Effects of dietary levels of vitamin B1 on growth performance,locomotor performance and serum biochemical indices in racehorses
The aim of this experiment was to study the effects of vitamin B1 levels in diets on growth performance,exercise performance and serum biochemical indexes of racehorses.Fifteen healthy racehorses of 6 months of age and weighing(127.69±10.23)kg were randomly divided into test groupⅠ,test group Ⅱ,and test group Ⅲ.The above horses were fed the same nutritional level of diet daily,and 0,10 mg,and 20 mg of vitamin B1 were added to the diets,respectively,and the growth performance,locomotor performance,and serum biochemical indices of racehorses of the three groups were measured after a 30-day feeding trial.The growth performance,exercise behavior and serum biochemical indexes of the four groups were measured.No statistical difference was seen(P>0.05);in the 30th d of the study,the average speed of 800 m of foals in the test Ⅲgroup was higher than that of the test Ⅰ group and the test Ⅱ group(P<0.05);serum biochemical indexes of foals of all groups decreased with the increase of day age,and there was no significant difference between plasma biochemical indexes of the three groups in the official test on the 0th d(P>0.05);on the 30th d of the trial,the foals of test Ⅲ group had higher serum biochemical indexes than those of the other groups.At 30 d of the test,the serum biochemical indexes were higher than those of the other two groups,but this difference was not statistically significant(P>0.05).Supplementary feeding of vitamin B1 to healthy racehorses can promote the growth of racehorses,improve the blood biochemical indexes,and help to promote the athletic performance of racehorses.
