El Destete Precoz De Becerros Y Becerras Castradas Para Exportación Como Una Alternativa Viable En La Ganadería De Sonora

The study was conducted in Carbo, Sonora, Mexico, in 2018, with the objective of determining the strategies of production and export of castrated calves and calves under favorable conditions of increase in prices by evaluating: 1) Early weaning of calves for export (DPM), 2) Early weaning of castrated calves and calves for export (DPHM) and 3) Control. Sixty animals at random from a group of 100 cows five years of age were selected Charbray race. For each treatment, 30 animals, 15 were female offspring and 15 male offspring. The variables evaluated were: (1) Weight at weaning of calves, (2) Weight of cows at weaning, (3) Weight sale of the offspring; (4) Weight and body condition of cows at weaning, pregnancy rate and calving interval, (5) Production Costs of kilos of meat and (6). Projection of profitability in three scenarios in an area with capacity for 100 animals. All variables were analyzed using analysis of variance (P<0.05). The DPHM showed to be a viable option for increasing the productivity and profitability of farms. The result of the financial analysis shows that the greatest benefit is achieved with the DPHM as it enables the production of calves steadily during the 10 years of the project, compared to the control, which presents lag in production cycles caused by the large number of open days, low calving rates and high production costs.
