A pig develops normally if it eats a proper and balanced diet. The animal's diet should be mixed - natural food is combined with various nutritional supplements. They contain a high concentration of minerals, vitamins, and nutrients. Feeder yeast for domestic pigs acts as a source of protein, fat, proteins, dietary fiber and fiber. The product is used to accelerate the growth rate of pigs and improve their health.
What is feed yeast?
Nutritional yeast is a separate type of fungus.Each manufacturer uses its own technology for cultivating them, but the usual technical type of yeast is predominantly used.
A nutrient medium is prepared for the mushrooms, which promotes their rapid reproduction and enrichment with minerals and vitamins. Fungi reproduce well in an environment with a high content of the following substances:
- lactose;
- glucose;
- acetic acid;
- mannose.
All components are contained in the remains of fruit and vegetable products. After the mushrooms have propagated, they must be collected, dried and ground into dust. The additive is combined with feed and given to pigs.
Pros and cons of use
Yeasting feed has a number of advantages:
- The body of a piglet or adult pig is enriched with minerals and vitamins, which strengthen the skeletal structure, accelerate development, and increase weight gain.
- Regular consumption of cultured feed cures boars from sexual dysfunctions and sows from hormonal imbalance. This leads to increased farrowing and easier birth process.
- Feeding pigs with yeast feed is necessary to obtain viable offspring and increase farrowing. Lactating sows are able to provide their cubs with a sufficient amount of milk, which reduces the cost of milk replacer.
The negative side of cultivating a yeast supplement is the complexity of its production and the need for a precise selection of dosage. To produce yeast, it is necessary to allocate a separate laboratory with a temperature of +21…25 OWith a good ventilation system.
It is important to prevent the spread of fungi throughout the room; this requires regular cleaning and repairs. All these manipulations require additional financial costs.
You will also need labor or special mechanisms that will mix the yeast mixture.
Varieties
There are several types of feed additives. They can be:
- Classic feed - obtained from the remains of alcohol products.
- Hydrolytic - made from food and wood waste.
- Special concentrates - rich in protein and vitamins. Separate derivatives of petroleum products and ethanol are used as raw materials.
During the production process, they resort to the use of acetic acid and monosaccharides extracted from vegetable/fruit products. Yeast cultivation is considered a complex technical process, but less money is spent on it than on the production of compound feed.
Feeding rates
The dosage is different for each animal, it depends on the subspecies and health of the animal. Correct dosing is necessary to meet the pig's individual needs. The norm is determined separately:
- Pigs fattened for bacon production should consume no more than 5.5% of the weight of the product fed. This supplement is a high-quality alternative to skim milk.
- Little pigs fed on ethyl alcohol waste need to consume 11% of the total amount of food.
- Active breeding boars need to consume 350-650 g of feed yeast daily. They are necessary to enhance sexual activity and strengthen their reproductive function.
- During pregnancy, sows need to be provided with a sufficient amount of mineral and protein supplements. It is added to feed and given to the sow every day. The dose is determined from 11 to 20% of yeast per daily feed requirement.The product supports the pig's body, increases the number of embryos at the stage of cell division, and improves the health of newborn piglets.
- Lactating sows need to consume 2.5-11.5% of the total feed dosage.
Yeast supplements can be added to complementary foods for small pigs. It is added gradually so as not to provoke eating disorders and allergic reactions. Animals are given 100-150 g of the supplement daily, then the dosage is increased every 3 days.
How to give yeast to pigs
There are instructions for mixing food with yeast. This can be done in several ways:
- In the form of a dough. To do this, take boiled water (1 bucket), yeast (100-250 g), food (3-4 kg). After stirring, the homogeneous mass is infused for 5 hours in a warm place, stirred periodically. After 5 hours, the mass is mixed with food (10-15 kg), warm water (20-30 l).
- By kneading. To do this, mix the entire amount of feed, water and yeast. The liquid is mixed with additional water (30-35 l), left for 10 hours.
- In the form of sourdough. The food is poured with water, mixed with yeast, left for 8 hours and stirred periodically.
Yeasting of feed carried out at home helps to improve metabolic processes in pigs, strengthen their immunity, and increase body weight. The supplement saturates the animal’s body with proteins, fats and carbohydrates. Yeast feed accelerates the growth and development of pigs, which leads to a reduction in financial costs for their maintenance.
