Previous issue date: 2010-07-20 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / The maned wolf, Chrysocyon brachyurus, the largest canid of South America, is often characterized as an omnivorous animal because of its diet in the wild, which includes plants and animals. Thus, it is considered a generalist species. Studies about the digestive physiology of this animal are rare, mainly due to the importance of the issue to the support of adequated nutritional manipulation that makes possible the survival of the species. In this sense, the objective of this study is assess the ability of the maned wolf to digest typicals fruits of Cerrado, Solanum lycocarpum (wolf?s fruit) and Annona crassiflora, and characteristics of its diet in the wild as well as examine the digestibility of a mixed diet of rats and quails, representing the animal portion of its diet. The maned wolf has a good ability to digest fruits, reinforcing its characterization as an omnivorous animal, and the fruits are great importance to the processes of nutrition of the species. The study confirmed the enormous importance of wolf?s fruit in the diet of this animal. Besides this, that fruit presented high digestibility by animals tested, and cause of this maned wolf?s fruit is probably very important during the dry period, where the availability of fruits, in general, is lower. The digestibility of dry material of wolf?s fruit is even greater than that of a mixed diet with animal and plant fraction, confirming the importance of that fruit to the nutrition of the maned wolf / O lobo-guar?, Chrysocyon brachyurus, maior can?deo da Am?rica do Sul, ? freq?entemente caracterizado como um animal on?voro devido a sua dieta em vida livre, que inclui itens de origem animal e vegetal, sendo uma esp?cie generalista.
Estudos sobre a fisiologia digestiva desse animal s?o raros, principalmente frente ? import?ncia do tema para o suporte do manejo nutricional adequado que viabilize a sobreviv?ncia da esp?cie. Nesse sentido, o objetivo do presente trabalho ? avaliar a capacidade do lobo-guar? de digerir algumas frutas t?picas do Cerrado, como por exemplo, Solanum lycocarpum (?fruta do lobo?) e Annona crassiflora (?Araticum?), que s?o caracter?sticas da sua dieta em vida livre. An?lise da digestibilidade de uma dieta mista com ratos e codornas que representem a por??o animal da sua alimenta??o.
O lobo-guar? possui boa capacidade de digerir frutos, refor?ando sua caracteriza??o como um animal on?voro, e esses frutos s?o de grande import?ncia para os processos de nutri??o da esp?cie. O estudo confirmou a relev?ncia da ?fruta do lobo?na dieta dos animais, apresentando elevada digestibilidade por parte dos indiv?duos testados, sendo provavelmente muito importante durante o per?odo de seca, onde a disponibilidade de frutos, de forma geral, ? mais baixa.
A digestibilidade da mat?ria seca da ?fruta do lobo? ? ainda maior do que de uma dieta mista com fra??o animal e vegetal, comprovando a import?ncia desse fruto para a nutri??o desses animais.
