Maintenance and Growth Requirements in Male Dorper × Santa Ines Lambs [PDF]
Frontiers in Veterinary Science, 2021 The aim of this study was to estimate the energy and protein requirements for maintenance and growth of lambs. A total of 35 crossbreed Dorper × Santa Ines lambs [31 ± 1.28 kg of initial body weight (BW) and 4 months old] were distributed in a completely randomized design with three treatments groups (ad libitum, 30 and 60% of feed restriction).
