This paper compares the growth patterns of chickens, turkeys, ducks and geese. The growth curves and their parameters were estimated by the Richards function. In this work, weight data of females of current sire lines (62 chickens, 47 ducks and 42 geese) and commercial medium-type hybrids (27 turkeys) were used. Birds were fed ad libitum and weighed at 7 or(More)
Growth curves based on the Richards function are evaluated for four highly inbred tines of fowl (F, > 99.9 p. 100) and some of their F, hybrids. The largest deviations of the estimated course of growth (maximum : 9.3 p. 100) in terms of live weight occurred before 6 weeks of age ; inbred and hybrid groups showed a tendency to deviate in opposite direction(More)
