Book excerpt: IMPORTÂNCIA - O milho verde pode ser consumido nas mais diversas formas, in natura ou como ingrediente para a fabricação de bolos, sorvetes, pamonhas e uma série de outros alimentos, industrializados ou não. O cultivo do milho verde é uma atividade que vem crescendo muito, em função de sua lucratividade e da diversificação de seu uso. A área estimada com essa atividade, no Brasil, é cerca de 102.325 hectares, com a produção de 292.138 toneladas de espigas. Os três estados maiores produtores são Minas Gerais, com 21,12% da produção nacional, São Paulo, com 20,09%, e Goiás, com 18,69%. As produtividades médias de espigas comerciais, na última safra, nos três estados foram, respectivamente, 4.812 kg/ha, 5.277 kg/ha e 5.364 kg/ha. Cerca de 68,40% da produção colhida no país foi comercializada, sendo que 25,92% dessa parcela foi destinada à indústria. O restante, 32,60% do total da produção, é para consumo próprio do produtor. ESCOLHA DE CULTIVARES - A crescente demanda por "milho verde de qualidade" obrigou as empresas produtoras de sementes de milho para uso de grãos secos a desenvolverem cultivares que atendam às exigências do mercado consumidor in natura ou para indústria de conservas alimentícias com as seguintes características: grãos dentados amarelos, espigas grandes e cilíndricas, sabugo branco, boa granação, pericarpo fino e bom empalhamento, com longevidade de colheita e de prateleira. Ainda devem apresentar boa resistência às doenças e pragas que atacam as espigas. Existe no mercado brasileiro de sementes mais de uma dezena de cultivares de milho indicadas pelas empresas produtoras como sendo adequadas para consumo verde in natura. PLANTIO - O cultivo do milho verde pode ser realizado o ano todo, desde que as condições climáticas permitam e que possa ser irrigado. O período em que não chove regularmente é o melhor para a comercialização em função da elevação do preço e em face da pequena oferta de milho verde no mercado. O plantio deverá ser escalonado, para atender a demanda do mercado durante todo o ano. O intervalo entre um plantio e outro (escalonamento) deve ser feito em função da demanda e da distância do mercado consumidor, levando-se em consideração também o ciclo da cultivar. No plantio de verão, colhe-se milho verde mais cedo (cerca de 90 dias) e, no inverno, um pouco mais tarde (cerca de 120 dias). DENSIDADE E SEMEADURA DE ESPAÇAMENTO - O rendimento de espigas comerciais de uma lavoura de milho verde é determinado pela cultivar, pelas condições edafoclimáticas do local e pelo manejo da lavoura, especialmente a densidade de semeadura e o espaçamento entre linhas. A densidade de semeadura varia de 30.000 a 50.000 plantas/ha em função principalmente das cultivares. A maioria se enquadra na categoria de 40.000 a 45.000 plantas/ha, em que se verificam os maiores rendimentos de espigas comerciais. Os espaçamentos mais largos, de 80 cm a 1 metro, devem ser preferidos para facilitar a movimentação de colheita e por possibilitarem melhores espigas comerciais. ADUBAÇÃO - A adubação deve ser feita com base na análise do solo, pois é através dela que se fazem as recomendações para o uso de insumos: corretivos (calcário e outros) e fertilizantes (macro e microelementos). A análise do solo determina também as prováveis limitações que as plantas poderão sofrer durante o seu ciclo vegetativo e, com isso, identificam-se os insumos a serem aplicados de maneira mais econômica ao sistema solo/planta. Em solos com deficiência de zinco, aplicar 7,5 kg/ha de sulfato de zinco por ano ou utilizar fórmulas que contenham zinco na composição. Em virtude de se colherem as espigas e também todo o resto da planta, deve-se ter o cuidado de monitorar o nível de potássio no solo após cada maior parte, nos restos culturais (palhada). Sendo assim, deve-se repor esse elemento juntamente com a adubação nitrogenada de cobertura no máximo 25 dias após a emergência das plantas. TRATOS CULTURAIS E FITOSSANITÁRIOS - São os mesmos praticados para o milho comum, tendo-se o cuidado de manter a cultura sem a presença de plantas daninhas até a colheita para facilitar o operação. O controle das plantas daninhas pode ser mecânico ou químico, através de herbicidas específicos para cada tipo de milho (doce ou normal). No controle fitossanitário, tanto das doenças como dos insetos, deve-se ter cuidados especiais, principalmente com os que atacam as espigas, preservando o período de carência de cada produto devido à colheita do milho verde ser mais cedo. Todos os produtos químicos devem ser usados sob orientação técnica. COLHEITA E TRANSPORTE - O milho verde deve ser colhido com os grãos no estádio leitoso, apresentando de 70 a 80% de umidade. A colheita deve ser efetuada nas horas mais frescas do dia, para que as espigas cheguem ao mercado consumidor em bom estado de conservação. O ponto de colheita é muito variável, em função das condições climáticas resultantes de diferentes épocas de semeadura ou da região onde a lavoura foi instalada. De modo geral, verifica-se que, nos plantios de verão, quando a lavoura se desenvolve em condições de temperaturas mais elevadas, a colheita é realizada entre 70 e 90 dias após o plantio (20 a 25 dias após a polinização, enquanto que nos plantios realizados nos meses mais frios o ciclo pode se prolongar até 120 dias. O transporte deve ser feito o mais rápido possível e nas horas mais frescas, por ser um produto perecível, indicando que a lavoura deve ser mais próxima possível do mercado consumidor ín natura ou da indústria de conservas alimentícias. O transporte pode ser feito em caminhão aberto ou em caminhão furgão frigorífico. PÓS-COLHEITA - Para se obter sucesso na pós-colheita, é necessário ter conhecimento do processo fisiológico do milho verde, bem como de sua composição química, que pode variar em função do genótipo, do tipo de solo onde foi cultivado, dos fertilizantes utilizados, das condições climáticas e do estádio de maturação. As espigas de milho verde despalhadas para consumo ín natura devem ser embaladas em bandejas especiais cobertas com papel filme de PVC esticável, ou PD- 941. para ser comercializado nos balcões refrigerados dos supermercados. conferindo, assim. ao produto características de alta qualidade na pós-colheita. Além da embalagem, a temperatura também exerce papel fundamental na preservação do produto para comercialização por um período mais longo. A embalagem influi no processo metabólico das espigas no que se refere à entrada de oxigênio, permitindo trocas gasosas importantes para a respiração aeróbica do produto. O metabolismo da espiga continua ativo mesmo depois da colheita, o qual pode ser alterado em função das condições dos locais de armazenamento. APROVEITAMENTO DOS RESTOS DAS PLANTAS - Os restos das plantas, colmos e folhas, acompanhados das espigas não comercíais, após a colheita, podem ser aproveitados na alimentação animal, colocando diretamente no cocho ou ensilando, para tratamento de bovinos no período seco. Apesar de não conter a grande maioria das espigas, ainda assim o material é rico em vitaminas do complexo B, carboidratos, vitamina E e proteínas. O agricultor deverá esperar entre duas e três semanas antes de ensilar o material, pois o teor de matéria seca é inferior a 25%, o que propicia ambiente favorável à proliferação e ao desenvolvimento de bactérias produtoras de ácido butírico e também a perdas de princípios nutritivos, por lixiviação, e intensa degradação de proteínas.

Book excerpt: Nutrition is the key driver of animal health, welfare and production. In agriculture, nutrition is crucial to meet increasing global demands for animal protein and consumer demands for cheaper meat, milk and eggs and higher standards of animal welfare. For companion animals, good nutrition is essential for quality and length of life. Animal Nutrition examines the science behind the nutrition and feeding of the major domesticated animal species: sheep, beef cattle, dairy cattle, deer, goats, pigs, poultry, camelids, horses, dogs and cats. It includes introductory chapters on digestion and feeding standards, followed by chapters on each animal, containing information on digestive anatomy and physiology, evidence-based nutrition and feeding requirements, and common nutritional and metabolic diseases. Clear diagrams, tables and breakout boxes make this text readily understandable and it will be of value to tertiary students and to practising veterinarians, livestock consultants, producers and nutritionists.

Available in PDF, EPUB and Kindle. Book excerpt: The world is losing species and biodiversity at an unprecedented rate. The causes go deep and the losses are driven by a complex array of social, economic, political and biological factors at different levels. Immediate causes such as over-harvesting, pollution and habitat change have been well studied, but the socioeconomic factors driving people to degrade their environment are less well understood. This book examines the underlying causes. It provides analyses of a range of case studies from Brazil, Cameroon, China, Danube River Basin, India, Mexico, Pakistan, Philippines, Tanzania and Vietnam, and integrates them into a new and interdisciplinary framework for understanding what is happening. From these results, the editors are able to derive policy conclusions and recommendations for operational and institutional approaches to address the root causes and reverse the current trends. It makes a contribution to the understanding of all those - from ecologists and conservationists to economists and policy makers - working on one of the major challenges we face.

This book was released on 2008-05-20 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written to help identify major gaps in our knowledge of how gender and age affect psychiatric diagnoses and to stimulate much-needed research to fill these gaps, Age and Gender Considerations in Psychiatric Diagnosis serves as both a valuable short-term source for the DSM-V Task Force and its disorder-specific workgroups, and a long-term guide for future studies that will contribute to revised psychiatric classifications in these three areas. Here, 47 experts present findings in three areas of psychiatric research that historically have been neglected but rightfully have received increasing attention in recent years and thus are worthy of investigation into their clinical features, etiology, and course: 1. Significant gender differences in prevalence, symptom profiles, and risk factors for mental disorders, including neurodevelopmental, neurophysiological, and environmental factors for men and women that cut across diagnostic categories-for example, the critical importance of gender in how psychiatric illness develops and presents; DSM's approach to gender to date; and relevant research findings and gaps in the epidemiology, etiology, and pathophysiology of disorders and the gender-related expression of psychopathology, including the controversial and complex question of whether DSM should have different diagnostic criteria for men and women. 2. Mental disorders in infancy and early childhood, including diagnosis and measurement of psychopathology; PTSD and social and cognitive factors related to the experience of stress; reactive attachment disorder (unique in part because of its specificity to early childhood); mood and anxiety disorders and difficulties in diagnosis; sleep disorders, including two new disorders, Night-Waking Dysomnia and Sleep-Onset Dysomnia; feeding disorders, including the need to address overeating and overfeeding (especially given the alleged U.S. epidemic of obesity); early childhood manifestations of behavior disorders; and early symptoms and diagnosis of autism. 3. Mental disorders in the elderly, such as dementia and depression, once considered normal consequences of aging but now understood to represent mental disorders, including the need to identify specific brain structure abnormalities, biomarkers, and the many contributing biological, psychosocial, and environmental factors of mental illness in late life and to understand their roles in the elderly to better diagnose and monitor disease progression. Written for clinicians and researchers alike, this thought-provoking compendium contributes critical information that helps enhance our understanding of the causes of mental disorders, develop effective preventive and treatment interventions, and inform future editions of DSM and ICD.

Available in PDF, EPUB and Kindle. Book excerpt: The capybara is the neotropical mammal with the highest potential for production and domestication. Amongst the favorable characteristics for domestication we can list its high prolificacy, rapid growth rate, a herbivorous diet, social behavior and relative tameness. The genus (with only two species) is found from the Panama Canal to the north of Argentina on the east of the Andes. Chile is the only country in South America where the capybara is not found. The species is eaten all over its range, especially by poor, rural and traditional communities engaged in subsistence hunting. On the other hand, in large urban settlements wildlife is consumed by city dwellers as a delicacy. The sustainable management of capybara in the wild has been adopted by some South American countries, while others have encouraged capybara rearing in captivity.
