Calculations of feed conversion during the growing season indicate that broiler
chickens consuming combined feed containing 75 % of the requirement for
microelement glycinates (Mn, Zn, Fe, Cu) spent 1.5 % less than the control.
The evaluation of the results of broiler chickens’ growing by comparing feed
intake and its conversion into productivity is presented in Figure 2.
CONCLUSION
1.
Multiple studies and practices show that the most effective way to feed all
mineral additives is to make complex mineral mixtures out of them, taking into account
the birds’ needs in mineral elements and their content in feeds. For poultry, mineral
additives in the form of premixes should be added to mixed feeds or concentrated
mixes, based on the physiological-optimal content of nutrients in 100 g (1 kg) of mixed
feed, based on its daily consumption and the needs of birds in microelements.
