RESUMO:

The objective of this study was to evaluate nutrient intake, apparent digestibility of dry matter and nutrients, animal performance and ingestive behavior of sheep of the genetic group Soinga and crossbreed fed with small palm (Nopalea cochenillifera) and Mexican Elephant Ear (Opuntia stricta), besides elephant grass silage, corn and soybean efflorescence in the diet of confined lambs. Twenty-eight animals with an average weight of 17.9 kg ± 1.58 kg were used, 14 Soingas and 14 crossbreed were individually distributed in a completely randomized design in a 2x2 factorial scheme. 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, considering the daily consumption of the diets and the weight of each animal every 14 days, 5 days of which were destined for fecal collection for the apparent digestibility assay. Ingestion of DM, OM, OMD, CP, NDF, EE, 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, 0.030, 0.557 and 0.732, respectively ). Dry matter and nutrient intakes and feed conversion were not different among genotypes (p> 0.05). However, there was interaction between palm species and genetic grouping for the consumption of neutral detergent fiber. The total digestibility of DM, OM, CP, EE and NFC was higher when the animals consumed the Mexican Elephant Ear palm (p<0.05), there was no interaction between the palm species studied and the genetic groups studied for digestibility of nutrients. There was no interaction between the studied palm species and the genetic groups for the daily average weight gain of 0.132 kg/day, being 0.123 kg/day for the Soinga sheep and 0.142 kg/day for the crossbreed. There was interaction between the palm species and the genetic grouping for the behavioral variables leisure time and feeding time. It is recommended that the Mexican Elephant Ear palm can be used in feedlot feed for lambs, and it was concluded that the Soinga and crossbreed genetic group presented similar animal performance.
