Milk production is an important economic and social activity in Brazil. Failure to meet institutional and market demands for quality and sustainability has led farmers, particularly small-scale farmers, to leave agriculture. The aim of this study was to assess and compare the sustainability of dairy farms in Paraná, Brazil. A semi-structured questionnaire was administered to 75 dairy farm operators. Sustainability indicators were generated on the basis of economic, environmental and social data using exploratory factor analysis. Factor scores were subjected to hierarchical clustering, which resulted in the formation of three groups of dairy farms. Groups 1, 2 and 3 had high, intermediate and low levels of sustainability, respectively. Group 1 comprised large-scale dairy farms with high productivity. Dairy farms with intermediate sustainability (group 2) had medium production capacity, and farms with low sustainability (group 1) had the smallest production scale and capacity. Large-scale dairy farms have greater economic, environmental and social sustainability and are, therefore, more likely to survive in the medium and long term.
Highlights:Farmers' organizations improve access to market information on milk quality. Farmers' organizations improve access to technical information. Buyer-seller relationships are strengthened by farmers' organizations. Farmers' organizations improve access to information on milk quality regulations.Semina: Ciências Agrárias, Londrina, v. 41, n. 1, p. 293-304, jan./fev. 2020Casali, M. et al. AbstractMilk production has great social and economic importance in Paraná, Brazil. However, dairy farmers have abandoned the activity over the past few years because of difficulties in meeting institutional and market demands for increased milk production and quality. Information asymmetry between dairy farmers and market agents may be contributing to this scenario. It occurs when one agent in a transaction has more or better information than another. Information asymmetry can encourage opportunistic behavior and negatively affect the relationship between parties. These problems can be minimized or resolved by horizontal collaboration, such as participation in farmers' organizations, cooperatives, or associations. The aim of this study was to assess the extent of information asymmetry among dairy farmers and investigate whether participation in farmers' organizations strengthens buyer-seller relationships and stimulates compliance with milk quality standards. A total of 204 semi-structured questionnaires were applied to head farmers of dairy production systems in Paraná. Two sets of variables were analyzed: variables related to socio-economic and production characteristics and variables related to transactions between farmers and the dairy industry and the head farmer's knowledge about milk quality regulations.The second set of variables was subjected to common factor analysis, which generated four factors: F1, knowledge about institutional requirements; F2, technical support from the buyer; F3, technical knowledge; and F4, level of trust in the buyer. Dairy farmers who did not participate in farmers' organizations operated under greater information asymmetry and were disadvantaged with regard to F2, F3, and F4 (P < 0.05). Participation in horizontal collaborations can help farmers survive and thrive in the dairy activity.
This study aimed to apply the theory of planned behavior to determine the effects of attitude, perceived behavioral control, and subjective norms on the intention of dairy farmers toward high-grain feeding. Quantitative data were collected through interviews with 150 dairy farmers in Paraná, Brazil. Partial least squares structural equation modeling was used to analyze the data. We observed that farmers with a positive perception of grain feeding (attitude) and a positive perception of their ability to increase the use of grains (perceived behavioral control) had higher intention to increase grain feeding. Social pressure (subjective norm) had no effect on the intention to grain feed. These results can contribute to the development of public strategies and policies that encourage the use of high-grain diets in dairy farms.
Pantaneiro cattle (Bos taurus taurus) is a breed locally adapted to the Brazilian Pantanal. Local breeds are essential for the quality production of organic systems based on planned grazing practices, because of their results in resilient and productive ecosystems, enhancing biodiversity. This study aimed to evaluate the performance of Pantaneira primiparous cows, and systems with reduced use of concentrate, simulating organic production conditions. Five animals, with an average body weight of 396.2 ± 43.5 kg, were kept in individual continuous grazing regimes and supplemented with different concentrate levels (1.2%, 0.9%, 0.6%, 0.3%, and 0.0% of body weight). The animals were allocated at random in a 5 × 5 Latin square design repeated twice during the study time. The cows had a low dry matter and nutrient intake with a reduction in concentrate level, with improvement in neutral detergent fiber digestibility and a reduction in total nutrient digestibility. No changes were observed in plasma glucose levels or urea excretion, but the plasma urea nitrogen decreased with reductions in concentrate levels. There was a reduction in milk yield, but the energy-corrected milk was not affected by the reduction in concentrate levels; furthermore, the milk yield efficiency was not affected. The milk fat content improved with the reduction in concentrate levels. The Pantaneira breed has the genetic potential for the maintenance of competitive production and quality in organic systems.
