Carcass composition and visceral organ mass of broiler chicks fed different levels of olive pulp \

الملخص EN

The current investigation was conducted to study the effects of olive pulp on the carcass composition, gastrointestinal tract, and visceral organ mass of broiler chicks.

A total of 250 one-day-old chicks were used in this research and were divided into five experimental groups with five replicates in each.

Olive pulp was incorporated in four of the experimental groups at rates of 25, 50, 75 and 100 g/kg in both starter and finisher feeds to replace similar amounts of maize.

Diets were fed for 35 days.

At the end of the experiment, four birds of each group were slaughtered in similar routine followed in regular slaughterhouses.

Regression analysis (linear and quadratic) showed that level of olive pulp had no significant effects on visceral organ mass, gastrointestinal tract weight, carcass cuts, carcass composition, and dressing percent.

However, chicks consuming 100 g olive pulp/kg had heaviest (P<0.05) average live weights.
