Abstract
ABSTRACT The purpose of this study was to determine live weight and body measurements of male and female native ducks raised in different raising systems. One hundred and twenty native ducks (60 males, 60 females) were used in the study. The ducks were raised in deep litter floor and cage systems. Live weight and body values were measured every two weeks, until they were 56 days old. Three-parameter logistic regression and Gompertz model were used to determine growth model of [...]

Protein sources obtained from poultry have a great importance in human nutrition
The highest value of coefficients of determination was observed in males farmed in cage system (CS) (0.95) in both models, whereas the lowest value was observed in females farmed (0.91) in deep litter floor (DLF) (Figures 1 and 2)
Live weight values of ducks raised in DLF in the 4th, 6th, and 8th weeks were higher than those of ducks raised in CS
Summary
In addition to other poultry, it is required to develop sources of duck raising and conduct studies on production of these sources in a more economical way for humans to eat well. Even though chicken is the primary among poultry species raised in Turkey, duck raising is performed. There are different raising systems for ducks. These systems are divided into three groups; freerange (extensive), semi-intensive, and intensive. Intensive system includes deep litter and cage systems. In these systems, ducks are farmed in a closed room in such a way to provide appropriate air conditioning and ventilation as is for chicken (Rodenburg et al, 2005)
