Pastureland Management, and Influence on the Economic Response of Breeding Herds

The influence of the main pastureland components on the economic response of breeding herds at the Rescate de Sanguily Company was studied from January 2012 to December 2014. Six breeding farms from Ricardo Flores Farm were chosen in the municipality of Jimaguayú, province of Camagüey, Cuba. Variables of pastureland, and forage resources in general were used. To determine the main components that led to variability of breeding units, a Principal Component Analysis was performed; components with values above the unit were selected. Stocking rates variables over 0.60 were chosen too. The elements related with pastureland management in breeding units were defined (forage area with native and cultivated grass), which explain the more than 40 % variance in all the units under the study. Forage balance is negative in the units, as a result of poor agro technical management of grasslands; however, the expensesincome ratio is positive (between CUP $2 500 and$17 600), caused by the low feeding costs. Activities and resources linked to pasture and forage agro techniques must be prioritized, along with the completion of forage areas

Manejo del pastizal y su influencia en la respuesta económica de rebaños de cría.

Se estudió la influencia de los principales componentes del manejo del pastizal en la respuesta económica de rebaños de cría de la Empresa Genética Rescate de Sanguily, desde enero de 2012 a diciembre de 2014. Se seleccionaron seis unidades de cría de la granja  Ricardo Flores, perteneciente a esta empresa, ubicada en el Municipio de Jima-guayú, provincia Camagüey, Cuba. Se tomaron variables sobre la situación de los pastizales y los recursos forrajeros en general y para determinar los componentes fundamentales que determinan la variabilidad de las unidades de cría. Se utilizó el análisis de  componentes principales, seleccionando aquellos componentes que presentaban un autovalor superior a la unidad y dentro de cada componente principal aquellas variables con cargas superiores a 0,60; se pudo definir que entre los elementos del manejo de los pastizales en unidades de cría, destacan el área de forraje, de pastos cultivados y pastos naturales, que explican más del 40% de la varianza entre las unidades del estudio. El balance forrajero en las entidades es negativo, como resultado de la pobre atención agrotécnica a los pastiza les; aún así, la relación gastos-ingresos es positiva, con ganancias brutas que oscilan entre 2 500 y 17 600 CUP, lo que obedece a los bajos costos por concepto de alimentación. Se requiere priorizar las actividades y recursos relacionados con la agrotécnia de los pastos y forrajes, así como el completamiento de áreas de forrajes.Pastureland Management and Influence on the Economic Response of Breeding Herds.ABSTRACTThe influence of the main pastureland components on the economic response of breeding herds at the  Rescate de Sanguily Enterprise was studied, from January 2012 to December 2014.
