In extensive sheep production systems -based primarily on native pastures (NP)-, summer forage production is mainly explained by rainfall and it presents a high variability among years. Additionally, in summer just after weaning, dry matter digestibility, metabolizable energy and crude protein (CP) content of NP are insufficient to meet the requirements of lambs so as to achieve their potential body and wool growth. The strategic use of supplements is key to improving productivity. In a completely randomized experimental design with two replications, the impact of iso-energetic supplements with different protein levels on body and wool growth was studied in eighty crossbreed (Merino Dohne × Corriedale) castrated male lambs (24.5 ± 4.4 kg of body weight, BW, 4 months of age) in summer (103 days) for three years. Animals were randomly allotted to four treatments (n=20). All lambs grazed NP and in three treatments animals were daily supplemented (2% BW) with an iso-energetic supplement of different CP levels: control (CON, no supplement), 12% CP (12CP), 16% CP (16CP) and 20% CP (20CP). Supplemented lambs presented higher final BW (36.0, 36.4 and 37.7 kg for 12, 16 and 20CP, respectively) than CON lambs (28.9 kg) (P<0.05). Among supplemented lambs, the 12CP group had the lowest BW (P<0.05), without differences between 16CP and 20CP. Supplemented lambs presented greater average daily gain, body condition score, rib eye area and fat thickness than CON lambs (P<0.05). Wool growth was 40% higher in supplemented lambs compared to CON lambs (P<0.05), while 20CP animals presented the greatest growth. Iso-energetic supplementation with different CP (12, 16 and 20%) content improved body and wool growth of lambs grazing NP compared to non-supplemented lambs in summer after weaning. Body and wool growth were greatest when 20% CP supplement was used.
