Description
Maria Cláudia Soares Cruz Coelho and a team of co-authors tested whether Pornunça hay can replace Tifton 85 hay as the roughage in feedlot lamb diets. Thirty-six young Santa Inês male lambs spent 71 days in confinement while the share of Pornunça in the roughage rose across four groups, from none to complete replacement.
Lambs on the Pornunça diets ate more dry matter and organic matter, though they digested protein and fiber less well. Final weight, daily gain, and feed conversion stayed the same across groups, while hot and cold carcass weights and yields rose as Pornunça increased. Meat color, tenderness, water holding, and basic composition did not change. On that basis the authors recommend swapping Tifton 85 hay fully for Pornunça hay for feedlot lambs.
