Description

The invention relates to the field of animal husbandry, in particular to pig farming, and is intended to increase the milk productivity of sows.

The purpose of the invention is to increase the milk productivity of sows using the Selmik complex preparation. In addition to malt sprouts, cobalt, copper, manganese, zinc, the preparation additionally contains an organic form of selenium, and the components are taken in the following amounts, g per head per day: malt sprouts - 300; cobalt chloride - 0.033; basic carbonic copper - 0.106; basic manganese carbonate - 0.281; zinc carbonate basic - 0.441; potassium iodide - 0,00057; sodium thiosulfate - 0.0001; the organic form of selenium in the form of selenmethionine and selenocysteine is 1.0. This drug provides an increase in multiple pregnancy, large-fruited piglets, sows milk, as well as growth and development, the safety of piglets for weaning (table 2, 3).

The invention relates to pig farming, in particular to preparations for pigs, and can be used to increase the milk production of sows.

A known method of increasing the productivity of young pigs, including a single implantation of iodine under the skin of an animal, but it does not meet the needs of the animal in other macro- and microelements [1].

There is a method for the prevention of hypomacro- and microelementoses, which helps to increase productivity by normalizing mineral metabolism, using mineral additives based on inorganic salts, which are absorbed in the body worse than their organic compounds [2].

The purpose of the invention is to increase the milk production of sows.

This goal is achieved by the fact that the proposed method involves the introduction of sows into the main diet during lactation and before insemination, the Selmik preparation containing malt sprouts, carbonate salts of copper, zinc, manganese, cobalt chloride, potassium iodide and its stabilizer, organic selenium in the form of selenmethionine and selenocysteine.

The complex of minerals - carbon salts of copper, zinc, manganese, cobalt chloride, potassium iodide and its stabilizer, organic selenium in the form of selenmethionine and selenocysteine - allow you to balance the diet according to the content of minerals and vitamins in an accessible form.

The method is as follows.

Example 1. A study is conducted of the effectiveness of various formulations of the drug. Testing of the Selmik preparation is carried out under experimental conditions on sows of large white breed at the age of 2-4 years. To work out the dose and effectiveness of the drug, 4 groups were formed, in each group 12 sows. Sows in the control group received a basic diet based on concentrates. The optimal dose of the drug was established experimentally for sows, taking into account the nutritional value of diets and the need of animals for nutrients. Sows in the experimental groups received the Selmic preparation in the doses (in% of the daily feed intake) to the main diet: in the first - 4.0, in the second - 5.0, in the third - 6.0, in the fourth - 7.0 , in the fifth - 8.0 (Table 1). Selmic was fed to sows with concentrates daily in the morning, during lactation and until insemination.

The effectiveness of the drug is determined by the productivity indicators of sows: multiple pregnancy, large fruit, milk production, weight of the nest after weaning and the safety of piglets. The results are presented in table 2.

As can be seen from table 2, the use of the drug "Selmik" provides higher rates compared to control. So, multiplicity and large-fruited piglets, sows milkiness significantly increase. The preferred amount of the drug is 6% of the daily feed intake.

Example 2. Conduct a comparative study of the effectiveness of the claimed drug on newborn piglets obtained from sows of the compared groups. The effectiveness of the drug is determined by the live weight of piglets at birth and by the time of weaning, the total weight of the nest for weaning, the average daily gain, as well as the safety of piglets for weaning. Observations last 60 days. The results are presented in table.3.

From table 3 it follows that the proposed drug increases growth rates, the safety of piglets for weaning. The best growth and preservation of piglets for weaning in the experimental groups indicates the positive effect of the Selmic preparation on the body of lactating sows. The preferred amount of the drug is 6% of the daily feed of lactating sows.

Example 3. The dynamics of changes in biochemical blood parameters is studied using the proposed method for increasing the productivity of sows. Control animals are not fed with the drug. Blood sampling is carried out after weaning piglets. The results are presented in table 4.

A comparison of the biochemical parameters of the control and experimental groups shows the normalization of the calcium-phosphorus ratio, alkaline reserve, an increase in the level of total protein due to an increase in the level of γ-globulins.
