Comparison of hematologic and biochemical reference values in specific-pathogen-free 1-month-old Yorkshire pigs and Yorkshire-Landrace crossbred pigs

2019

Analysis of hematologic and biochemical values in pigs is an important basis for biomedical research and veterinary clinical diagnosis. Reference values for specific-pathogen-free (SPF) 1-month-old Yorkshire (Y) pigs and Yorkshire-Landrace crossbred (YL) pigs are limited. The present research aimed to describe and compare the reference values for hematologic and biochemical parameters in such pigs. Blood samples were obtained from 90 Y pigs (52 males and 38 females) and 88 YL pigs (55 males and 33 females), all 1 month old and bred in an SPF environment. Among the 16 hematologic and 15 serum biochemical parameters tested, no significant differences between the Y and YL pigs were found except in the concentration of triglyceride (P < 0.05), and heterosis was not observed. Thus, the values determined in this study can be used as basic reference values for 1-month-old Y and YL pigs and will contribute to the use of SPF pigs in biomedical research.
