CACTÁCEAS NATIVAS ASSOCIADAS A FENOS DE FLOR DE SEDA E SABIÁ NA ALIMENTAÇÃO DE CABRAS LEITEIRAS

Abstract

The objective of this study was to evaluate the utilization effects of two native cacti named mandacaru (Cereus jamacaru DC.) and xiquexique [Pilosocereus gounellei (A. Weber ex K. Schum.) Bly ex Rowl.] associated with sabiá (Mimosa caesalpinifolia Benth.) and flor de seda (Calotropis procera (Ait.) R.Br.) shrub hays on nutrient intake, milk production and composition of Saanen dairy goats¿. Eight goats averaging 43.4 kg were used in two 4x4 latin square experimental design. The experimental treatments consisted of four diets (30% native cacti + 30% shrub hay + 40% concentrate, on dry matter basis): xiquexique + flor de seda hay; xiquexique + sabiá hay; mandacaru + flor de seda hay and mandacaru + sabiá hay. The ingredients proportion of the concentrate in the diet was 57.5% algaroba (Prosopis juliflora (Sw) DC); 37.5% soybean meal and 5% mineral mixture. Significant differences were observed for voluntary intakes of dry matter, organic matter, ether extract, neutral detergent fiber, acidy detergent fiber, total carbohydrates, nonfiber carbohydrates and total digestible nutrients in relation to g/day and g/kg0.75. No significant differences were observed for milk production (averaged 1,294.39 g/day), and milk composition.
