FORAGE CACTUS ASSOCIATED WITH CUT ELEPHANT GRASS HAY AT DIFFERENT AGES IN SHEEP FEEDING
Forage cactus; Elephant grass; Nutrient intake; digestibility; semiarid.
The objective was to evaluate the intake and apparent digestibility of different nutrients, the ingestive behavior and performance of animals in sheep receiving diets containing cactus pear with elephant grass hay at different regrowth ages (60, 120, 180 and 240 days). Sixteen Santa Inês sheep with an average weight of 25 kg were used, housed in individual pens, divided into four treatments: T1: EC hay cut at 60 days + cactus pear + Concentrate, T2: EC hay cut at 120 days + Forage palm + Concentrate, T3: EC hay cut at 180 days + Forage palm + Concentrate and T4: EC hay cut at 240 days + Forage palm + Concentrate. The experiment lasted 45 days, with 15 days of adaptation of the animals to the diets and management and 30 days of data and sample collection (food, leftovers and feces). The consumption of dry matter, organic matter and neutral detergent fiber decreased linearly with increasing cutting age of elephant grass. The digestibility had a linear increase for the apparent coefficients of dry matter and organic matter with the increase in elephant grass cutting age. With this, elephant grass at advanced ages can guarantee similar performances when used in the feeding of growing sheep associated with cactus pear, which can guarantee producers better animal performance in the dry season.
