При этом отмечалось достоверное повышение содержания в молоке животных-продуцентов rhLF массовой доли белка, лактозы и СОМО. Установлено, что показатель количества соматических клеток (КСК) в молоке коз-продуцентов rhLF не носил постоянный характер, а его среднее значение по данной группе было ниже, чем у контрольной.</p></abstract><trans-abstract xml:lang="en"><p>Comparative analysis of physical and chemical parameters of milk obtained from goats producing human lactoferrin and non-transgenic animals showed no differences in milk performance, fat mass fraction and number of somatic cells between the groups. At the same time there was a significant increase of protein mass fraction in milk of animals producing rhLF, as well as lactose and nonfat milk solids. It was determined that the indicator of the number of somatic cells (CSC) in milk of goats producing rhLF was not constant, and its average value for this group was lower than in the control group.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>козы-продуценты</kwd><kwd>лактоферрин</kwd><kwd>молоко</kwd><kwd>соматические клетки</kwd><kwd>физико-химические показатели</kwd></kwd-group><kwd-group xml:lang="en"><kwd>producing goats</kwd><kwd>lactoferrin</kwd><kwd>milk</kwd><kwd>somatic cells</kwd><kwd>physical and chemical parameters</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">Milk composition studies in transgenic goats expressing recombinant human butyrylcholinesterase in the mammary gland / H.
