Abstract

In dairy properties, in order for there to be an increase in profit, it is necessary to increase the efficiency of production factors, especially nutrition, which impacts the fixed cost. Increasingly, a balance is sought between the supply of feed and pasture. The rotational grazing method has been adopted by several producers, as it has good productivity in a smaller area. However, the pastures used in this type of grazing, despite their excellent quality, have higher nutritional requirements. The objective of this work was to carry out an economic analysis of the cost of milk production, through the implantation of rotational grazing, and exchange of native pasture for Brachiaria brizantha cv. marandu, on a family farm. This work was prepared in the city of Foz do Iguaçu. An area of 6300m2 was used, divided into 28 paddocks of 225m2 using an electric fence. The total cost of production was R$6,047.40, with a positive margin of R$5.143.61 per year. According to the results obtained in the economic analyses, it is concluded that the implantation of rotational grazing and the exchange of native pasture for Brachiaria brizantha cv. Marandu is a viable management, since the income generated by the sale of milk was sufficient to cover the total costs of production.

Highlights

Brazil ranks fourth in the world ranking of milk production
The state of Paraná alone this year produced an average of 4.37 billion liters of milk, of which western Paraná was responsible for 19% (IBGE, 2018)
The average area occupied with pastures in the state is 16.6 hectares (IPARDES, 2009)

Summary

Introduction

Brazil ranks fourth in the world ranking of milk production. In 2018, the Southern region accounted for 34% of the country's total production (ANUÁRIO LEITE, 2019). The state of Paraná alone this year produced an average of 4.37 billion liters of milk, of which western Paraná was responsible for 19% (IBGE, 2018). Dairy cattle in the state of Paraná is a typical activity of family farming, representing approximately 85.1% of the state's producers (SEAB, 2018). Most of these producers use pasture as the main source of food for animals. The average area occupied with pastures in the state is 16.6 hectares (IPARDES, 2009)
