“…The authors determined that the results show considerable regional differences in the impact of the outputs, input prices, and fixed factors on marginal costs. Gonçalves et al (2008) analyzed technical and scale efficiencies of milk production farms in Minas Gerais region of Brazil, considering different production levels and determined that small farmers have the potential to expand their production and productivity, since they were performing with increasing returns to scale. It was also determined that large farmers presented the best measures of technical efficiency, which was explained by factors such as access to rural credit, training, and technical support.…”

-The purpose of this study was to calculate costs of milk production, gross production value, gross margin, absolute profit, and relative profit of dairy cattle farms located in the provinces of east Mediterranean region of Turkey. Primary data were collected from 148 dairy cattle farms designated using the Neyman Stratified Sampling method through surveys. Dairy farms were classified into four groups according to the number of cows. The data belong to the 2012 production season. A single product budget analysis method was used for calculating production costs. According to the results, variable costs amounted to 65.91% of total production costs. Feed cost (86.52%) was the main component of variable costs. The cost of 1 kg of milk, on average, was calculated as USD 0.261. The cost of milk was USD 0.499 on group 1 farms, USD 0.399 on group 2 farms, USD 0.272 on group 3 farms, and USD 0.233 on group 4 farms. Among the farms under study, average gross margin value was negative only on group 1 farm, and positive in all other groups. Absolute profit value was positive only on group 4 farm, and negative in all other groups. The average relative profit of the farms was 0.9067. The expansion of dairy farms could be reached by reducing the feed cost as well as increasing the scale of farms.

“…Estes autores avaliaram os níveis de eficiência técnica em três sistemas de produção alternativos em Minas Gerais utilizando o modelo de fronteira estocástica de produção. Gonçalves et al (2008), por outro lado, estimaram a eficiência técnica de produtores de leite de Minas Gerais a partir da técnica de Análise Envoltória de Dados. Em ambos os estudos, os determinantes da eficiência técnica foram analisados utilizando-se como base modelos de regressão Tobit.…”

RESUMO -O objetivo principal neste estudo foi analisar a influência de variáveis técnicas e econômicas sobre os índices de eficiência técnica de produtores de leite de Minas Gerais ao longo de pontos distintos da distribuição dos índices de eficiência utilizando-se a técnica de regressão quantílica. Os índices de eficiência técnica foram estimados com base em um modelo de fronteira estocástica utilizando-se dados de 875 produtores de leite do estado de Minas Gerais coletados no ano de 2005. Os principais resultados revelaram, na fronteira de produção, que possivelmente está havendo utilização extensiva do fator terra.De modo geral, a variável percentual de vacas em lactação foi a mais relevante na explicação da eficiência técnica em todos os quantis estudados, enquanto o percentual de mão-de-obra familiar utilizado foi importante para explicar apenas os menores níveis de eficiência. Além disso, foi encontrada diferença significativa entre os coeficientes estimados dos quantis em estudo, o que mostra que as variáveis explicativas não têm o mesmo impacto no aumento da eficiência em todos os pontos da distribuição.Palavras-chave: determinantes da eficiência, fronteira estocástica, pecuária leiteira Technical efficiency of milk production in Minas Gerais: an application of quantile regressionABSTRACT -The objective of this study was to evaluate the influence of technical and economic variables on the indices of technical efficiency of milk from Minas Gerais throughout distinct points of distribution of the efficiency indices by the technique of quantile regression. The technical efficiency indices were estimated based on a stochastic frontier model, using data from 875 milk producers in Minas Gerais state, Brazil, collected in 2005. The main results from production frontier showed the extensive use of the land factor. Overall, the variable percentage of lactating cows was the more relevant in explaining technical efficiency in all analyzed quantiles, whereas the percentage of household labor was important to explain only the lower levels of efficiency. Moreover, significant differences between the estimated coefficients of the quantiles were found in the study, which showed that the explanatory variables do not have the same impactation on increasing the efficiency at all points of distribution.

“…The new competitive environment resulting from the transformations in the Brazilian dairy farming, highlighted by authors such as Gomes & Ferreira Filho (2007), Gonçalves et al (2008) and Siqueira et al (2010), boosted the development of the sector. Although the Brazilian dairy farming still has low average productivity, the activity has gradually specialized and, notably, the biggest producers have obtained gains in productivity and efficiency (Alvim et al, 2009).…”

“…Studies of Tupy & Yamaguchi (2002) and Gonçalves et al (2008), who analyzed the technical efficiency of dairy farming, can be interpreted as long-term results, considering that all inputs can be modified. However, this reasoning cannot be applied in the short term, since the level of technology should be considered constant.…”

Technical performance of milk producers in the state of Goiás , Brazil, in the short and long terms

-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 efficiency scores and identification of benchmarks. The results indicated the formation of four groups of producers and indicate that, on average, the dairy farming in Goiás presents mainly characteristics of traditional, less specialized production. Estimated average efficiency for producers as a whole, or efficiency of long-term, was 0.571. The short-term results vary according to the group analyzed, but were higher than the long-term values, indicating that the factor analysis promoted technological homogeneity between the producers of the same group. Results showed a trend in dairy farming of Goiás towards adequacy of the input/output ratio to the standards of less capitalintensive production systems.
