| Abstract | ||
| This study was conducted in poultry research station in animal resource department/ State Board of Agricultural Research/Ministry of Agriculture, from 18/7/2011 to 25/10/2011 on 28 sire and 252 dam from broiler breeder from two strains Ross-308(RR) and Arbor Acres (AA) and It combination A.R and R.A and Its progeny (1503 chicks) to estimate crossbreeding parameters of broiler stocks, for production, gut, and certain biochemical traits. The results showed that there were Significant differences for body weight among treatments and significant differences for weight in marketing age for hybrid resulting from the Ross sire and dam of Arbor Acres (third treatment R.A) resulting the highest weight in the marketing age. The first A.A and the third R.A treatments achieved significant improvement for total feed conversion ratio over other treatments. The mortality percentage did not achieve any significant differences among different treatments and for values of economic figure and production index for all treatments. There are significant effects for sex for individual weights for treatments throw the period of experiment in which males significantly different from females in different ages. The results showed significant differences among four treatments in weights of proventiculus, spleen, pancreas, liver, bladder, fabricia gland, lengths of duodenum, jejunum and ileum with existence of significant differences (p≤0.05) for sex in weights and the length of guts. There were no significant differences for biochemical traits (H/L, glucose, albumin, cholesterol, HDL and LDL) on the other hand T.G and VLDL showed significant differences among the treatments and the significant differences for the fourth treatment | ||
