Avaliação da rentabilidade financeira da recria de bovinos de corte em pastagem de aveia e azevém em área de lavoura

Abstract

In the Southern of Brazil, soybean planting is widely used as a summer crop and the potential of oats and auourin in winter for cattle grazing is underutilized. The objective of this work was to financially evaluate the breeding of beef steers using oat and auourgrass in a crop area. The study took place in Dois Vizinhos - PR, at são Marcos farm. The consortium of black oats and aesour was implanted in an area of 15.73 hectares, through a sow, in line, on April 10th of 2018. A 62.5 kg of black oat and 20 kg of ryegrass per hectare were sowed, and the animals entered the pasture was on May 26th, 2018 (46 days after implantation. A total of 36 animals (1/2 Marchigiana + 1/2 Angus) were used, 22 females (228 Kg) and 14 males (206 Kg), aged eight to ten months, in continuous grazing until October 5th. A total of five weighings were made in the period of five months. At the last weighing the average female weigh was 278 kg and the average of males was 285 kg. The data analysis was performed on the weight gain of the animals in the grazing period in oats and ryegrass described above, a series of calculations were made and a financial evaluation was obtained with values updated for the year 2021. The rental of a crop plus the gain from cattle breeding, less the costs of implementation of the pasture allow an annual gain of R$ 3,820.82 per hectare (US$ 694.70) and the difference for the annual rental was R$ 416.85/hectare (US$75.79). On a property of 1,000 hectares the difference of the annual gain then stands around half a million reais. Thus, the regrowth of beef cattle in winter pasture is recommended in areas of tillage in the Southwest of Paraná with lease for agriculture in the summer harvest, because it allows greater financial gain than the annual lease, this gain is greater with the use of males than of females.
