Abstract
Our objective was to evaluate the effects of feeding sesame hulls (SH) on carcass characteristics, meat quality, and the fatty acid profile of meat in lambs. Twenty-four male lambs (initial body weight = 21.8 ± 1.35 kg; age = 75 ± 2.5 d) were randomly assigned to three dietary treatments. The CON group received 0 g/kg of SH, whereas the other two groups were given either 75 g/kg (SH75) or 150 g/kg (SH150) of SH on a dry matter (DM) basis. A 10-d acclimatization period preceded the 110-d feeding trial used to collect data. Fasting live weight was greater (P < 0.05) in lambs fed the SH diets than in those fed the CON diet. Hot and cold carcass weights were greater in lambs fed 150 g/kg SH compared with CON. Water holding capacity increased (P < 0.05) in the SH150 group, whereas shear force decreased (P < 0.05) in the SH75 group. Sesame hulls feeding decreased (P ≤ 0.01) the concentrations of C12:0, C13:0, C17:0, C18:0, and C21:0, resulting in a lower total saturated fatty acid (SFA) content (P = 0.003) compared with the CON diet. Conversely, the content of C18:1 cis+trans (n-9) and total monounsaturated fatty acids (MUFA) was greater in the SH groups than in the CON group. In summary, sesame hulls are a viable, sustainable alternative feed that can maintain or enhance carcass characteristics and meat quality. Supplementation of SH also improved the fatty acid profile by decreasing SFA and increasing MUFA and n-3 fatty acids.
