Leg cuts from Awaasi lambs fed a diet with varying levels of Rhus coriaria L., Physical dissection and chemical composition.

Abstract

This research was conducted in a private slaughterhouse in Samarra from 1/5/2019 to 1/8/2019. Sixteen Awassi lambs were raised with an average body weight (of 20±25) kg and an age of about (5.5 to 6) months. We divided the lambs into four treatments. The first treatment was without additives, called control; the second treatment was 1% Sumac, the third treatment was 3% Sumac, and the last one was the fourth treatment with 5% Sumac. The results showed significant differences between treatments in biceps femoris and semimembranosus muscle (treatment 3 the female) were (180.9±10.66)g, ( 168.4±5.72)g respectively. And a highly significant difference in adductor muscle (treatment 3, the female) was (75.6±2.58)g compared with the control (62.85±5.93)g. significant differences in treatment 3 in Semitendinosus muscle between males and females were( 57.2±3.65) and (74.4±3.02)g, respectively. The rectus femurs showed significant differences between treatments 3 and 4 in females were( 99.6±8.76) and (76.3±6.98)g, respectively. In physical dissection, a low significant difference in treatment 4 in lean was (56.3+3.66)%. The lean percentage in treatment 3 of the female was (59.2±0.99) %. About chemical analysis, the high percentage of moisture in the male in treatments 2,3 and 4 were (72.7±0.14),( 72.8±0.21),(and 72.8±0.21)%, respectively.
