Short summary
This study explores the potential of using cull ewe meat to enhance the value of traditional sheep meat products, focusing on the Tunisian dried meat "kaddid". Two local sheep breeds, i.e. Noire de Thibar (NT) and Barbarine (BR), were evaluated at two slaughter ages (3 months and 5 years). Results showed that BR raw meat had more antioxidants (α-tocopherols) and healthy fats; however, kaddid from NT ewes had higher tocopherol levels, with favourable polyunsaturated fatty acid (PUFA) profiles.

The study evaluated the effects of crude protein levels (high: 16 %, low: 11 %) on meat traits and fatty acid (FA) profiles of three sheep breeds. Only the breed type affected the FA profile: palmitic acid (C16:0) was higher in Queue Fine de l'Ouest (QFO), while stearic acid (C18:0) was higher in Barbarin (BB) and Noire de Thibar (NT). Polyunsaturated fatty acids (PUFAs) and PUFA/saturated fatty acid (SFA) ratio were higher in BB. Health indices were favorable in BB and NT.

Oak acorn diets fed to lambs during the pre-weaning period did not negatively affect their future growth performance. Replacing barley grain with oak acorn in concentrate during the post-weaning period had no effects on a lamb’s growth performance, health and viability. Oak acorn can replace up to 40 % of barley grain in finishing feedlot lamb diets. The substitution of oak acorn for barley has no effects on carcass traits.
