Resumo: A viable alternative to feed animals in dry seasons is the use of regional foods, such a agroindustrial by products, which are generally low-cost, easy to acquire and transport. However, the lack of knowledge about the chemical composition and nutritive value of these by-products is a challenge in the research area of ruminant production and nutrition. Two experiments were carried out. In the experiment I, we aimed to characterize the sweet apple (Annona squamosa), sour soup (Annona muricata) and passion fruit seeds (Passiflora edulis). Four samples of the crushed were collected at the Biodiesel Plant located in the municipality of Caetés-PE and were sent to the Animal Nutrition Laboratory (LANA) of the Federal Rural University of Pernambuco, Garanhuns Academic Unit (UFRPE / UAG). The dry matter (DM), mineral matter (MM), organic matter (OM), neutral detergent fiber (NDF), acid detergent fiber (ADF), crude protein (CP), acid detergent lignin (LDA) ethereal extract (EE), true in vitro digestibility (IVD), and total digestible nutrients (NDT) and cellulose (CEL) values were estimated. Fractionation of carbohydrates and proteins was performed based on the Cornell Net Carbohydrate and Protein System (CNCPS). For the amount of total carbohydrates, the passion fruit seed crushed stood out (75%), but the fraction C (86% of the total carbohydrates) was more evident in the same, contrary to the pecan seed crushed that presented lower concentration of Total carbohydrates (59%), but with the A + B1 fraction (13%) more evident. Regarding the fractionation of nitrogen compounds, higher levels of fraction A were observed in the sweet apple seed crushed (20%). Among the evaluated crushed, sweet apple seed crushed (57.6%) was highlighted with greater intensity of ruminal degradation, followed by sour soup seed crushed (49.2%). True digestibility was also higher for sweet apple seed crushed (51.7%) and lower for passion fruit seed crushed (27.1%). The highest volume of gases produced was observed in sweet apple and sour soup (133.3 mL / g MS, 115.8 mL / g MS respectively). In the experiment II the objective was to evaluate the inclusion of sour soup seed crushed (Annona muricata) at increasing levels (5, 10, 15 and 20%) in complete diets for sheep with 20kg and daily gain of 200g. The ingredients used were Typhton hay, milled corn, small palm, soybean meal, urea and mineral mix. There was a significant influence (P<0.05) in the experimental diets, showing a linear decreasing effect on the inclusion levels of sour soup seed on the means of IVDMD and on in vitro degradability parameters, as well as on the total volume of Gases produced. The total gas production (Vt1), as well as the volume of the production of gases from the degradation of non-fibrous (Vf1) and fibrous carbohydrate fractions (Vf2) and their respective degradation rates decreased linearly (P<0.05) as they increased The levels of pie in the diet. The lag time had no significant influence (P>0.05). The pH of the diets did not change during the incubation period as well as the concentrations of ammoniacal nitrogen. The search for alternative food for animal production is one of the most promising areas of research in animal nutrition and the results of this research confirm the potential use of these co-products from the biodiesel industry and show that the integration of agriculture and livestock is important. Thus, it is suggested to carry out further studies demonstrating the importance and characterizing these residues of the biodiesel chain as an alternative food for production animals.
