PERFIL DOS PRODUTORES RURAIS DO MUNICÍPIO DE QUIXERAMOBIM NO ESTADO DO CEARÁ

The present work had as main objective to identify and to characterize rural producers as well as it productive systems. The characterization of the small producing native of northeastern Brazil, supported in a scientific knowledge about the local agricultural reality, is fundamental to elaborate politics of diffusion of technologies, programs and projects of agricultural development for the northeast. The disorganization of the productive chain and the little articulation among the different segments of this chain, allied the lack of zootecnic control, to the genetic standard bass of the flocks and the technical, managerial less information and of market of the producers it has been resulting in low productive indexes dedicated to the exploration of the cattle raising in Brazil. For initiative of the Clerkship of Agriculture of Quixeramobim a questionnaire was elaborated in partnership with IBAMA, SEBRAE and EMATERCE. The same was applied in the 11 districts of the municipal district in an eclectic and including way, in order to obtain a sampling the most representative possible. The great totality of the producers maintains a typical profile of the family agriculture, with emphasis in the subsistence, little technological progress and little specialization. Turning them less competitive and more susceptible to the adversities, be of physical, climatological, managerial nature or the commerce

Exigência de Lisina para Suínos na Fase de 10 a 20 kg nas Condições do Nordeste Brasileiro

One experiment with piglets between 10 to 20 kg live weight was conducted to determine the lysine requirements. Were utilized a total 60 crossbred pigs, 30 barrows and 30 gilts in a randomized block design with four replications and three piglets(two barrows and one gilts or two gilts and one barrow) per experimental unit. The piglets were fed diets containing corn-soybean meal and sesame meal with five lysine levels(0.70, 0.80, 0.90, 1.00 e 1.10%). Average daily gain (ADG) increased linearly (P0.05) was observed. Based on ADG using the linear model and on feed-gain using the descontinous statistical model (LRP), the levels of 1.10 and 0.98% lysine were obtained respectively.O experimento foi conduzido para estimar a exigência de lisina em suínos pesando de 10 a 20kg. Foram utilizados sessenta leitões mestiços, sendo 30 fêmeas e 30 machos castrados, em um delineamento experimental de blocos ao acaso, com cinco tratamentos e quatro repetições com três animais por unidade experimental. Os níveis de lisina em dietas à base de milho, farelo de soja, e farelo de gergelim variaram de 0,7 a 1,10%, com aumento de 0,10%. A média de ganho de peso diário (GPD) aumentou linearmente (P0,05) dos níveis de lisina foi observado sobre o consumo diário de ração e sobre os níveis de uréia no soro sanguíneo. Baseadas no ganho de peso diário usando o modelo linear e para a conversão alimentar o modelo descontínuo LRP (Linner Response Plateau), as exigências de lisina obtidas foram de 1,10 e 0,98%, respectivamente
