ABSTRACT
The influence of different contents of vitamins and minerals in practical diets on performance
indices was evaluated on 300 medium type BUT-9 turkeys divided into two groups, 3 replicates,
consisting of 25 toms and 25 hens in each.
Practical diets used in both groups differed only in the content of vitamins and trace minerals
added: lower in group L, higher in group H.
The turkeys of group H were characterized by a higher live body weight (females at 15 weeks by
- 4.3%, and males at 22 weeks - by 8.3%), consumed less feed, crude protein and AMEN per 1 kg of
live body weight, lower mortality and carcass dressing percentage and breast muscle content. Toms of
this group slaughtered at 22 weeks, had more leaf fat in the body.
