ABSTRACT

Background and Aim: Black cumin meal (BCM) is the principal by-product that can be obtained from black cumin seed (Nigella sativa L) after the oil is removed from the fruit and represents 70-75% of the fruit weight. The aim of this experiment was to assess the influence of feeding BCM on the carcass characteristics and meat quality of growing lambs.

Materials and Methods: Twenty-four Awassi lambs were randomly divided into two dietary treatments. The lambs were penned individually in single pens and provided access to ad libitum feed and water. The dietary treatments were no BCM (control [CON]; n=12) or 150 g BCM/kg (BCM 150; n=12) of dietary dry matter.

Results: Lambs fed BCM had greater (p≤0.01) fasting live BW, and hot and cold carcass weights. Leg fat and eye muscle depth were lower (p≤0.05) in CON versus BCM lambs. Meat whiteness (L*), redness (a*), and yellowness did not differ between lambs fed the two diets.

Conclusion: The inclusion of BCM improves lamb carcass characteristics, but does not affect lamb meat quality.
