O uso de ducha: efeito sobre o bem-estar e a qualidade da carcaça e da carne em suínos transportados para o abate

This study was carried out to evaluate the effects of a shower before and after pig transportation on welfare, meat and carcass quality. We used 384 crossbreeding animals (females and castrated males), from 16 farms in Santa Catarina State, Brazil. A 2x4 factorial arrangement of treatments was employed with two distances from farm to slaughter plant (less than 50km and more than 50km) and four showering protocols. These protocols were applied on pigs: no showering at farm or slaughter plant (Control), no showering at farm but showering at the plant (NMG_MOF); showering at the farm and no showering at the plant (MOG_NMF); showering at the farm and plant (MOG_MOF). None of the factors influenced (P>0.05) physiological variables related to stress (cortisol and lactate in blood samples), number of carcass lesions and the characteristics of meat quality.

Características morfométricas e rendimento corporal do suruvi Steindachneridion scriptum agrupados por sexo

The body shape, body yields and morphometric ratios is important for species characterization and evaluation of their productive potential. The aim of this study was to determine the morphometric reasons, the body yields and correlations for male and female suruvi, Steindachneridion scriptum. Was analyzed 30 males and 30 females, and length and weight measurements were made. Was calculated carcass yields and morphometric relationships. The design was complete randomized. Data were subjected to analysis of normality; variance and means were compared by t test and Mann Whitney test. The average total weight of males was 1,583.50 +/- 263.79 g, while the total weight of females was 1,606.66 +/- 185.34 g. The total lengths were 53.42 +/- 2.64 cm for males and 53.35 +/- 1.98 cm for females. Average total weight and total lengths was similar between the sexes (P>0.05). Dress out yields of 65.54 +/- 1.36% (males) and 65.71 +/- 1.20% (females) and edible portions of 41.99 +/- 1.66% (males) and 41.93 +/- 2.05% (females) did not differ significantly between the sexes (P>0.05). The percentage of head relative to the total weight was significantly higher in males (17.67 +/- 1.24%) than in females (16.90 +/- 0.85%). The weight of the viscera such as the percentage relative to the total weight was significantly higher in females. The species has no body yields and morphometric characteristics limitations for commercial production.

Efeito do sistema de produção nas características físico-químicas e no perfil lipídico de três músculos de suínos alentejanos

O presente trabalho tem como objetivo testar o efeito do sistema de produção com dieta rica em ácido oleico nas características zootécnicas, de carcaça, físico-químicas e no perfil lipídico dos músculos Longissimus dorsi (LD), Biceps femoris (BF) e Semimembranosus (SM) de suínos de raça Alentejana. Foram utilizados 15 animais, divididos em dois grupos, o grupo IN (n=9) foi mantido em parques individuais abertos ao exterior com 3 m2 e o grupo OUT (n=6) foi mantido numa área de 3 ha com acesso a pastagem. O grupo OUT obteve melhores performances zootécnicas. O rendimento de carcaça foi igual para ambos os grupos, e o rendimento comercial e proporção de peças nobres foi superior nos OUT. Estes obtiveram menores teores de lípidos intramusculares mas maiores teores de PUFA (ácidos gordos polinsaturados) e melhores valores para os rácios PUFA/SFA (ácido gordos saturados) e n-6/n-3. O SM foi menos afetado pelo sistema de produção; Abstract: Effect of the rearing system in the physical-chemical characteristics and the lipid profile of three muscles from Alentejano pigs The present study aims to test the effect of rearing system with oleic acid rich diet on performance, carcass and physical-chemical characteristics, and lipid profile of the muscles Longissimus dorsi (LD), Biceps femoris (BF) and Semimembranosus (SM) from Alentejano pigs. The study used 15 animals, divided into two groups. The Group IN (n = 9) was kept in individual parks open to the exterior with 3 m2, and the OUT (n = 6) was held in an area of 3 ha with access to pasture. The OUT group obtained the best performances. The carcass yield was the same for both groups, meat yield and the proportion of noble parts was superior in the OUT. These obtained lower levels of intramuscular fat but larger PUFA levels (polyunsaturated fatty acids) and best values for the ratios PUFA/SFA (saturated fatty acids) and n-6/n-3. The SM was the least affected by the rearing system

Ressonância magnética e características clínicas em adultos com doenças desmielinizantes monofásicas: encefalomielite aguda disseminada ou uma variante da esclerose múltipla?

Acute disseminated encephalomyelitis (ADEM) is a widespread monophasic inflamatory disease affecting the central nervous system, that usually follows an infection or vaccination. In this study, we present an analysis of magnetic resonance imaging (MRI), cerebrospinal fluid (CSF) and clinical aspects in four patients with clinical diagnosis of ADEM. The presence of MRI demyelinating lesions was crucial, but not in itself sufficient for definitive diagnosis. Clinical and MRI follow up, in order to exclude new lesions and to reevaluate the former ones, as well as CSF, were important for the differential diagnosis with other demyelinating diseases, particularly multiple sclerosis. In addition, we have shown that early treatment with methylprednisolone after the initial symptoms was effective for improving clinical manifestations as well as for reducing MRI lesions.

Levantamento e características ecológicas de orchidacea e da mata ciliar do rio dourados, Dourados-MS

The Orchidaceae is one of the largest flowering plants family and with a great importance to conservation. However, no survey on orchid flowers can be found in Mato Grosso do Sul. Thus, the objective of this work was to make a survey of the Orchidaceae species and of its ecology features in a riparian forest in a fragment of Floresta Estacional Semi-Decidual that belongs to the riparian forest of the Dourados River. The inventory was made by using a sweeping method for collection, and in addition to this the vertical and horizontal position of epiphytes were assessed on the hosts. For characterization of microclimate, it was used a thermohygrometer and luximeter. It was identified 17 species of 13 genera. Of the listed genera, the most abundant ones were: Acianthera, Macradenia and Capanemia. It was also noted a vertical and horizontal distribution of the Orchidaceae in relation to inverse gradient of water and light availability. Some species tended to be sensitive to height level categorization, whereas others seemed to occur with similar frequency along the host. In relation to the cardinal orientation, the apparent preferential response for south and east directions was associated to the low sampling effort and lower water availability, which could occur because the north face is opposed to the water body.

Características físicas e mecânicas de misturas de solo, cimento e cinzas de bagaço de cana-de-açúcar

This work was done with the objective of studying some physical and mechanical characteristics of the sugarcane bagasse ash added to a soil-cement mixture, in order to obtain an alternative construction material. The sugarcane bagasse ash pre-treatment included both sieving and grinding, before mixing with soil and cement. Different proportions of cement-ash were tested by determining its standard consistence and its compressive resistance at 7 and 28 days age. The various treatments were subsequently applied to the specimens molded with different soil-cement-ash mixtures which in turns were submitted to compaction, unconfined compression and water absorption laboratory tests. The results showed that it is possible to replace up to 20% of Portland cement by sugarcane bagasse ash without any damage to the mixture's compressive strength.
