A total of 21,000 broilers was used in four experiments (one experiment per season) to evaluate the grow-out performance and carcass quality of five commercially available broiler crosses. The crosses were Hubbard × Hubbard, Hubbard × H&N, Hubbard × Shaver, Ross × Hubbard and Ross × Arbor Acre. Each experiment consisted of three replicate pens (175 birds/pen) per sex per cross.Egg weight differences for the combined experiments were nonsignificant. However, a summary of the four experiments revealed significant broiler cross differences in both day-old male and female chick weights. Both Hubbard × Shaver and Ross × Arbor Acre crosses had lower percentages of saleable chicks. At 28 days of age, male progeny differed statistically in both body weight and feed conversion. At 56 days, Hubbard × Hubbard and Ross × Hubbard females were significantly heavier than other crosses. Numerically, the combined sexes weighed 2063, 2053, 2019, 2013, and 2003 g for Hubbard × Hubbard, Ross × Hubbard, Hubbard × Shaver, Hubbard × H&N, and Ross × Arbor Acre, respectively. Male and combined sex feed utilization differed statistically at this age. No significant broiler cross differences were found in 28 or 56 day mortality or disease condemnations. Carcass quality, as determined by causes of downgrading, revealed Ross sired male progeny had fewer downgrades due to conformation, breast blisters and breast bruises than did Hubbard paternal crosses. In females, statistical paternal cross differences were found only in conformation downgrades. No significant differences were recorded in fleshing, leg bruises and broken or dislocated bones downgrades.
