    Digestibilidade in situ da indigofera suffruticosa e da varronia leucocephala
    (2019) Oliveira, Pedro Henrique Porfirio; Souza, Evaristo Jorge Oliveira de; http://lattes.cnpq.br/0510969297765295; http://lattes.cnpq.br/6300290493354561
    Objective to evaluate the in situ digestibility of Indigo (Indigofera suffruticos) and kid (Varronia leucocephala). The experiment was conducted in the academic unit of Serra Talhada-UAST of Universidade Federal Rural de Pernambuco-UFRPE in Ruminants. We used three sheep rumen fistulados, no racial pattern set (SPRD) not castrated. We used the random blocks design in schemes of plots subdivided. The plants selected for hatching were subjected to a drying kiln forced circulation of air at 55° c. After the material was ground in a mill with 3 mm sieve and placed in bags of TNT with dimensions of 5 x 10 x 2 cm having 1.0804 grams of sample of Indigo in each bag and 1.0947 grams of sample from the boy hard in each bag , all in duplicate. The rate of dry matter disappearance of Indigo, took 24 hours to reach the peak of disappearance. In relation to the kid hard, took 96 hours to reach the peak of disappearance, taking 72 hours more than the Indigo. In general the anil obtained higher rate of dry matter disappearance (61.20%) than the kid hard (44.40%). Indigo presented significant difference (P < 0.05) when connected the digestibility of potential and effective (2, 5, and 8%/h) compared to the kid hard. The soluble fraction (a), potentially degradable fraction (b), rate of degradation were greater in anil than the kid hard, as the non-degradable fraction (ND), was increased also in the kid hard on Indigo. Despite Indigo be more degradable than the kid hard, both serve as alternative feed for sheep, contributed satisfactorily to production. It is important more research related to chemical composition and disgestibilidade of these foods as much as others, to strengthen the use of fodder plants of the Caatinga in animal production.
