RESPONSE OF GROWING TURKEYS TO SUPPLEMENTATION OF DIFFERENT TYPES AND LEVELS OF NATURAL FEED ADDITIVES·

The objective of this experiment was to evaluate the response of
turkey poults to different types and levels of natural feed additives (NFA) such
as hot or black pepper and canena feed at levels 0.2 or 0.4% considering
growth performance, carcass traits, blood parameters and the economic
efficiency.
A total number of 168 unsexed eight-weeks- old Broad Breasted
Bronze turkey poults were randomly distributed to seven treatment groups of
24 birds each. Each group contained 3 replicates, of 8 birds per replicate.
Then, initial live body weight among replecats as well as treatments was
nearly similar. The first group served as control, while the other groups were
assigned on one of two levels of tested NFA.
Data revealed that adding NFA i.e, hot or black pepper or canella to
the control diet significantly improved live body weight. body weight gain and
feed intake while, decreased feed conversion efficiency as compared to those
led the centro'. Results indicated a significant decrease in dressinq, heart and
gizzard percentages of turxey poults the supplemented NFA as compared to
those fed the control diet. dier plasma total protein, albumin glObulin contents
were significantly increased when hot pepper was fed at 0.4%, while plasma
total lipids significantly decreased Either hot or black pepper and canella had
no adverse effect either on plasma cholesterol or alkaline phosphatase.
It is concluded that using hot paper or canella at 0.2 or 0.4% may
enhance the productive performance with no adverse effects on blood
parameters of turxey poulls
