| Description
| - The goal of the study was to test the possibility of raising milk zinc (Zn) concentration by increasing the supplementation of Zn, and to assess the effect on the somatic cell count. The experiment included 40 dairy cows, assigned to either an experimental (E, n = 20) or a control group (C, n = 20). The experimental group was supplemented Zn in chelate form (440 mg). Blood and milk samples were taken at the start and at the end of months 1, 2 and 3. The average milk Zn concentration during the experiment was 57.36  10.54 mol.l-1, ranging from 38.02 to 86.13 mol.l-1. A trend towards a positive effect of Zn supplementation on the health of the mammary gland was identified in association with the somatic cell count, which was significantly lower in the experimental group (114.90  68.7 .103.ml-1 vs. 208.60  148.1 .103.ml-1; p0.05) by the end of month 3. A negative correlation was found between the somatic cell count and Zn concentrati

- Cílem práce bylo ověření možnosti zvýšení koncentrace zinku v mléce zvýšenou suplementací tohoto prvku do krmné dávky ve formě chelátu a zhodnocení vlivu zvýšené suplementace zinku na počet somatických buněk v mléce. Sledování bylo realizováno v chovu českého strakatého skotu o celkové kapacitě 500 ks dojnic a průměrné dojivosti 6390 l. Do pokusu bylo zařazeno celkem 40 dojnic, které byly na principu analogických dvojic (užitkovost, fáze laktace) rozděleny na skupinu pokusnou (E, n = 20) a kontrolní (C, n = 20). Krmná dávka byla u obou skupin dojnic shodná. Pokusné skupině byl přidáván Zn ve formě chelátu (Bioplex Zn, Alltech Inc. Nicholasville, KY) v dávce 440 mg Zn na kus a den. Na začátku pokusu a dále na konci 1., 2. a 3. měsíce pokusu byly odebírány vzorky krve a mléka. Koncentrace zinku v krevní plazmě a v mléce byla stanovena metodou plamenové atomové absorpční spektrofotometrie. Suplementace zinku ve formě chelátu do krmné dávky dojnic neovlivnila koncentraci zinku v krevní plazmě ani v ml (cs)
