Manejo de "sequestro" na recria de bovinos de corte durante o período de transição secas-águas

Abstract

As a productive alternative to reduce the production cycle in rearing beef cattle, to improve the conditions of the pastures, in addition to also being an option when animals lack food in the pasture, the "sequestration" technique can be used (confinement, Thus, the present research project, carried out in two commercial beef cattle farms, evaluated the productive and financial viability of the "sequestration" technique. (1,423) beef cattle, from purchase, ringed, with 329.95 kg of average live weight were evaluated. Of this total, 909 animals from São Judas Tadeu (1) were allocated in 8 confinement corrals. On the other farm, Nossa Senhora de Fátima (2), 514 animals were used, allocated in leisure areas of the pasture modules. In the year 2022, on farm 1, the average daily gain was 0.512 kg and the total cost of the operation was R$247,742.90. Comparing the year 2022 with the year 2021, considering animals on pasture and in “sequestration”, there was an increase of 0.05 AU/ha, 5.4%, at the beginning of the rainy season, and 0.26 AU/ha , equivalent to 20.5% more in stocking, with a total of 731 more animals in the same area and with 79% less rain than in 2021. On farm 2, the average daily gain was 0.661 kg and the total cost of the operation was R$174,889.10. Comparing the year 2022 with 2021, there was an increase of 0.13 AU/ha, 10.6%. However, this positive result was not maintained, with a decrease of 0.11 AU/ha, -7.4%, in December. Evaluating each farm separately, considering the year 2022 with and without the “kidnap”, in a very optimistic scenario, we would have a capacity in December equal to the capacity at the beginning of the waters of 2021. With that, coincidentally, the two farms would have less 0.39 AU/ha, in percentage, farm 1 would have -30.7%, and farm 2 -26.2% in capacity, which would result in a less balance in reais per arroba of R$ 2,476,340 .1 on farm 1 and R$ 793,540.8 on farm 2. Now doing the account at the end of the sequestration, farm 1 had a total profit of R$ 104,447.69 and a result per hectare of R$ 66.62. Farm 2 had a total loss of BRL 222,637.19 and a negative result per hectare of BRL 443.14. With this negative result on farm 1 being a reflection of the lower amount of rainfall in 2022 compared to 2021, -20.6%, and the large infestation of leafhoppers that occurred there. So, positive productive results were obtained both on farm 1 and on farm 2. Looking at the profitability of the “sequestration”, farm 1 obtained a positive result, while farm 2 did not. Taking into account the use or not of the strategy in 2022, the two farms would have worse results if this had not been carried out.
