Abstract: Três experimentos, um ensaio de digestibilidade, avalia o morfométrica intestinal e desempenho, foram conduzidos para avaliar os efeitos da adi o às dietas, do Calsporin (0,03%), do ácido fumárico (1,5%) e da bacitracina de zinco com 15% de atividade (0,10%), em separado ou em combina es, sobre a utiliza o da matéria seca, proteína bruta, fibra em detergente neutro e energia bruta, a análise morfométrica do jejuno e o desempenho de coelhos em crescimento. No ensaio de digestibilidade, 64 coelhos da ra a Nova Zelandia Branco, metade de cada sexo, com 50 dias de idade, foram distribuídos em um delineamento inteiramente casualizado, com oito tratamentos e oito repeti es. A adi o de qualquer dos aditivos, em separado ou combinados, às dietas de coelhos n o influenciou a utiliza o da matéria seca, matéria organica, proteína bruta, fibra em detergente neutro e energia bruta. Para a análise morfométrica do jejuno, foram abatidos 100 coelhos da ra a Nova Zelandia Branco, sendo quatro no início do experimento, aos 35 dias de idade e, em seguida, quatro animais por tratamento, aos 50, 60 e 75 dias de idade. A inclus o de qualquer aditivo às dietas, em separado ou combinados, n o demonstrou efeito sobre a espessura da túnica mucosa, da túnica muscular externa e da parede total do jejuno de coelhos em qualquer das idades estudadas. Contudo, a espessura da túnica mucosa diminuiu linearmente com a idade.Para o ensaio de crescimento, foram utilizados 176 coelhos da ra a Nova Zelandia Branco, metade de cada sexo, no período de 35 a 75 dias de idade, distribuídos em um delineamento inteiramente casualizado, com oito tratamentos, 11 repeti es e dois animais por unidade experimental. N o houve efeito da adi o de qualquer dos aditivos, em separado ou em combina es sobre o desempenho no período de 35 aos 50 dias de idade. Para o período total do experimento, o melhor desempenho foi obtido com os animais recebendo dietas com inclus o de ácido fumárico, ácido fumárico + bacitracina de zinco e com a dieta contendo os três aditivos. Tanto o peso, como o rendimento de carca a, foram maiores para os animais alimentados com as dietas, contendo ácido fumárico ou ácido fumárico + bacitracina de zinco. N o houve efeito dos tratamentos sobre o peso do fígado, rins e cora o.

Abstract: The morphology of the stomach may vary between species as a function of feeding habits, differences on the cellular composition of the mucosa of the stomach wall and the different functions it carries out. Morphofunctional variations of the stomach of several animals along phylogeny led us to investigate the morphology of the wall of the glandular stomach of rabbits. We used the stomachs of 32 young rabbits (Oryctolagus cuniculus) from the White New Zealand strain, coming from the Experimental Farm of Iguatemi, owned by the State University of Maringá, Brazil. The stomachs were collected and fixed in Bouin solution; sections of 7 and 12 μm were made from the greater to the lesser gastric curvatures, and subjected to histological routine, for staining with either Hematoxilin-Eosin, P.A.S. or Azan. Next the sections were analyzed under microscope and photographed. Differences in the stratigraphy of the gastric wall were observed when the sections from the greater gastric curvature of the glandular stomach of rabbits were compared with those from the lesser curvature. We verified that the wall of the glandular stomach of rabbits shows differences on the morphology of the mucosa, submucosa, muscle and serosa layers, so that the wall is not uniform around the stomach circumference La morfología del estómago puede variar de una especie a otra, en función de sus hábitos alimenticios, constitución celular de la mucosa de la pared estomacal y de las funciones realizadas por las células constituyentes. Variaciones morfofuncionales del estómago existentes entre los animales de la escala filogenética, nos llevaron a investigar la morfología de la pared del estómago glandular de los conejos. Utilizamos estómagos de 32 conejos (Oryctolagus cuniculus), jóvenes, raza Neozelandés Blanco, provenientes de la Estancia Experimental de Iguatemí, de la Universidad Estadual de Maringá, Brasil. Los estómagos fueron recolectados y conservados en solución de Bouin; se les practicaron cortes de 5 y 12 μm, alcanzando la región que va desde la curvatura gástrica mayor hasta la curvatura gástrica menor, verificación histológica de rutina y coloración con Hematoxilina-Eosina, P.A.S. y Azan. Se observaron las muestras a través del microscopio óptico y luego fueron fotografiados. Observamos diferencias de estratisgrafía en la pared del estómago al comparar los cortes practicados en las curvaturas gástricas mayor y menor del estómago glandular de los conejos. Verificamos que la pared de la región glandular del estómago de los conejos presenta diferencias con relación a la morfología de l

Abstract: Dois experimentos foram conduzidos com o objetivo de avaliar a utiliza o da farinha de varredura de mandioca (FVM), variedade fibra, para coelhos em crescimento. No ensaio de digestibilidade, foram utilizados 22 coelhos com 50 dias de idade, distribuídos em umdelineamento inteiramente casualizado com dois tratamentos e 11 repeti es. Foram utilizadas duas ra es, uma referência e um teste, na qual a FVM substituiu 25% da matéria seca da ra o referência. Os teores digestíveis de matéria seca, proteína, FDN, FDA, energia e amido, com base na matéria seca, foram respectivamente de 85,87%, 1,43%, 2,82%, 0,91%, 3.562 kcal/kg e 63,95%. No experimento de desempenho, foram utilizados 180 coelhos de 35 a 70 dias de idade.Os coelhos foram distribuídos em um delineamento inteiramente casualizado com seis tratamentos (seis níveis de inclus o da FVM: 0%, 20%, 40%, 60%, 80% e 100%, em substitui o à energia digestível do milho) e 15 repeti es com dois animais por unidade experimental. Os resultados permitiram concluir que a FVM pode ser incorporada às ra es de coelhos em crescimento em 26,4%, substituindo 100% a energia digestível do milho. The study aimed to evaluate the effect of cassava root meal on the growth of rabbits. Two experiments were carried out. Digestibilityassay was conducted using 22 rabbits with 50 days of age, in a randomized design, with two treatments and 11 replications. Reference and test diets were used in which CM substituted 25% of the control diet dry matter. The digestible dry matter values, protein, neutral detergent fiber (NDF), acid detergent fiber (ADF), energy and starch, on dry matter basis, were 85.87%, 1.43%, 2.82%, 0.91%, 3,562 kcal/kg and 63.95%, respectively. In the performance trial, 180 rabbits of35 to 70 days of age were used. The rabbits were distributed in a completely randomized design, with six treatments (six levels of CM inclusion: 0, 20, 40, 60, 80 and 100%, replacing the corn digestible energy) and 15 replications, with two animals per experimental unit. Results show that the CM can be incorporated in the growing rabbits rations in 26.4%, replacing 100% of the corn digestible energy.

Os teores digestíveis de matéria seca, proteína, FDN, FDA, energia e amido com base na matéria seca foram, respectivamente, de 52,30%, 3,28%, 9,46%, 4,79%, 2.288 kcal/kg e 23,19%. No experimento de desempenho, foram utilizados 180 coelhos de 35 a 70 dias de idade. Os coelhos foram distribuídos em delineamento inteiramente casualizado, com seis tratamentos (seis níveis de inclus o da CMD: 0%, 20%, 40%, 60%, 80% e 100%, em substitui o à energia digestível do farelo de trigo) e 15 repeti es, com dois animais por unidade experimental. Os resultados permitiram concluir que a CMD pode ser incorporada às ra es de coelhos em crescimento em até 24,30%, substituindo em 100% aenergia digestível do farelo de trigo. Two experiments were carried out to determine the performance of rabbits fed on diets including cassava hulls dried (CHD), fibervariety for growing rabbits. In the digestibility assay, 22 rabbits at 50 days of age were used in a randomized design with two treatments and 11 replicates. Reference and test diets were usedin which CHD substituted 25% of dry matter of control diet. The digestible values of the dry matter, protein, neutral detergent fiber (NDF), acid detergent fiber (ADF), energy and starch, on dry matter basis, contained respectively 52.30%, 3.28%, 9.46%, 4.79%, 2,288 kcal/kg and 23.19%. In the performance trial, 180 rabbits from 35 to 70 days of age were used. The rabbits were distributed in a completely randomized design, with six treatments (six levels ofCHD inclusion: 0, 20, 40, 60, 80 and 100%, replacing the wheat meal digestible energy) and 15 replicates with two animals per experimental unit. The results showed that the CHD can be incorporated in the growing rabbits’ rations in up to 24.30%, substituting 100% of wheat meal digestible energy.

OPSIS : Revista do Departamento de História e Ciências Sociais , 2011,
Abstract: The intension of this article is to think about how Middle Age’s end Portuguese chroniclers rebuilt wars that Portuguese kings did in two different moments namely the continental war against Moors and Christians, and the war overseas, held in the North of Africa. We want to develop by this way how the religion question is present in the wars of those two different contexts. / A proposta desse artigo é pensar como os cronistas do final do medievo português reconstruíram as guerras empreendidas pelos reis portugueses em dois contextos diferentes, a saber, a guerra peninsular, contra mouros e crist os, e a guerra além-mar, realizada no Norte da áfrica. Buscar-se-á desdobrar, assim, como a quest o religiosa se coloca nas guerras nesses dois ambientes.
