The mineral elements interact not only among themselves, but also with the organic components during complex metabolism process. Identifying the features of the feed nutrient substances relationship allows you to direct the body’s metabolism in the direction of their effectiveness and to obtain the maximum output from the animals. The experimental part of the work was carried out on poultry complex “Agrofirma Zalesnyy” of the Republic of Tatarstan from January to May 2016. The objects of research were female turkey-broilers of “Hybrid Converter” cross, mineral supplement “Tseostimul”, probiotic “Provagen” and symbiotic preparation of a new generation. With this aim, four groups of turkey were formed of 40 heads. The first group was a control one and received a basic diet, adopted by the poultry farm. The second group received the basic diet, added with mineral supplements with a dosage of 30 gramm per 1 kilogramm of feed. Turkeys of III-experimental group was added to the diet of probiotic preparation “Provagen” at a dose of 3 gramm per 1 kilogramm of feed. The turkeys of IV-test group received in addition to the basic diet a symbiotic drug rate of 20 gramm per 1 kilogramm of feed. The main diet was consisted of complete feed. Duration of the experiment was 112 days. By the end of the experiment the body weight of experimental groups exceeded the similar index: in the control group to 1082 gramm (р ≥0,001), in the first test group to 781 gramm (р ≥0,001), in the second test group to 1339 gramm (р ≥0,001), in the third group with addition of symbiotic drugs or to 12.3%, 8.9% and 15.3% respectively. The numbers of leukocytes was decreased from 34.2 109/L to 33.3 109/L in I experimental group, to 33.2 109/L in II and to 34.4 109/L in IV experimental group. The mass of internal organs was significantly higher in females of experimental groups. Thus, the weight of the liver of experimental groups was greater to 12.3%, 8.9% and 15.3%, compared with the control group.
