Evaluación del crecimiento de terneros charolais en la fase de lactancia sometidos a un manejo semi-intensivo en el Rancho Don Bosco

Abstract

The present research aims with objective to make an evaluation growth at Charolais race calves, during their lactation period under semi-intensive management al Don Bosco´s facility, located in Morona Canton, in Morona Santiago Province. Sixty calves were evaluated, in which thirty-three (33) were males and twenty-seven (27) females, who were taken the following zoometric measurements height at the withers, width of the hip, thoracic perimeter, abdominal perimeter, perimeter of the anterior cane, perimeter of the posterior cane, length of the animal, length Cross - Base of the tailto relate height to the cross, age and live weight. It was used the descriptive measurements to relate height to the cross, age and live weight. It was used the descriptive statistical analysis with tendency and dispersion measures with T – Student tests, and regression and correlation analysis. The average weight was reported at birth with 50.35 Kg +/- 4.68 Kg for males and 45.25 Kg +/- 4.47 Kg for females, getting a weight gain of 1.13 Kg per day, the zoometric index was positive linear trend, relation height to the cross, age in relation to live weight are negative tendency losing 0.0081 Kg per centimeter that increases on height. Taking into account the results, it is recommended to continue with the scientific and technical work in the Charolais race.
