The article examines the effect of feeding complete ration compound feed with different ratios of lysine and methionine on the productivity of young turkeys. Experimental studies were performed on young turkeys of the "Big-6" cross-breeding meat direction. By the method of balanced groups, five sub-experimental groups of birds were formed at the age of one day. The experiment lasted 126 days and was divided into two periods: comparative (7 days) and main (119 days). During the comparative period, the experimental turkeys consumed compound feed of the control group. In the main period of the experiment, the share of methionine relative to lysine in compound feed decreased or increased by 5 or 10% according to the periods of cultivation.
It was established that the different ratio of lysine and methionine in compound feed for young turkeys affects its productivity in different ways. So, at the age of 126 days, turkeys that received compound feed with an increase in the proportion of methionine relative to lysine by 5 and 10% had the highest live weight – they outnumbered the counterparts of the control group by 5.9 (Р<0.05) and 3.6%, respectively. The turkeys, which consumed compound feed with a reduced share of methionine relative to lysine by 10 and 5%, were inferior to the control peers by 4.4 and 2.2%, respectively, according to the mentioned indicator. Increasing the proportion of methionine relative to lysine by 5 and 10% in compound feed for turkeys at all stages of their growth contributes to a reduction of feed costs per 1 kg of live weight gain by 4.5 and 2.2%, respectively.
It is proved that the relationship between the ratio of lysine and methionine in compound feed for young turkeys and its costs per 1 kg of live weight gain is described by a polynomial line with a reliable approximation coefficient R2=1.
Correlation analysis shows that there is a reliable (р<0.05) strong inverse relationship between these two indicators (rs= – 0,9).
The rate of preservation of poultry in all experimental groups was close (94-96%), however, the probable influence of different ratios of lysine and methionine in compound feed for growing poultry on the rate of its preservation was not established.
