ABSTRACT This study aimed to investigate the influence of forage production area, concentrate supply, and farm labor on characterization of milk production systems (MPS) and their productive results. Milk volume data provided in 2014 by 110 dairy farms located in the eastern region of Santa Catarina State, Brazil, were obtained from a dairy industry. Forty-four farms with different production levels were selected, in which interviews were carried out aiming to characterize the management practices related to forage production area, concentrate […]

ABSTRACT The objective of this study was to evaluate milk quality for somatic cell count (SCC) analysis and total bacterial count (TBC) in agroecological production systems and conventional systems, relating them to the frequency of milking practices and types of facilities. The study was conducted in 2013 and 2014, in the western region of Paraná State, Brazil. We used a semi-structured questionnaire to identify management practices of producers in the 17 dairy systems (DS) in the city of Diamante d’Oeste […]

ABSTRACT The objective of this paper was to analyze financial management practices in dairy production systems. More specifically, we sought to identify which milk producers adopt financial management practices. We conducted 55 semi-structured questionnaires in the Western Region of Paraná. The data were processed through descriptive and multivariate statistical analysis. The analysis of hierarchical clusters defined, based on variables related to financial management practices, two distinct groups. The first group included milk producers who do not adopt financial management practices […]

The objective of this study was to identify groups of technologically homogeneous milk producers in the State of Goiás and calculate the gains for inefficient producers, considering the ones of better performance (benchmarks) with the same technological level, i.e., in the short term, and the benchmarks in higher technological level, i.e., in the long term. Multivariate statistical analysis techniques were used for the formation of homogeneous producer groups and multi-stage model of data envelopment analysis (DEA) for the estimation of […]

Objetivou-se identificar a tipologia e as características dos sistemas de produção de leite de cabra. Foram pesquisadas 70 propriedades agrárias. A técnica utilizada foi análise multivariada com a formação de cluster, com identificação de cinco diferentes grupos de sistemas de produção. Os sistemas de produção foram tipificados pela eficiência técnica e econômica, como grupos 1 e 2, considerados de nível tecnológico alto, grupos 3 e 4, de nível médio, e grupo 5, de nível baixo. Os sistemas de nível tecnológico […]

Avaliou-se, por meio de técnicas multivariadas, a divergência genética entre clones de palma forrageira (Opuntia ficus-indica Mill.), em um experimento instalado na Estação Experimental da Empresa Pernambucana de Pesquisa Agropecuária – IPA, Caruaru – PE. O delineamento foi em blocos casualizados, com três repetições. Os tratamentos foram 19 clones de palma do Banco de Germoplasma do IPA. Foram mensuradas: a) medidas em artículos, conforme a ordem: comprimento, largura, espessura, número e peso da matéria verde. b) medidas por planta: presença […]

A degradação ruminal da matéria seca (MS) e a da proteína bruta (PB) de alguns alimentos foram deterninadas pela técnica in situ, usando-se três vacas Holandesa. Os alimentos concentrados foram moídos em peneira de 2 mm e os volumosos e a raspa de mandioca, em peneira de 5 mm, e incubados em sacos de náilon (53µ). A degradabilidade efetiva (DE) da MS (5%/h) de silagem de milho, silagem de sorgo, milho, sorgo, farelo de trigo, triticale, raspa de mandioca, polpa […]
