Effects of Zinc Glycine Chelate on Growth, Hematological, and Immunological Characteristics in Broilers

“…Consistent with our results, a number of researchers documented that dietary zinc supplementation increased feed intake, growth rate, and feed efficiency in broiler chicks [15][16][17][18] and quail [19]. Reports show that diets with low zinc lead to depressed appetite, resulting in decreased feed intake and reduced weight gain [20][21][22]. Zinc is required for the biological function of more than 300 enzymes.…”

The trace element and humoral immune response of lambs administered a zinc, cobalt and selenium soluble glass bolus

“…This is likely due to competition between zinc and copper for intestinal metallothionein (Swinkels et al, 1994) and the bolused sheep having more zinc potentially available for absorption with a similar copper concentration available.…”

Effect of Physical Activity on the Hair Content of Macro and Trace Elements in Young Women

“…При этом нельзя не отметить известные данные, что у спортсменов дефицит цинка встречается довольно часто и сопровожда-ется снижением аппетита, аллергическими прояв-лениями, дерматитами, дефицитом массы тела, снижением остроты зрения, выпадением волос (Grantham-McGregor, Ani, 1999;Braetter, 2002). Важно, что при дефиците цинка специфически снижается Т-клеточное звено иммунитета, и это повышает вероятность простудных и инфекцион-ных заболеваний, а также реабилитационный пе-риод после травм (Sandstead, 1991;Swinkels et al, 1994;Оберлис и др., 2008).…”
