“…Esse baixo nível de escolaridade reflete negativamente na adoção de mudanças tecnológicas na produção, pois dificulta a assimilação de novas informações relacionadas às práticas de manejo produtivo e à qualidade do produto (Vicente, 2004;Oliveira et al, 2013).…”

RESUMO:O artigo caracteriza a produção leiteira no município de Tailândia, Nordeste Paraense, a partir de dados sobre o perfil socioeconômico do produtor, sistemas de produção, comercialização, associativismo, assistência técnica e crédito rural, obtidos em 49 propriedades leiteiras. A idade média dos produtores foi de 52,5 anos, com baixo nível de escolaridade e atuação na atividade há mais de dez anos. A maioria (73,5%) reside na propriedade, mas é natural da região Nordeste do Brasil. A produção de leite é a principal atividade, e a renda é complementada com outras atividades rurais e urbanas. Há participação expressiva dos familiares nas atividades com pequena contratação de mão de obra. A produtividade média das propriedades foi de 5 litros/vaca/dia, com período médio de lactação de seis a oito meses. O sistema tradicional é predominante nas propriedades e, apesar de 79,6% adotarem pastejo rotacionado, apenas 6,12% utilizam capineiras; no período seco, somente 34,7% suplementam o rebanho com farelos de arroz, milho, soja, trigo e resíduos de macaxeira e dendê. Como medidas sanitárias, há conformidade quanto à aplicação de vacina contra febre aftosa, além da prevenção contra parasitas e verminoses. Não há controle e planejamento reprodutivo, o que interfere negativamente no desenvolvimento da produção. A ordenha é realizada manualmente em curral coberto, uma vez ao dia, e apenas 34,7% das propriedades possuem água encanada no local para higiene dos manipuladores, utensílios e animais. Devido à suspensão das atividades do laticínio municipal de Tailândia, a produção de leite e derivados é comercializada informalmente, o que configura um risco à saúde pública. Apenas 20,4% dos produtores obtiveram acesso aos serviços de assistência técnica e 51% não obtiveram acesso a financiamento. A falta de informação, de assistência técnica e de investimentos na produção leiteira gera baixa produtividade e qualidade do produto. ABSTRACT: The article features dairy production in the municipality of Tailândia, northeast

“…Fungi are usually controlled by antifungal agents during preharvest stage; however, these agents often possess adverse effects on the human health and the environment (Vicente, 2004). Repeated usage can also cause some fungi to develop resistance against broad spectrum of fungicides such as benzimidazoles, prochloraz, and imazalil.…”

Filamentous fungi belonging to Aspergilli genera produce many compounds through various biosynthetic pathways. These compounds include a spectrum of products with beneficial medical properties (lovastatin) as well as those that are toxic and/or carcinogenic which are called mycotoxins. Aspergillus flavus, one of the most abundant soil-borne fungi, is a saprobe that is able growing on many organic nutrient sources, such as peanuts, corn and cotton seed. In many countries, food contamination by A. flavus is a huge problem, mainly due to the production of the most toxic and carcinogenic compounds known as aflatoxins. In this paper, we briefly cover current progress in aflatoxin biosynthesis and regulation, pre-and postharvest preventive measures, and decontamination procedures.

“…Foreign scholars have done the studies on numerous aspects of agricultural production efficiency of their respect countries, including its methods, influencing factors and development directions (Goelli and Rao, 2005) [5]. Vincent (2004) adopted the data envelopment analysis (DEA) method to discuss Brazilian agricultural production efficiency, and it was shown that in Brazil, the pesticides and fertilizers had been fully utilized while other agricultural production factors failed to be fully utilized [6]. Krasachat (2000) based the study on the special national conditions of both developing countries and developed countries, analyzed the ways to improve the agricultural production efficiency respectively, and expounded the relationship between such improvements with grain production [7].…”

Agricultural production efficiency is vital to the development level and quality of agricultural production. China is at a crucial stage of agricultural transformation, and it is of great significance to measure and calculate agricultural production efficiency by scientific methods. This paper conducts a case study of Chinese agriculture and Canadian agriculture, and measures and calculates the average values of gross agricultural output and the variations of agricultural production efficiency based on data envelopment analysis. According to the research results, firstly, Canadian agricultural production efficiency is much higher than that of China, holding a leading position in the world. Secondly, from 2005 to 2015, the agricultural production efficiency of both China and Canada showed an overall rising trend, but there were obvious upward fluctuations in Chinese agricultural production efficiency. Thirdly, Chinese technical efficiency showed a rise and then a decline while the scale efficiency showed a decline at first and then a rise, and the overall efficiency showed a rise with fluctuations. At the same time, Canadian agriculture technical efficiency, scale efficiency and overall efficiency were all on the rise with fluctuations, and the efficiency values were significantly higher than those of China. Next, the Malmquist indices of both China and Canada appeared to change, but the rate of change of Canada was lower than that of China. Finally, based on Canadian agricultural production experience and combined with China's national conditions, this paper also puts forward the suggestions on improving Chinese agricultural production efficiency.
