Abstract
This article is a narrative about application of the USA fodder quality testing system in Russia. Merits and demerits of the American system of an assessment of hay quality are considered. The Leningrad interregional veterinary laboratory (IVL) adapted principles of this system and has extended to all kinds of bulky feeds. It is recommended to check IVL model experimentally, to discuss and to consider on ТК 130 "Fodder production" as the project of GOST Р "Forages. A method of energy value definition". In the second case, on an example of the assessment sheet sent by the American testing laboratory, the ration of feeding a dairy cow at JSC "Dmitrovskie dairy farms", created according to the American model, is considered: assortment, quantity and quality of forages; the actual and demanded content of nutrients in a ration; relative parameters and ratios of nutrients; ration cost indexes. For comparison of standards of National research council (NRC) of the USA on consumption of dry matter, concentration of rumen degradable and nondegradable protein are compared with norms All-Russian Research Animal Husbandry Institute. Discrepancy of calculated parameters testifies to necessity of their experimental corroboration.
