Análisis de los parámetros reproductivos en la ganadería “El Puente” y su impacto en la rentabilidad.

Abstract

The research carried out a quantitative statistical analysis of the reproductive parameters in the “El Puente” cattle ranch located in the Riobamba canton, Chimborazo province during the period 2008-2018, for the analysis of variance and the separation of means, the Duncan statistic was used of each reproductive parameter, the variables evaluated were: reproductive parameters (number of services per conception, calving interval - first heat, calving interval - conception, calving interval - calving, interval between heat) and economic parameters (cost of calf born, cost of cow pregnancy, open day cost). The results obtained registered significant differences, which were: number of services per conception with an average of 2.22 services per cow, taking into account only the conception that managed to end with a born calf; First heat calving interval obtained an average of 71.61 days; Birth-conception interval was recorded 173.58 days; In the calving-calving interval, an average of 451.90 days was obtained; When analyzing the interval between heat, an average of 31.55 days could be obtained. The cost indicators were made in relation to the year 2018, having as results the following: the cost of the open day presented a value of $ 4.34 per cow, taking into account that from the 100 day post parturition that a cow does not arrive at conception it begins to lose economically since the interval between parturitions lengthens, increasing the cost of maintaining the animal; the cost of a pregnant cow is $ 526.57; the cost of the calf born was obtained a value of $ 1,733.12. Results that suggest establishing a heat detection and heat synchronization program in order to reduce the calving interval and permanent training for the people in charge in order to minimize errors and maximize production.
