DE LOYOLA ORIYES, Carlos Javier. Annual Behavior of Total Calving and Births on Swine Farms in Camaguey. Rev. prod. anim. [online]. 2016, vol.28, n.1, pp. 50-54. ISSN 2224-7920.

In order to determine overall calving and births in Camagüey, the records of 9 464 Yorkshire/Landrace sows from three swine farms between 2008 and 2013, were evaluated. The variables selected (total calving and births) were registered monthly, and were evaluated by serial seasonal decomposition, using a multiplication model. Overall evaluation of the three farms showed seasonal behavior of the variables, in which the maximum peaks tend to appear in the first quarter of the year, and the minimum peaks occurred in the last quarter. However, different seasonal behaviors were observed on each farm, due to organizational and management practices, and because of the characteristics and conditions of the facilities in use. It is important to determine if these seasonal behaviors are the most appropriate to prevent or reduce newborn deaths caused by the action of the elements on each swine farm. This situation must also be taken into account for decision making.
