Typology of dairy production systems from West Parana State based on production indices and feed used

Abstract

The dairy industry is characterised by a wide diversity of production systems. In this diverse environment, some of the difficulties can be minimised through the grouping of production units through the study of typology. The objective was to characterise the systems of milk production from West Parana State by considering production rates, area, power, facilities, and marketing of milk. To this end, 735 semistructured interviews with dairy farmers were performed by using a questionnaire for management practices and feed that is used on the farms. To obtain the explanatory variables used for principal component analysis (PCA) and hierarchical cluster analysis (HCA), a homogeneous division of 735 farmers in five groups was used. Ten per cent of producers were randomly selected for the performance of field visits to the properties, where a new questionnaire was applied with specific points regarding feeding management on the property, and feed was collected to determine its composition. The collected data were tabulated and feed was ranked based on the classification proposed by the NRC (2001). Analyses of feed were carried out in the Laboratory of Animal Nutrition of Unioeste. The West Parana State has five groups of dairy production systems. There is great variability in the fresh forages that are used, but maize silage is the main forage utilised for fermented feed, and concentrate supplementation is adopted by more than 60% of farms during both seasons. Changes in the levels of feed components are high among systems. Key words: Animal feed. Characterisation of production. Composition of foods. Dairy farming. ResumoA pecuária leiteira é caracterizada por ampla diversidade de sistemas de produção. Nesse ambiente diverso, algumas das dificuldades podem ser minimizadas por meio do agrupamento das unidades de produção através do estudo da tipologia. Objetivou-se caracterizar os sistemas de produção de leite do Oeste do Estado do Paraná considerando os índices de produção, área, alimentação, instalações e comercialização do leite. Para tal, foram realizadas 735 entrevistas semiestruturadas, com produtores de leite, utilizando um questionário guia referente a práticas de manejo e dos alimentos utilizados nas propriedades. Para a obtenção das variáveis explicativas usou-se a análise de componentes principais (ACP) e análise de clusters hierárquicos (CHA), obtendo-se a divisão homogênea dos 735 produtores em cinco grupos. Destes foram selecionados ao acaso 10% dos produtores cada para a realização das visitas a campo nas propriedades, aplicando-se um novo questionário que contemplava pontos específicos do manejo alimentar utilizado na propriedade, bem como a coleta de alimentos para determinação da sua composição. Os dados coletados foram tabulados e os alimentos classificados com base na classificação dos alimentos proposta pelo NRC (2001). As análises dos alimentos foram realizadas no Laboratório de Nutrição Animal da Unioeste. O Oeste do Estado do Paraná possui cinco grupos de sistemas de produção leiteira. ...

Desenvolvimento e aplicação de modelo para avaliação de sustentabilidade em sistemas produtivos leiteiros

“…Dairy production systems had an average of 48 hectares, 42.2 dairy cows, and produced an average of 322.15 liters of milk per day (Table 4). The heterogeneity observed in these DPS is consistent with the findings of other studies carried out in Paraná (IPARDES, 2009;BRITO et al, 2015;YABE et al, 2015;NEUMANN et al, 2016;ZIMPEL et al, 2017). The majority (78.9%) of milk producers relied on a second source of income.…”

“…Dairy production systems in Paraná are highly heterogeneous. Small-and large-scale producers with different technological and productive capacities coexist in the sector (BRITO et al, 2015;YABE et al, 2015;NEUMANN et al, 2016;ZIMPEL et al, 2017). Half of the producers gain more than 50% of their income from milk production.…”

A typology of corporate and family dairy farms in eastern Goiás, Brazil

“…11,326 (BRASIL, 2006). The factors that best described corporate and family dairy farms were determined using exploratory factor analysis (EFA) (BÁNKUTI et al, 2014;NEUMANN et al, 2016;YABE et al, 2015). The EFA is a multivariate statistical technique of interdependence that condenses a set of correlated variables into a smaller number of factors.…”

“…This variable reduction technique can be used to create indicators for decision-making (FÁVERO et al, 2009a). Several authors have used EFA to generate indicators for dairy production systems (BRITO et al, 2015a(BRITO et al, , 2015bLANGE et al, 2016;NEUMANN et al, 2016;ZYMPEL et al, 2016).…”

Technical and economic indicators of milk production systems in the Caiuá sandstone region

“…This is associated with organizational technical factors, such as collaboration between teaching, research and extension institutions, in addition to credit associations, the use of specialized labor, the selection of a herd with greater productivity and an active cooperative structure (Passetti, Eiras, Gomes, Santos, & Prado, 2016). However, there is a great heterogeneity between the producing regions (Capucho & Parré, 2012;Telles, Bacchi, & Shimizu, 2017) and the respective milk producers in Paraná (Lange et al, 2016;Neumann et al, 2016;Passetti et al, 2016). This difference is primarily characterized by the adoption of production techniques, feed supplementation for the dairy herd and genetic enhancements.…”
