Resumen
RODRIGUEZ TORRENS, Herlinda de la C et al. Causes that affect production in a Camagüey pig-based business unit, categories involved. Rev. prod. anim. [online]. 2021, vol.33, n.1, pp. 83-89. Epub 12-Abr-2021. ISSN 2224-7920.
Background:
pig production systems are exposed to economic losses from various diseases and health culls. Objective. Establish the order of participation of some causes of mortality in the Business Unit of Mixed Porcine Base, as well as the categories most involved.
Methods:
official information on economic losses due to mortality due to: enteropathies, respiratory diseases, health sacrifices and other causes was compiled in the categories of offspring, pre-fattening and fattening during the five-year period 2012-2016. From it, a linear regression was performed without error to establish the hierarchical relationship between causes of mortality using standardized coefficients (β) and an ANOVA, with Duncan's multiple comparison test, for the degree of affectation of the categories under study.
Results:
losses due to mortality amounted to 113 215.94 CUP; Its causes, all with significant impact, followed a descending order headed by enteropathies, and followed by respiratory diseases, health sacrifices and others. The most affected categories were young and pre-fattening. The prophylactic use of antibiotics prescribed for these rearing stays does not meet the expected effect.
Conclusions:
enteropathies, respiratory diseases, health slaughter and other causes had a significant influence on the mortality of pigs and pre-fattening pigs. The prophylactic use of antibiotics prescribed for these rearing stays does not meet the expected effect.
