Chemical composition of the pearl grey guinea fowl.

1. The growth of the chemical components of the body of the Pearl Grey guinea fowl from hatching till 127 days of age was evaluated in this study. 2. The Gompertz equation is suitable to describe the growth of the different chemical components over time. 3. Body and feather fat, respectively, were estimated by subtracting the predicted weights of all other components from those of body and feather weights. This leads to an overestimation of body fat content, and erroneous estimated values for feather fat.
