Abstract: To clarify the nutritional and immune status of Honghe Yellow cattle under the grazing condition,60 Honghe Yellow cattles comprising half males and half females were selected and divided into 6 groups according to sex and age (12,36 and 60 months old).Their sera were collected from jugular vein to determine biochemical and immune indicators.As a result,①There were significantly lower contents of total proteins (TP) and globulin (GLOB) within the same sex at the age of 12 months than those at the age of 60 months (P<0.05);The activity of alkaline phosphatase (ALP) and the content of glucose (GLU) were significantly higher in 12-month-old cattle than in 60-month-old cattle within the female (P<0.05),and no significant difference existed for the other serum biochemical indicators between ages.With the increase of age,the contents of TP and GLOB increased while the average activity of ALP decreased in the sera of both males and females.The contents of TP,albumin (ALB),GLOB and aspartate aminotransferase (AST) of females at the three ages were higher than those of males,but the activity of ALP and the content of GLU of males were higher than those of females.② For the same sex,the serum levels of interleukin (IL)-2,IL-8,IL-10,immunoglobulin(Ig)A,IgG,IgM,interferon-γ (IFN-γ),and tumor necrosis factor α (TNF-α) were not significantly different among the three ages (P>0.05),except for a significant difference in serum IL-8 between 12 and 36-month females (P<0.05).The contents of IL-2,IgA,IgG,IgM,IFN-γ and TNF-α in 12,36 and 60-month-old females were higher than those in males (P<0.05).In conclusion,with the increase of age,the serum TP and GLOB contents significantly increased while the ALP activity decreased,and basically,females had higher serum biochemical indexes and immune indexes than females in Honghe Yellow cattle.
