Description

The invention is intended for agricultural enterprises manufacturing feed mixtures for pigs.

A known method of increasing the productivity and safety of piglets aged 30-120 days (copyright certificate No. 1824194, class A61K 35/74, 1991 - prototype) [1].

The known method involves daily giving piglets from 30 days of age with food for 60 days a feed additive in the form of a suspension of live culture of strain Bacillissubtilis 534 in 0.9% sodium chloride solution of 300-500 million microbial bodies per 1 kg of live weight of piglets or 10 · 10 ⁹ -20 · 10 ⁹ microbial bodies per feed unit. The microbial mixture is prepared by washing with a 0.9% sodium chloride solution of a 48-hour culture of Bacillissubtilis strain 534 from solid nutrient media to a concentration of 10 billion microbial bodies containing 1 ml.

The disadvantage of this method is the relatively low safety and productivity of piglets after weaning, as well as the difficulty of preparing a feed additive in the form of a suspension of live culture of strain Bacillissubtilis 534 in modern pig keeping technologies.

The objective of the proposed method is to simplify the preparation of feed additives and increase resistance to massive gastrointestinal diseases and edematous disease of weaned piglets, and consequently, increase their safety and productivity.

This problem is solved by the fact that a feed additive is introduced into the feed for piglets, including zeolite in the amount of 7-8% by weight of the feed, the probiotic Proagen from the spore-forming bacteria Bacillissubtilis in the amount of 0.2-0.3% by weight of the feed and glucose 0, 1-0.2% of the mass of feed.

Zeolites are a large group of minerals that are close in composition and property, are able to give and absorb water again, depending on temperature and humidity. Another important property of zeolite is its ability to ion exchange, they are able to selectively separate and reabsorb various substances, as well as exchange cations. As experiments on weaned pigs showed, the introduction of zeolite in the feed composition in the amount of 7-8% of the feed mass provides loosening of food masses in the gastrointestinal tract of piglets and the penetration of digestive juices into the contents of the gastrointestinal tract. When the amount of zeolite in the feed is less than 7-8%, and especially when it is completely absent, feed is gelatinized in the gastrointestinal tract of the piglets, while the digestive juices do not penetrate the food masses, as a result of which fermentation processes occur in the food masses, non-specific and pathogenic microorganisms, which leads to the disease of piglets.

Probiotics are regarded as a live microbial feed supplement that has beneficial effects on the host animal by improving its intestinal microbial balance. “Provagen” refers to the new generation of spore-forming probiotics. The introduction of the probiotic "Provagen" into the feed composition in an amount of 0.2-0.3% by weight of the feed provides its enzymes with the digestibility of feed nutrients in the gastrointestinal tract of piglets.

The use of ready-made preparations of live Bacillissubtilis cultures in the form of the Provagen probiotic from spore-forming bacteria Bacillissubtilis promotes the production of enzymes such as amylase, lipase, peptidase, protease, and others, which enhance the digestion process in the gastrointestinal tract of animals and increase the absorption of nutrients in the feed. The probiotic Provagen from the spore-forming bacteria Bacillissubtilis synthesizes amino acids, vitamins and antibiotic substances in the gastrointestinal tract of animals, which determines their effectiveness in increasing the resistance of animals to massive gastrointestinal diseases and edematous disease of weaned piglets, and consequently their increase safety and productivity.

Glucose is one of the most common carbohydrates, the main "biological fuel" in the human body and mammals. As experiments have shown, the inclusion of glucose in an amount of 0.1-0.2% in the composition of the feed creates optimal working conditions for the probiotic in the gastrointestinal tract of animals.

Before zeolite, probiotic and glucose are included in the feed, they are thoroughly mixed, added to the feed for weaned piglets in the indicated ratio and mixed in the feed.

The feed supplement is fed daily to piglets from 28-30 days old to 90 days old.

The effectiveness of the proposed method was determined in the scientific and economic experiment on 3 groups of weaned piglets from 28-30 days old to 90 days old, 12 goals in a group.

Example 1

Compound feed for weaned piglets of the first group included crushed barley grain - 37.0%, corn - 25.0%, wheat - 21.0%, soybean meal - 5.0% and sunflower - 5.0%, fish flour - 2 , 0%, monocalcium phosphate - 0.35%, table salt - 0.35% and premix - 1.00%, including trace elements and vitamins.

Example 2

Compound feed for weaning pigs of the second group differed in composition from compound feed for weaning pigs of the first group in that instead of the corresponding amount of crushed grain components, they included 7.0% zeolite, 0.2% Probiotic Proagin from spore-forming bacteria Bacillissubtilis and 0.1 % glucose.

Example 3

Compound feed for weaning pigs of the third group differed in composition from compound feed for weaning pigs of the second group in that instead of the corresponding amount of crushed grain components, they included 8.0% zeolite and 0.3% Probiotic Proagin from spore-forming bacteria Bacillissubtilis and 0.2 % glucose.

The daily feed rate fed to piglets of all groups from 30 to 35 days old was 0.250 kg, from 36 to 45 days old - 0.450 kg, from 45 to 60 days old - 0.650 kg, from 65 to 90 days old - 1,200 kg per 1 head .

The daily amount of feed for young pigs of all groups was fed for 2-3 cottages.

Indicators such as feed intake, digestibility ratios of dry matter of the diet, average daily weight gain of animals and the economic efficiency of the proposed method are shown in the table.

Research results Group of animals Differences between groups Eatability of feed,% The digestibility rate of dry matter of the diet,% The average daily weight gain, g Consumption of feed units per 1 kg of growth 1 (control) Compound feed for young pigs 95.5 70.50 ± 0.19 376.6 3.29 2 (experimental) Compound feed with the addition of 7.0% zeolite, 0.2% probiotic from spore-forming bacteria Bacillissubtilis, 0.1% glucose 97.8 73.40 ± 0.55 412.5 3.12 3 (experimental) Compound feed with the addition of 8.0% zeolite, 0.3% probiotic from spore-forming bacteria Bacillissubtilis, 0.2% glucose 98.5 74.10 ± 0.38 428.2 3.06

As follows from the table, the inclusion of 2 and 3 experimental groups from 28-30 and up to 90 days of age in the feed composition of piglets from 7.0-8.0% zeolite, 0.2-0.3% Probiotic Provagen from spore-forming Bacillissubtilis bacteria and 0.1-0.2% glucose led to an increase in feed intake, an increase in the digestibility rate of dry matter of the diet. The average daily gain in live weight of piglets of the 2nd and 3rd experimental groups increased by 9.5 and 13.7%, respectively, while the costs of feed units per 1 kg of live weight gain decreased by 5.2% and 7.0%, respectively, compared to animals of the 1 (control) group.

During the experiment, in animals of the 1st (control) group, signs of gastrointestinal diseases and edematous disease were noted, in animals of the 2nd and 3rd (experimental) groups, signs of diseases were not observed, which allows us to conclude that the inclusion of compound feed for piglets with 28-30 days old to 90 days old 7.0-8.0% zeolite, 0.2-0.3% probiotic Proagen from spore-forming bacteria Bacillissubtilis and 0.1-0.2% glucose increases the resistance of piglets to gastrointestinal diseases and swollen swine disease, safety, as well as porosity Yat 28-30-day age.

When using the proposed method under production conditions for growing weaned piglets in the first months of life as a result of gastrointestinal diseases and edematous disease, the safety of piglets was 90-93%. When fed to weaned piglets from 28-30 to 90 days of age, the proposed feed additives, including zeolite, Probiotic probagen from spore-forming bacteria Bacillissubtilis and glucose, the safety of piglets increased by 7-8%.
