Growth and Drawing Weight in the Broiler's Breeds

The growth and feed conversion of broiler's breeds was studied comparatively with Barred Plymouth Rock (B.P.)×Single-comb White Leghorn (W.L.)F_1 ♀, S.c. Rhode Island Red (R.I.)×S.c. White Leghorn (W.L.)F_1 ♀, Fukuda 307 ♂ and ♀, S.c. Rhode Island Red (R.I.)×Vantress F_1 ♂ and ♀and White Cornish ♂. The experimental results are given in Table 1, 2 and 4. From Table 1,2 and 4, it is clear that the growth and feed conversion show difference apparently, but the drawing weight gives no evident difference in the broiler's breeds.
