Abstract
In the article, results of researches on an establishment of an optimum source of Manganese, Zinc, Iron and Copper are resulted. Different source Manganese, Zinc, Iron and Copper was additionally added mixed fodder for ducklings grown for meat. Experimental studies conducted in terms of problem research laboratory of feed additives National University of Life and Environmental Sciences of Ukraine. Independent experiment was conducted with growing meat ducklings. We conducted a randomized block experiment with 5 treatments, each with 4 replicates of 25 growing ducks (1 to 42 d of age). A diet consisting of corn, soybean and sunflower meal, fish meal, premix (22.5% CP, 2.92 kcal of ME/g on 1 to 14 d of age, 18.5% CP, 2.90 kcal of ME/g on 15 to 42 d of age) having severally Manganese, Zinc, Iron, Copper at sulphate, glycinate and citrate. The premix was formulated to contain the requirements of trace elements in combination of either inorganic (sulphate form) or organic form (glycinate and citrate form). Diets were supplemented with the organic form of zinc, copper, manganese or iron at the rate of 100% or 75% of the total requirements of the elements. Diets and water were offered ad libitum. After 6 weeks of dietary treatments the growth performance (feed intake, body weight, daily gain, feed conversion, homogeneity of the poultry) were affected by dietary treatments. Results indicated that chicks fed diets containing 100% organic minerals (Mn, Zn, Fe, Cu) had significantly higher body weight, better feed conversion compared with those of inorganic control minerals treatment. Use of fodder for ducklings, which are grown for meat glycinate Mn, Zn, Fe, Cu versus sulfate improves their productive performance. The body weight of ducklings at 42 d of age is more by 1.6% (P < 0.05) and the conversion of feed is 1.0% higher. The conversion of feed from consumption was rather high (R2=0.84), which confirms the change in the productive indicators of duckling from the feed factor.

Summary
I.I., Holubiev, M.I., Otchenashko, V.V., & Makhno, K.I. (2018). Productive qualities of ducklings with different normalization methods trace elements in the diet. Наведено результати досліджень з встановлення оптимального джерела Мангану, Цинку, Феруму та Купруму, який додатково вводять у комбікорми для каченят, яких вирощують на м’ясо. Ключові слова: каченята, маса тіла, комбікорм, неорганічні і органічні джерела мікроелементів. (Bao et al, 2007) досліджували різні рівні і джерела мікроелементів (Cu, Fe, Mn, Zn) і дійшли висновку, що додавання 4 мг Cu та 40 мг кожного з Fe, Mn і Zn з органічних джерел може бути адекватним рівнем для вирощування курчатбройлерів. Метою нашого дослідження було вивчення впливу мінеральних добавок Мангану, Цинку, Феруму та Купруму з різних джерел у комплексі та за умов їх різного рівня з органічних джерел на зоотехнічні показники каченят, яких вирощують на м’ясо
