Santa In?s x ? Soinga) alimentados com gen?tipos de palma forrageira resistentes ? cochonilla do carmim (Mi?da e Orelha de Elefante Mexicana). Foram utilizados 28 ovinos, sendo 14 Soingas e 14 ? Santa In?s x ? Soinga com peso m?dio inicial de 17,4 ? 1,58 kg, distribu?dos aleatoriamente em delineamento inteiramente casualizado em esquema fatorial 2x2. Os animais permaneceram confinados por 102 dias, sendo os 30 primeiros para adapta??o dos animais ?s instala??es e manejo experimental, os 72 dias restantes destinados ? coleta de dados e amostras. N?o houve intera??o significativa entre esp?cies de palma e grupamentos gen?ticos para o consumo de mat?ria seca e nutrientes. A ingest?o de MS, MO, MOD, PB, FDN, CNF e NDT em kg/dia n?o foi afetada pelas dietas experimentais (1,009; 0,910; 0,686; 0,139; 0,298; 0,557 e 0,732, respectivamente). O consumo de mat?ria seca e nutrientes e a convers?o alimentar n?o foram diferentes entre os grupamentos gen?ticos. Os coeficientes da digestibilidade da MS, MO, PB e CNF foram maiores quando os animais consumiam a palma Orelha de Elefante Mexicana, n?o houve intera??o entre as esp?cies de palma e os grupamentos gen?ticos estudados para a digestibilidade aparente dos nutrientes. N?o houve intera??o entre as esp?cies de palma e os grupamentos gen?ticos para as vari?veis comportamentais estudadas. N?o foram verificados efeitos das palmas, grupamentos gen?ticos e intera??o entre ambos para o ganho de peso m?dio di?rio, que apresentou m?dia de 0,133 kg/dia. A digestibilidade da palma Orelha de Elefante Mexicana apresentou superioridade ? palma mi?da. Os grupamentos gen?ticos Soinga e ? Santa In?s x ? Soinga apresentaram desempenho semelhantes quando alimentados com as diferentes esp?cies de palma, podendo a palma Mi?da e Orelha de Elefante Mexicana ser utilizadas na dieta para cordeiros em confinamento. / The objective of this study was to evaluate the intake and apparent digestibility of the dry matter and nutrients, the ingestive behavior and the performance of sheep of two genetic groups (Soinga and ? Santa In?s x ? Soinga) fed with forage palm genotypes resistant to Cochineal carmine (Mi?da and Mexican Elephant Ear). Twenty - eight sheep were used, 14 Soingas and 14 ? Santa In?s x ? Soinga with initial mean weight of 17.4 ? 1.58 kg, randomly distributed in a completely randomized design in a 2x2 factorial design. The study lasted 102 days, with the first 30 days for adaptation of the animals to the facilities, diet and routine management, and 72 days of observation and collection for performance evaluation. There was no significant interaction between cactus species and genetic groups for the consumption of dry matter and nutrients. Ingestion of DM, OM, OMD, CP, NDF, CNF and TDN by dietary components in kg/day was not affected by experimental diets (1.009, 0.910, 0.666, 0.139, 0.298, 0.557 and 0.732, respectively). The intake of dry matter and nutrients and feed conversion were not different between the genetic groups. The total digestibility of DM, OM, CP and NFC was higher when the animals consumed the Mexican Elephant Ear cactus, there was no interaction for nutrients digestibility between the cactus species and the genetic groups. There was no interaction between the cactus species and the genetic groups for the behavioral variables studied. There was no interaction between the studied cactus species and the genetic groups for the average daily weight gain, 0.133 kg/day. The digestibility of the Mexican Elephant Ear was higher than Mi?da. The genetic groups Soinga and ? Santa In?s x ? Soinga had similar performance when fed with the different cactus species, and the Nopalea cochenillifera and the Opuntia stricta can be used in the diet for lambs in confinement.
