Economia solidária e relações de gênero na agricultura familiar: o caso do grupo produtivo mulheres decididas a vencer

The Women s experiences in the private sphere under the work s field changes the family relationship allowing them more freedom, autonomy and independence. The inequalities, socially built, homemade women s obligations results in discrimination, difficult to insert and recovery on female s job in a job s market, including low salary if compared with men s and difficult to services access in addiction a difficult daily life and in domestic sphere. The women s organisation in productive groups or economically solidary enterprises (ESE) torn possible the social economically organisations and politicians to promote deep changes in a domestically e socially relationship, positioning, for example, women s in publics areas and in the rout of emancipation. The objective of this search are understand men and women relationship in the family agriculture s field starts insert women in economically solidary enterprises (ESE) on Mulunguzinho s settlement (Mossoró/RN). The theoretical framework is inspirited Economical Solidary concept kind division s job and women s empowerment. This search had a qualitative character and exploration through case s study on Mulheres decididas a vencer s group. The secondary information was create through theoretical framework and information collected through semi-structured interviews based in interviews applied for women and yours respective husbands by criterion for women participation on productive activities of beekeeping culture of goat and sheep. This study turns possible conclude that the women s participations in productive groups in solidary economical change significantly their life and their family life. The group s organisations process, the training was received, the collective production, the marketing and the mobilized participation to move it all was fundamental for women share with their families partners some homemade and take care with the children. This finding confirm a different aspect not economical in solidary economy overcoming the monetary value in associative relationship observing principally individuals well-being and the concern with the form of reproduction this way of life in the associated

Influência da alimentação sobre os níveis de retinol do leite caprino

The caprine milk is a product of high biological value and high digestibility. Due to these characteristics it is quite used by newly born children that are not breastfed or that are intolerant to the bovine milk. The vitamin deficiency is a public health problem in underdeveloped areas as the Northeast of Brazil and where areas the caprine ones adapt very well. The present study was led to analyze the influence of the feeding in the vitamin levels in the caprine milk. The animals used were the races Saanen and Murciana, divided in three groups. The first group with 38 animals of race Saanen and the second with 30 animals of race Murciana were, fed with concentrated and voluminous. A third group with 20 animals of the race Saanen was fed exclusively with voluminous. The four group was added with 10. 000 UI of retinol palmitato, administered directly, like capsule, in the mouth of animal. Parallel it was verified the level of retinol of milk in the beginning and final of the sucked, in the goats of the second group (race Murciana n =30). The retinol of caprine milk was determined through the system of liquid cromatografia of high efficiency (HPLC). The retinol levels in the studied groups were respectively: first (38. 5 ± 12. 7 μg/100ml), second (40. 5 ± 9. 7 μg/100ml); third, with 20 animals of race Saanen fed exclusively with voluminous (23. 1 ± 6. 7 μg/100ml) and in the group a, suplementation with 10. 000 UI of retinol palmitato (43,7 ± 18,8 μg/100ml) before, and (61,9 ± 26,9 μg/100ml) after the supplementation. It was not found significant difference between the averages from animals of the first and second group, that were fed with the same concentrate diet and voluminous, showing that the retinol levels in the milk of these two races are equivalent. Already in the animals of the first and third group that they were fed with different diets, in those which diet was just voluminous, a drastic reduction was verified in the retinol levels. In relation to the retinol of the milk in different moments from the same sucked, it was observed in the beginning of the breast-feeding (22. 6 ± 9. 8 μg/100ml) and at the end of the sucked (49. 6 ± 14. 7μg/100ml), being the difference between the averages, statistically significant (p < 0,0001). Already in the animals that were supplemented, a significant increase was observed in the retinol concentration, being obtained a medium response of 41,85%

Flebotomíneos (Diptera: Psychodidae) em um sistema agroflorestal da Região Metropolitana de Natal, Rio Grande do Norte, Brasil

Sandflies stand out as important vectors of leishmaniasis. The females need to ingest blood meals, enabling them to transmit protozoa of the genus Leishmania, which may give rise to visceral leishmaniasis (VL) or American tegumentary leishmaniasis (ATL), in addition to transmitting other parasites. Leishmaniasis are important infirmities, distributed worldwide, whose infection results from the interaction of reservoir animals, the vector insect, parasitic protozoa and the healthy host. In the state of Rio Grande do Norte (RN), Brazil, these insects are important transmitters of VL, which usually presents in the most serious form. It occurs mainly in metropolitan areas, with the dog as its main reservoir and Lutzomyia longipalpis as the vector. ATL is most present in the highland areas of the state. In addition to hematophagia, engaged in by the females, both sexes need to ingest carbohydrates, which are essential to the sand flies energy requirements and may interfere in the development of Leishmania. The aim of this study was to determine the occurrence and abundance of sand flies in different environments on the farm belonging to the Empresa de Pesquisas Agropecuárias do RN (Institute of Agricultural Research of RN), in the municipality of Parnamirim, in order to relate this occurrence with climatological and biological references and eating habits. Three consecutive monthly collections were carried out with CDC traps in a fragment of the Atlantic Forest, in a residence, on a goat breeding farm and on cashew, dwarf and giant coconut, mango, banana, eucalyptus, acacia and bean plantations. A total of 1241 sandflies from eight species (Lutzomyia evandroi, Lutzomyia longipalpis, Lutzomyia shannoni, Lutzomyia sordellii Lutzomyia walkeri, Lutzomyia wellcomei, Lutzomyia whitmani, and Lutzomyia intermedia) were collected, most in the forest environment. L. longipalpis, the main VL transmitter, was confirmed as a species adapted to anthropic environments, whereas others such as L. wellcomei, the vector of ATL, occurred predominantly in forests. Carbohydrate characterization of the sand flies and plants of the region demonstrated that a number of exotic plants such as hay and eucalyptus may play some role in the adaptation of these species to modified environments. Breeding in laboratory showed a mean biological cycle of 53.5 days from egg to adulthood for L. shannoni and the possibility of diapause behavior in L. wellcomei. This study serves as a source of information that may contribute to the epidemiological vigilance of tegumentary and visceral leishmaniasis in the state, given that it analyzes the bioecology of transmitting species, as well as their potential to adapt to new environments

Ocorrência da infecção por Toxoplasma gondii e avaliação da imunização em caprinos do sertão do cabugi, Rio Grande do Norte

Toxoplasmosis is one zoonosis caused by Toxoplasma gondii protozoan. Goats, amongst the production animals, are one of the species most susceptible to this parasite, being one them main involved agents in ovine and goat abortions, determining great economic losses and implications for public health, since the presence it parasite in the products of goat origin, consist in one of the main sources of infection for the man. In this study 244 blood samples in 8 farms situated in 4 cities from the Sertão do Cabugi region, Rio Grande do Norte State, northeast of Brazil and, tested by ELISA assay. The results had shown a prevalence of 47.13% for anti- T. gondii antibodies and a significant association between positivity and variable evaluated as age, locality and property. The IgG avidity assay evaluated in 115 positive samples was carried to discriminate acute and chronic infection. Twelve samples (10.4%) had presented antibodies of low avidity while 103 (89.6%) presented high avidity antibodies; indicating that most of the animals was precocious exposure to the parasite. Significant difference was verified only for the variable sex. We also evaluate the capacity of recombinant adenoviruses codifying SAG1, SAG2, SAG3 and CMV in inducing activation of specific immune response in goat. These 109 animals received 109 pfu of the AdSAG1, AdSAG2, AdSAG3, AdCMV or PBS in vaccine protocol with 3 immunizations. Serum samples of the each animal, before and after mmunization, had been submitted to the ELISA. The results demonstrate that the immunizations had induced the production of IgG antibodies specific against T. gondii proteins

Performance and ruminal morphologic characteristics of Saanen kids fed ground, pelleted or extruded total ration

The aim of the present study was to determine feed intake and average weight gain and to evaluate the ruminal morphologic characteristics of Saanen kids slaughtered at 30, 45 and 60 days of age, according to a completely randomized design. Thirty-six non-castrated male Saanen kids were fed ground total ration, pelleted total ration, or extruded total ration. Feed intake and refusals were controlled daily and the animals were weighed at birth and then once a week. Newborn kids received a milk replacer and were weaned at 45 days. Immediately after slaughter, the animals were eviscerated, the entire digestive apparatus was removed from the carcass. The reticulo-rumen was separated, emptied, washed and weighed. Samples were collected from the dorsal sac, pillar area and ventral sac of the rumen, fixed for about 24h in Bouin's solution, dehydrated, embedded in Histosec and cut into 5 mu m sections. Results showed that dry matter intake (DMI) at weaning and post-weaning and weight gain were higher (P < 0.05) in animals that received the pelleted total ration. The weight of the reticulo-rumen accompanied body development and was heavier in these animals. Histologically, after weaning ruminal papillae were more developed in animals that received pelleted total ration. Length of papillae increased with increase of age. The ratio of papillary height to papillary width increased with age in the ventral sac and until weaning (P > 0.05). We conclude that the pelleting process of the total ration favored increased intake, with a 46.7% increase in weight gain and increase in rumen weight and papillae length, suggesting that best results are obtained with this processing. In general, no difference was observed between the results obtained with extruded and ground total ration, although animals fed extruded total ration showed an increase in rumen weight and papillae width.

Perdas endógenas e coeficientes de absorção aparente e real do magnésio em caprinos

Os objetivos deste trabalho foram determinar a absorção aparente, estimar as perdas endógenas fecais e a absorção real do Mg e determinar a ingestão ad libitum da água de beber e a concentração de Mg no soro sangüíneo de caprinos da raças Anglonubiana (AN) e Saanen (SN). Foram usados doze caprinos, seis de cada raça, com 19,8 kg PV médio. Dietas semipurificadas (baixo teor de Mg) à base de quirera de arroz, glúten de milho e celulose foram suplementadas com MgO, para se obterem os níveis de 0,05 (sem supplementação) 0,20 e 0,35% Mg (%MS). Os níveis de Mg influenciaram os coeficientes de absorção aparente de Mg e Ca, com valores médios de 57,8; 73,9; e 73,2% para Mg e 55,7; 39,6; e 49,5% para Ca, para dietas com níveis 0,05; 0,20; e 0,35% de Mg, respectivamente. Entretanto, para os coeficientes de absorção aparente de P, Na e K, não houve efeito de níveis de Mg na dieta. Os resultados de absorção real de Mg apresentaram interação de níveis de Mg e raças. A média para raça NA, no nível 0,05% Mg, foi de 61,0% e para os níveis 0,20 e 0,35% Mg, 77,2 e 73,2%, respectivamente. Entretanto, para a raça SN, as médias foram 73,3; 75,5; e 76,0%, para os mesmos níveis, sem diferenças. A digestibilidade de matéria seca, proteína bruta e extrato não-nitrogenado diminuiu com os níveis crescentes de Mg nas dietas. As excreções fecais (7,0; 20,8; e 34,4 mg/kg PV0,75.d) e urinárias (3,9; 30,8; e 44,6 mg/kg PV0,75.d) de Mg elevaram-se com o aumento dos níveis crescentes de Mg nas dietas. Houve, também, influência dos níveis de Mg dietético sobre as concentrações de Mg do soro sangüíneo (1,74; 2,23; e 2,80 mg/dL para níveis de 0,05; 0,20; e 0,35% de Mg, respectivamente).

Biodigestão anaeróbia dos dejetos de cabritos Saanen alimentados com dietas com diferentes proporções volumoso e concentrado

Avaliaram-se os efeitos da idade do animal e da proporção de volumoso nas dietas sobre a biodigestão anaeróbia dos dejetos de cabritos Saanen. Foram utilizadas as fezes produzidas por cabritos Saanen aos 90, 120 e 150 dias de idade e alimentados com dietas de três relações volumoso:concentrado (80:20, 60:40 e 40:60), representando as dietas 1, 2 e 3, respectivamente. Utilizaram-se biodigestores tipo batelada de bancada com capacidade para 12 litros de substrato em fermentação e 8% de sólidos totais iniciais para determinação das produções e dos potenciais de produção de biogás e metano, da redução de sólidos voláteis e quantificação dos teores de minerais no afluente e efluente. As maiores reduções de sólidos voláteis foram observadas nos substratos preparados com as fezes de cabritos aos 150 dias alimentados com a dieta com relação volumoso:concentrado de 40:60. Os melhores rendimentos de substrato ou fezes foram obtidos com os dejetos dos cabritos de 120 e 150 dias de idade alimentados com a dieta com relação volumoso:concentrado 40:60. As maiores concentrações de minerais nos biodigestores foram observadas para as fezes de cabritos de 150 dias de idade alimentados com a dieta com relação volumoso:concentrado 40:60. A biodigestão anaeróbia é eficiente na remoção de coliformes nos dejetos de caprinos, proporcionando efluentes com no máximo 4,3 × 10² coliformes totais termotolerantes por grama de material.

Biodigestão anaeróbia de dejetos de caprinos obtidos nas diferentes estações do ano

Foram utilizados dejetos produzidos por caprinos, em diferentes estádios fisiológicos e submetidos ao mesmo regime alimentar, nas quatro estações do ano. O objetivo foi avaliar o efeito das estações do ano sobre a digestão anaeróbia de resíduos de caprinos em biodigestores modelo batelada com volume útil de 60 L de substrato em fermentação e mantidos sob temperatura ambiente. Foram avaliadas as produções de biogás, as reduções de sólidos voláteis (SV), os potenciais de produção (m³ de biogás/kg de substrato, de estrume, de sólidos totais (ST) ou sólidos voláteis), os números mais prováveis de coliformes totais e fecais, e a composição do biogás. As reduções de SV foram de 38; 34; 33 e 39% para o verão, outono, inverno e primavera, respectivamente. Os totais de biogás produzidos foram de 1,06 m³ no verão, 0,88 m³ no outono, 0,88 m³ no inverno e 0,99 m³ na primavera, e os potenciais de produção médios foram de 0,02 m³ de biogás/kg de substrato e 0,2 m³ de biogás/kg de estrume para todas as estações. As reduções médias de coliformes totais e fecais foram de 99,99% em todas as estações, e os teores máximos de CH4 no biogás foram 88,3; 84,6; 80,6 e 79,2%, para o verão, outono, inverno e primavera, respectivamente.
