Abstract:

The effect of different intake levels of VB1 and VB2 on plasma of VB1,E-TKA,TPP effect,urinary of VB1 excretion and plasma of VB2,E-GRAC,urinary of VB2 excretion was studied to get VB1 and VB2 requirements of Yili horse.Twenty-five healthy male Yili horse,with six-month old and average body weight of (117.12±13.33)kg,were randomly divided into 5 groups.The horses in trail groupⅠ,trail groupⅡ,trail groupⅢ,trail group Ⅳ and trail group Ⅴ,were fed with the same basal diet and added 0,10,20,30,40 mg of VB1 and added 0,7,14,21,28 mg of VB2,respectively.The results showed that VB1 level,E-TKA in plasma,urinary of VB1 excretion were significantly increased (P <0.05), and TPP effect were extremely significantly reduced with the increasing intake of dietary VB1 (P <0.01).With the increasing intake of dietary VB2,plasma VB2 level,urinary of VB2 excretion were improved significantly (P <0.05),and E-GRAC were reduced extremely significantly (P <0.01).Based on the results in this study,the optimal requirements of VB1 and VB2 were 33.32 and 18.73 mg/(horse·d) in six-month old Yili horse,respectively.
