Влияние замены ржаных отрубей трепелом на сохранность витаминов в премиксе

Abstract

При изучении нового состава премиксов с использованием минерального носителя взамен пшеничных отрубей трепела месторождения «Стальное» Хотимского района Могилевской области в количестве 30, 50 и 100% отрицательного влияния на сохранность витаминного комплекса на протяжении гарантируемого срока хранения не оказывает, при соблюдении условий хранения и использовании защищенных форм витаминов.

When studying new composition of premixes with mineral carrier instead of Tripoli wheat bran of "Stalnoye" deposit of Khotimsk district of Mogilev region in the amount of 30, 50 and 100% has no negative effect on preservation of the vitamin complex during the guaranteed shelf life subject to observance of storage conditions and use of vitamins’ protected forms. The aim of the research was to determine the vitamin activity of premix during storage. Premixes were produced at the branch "Negorelsky КНР" of OJSC "Agrokombinat Dzerzhinsky". They were dosed in bags of 25 kg and stored at a temperature of 30 ° C and a humidity of 45%. For young animals from 10 to 75 days of age, premixes formulations were developed PKR-1-50 and PKR-1-100, with 50 and 100% of rye bran of standard premix was replaced with zeolite-containing Tripoli. Researches on content of vitamins in them were conducted at the beginning and 3 months after. For young cattle at the age of 75-240 days premixes PKR-2-30 and PKR-2-50 were developed, in which, unlike the control premix PKR-2 based on rye bran, 30 and 50% of the filler was replaced with zeolite-containing Tripoli. Researches on the content of vitamins in them had been carried out for 5 months. Samples were collected once a month. Vitamins іп the premix were determined at SI "CRILhleboprodukt" according to generally accepted methods. When studying new composition of premixes for cattle, where instead of a standard carrier of organic nature - wheat bran, a mineral carrier was used, Tripoli of "Stalnoye" deposit of Khotimsk district in Mogilev region. The mineral component in the premix was administered in the amount of 30, 50 and 100% by weight. It was established that there is no negative effect on the preservation of the vitamin complex during the guaranteed shelf life, provided storage conditions and the use of protected forms of vitamins are observed. It was found that preservation of vitamins A, D3 and E in all the three formulations after five months of storage did not change and corresponded to the declared indicators. Over the past period, the good stability in the experimental premixes was shown by vitamins B2, В5 and Е. The vitamin B1 preservation was the lowest. Preservation of selenium in premixes after five-month storage period made 46% in formulation of PKR-1 and 55% in formulation of PKR-2.
