Escherichia coli is a bacteria of the Enterobacteriacea family and it is part of the enterical microflora of mammals and of many species of birds. Salmonella spp. also belongs to the family Enterobacteriacea, it is responsible for human feed toxinfection outbreaks and usually isolated from domestic and wild birds. The present study analyzed the frequency of both agents in Psittaciformes in rehabilitation process for wildlife reintroduction. In 89 birds analyzed, 19% were infected with E. coli and 1,12% with Salmonella spp. It was carried out an analysis of the profile of antibiotic resistance in which was observed the efficiency of estreptomicin, tetraciclin, trimetoprim and gentamicin over the samples. The samples of E. coli were submitted to the Congo Red Binding test and to the Hemolisis test and 70,6% of positive samples for the first test and 53% for the second one were observed.

Objeti vo: Avaliar os efeitos da expansão lenta na maxila e na mandíbula com o aparelho ortodônti co removível superior com torno de expansão simétrico e mediano, nas regiões oclusal, gengival e alveolar de pacientes jovens com atresia maxilar. Método: A amostra compreendeu 18 indivíduos leucodermas (11 meninas e 7 meninos; idade média: 8 anos e 10 meses no início do tratamento) que apresentavam atresia da maxila, acompanhadas ou não de mordida cruzada posterior uni ou bilateral na fase de denti ção mista. Todos os pacientes foram tratados com aparelho ortodônti co removível superior com torno de expansão simétrico e mediano, sendo o tempo médio de tratamento de 15,4 meses (± 7,6). Para avaliar a infl uência do tratamento nas mensurações dos pontos demarcados nas regiões oclusal, gengival e alveolar, foram uti lizados os modelos de gesso dos arcos superior e inferior (36 pares) obti dos em dois tempos: T1: início do tratamento e T2: ao fi nal do tratamento. Para cada paciente em ambos os tempos, foram mensuradas as distâncias transversas na região oclusal entre caninos decíduos, 1o molares decíduos ou 1o pré-molares permanentes e entre 1o molares permanentes, superiores e inferiores. Para verifi car se a movimentação ocorreu por inclinação ou por movimento de corpo, foram uti lizadas também medidas nas regiões gengival e alveolar. Os dados foram avaliados estati sti camente pelo teste “t student para amostras pareadas (5%). Resultados: Observou-se que em T2, todas as distâncias mensuradas para as regiões oclusal, gengival e alveolar apresentaram valores estati sti camente superiores às mesmas medidas em T1 (p<0,05). Conclusão: O aparelho ortodônti co removível superior é efeti vo nos casos de expansão lenta da maxila, agindo também indiretamente nas dimensões transversas do arco inferior.

Were used 64 weaned pigs, distributed in eight treatments: ration with skim milk (SM), three rations with crescent levels of swine plasma (SP), three rations with whole egg (WE) and a ration with high inclusion of soybean meal (SB). Daily weight gain (DWG), daily feed intake (DFI) and feed conversion (FC) were evaluated. The animals that consumed ration SB have the mean of DWG higher that other treatments, and inferior FC, from 35 to 48 days of age. The crescent levels of SP promoted linear reduction in DWG, from 21 to 35, and from 35 to 48 days of age, in DFI from 48 to 138 days of age and linear increased in FC from 21 to 35 of age. Considering the weaned phase until finishing, initial rations can be formulated with SP and WE substituted partially the CP of skim milk in 25 and 45%, respectively.

The objective of this study was to assess the performance, tonic immobility time (TIT), intensity of injuries (II) and heterophil to lymphocyte ratio (H:L) by the addition of the symbiotic and plant extract (Aloe vera and Symphytum officinale) to the diet of Japanese quails. Ninety quails were used, distributed in randomized blocks with 3 treatments (0-control; 250 and 750 mg symbiotic and plant extract/kg of diet), five repetitions and six birds per cage. Feed intake, feed conversion, production and weight of eggs, viability, TIT, II and H:L were evaluated. Results showed that the addition of the product to the diet did not affect the performance, however, it decreased the TIT, II and the H:L of quails which received the highest level of the product in the diet. Thus, the use of symbiotic and plant extract in the diet has been promising regarding the behavioral and physiological parameters, decreasing the stress of the animals, mainly for the level of 750 mg/kg diet.

Two assays were conducted to determine the coefficients of digestibility (CD) and the digestible nutrients (DN) of the extruded semi-whole soybean (Assay 1 conventional feeding and Assay 2 feeding for sows, starting at 109 days of pregnancy and during the lactation and for lactating piglets and in the initial phase, with rations without soybean meal). Each assay was divided into two phases (32 and 50 days of age). Eight piglets weaned at 25 days of age were used. Total feces collection method was used. The following variables were analyzed in feed and in feces: dry matter, crude protein, ether extract, crude fiber and gross energy. The following average values were obtained: CDDM 88.87%; CDCP 86.81%; CDEE 85.41%; CDCF 78.22%; CDGE 80.21% and CMDE 95.71%, which allowed the calculation of the digestible nutrients: DDM 81.28%; DP 34.49%; DEE 14.02%; DF 4.49%; DEa 4087.86 kcal/kg and MEa 3912.73 kcal/kg. The different coefficients of digestibility were not affected by the differential feeding for sows and piglets nor by the different ages of the animals. Moreover, the extruded semi-whole soybean presented good levels of DN, concerning mainly the digestible and metabolizable energy.
