Eight lambs per diet had been previously treated with anthelmintic drugs to remove nematode parasites. Measurements of BW and feed intake, and counts of faecal nematode eggs were made.
Carcass parameters were recorded after slaughter, and tissue components of the hind leg were determined. Longissimus dorsi meat was evaluated for pH, colour, thawing and cooking losses, Warner-Bratzler shear force, chemical composition and sensory properties based on triangle tests.
Relative to ryegrass-fed lambs, sulla-fed lambs had significantly greater dry matter DM and protein intake, a more favourable feed conversion ratio, and superior growth rate, final BW at days of age, carcass weight, yield and fatness. These results were attributed to the high protein and non-structural carbohydrate content of sulla, and also to the moderate CT content of sulla Anthelmintic treatment did not affect lamb growth, as the level of parasitic infection initial and final was low.
The physical, chemical and sensory properties of the lamb meat were not influenced by diet.
