Phytoncides in the prevention and therapy of blackhead disease and their effect on the turkey immune system

Mean values of production parameters and the mortality and culling rate in the laying production period (week 32 to week 56 of life) in a reproductive flock of turkeys treated for histomonosis diagnosed in the rearing period

Parameter		Turkey house
Parameter	P-1	P-2	P-3
Eggs/hen	112	117	119
Mortality and culling (%)	6.1	2.7	3.4

Fertility (%)		97
Hatchability (%)		85

[i] P-1 – the poultry house used to hold hens from J-2 where there was an outbreak of clinical histomonosis during the rearing period

P-2, P-3 – the poultry houses used to hold hens from J-1 and toms from J-2
