Following weaning, both groups were confined until they reached 38.6 kg average weight, and then separated into two types of treatment: Pasture rearing: 5 ewes from artificial suckling + 8 ewes from controlled suckling; Confined rearing: 5 ewes from artificial suckling + 8 ewes from controlled suckling. The experimental design was a 2 × 2 factorial, randomized. Average daily milk production for artificial suckling (0.318 kg) was higher than controlled suckling (0.256 kg). The economic return of the controlled suckling treatment was 8.13% higher than for artificial suckling. With regard to the pasture rearing and confined rearing treatment systems, there was no estrus for pasture rearing during experimental period. There was no difference between the weaning systems with regard to eggs per gram. The weaning system influenced the milk production of primiparous females.317-321porEconomic analysisEwe-lambsMilk productionWeight gainOvis ariesDesempenho de cordeiras Bergamácia submetidas a dois sistemas de desmamaPerfomance of female Bergamasca lambs submitted to two artificial weaning systemsArtigo10.4025/actascianimsci.v32i3.7359Acesso aberto2-s2.0-779569447662-s2.0-77956944766.pdf2568037997042860
