PHYSIOLOGICAL AND BIOCHEMICAL STATUS OF COWS IN CASE OF INTRODUCTION OF A SILICON-CONTAINING SUPPLEMENT INTO THEIR RATION

The article raises questions about development of organic food market in Russia. One the options for obtaining livestock products by using silicon-containing natural minerals as feed additives is proposed. main carrier supplement a highly activated zeolite, filler an amino acid complex animal origin, 100 % product. work was carried out Ulyanovsk region at OOO “Agrofirma Tetyushskoye” on dairy cows black-and-white breed. There were two groups, 10 each selected: according to live weight, age, productivity, physiological state. first group (control) received only ration accepted farm. As second (experimental), additive based modified zeolite enriched with acids included once day dose 250 g per cow. All animals kept same conditions, there stable housing. In course experiment, improvement morphological composition cows’ blood and nitrogen metabolism parametres revealed when introduced into ration. promoted increase of: erythrocytes 14.38 %, hemoglobin - 12.17 (p <0.05), leukocytes 20.44 <0.01); total protein 11.84 albumin 11.11%, globulins 12.24 %; decrease urea 22.22 ALT activity 8.0%. general, show intensification effective usage synthesis processes body, including milk synthesis.
