- Abstract
The objective was to investigate the existing relationships between production, sustainability and generational succession of dairy farms in Minas Gerais. Structural Equation Modeling was used to test nine hypotheses identified in the literature on the subject. Socially and economically sustainable properties can contribute to increasing family succession. In addition, properties that produce more milk may have greater possibilities of contributing to young people remaining in the dairy activity. The generational succession was directly influenced by economic and social sustainability and, indirectly, by the scale of production. [ABSTRACT FROM AUTHOR]

Background:thermal environment exerts a direct influence on animal performance. Environmental factors, in different circumstances, may affect milk production and fertility of animals, compromising the profitability of the activity. Under heat stress conditions dairy cows reduce feed intake and, consequently, milk production. Sweating and panting are some of the mechanisms these animals use to relieve thermal stress. In addition, animals often suffer physiological and behavioral changes caused by heat stress.Objective: the goal of the present study was to develop and evaluate a model based on fuzzy set theory to predict rectal temperature (°C), and respiratory rate (breaths per minute) responses of Holstein cows exposed to different environmental thermal conditions. Methods: the proposed fuzzy model was based on data obtained experimentally (5,884 records) as well as from the literature (792 records) referring to the effect of environmental variables on both physiological responses. Input variables of each record were dry bulb air temperature and relative humidity. Output variables were rectal temperature and respiratory rate. Results: the adjusted model was evaluated for its ability to predict response variables as a function of input variables. The model was able to predict respiration rate with an average standard error of 7.73 and rectal temperature with an average standard error of 0.27. Conclusion: a fuzzy model was developed to predict physiological responses. The error (%) of model prediction for respiration rate and rectal temperature was +/- 12 and 0.5%, respectively. Antecedentes: el ambiente termal ejerce una influencia directa en el desempeño animal. Factores ambientales, en diferentes circunstancias, pueden afectar la producción de leche y la fertilidad de los animales, comprometiendo la rentabilidad de la actividad. Bajo condiciones de estrés por calor, las vacas lecheras reducen su consumo de alimento y, consecuentemente su producción de leche. Sudar y jadear son algunos de los mecanismos que estos animales usan para aliviar el estrés térmico. Además de estas consecuencias, los animales a menudo sufren cambios fisiológicos y comportamentales causados por el estrés calórico, causando una reducción en la producción de leche. Objetivo: el objetivo del presente estudio fue desarrollar y evaluar un modelo basado en la teoría de los conjuntos fuzzy para predecir respuestas fisiológicas, temperatura rectal y frecuencia respiratoria, de vacas lecheras de raza holandesa blanco y negro expuestas a diferentes condiciones ambientales. Métodos: el modelo fuzzy propuesto fue basado en datos obtenidos experimentalmente (5.884 registros), también como de la literatura (792 registros), refiriéndose a la influencia de las variables ambientales sobre esas respuestas fisiológicas. Cada registro incluye valores de temperatura de bulbo seco del aire, humedad relativa (variables de entrada), temperatura rectal y frecuencia respiratoria (variables de salida). Resultados: el modelo ajustado fue evaluado para cada variable respuesta y predice estas en función de las variables de entrada. Este modelo fue capaz de predecir la frecuencia respiratoria con un error estándar medio de 7,73 y la temperatura rectal con un error estándar medio de 0,27. Conclusión: un modelo fuzzy fue exitosamente desarrollado para predecir respuestas fisiológicas. El modelo fue capaz de predecir frecuencia respiratoria y temperatura rectal con errores porcentuales de +/- 12 y 0,5%, respectivamente.

Sudorese e respiração ofegante são alguns dos mecanismos que estes animais usam para aliviar o estresse térmico.

Cada registro inclui valores de temperatura de bulbo seco do ar, umidade relativa (variáveis de entrada), temperatura retal e frequência respiratória (variáveis de saída). Resultados: o modelo ajustado foi avaliado para cada variável resposta e prediz estas em função das variáveis de entrada. Este modelo foi capaz de predizer a frequência respiratória com um erro padrão médio de 7,73 e a temperatura retal com um erro padrão médio de 0,27. Conclusão: o modelo fuzzy foi desenvolvido com sucesso para predizer respostas fisiológicas. O modelo foi capaz de predizer frequência respiratória e temperatura retal com erros percentuais de +/- 12 y 0,5%, respectivamente.

GROSS margins , *OPERATING costs , *INDUSTRIAL costs , *REGRESSION analysis , *LABOR pain (Obstetrics) - Abstract
This research aimed to analyze the profitability of 20 demonstration units (DUs) participating in the Balde Lleno program (“Balde Cheio”), in Rio de Janeiro, between January and December 2011. It also sought to identify components with the greatest influence on total and effective operational costs, in addition to their impact on revenues. Data were analyzed with the PASW 18.0 software. The multiple linear regression model was used with the stepwise method to identify production cost components that had the greatest influence on the liquid margin, lucrativeness, and profitability. Regarding the indicators of gross and liquid margin, as well as the result of dairy activity, the economic analysis examined conditions to produce in the short and medium term, but not in the long run, due to a negative result, which would lead to the decapitalization of the producer. The component items of effective operational cost that had greater representativeness on the cost of dairy activity were, in decreasing order, food, labor, and various expenses; in terms of total cost, in decreasing order, the components were food, labor, and the remuneration of the capital invested.

- Abstract
Aimed to apply the Balanced Scorecard (BSC) in a dairy farm with small-scale production, located in the south of Minas Gerais State, Brazil. The survey was conducted from January to December 2013 and the gathering of information was carried out through semi-structured interviews on the spot. As data collection instruments were used personal interviews, document analysis and direct and participant observation. The farm object of study had 216 ha, 80% of this, leased. The activities were dairy farming, corresponding to 80% of revenues, and the cultivation of coffee. The breeding farm was 22 predominantly Holstein cows (¾H) that are loose in the pasture. The daily production was 350 liters average of 15.9 liters of milk per cow in milk, in two daily milkings. The main strength was the low cost of hand labor; while the weaknesses identified were the infrastructure, the lack of management control and planning. The mission created takes into account the increased efficiency in milk production and increase the quality of this product without increasing the herd. At the end, a strategic map, where it was revealed that the objectives growth and efficiency will be achieved taking into account the increase in revenue was proposed. It was found at the end of the study, that the principles of BSC can be applied to a farm producing small milk with some caveats. [ABSTRACT FROM AUTHOR]
