Análisis reproductivo y productivo de tres sistemas de producción bovino del municipio de el Piñón, Magdalena.

Abstract

For the development of this work analyzed the reproductive variables of three systems of bovine production, in order to establish the relationship between these and the low rates of productivity presented. For this research, 35 bovine females were studied in different reproductive states of which 20% were pregnant, 46% were calving and 34% were empty By carefully analyzing the records of each farm it was found that the calving interval is on an average of 480 days, the period of open days averages in 123 days and the percentage of birth and mortality is in an average of 45.5% and 20.9% Respectively. The percentage of empty cows found an average of 33.8% and an average of 19.8% of animals pregnant The weight at birth of the animals was also analyzed and it was found that the calves had an average birth weight of 29.7 kg. This analysis was made taking into account that there is a direct relationship between the reproductive variables and indicies of production, for the development of this study other factors that directly influence the reproductive physiology of the animals were also evaluated, such as: management, nutrition and agro-ecological factors.
