you need to take 10 liters of water, pre-boiled and cooled to 25-30 degrees Celsius. It is necessary to dissolve from 150 to 250 g of fodder yeast, carefully stretching the lumps that appear. Under conditions of a small yard, a sieve can be used through which the yeast mixture should be passed.
4 kg of concentrates are added that you use to fatten your pets. After thorough mixing the container should be set aside for 6 hours in a warm place. Every 30-40 minutes, stirring is repeated, trying to saturate the composition with oxygen, activating the development of yeast fungi.
After 6 hours, add about 30 liters of warm water to the fermented mixture (boiling is not necessary) and 15 kg of feed.
The mixture is kept warm and allowed to wander for another 3-4 hours, after which it can be fed to pigs using the recommended feeding norms for these animals. Below we will talk about them, and for more information on the number of products, read the article "How much feed you need to raise a pig."
Straight Yeast Method
A simpler method of yeast is fermentation of the concentrate without pre-cooking the sourdough. In this case, you need to take immediately the entire volume of feed in an amount of 20 kg. He poured 10 liters of pre-boiled warm water, which was previously dissolved 150-250 g of yeast. After thorough mixing, the mixture is transferred to a large container, where you should add another 35 liters of warm water.
The fermentation process is carried out in a separate well-ventilated area and lasts about 9 hours. Regular mixing will allow you to saturate the mixture with air, and good ventilation eliminates unpleasant odors and prevents the fungus from spreading to the walls.
This method is less labor-intensive than the preparation of brew, but the amount of yeast fungus in the finished feed will be slightly lower due to the decrease in the rate of its reproduction.
Use leaven to save time and money
When growing a large number of piglets, it is advisable to use the yeast starter yeast feed method. It is the least costly, it allows the pig breeder to be freed from doing extra work, as well as from the need to constantly acquire fodder yeast.
This method uses the principle of self-production of yeast fungus, which grows rapidly in a nutrient medium.
For the preparation of the starter, you need to take about 45-50 liters of warm water, in which you need to dissolve up to 250 g of fodder yeast. The resulting solution is thoroughly mixed with 20 kg of feed concentrate, after which the tank is installed in a special fermenting room in which it will remain until the completion of the animal fattening process.
After 5-7 hours, fermented feed can be given to pigs. Half the starter material is taken from the tank, and the same amount of water and concentrate is added instead. The ripening process continues continuously, and the breeder only needs to add the missing ingredients in a timely manner (without the yeast itself) and mix the mixture at least 3-4 times a day.
The past yeast feed will stimulate the process of digestion and increase in muscle mass in animals, but it should not be more than 35-40% of the daily diet of the pig.
Calculation of feed standards for the age and purpose of pigs
When keeping pigs, experts do not recommend overfeeding them with yeast fungus, as this may lead to a deterioration in the general condition of the animals. The average consumption rates of fodder yeast per pig are:
- for pig-suckers no more than 1-3% of the total amount of dry feeding of finely ground or 10-15 g per day;
- weaned piglet eats 80-100 g of yeast per day or 2-6% of the total amount of feed;
- fattening youngsters from 3 to 10% (up to 200 g);
- pregnant sows require 250-300 g of yeast per day or from 7 to 21% of the total amount of concentrates consumed;
- lactating piglets sows receive up to 300 g of fodder yeast per day, while their total milk production increases from 56.9 to 70.5 kg;
- boar-maker should eat 300-400 g of yeast per day, and during the period of mating, this number is increased to 600 g
When bacon fattening, piglets are not recommended to add more than 6% of feed yeast to food, although at home the rate of 10% of yeast fungus of the total amount of dry feed concentrate is considered acceptable.
Benefits of using fodder yeast
The great advantage of yeast feed is that a pig or an adult pig gets the necessary amount of vitamins and microelements that contribute to the formation of a strong skeletal structure and a rapid increase in muscle mass. Piglets grow faster, which has long been noticed by specialists of large pig-breeding complexes, massively using fodder yeast for fattening pigs.
It is estimated that adding 1 kg of yeast to the feeders increases the average daily weight gain of piglets by 0.7-0.8 kg. At the same time, the savings of other feeds can reach 10% per kilogram of the obtained weight gain.
Consumption of fermented food eliminates sexual dysfunctions in males and disorders of the sexual cycle in females, many of which would have to be rejected during normal feeding. The number of babies in the farrowing increases, and the period of gestation proceeds without any particular complications.
Feeding with yeast allows you to get more viable offspring, reducing the mortality rate among babies to a minimum, and the abundance of milk in sows eliminates the need to spend money on the purchase of a substitute.
The disadvantages of the yeast fattening method
The only known disadvantage of the use of fodder yeast is the complexity of the preparation of fodder mixtures, the concentration of which must exactly meet the recommended standards.
For the yeast process, a separate room should be allocated, in which the optimum temperature of 20-25 degrees should be maintained and a good ventilation system should be equipped. To prevent the spread of the fungus outside the containers with feed, in yeast it is necessary to carry out regular cleaning and repair, in which the walls must be whitened with lime mortar. All this incurs additional costs.
Also a disadvantage is the need to use additional labor or special mechanisms by which the yeast mixtures are mixed.
In principle, every livestock breeder has the right to independently determine which method of fattening pigs is preferable for him, however, the obvious advantages of yeast make him increasingly common in Russia. Moreover, the use of such an additive is absolutely safe for humans.
