Production of turkeys in the region of Hrvatsko zagorje began in second half of 16th century, when there was a little influence of other turkey breeds from other region. Recently, interest for protection and preservation of autochthonous poultry breeds in Croatia is growing and in that sense this investigation was set to determine the phenotypic traits of Zagorje turkey. One hundred 10-month old turkeys (5 males and 20 females of four strains (bronze, black, grey and pale) were measured, while egg production data were collected by a poll among the breeders. Average body weight of bronze, black, grey and pale strain males were 7.08, 6.88, 6.10 and 6.09 kg, respectively, while in females the average values were 4.02, 4.07, 3.63, and 3.68 kg. Generally, according to body measures of male birds, other than body weight, of all of the strains of Zagorje turkey, the black one is the biggest, as it had the highest values for body length, length of sternum, length of drumstick, length of shank, depth of chest and head measures. At the same time, the bronze strain had the highest value for carcass width. Body measures mentioned previously were not so different in females. Number of reared chicks was lowest in the pale strain. From the body measures assessed it is possible to conclude that Zagorje turkeys are rather uniform within the strain but differences in most of the breed traits are present between the strains, especially in males of bronze and black strain, when compared to gray and pale strain.
