چکیده مقاله
Riders believe that taking oral maltodextrin supplements before training and competitions increases blood sugar levels and delays the level of fatigue in horses One of the modified starch derivatives is maltodextrin, which is obtained from the limited hydrolysis of corn starch, which contains polysaccharides and oligosaccharides, it is produced Maltodextrin is actually a complex carbohydrate made from corn, wheat, rice or potato starch, also, this substance contains free glucose molecules And like dextrose, it is directly absorbed through the intestine Therefore, it increases the blood sugar level The aim of this research was to investigate the effect of two doses of oral maltodextrin on blood sugar, lactate and cortisol levels in three Turkmen horses Materials and MethodsThree Turkmen horses were used in this research, their age was between 5 6 years and their weight was between 440 460 kg The horses were housed in individual stalls 4 x 4 meters and were regularly fed with hay and commercial concentrates in three meals a day, and water was freely available to the horses The horses were clinically healthy and were being prepared for speed races This design was a randomized, controlled crossover experiment that was conducted to evaluate the effects of two doses of maltodextrin 100 and 150 grams in feed and before the race They were taken orally Glucose, lactate, and cortisol variables were investigated The order of treatments was defined randomly For 28 days, the first horse was given only hay and concentrate, and the second horse was given 100 grams of maltodextrin in addition to hay and concentrate, and the third horse was given 150 grams of maltodextrin in addition to hay and concentrate On the 29th day, blood samples were taken before and after the competition Blood samples containing 10 ml of blood were collected by sterile venojects containing the anticoagulant EDTA through the veins of the horses Then for 20 It was centrifuged for a minute and the resulting serum was removed using a pipette and approximately 1 ml was kept at minus 18 degrees Celsius for the analysis of glucose, lactate and cortisol Then the blood samples from the test were sent to the laboratory and the analysis results were determined became Statistical analysis of dataThe assumption of normality was checked using the Shapiro Wilk test, and differences between groups for each outcome were tested using a one way analysis of variance ANOVA using a significance level of 5% Both group and speed were considered as fixed factors and horses were determined as a random factor Tukey's test was performed for post hoc analysis The data in the table and graph are presented as the mean and standard deviation Pearson correlation analysis was performed for analysis Data were presented in tables and graphs as mean ± standard deviation Pearson correlation analysis was performed for all variables at a specific level of 1% Conclusion and DiscussionBlood glucose, blood lactate and cortisol at rest were within the reference range and there were no differences between horses Blood glucose and blood lactate did not differ between groups during the race The concentration of serum cortisol in horses that used maltodextrin 100 and 150 grams was higher than that of horses that did not consume maltodextrin in feed 0 grams p < 0 01 The main finding of this preliminary research was that maltodextrin supplementation did not affect the blood sugar level of the horses that participated in this exercise test This observation contrasts with previous research in resting horses, which linked maltodextrin supplementation with elevated blood glucose levels Maltodextrin supplementation increased serum cortisol levels and had no effect on blood glucose and serum lactate in horses subjected to a speed race
