(57) Abstract:

Purpose: the invention relates to agriculture and can be used for growing of agricultural animals and birds. The inventive premix containing vitamins, minerals, impose additional bis(benzoylmethyl)selenide in an effective amount. table 2.

The invention relates to agriculture and can be used for growing of agricultural animals and birds.

Known premix containing filler, mineral substances, trace elements, and vitamins and selectarray component.

The disadvantages of this premix are: insufficient preservation of vitamins, uneven distribution in premixes, bad peremeshivaemogo bulk ingredients, for introduction into the premix requires dilution in fats.

The technical result of the invention is the simplification of the preparation of the premix and the expansion of the range.

This technical result is achieved in that the premix containing vitamins, minerals and selectarray component as the latter contains bis(benzoylmethyl)selenol. the-yellow insoluble in water and is easily mixed with bulk products. The product contains 25 wt. selenium in terms of elementary, to facilitate uniform distribution in relation to selenium. In addition, the technology of synthesis of DAFS-25 is much easier synthesis of selenopyran that simplifies the technology of obtaining the final product of premix and reduces its cost.

There is no need to dissolve DAFS-25 fat in several stages, which also simplifies the technology of preparation of premix containing selenium, and expands the range of premixes, which can be entered selenium in the form of DAFS-25. These premixes can be all known. The number entered in premixes, DAFS-25 may vary, firstly, depending on the animal species for which the premix is intended, and secondly, depending on the content of selenium in natural feeds. It was established experimentally that the content of selenium in the soil in different regions varies. Accordingly, the content of selenium in different feeds in different regions different from each other. Therefore, the addition of DAFS-25 in premixes should take into account the fact that in General the feed contained the optimum amount of selenium, namely: from 0.28 to 0.9 mg / 1 to the premixes were experiments with broilers and pigs, which was added to the feed standard premix similar premix containing DAFS-25 and introduced into the feed of DAFS-25 directly. According to the results of experiments it was determined that the most effective is the use of the premix with the addition of DAFS-25. The results can be explained by the fact that due to the antioxidant properties of DAFS-25 is ensured the safety of vitamins premixes, vitamins together with DAFS-25 stimulate body processes antiradical protection and affect its antioxidant system.

Example 1. To test the validity of premixes in Saratov one "Zorinsk" were formed three groups of 5 thousand heads per diem broiler cross "broiler-6" single party.

All Chicks were fed the same basic diet (PR), appropriate for nutritional and biological value standards of agricultural Sciences. Chicks first group received from the first to the thirtieth day of the ER with the addition of 1% premix P5-1. From the thirtieth day in the sixties, this group received the PR with the addition of the premix P1-1.

The second group of Chicks received from the first to the thirtieth day of the ER with the addition of 1% premix P5-1, which was introduced by DAFS-25 in the amount of 160 mg per kg of premix.

Since the thread is Yah.

The third group of chickens throughout the experience, i.e. from the first to the sixtieth day received only'OR entered directly in the preparation of DAFS-25 from this calculation that the content of elemental selenium in the diet was the same as in the second group.

The results of the experiment are presented in table.1.

Example 2. Conducted comparative tests determine the effectiveness of premixes and feed with selenoorganicheskikh additives for pigs. Were formed three groups of piglets months of age 100 goals each.

All groups were given the same food. The first group in the feed was added 1% standard premix P1-7 OST 59-20-77. The second group in the feed was added to the premix P1-7 with the addition of DAFS-25 in the amount of 160 mg per kg of premix, third DAFS-25 was injected directly into the main diet in the amount of 1.6 mg / kg feed.

The results of the experiment conducted within 60 days, are presented in table. 2.

Thus, in the result of the experiments that the use of a premix containing DAFS-25, more efficient than using the same premix without selenoorganicheskikh connection or addition of DAFS-25 directly into the feed without, trichosis the fact that as selectabase component it contains bis(benzoylmethyl)selenide in an effective amount.
