Оценивая удои натурального молока, следует отметить, что за 300 дней исследований от коров I группы надоили 5242,8 кг молока, от II группы - на 7,4 % больше, от III - на 11,4 % и IV - на 14,8 % больше. Целесообразно продолжить углубленные исследования эффективности использования различных норм при использовании разных типов кормления, в том числе и пастбищ.</p></abstract><trans-abstract xml:lang="en"><p>The results of research on the efficiency of the dairy cows feeding standardsin the U.S., NRC (2001), British, FIM (2004), Russian (2003) and the new Ukrainian (2009) in single farm conditions. Estimating yields of milkone should note that during the 300 days of the study group I cows gave 5242.8 kg of milk, group II - by 7.4 % more, group III - by 11.4 % and IV - by 14.8 %. It is appropriate to continue the thorough study of the efficiency of different standards using different types of feeding including pastures.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>корма</kwd><kwd>животные</kwd><kwd>нормы</kwd><kwd>кормление</kwd><kwd>коровы</kwd><kwd>молочная продуктивность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>feeds</kwd><kwd>animals</kwd><kwd>standards</kwd><kwd>feeding</kwd><kwd>cows</kwd><kwd>milk yield</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Feed into Milk.
