Nutritional value, feeding behavior, physiological parameters, and performance of crossbred Boer goat kids fed butterfly pea hay and cactus pear meal

Aim of study: To evaluate diets with different proportions butterfly pea hay (BH) and cactus pear meal (CM) on the intake digestibility nutrients, productive performance, feeding behavior physiological parameters crossbred Boer kids.
 Area Northwest Brazil.
 Material methods: 32 intact male goats were distributed in a randomized block design, four treatments BH CM diets, partially replacing elephant grass total dry matter (DM) basis: 0% + 0 % as control, 83% 17% CM, 67% 33% 50% CM. Each treatment group included eight animals. The experiment lasted 84 days preceded by 15 adaptation.
 Main results: Kids fed control diet had greatest neutral detergent fiber, hemicellulose, water via food, time to feed lowest conversion (p<0.05) compared BH+CM diets. Diet BH+17% provided less greater efficiency DM lower fiber rumination other BH+33% resulted organic matter, weight gains longer chewing (seconds/cud) BH+50% showed acid for rumination, ingestion rectal temperature, idle times diets.
 Research highlights: Partial substitution increased gain kids, without changing nutrient finishing.
