Soluble (a) and potentially degradable (b) fractions and degradation rate of b fraction (c) of dry matter (DM) and crude protein (CP)of Parkia platycephala pods in particle sizes 2 and 5mm were estimated by in situ nylon bag method in sheep. The times of incubation were 3, 6, 12, 24, 48, 72 and 96 hours, and

The aim of this study was to evaluate performance, nutrient digestibility, and carcass quantitative traits of lambs fed diets with and without sunflower seeds and vitamin E. Thirty-two uncastrated lambs at approximately 60 days of age, with 15 ± 0.2 kg, were housed in individual stalls and slaughtered at 32.0 ± 0.2 kg body weight. Treatments consisted of the following four diets: C = sugarcane + concentrate; CS = sugarcane + concentrate with sunflower seeds; CE = sugarcane + concentrate with 1,000 mg vitamin E kg-1 diet dry matter (DM); and CSE = sugarcane + concentrate with sunflower seeds and 1,000 mg vitamin E kg-1 diet DM. The experimental design was completely randomized, in a 2 × 2 factorial arrangement (with and without sunflower seeds and with or without vitamin E, on the diet DM basis), and means were compared by Tukey’s test at 5% significance level. Consumption of vitamin E intake by the lambs provided (P < 0.05) the highest ether extract intake (20.91 g day-1) and consequently the highest (P < 0.05) digestibility of this nutrient (85.34%); however, it reduced (P < 0.05) the intakes of total carbohydrates (394.81 g day-1) and non-fibrous carbohydrates (242.47 g day-1) as a direct consequence of the diet composition. Inclusion of sunflower seeds and vitamin E in the lamb diets did not influence (P > 0.05) carcass morphological or quantitative measurements. Sunflower seeds and vitamin E showed to be satisfactory alternatives for inclusion in the concentrate for feedlot lambs, providing good performance and quality carcasses.

A Rinite Atrófica uma doença infecto-contagiosa do trato respiratório superior, caracteriza-se por ser uma doença de alta prevalência em granjas suinícolas, dando-lhe status de importante enfermidade causadora de prejuízos econômicos devido a sua patogenicidade, por causar perdas na produção e pela dificuldade de ser erradicada dos rebanhos. Este trabalho visou abordar os principais tópicos referentes a essa doença através de uma revisão de literatura. Tais pontos revisados estão relacionados à epidemiologia da doença, patogenia, sinais clínicos, formas de tratamento, bem como, ao controle e profilaxia.Palavras-chave: rinite atrófica, doença infecto-contagiosa, suínos. Abstract:The Atrophic Rhinitis is a contagious infectious disease of the upper respiratory tract. It is characterized by being a high prevalence disease in pig farms, this fact gives to the Atrophic Rhinitis the status of an important disease that cause economic losses due to its pathogenicity, because its causes loss of production and its is hardly eradicated from herds.This article aimed to approach the main topics related to this disease through a literature review. These revised points are related with the disease's epidemiology, pathogenesis, clinical signs, forms of treatment, such as the control and prophylaxis.
