This study aimed to explore how hybrid varieties impact broiler
chickens' production and slaughter performance. We applied standard rearing
techniques over a 42-day period. The trial involved a total of 420 broiler chickens
of the following hybrids: Cobb 500 and Ross 308. Weekly performance tests were
conducted, assessing average daily gain, feed consumption, feed conversion rate,
mortality, and European Poultry Efficiency Factor. After controlling for final
body weights on the 42nd day, a random sample of 12 broilers per genotype, with
an equal gender distribution, was selected for slaughter parameter analysis.
Following slaughter traits were determined: pre-slaughter weight of chickens,
slaughter yield, share of abdominal fat, chicken thigh circumference, and chest
angle. The results revealed no significant difference in food consumption between
the examined hybrids. Chickens of the Cobb 500 genotype exhibited significantly
higher (p<0.01) gain and a more favorable feed c...onversion rate. Due to its better
vitality, feed conversion rate, and gain, Cobb 500 chickens demonstrated
significantly higher (p<0.01) European Poultry Efficiency Factor values. In
contrast, Ross 308 chickens displayed statistically significantly lower (p<0.05)
slaughter yield and chest angle values. At the same time, the proportion of
abdominal fat and chicken thigh circumference showed no significant difference
between the tested hybrids.
