Abstract

Serum magnesium concentration (Mg Conc.) in 200 dairy Friesian CALVES (I03 male and 97 female) AGEd from birth to 4 months in different SEASONs in 2001-2 was investigated to: 1- Determination and comparison of serum Mg concentration in female and male dairy CALVES, 2- to compare the effects of AGE and SEASON on serum Mg concentration in CALVES, 3- the effects of SEASON, AGE and sex on CALVES' serum Mg concentration, 4- determination of probable sub-clinical HYPOMAGNESEMIA in dairy CALVES. Number of females in Spring, Summer, Autumn and Winter were 24, 23, 22, 28 and males were 24, 18, 29 and 32, respectively. Number of females AGEd 1, 2, 3, and 4 months old were 48, 21,12 and 16 and males were 32, 31, 27 and 13, respectively. SERUM MAGNESIUM concentration was estimated in mmol/l using xylidylblue test and magnesium kit (Parsazmun) by spectrophotometer (Pharmacia, LKB, Novaspec, England) of 500 wavelength. Panacea statistical program, normal distribution, ANOVA and Factorial ANOVA were used to analyse the data. Mean serum Mg concentrations in female and male CALVES were 1.06 and 0.79 mm01/1, respectively which was significant (p<0.001). Mean serum Mg concentrations in Spring, Summer, Autumn and Winter were 0.82, 0.96, 0.95 and 0.93 mmol/l, respectively. ANOVA showed no differences between SEASONs, except for males that were differed between Summer and Autumn (p<0.001) and for females between Winter and Summer (p<0.001). Mean serum Mg concentrations in females AGEd 1,2,3 and 4 months were 1.29, 0.82, 0.84 and 0.67 mmol/l and for males were 0.99, 0.78, 0.72 and 0.52 mmol/l, respectively. Serum Mg concentrations in CALVES were differed in different AGEs (p<0.001). Mean serum Mg concentration in 4 months males was differed (p<0.005) from one & two months old and serum Mg concentration in 4 months females was differed (p<0.01) from one month old. Factorial ANOVA between serum Mg concentration and SEASON, AGE and sex showed significant effects (p<0.01) between these variables. It can be concluded that mean serum Mg concentration in females was greater than males. SEASON had no effect on mean serum Mg concentration in female and male CALVES. Serum Mg concentration decreased with AGE and in males reached up to subclinical HYPOMAGNESEMIA at 4 months of AGE. SEASON, AGE and sex had significant effect on serum Mg concentration. Male CALVES at 3 months of AGE in winter and Spring are susceptible to sub-clinical HYPOMAGNESEMIA.
