The aim of this study was to determine the effect of a phytogenic additive in sport horses feed rations on faecal macroelements digestibility. The experiment was realized in Riding Centre of the Faculty of Agrobiology and Food Resources, Slovak University of Agriculture in Nitra, using 6 warm blood sport horses (geldings). The control group was fed with crimped barley, meadow hay, feed mixture and mineral premix. The experimental feed rations were supplemented with a phytogenic additive containing a blend of essential oils from origanum, anise and citrus, as well as a prebiotic rich in fructooligosaccharides. Higher digestibility of calcium (Ca) (71.11% vs. 69.09%) and phosphorus (P) (52.74% vs. 47.55%) was determined in horses fed the phytogenic additives (P>0.05). In this group of horses we found significantly (P<0.05) higher digestibility of magnesium (Mg), 64.32% in comparison with the control group (43.55%). Insignificantly differences in sodium (Na) digestibility we found (75.98% in control group vs. 76.58% in experimental group). Significantly (P<0.05) higher potassium (K) digestibility we found in horses fed with phytoadditives (57.11%). In horses fed without phytoadditives we detected significantly (P<0.05) lower digestibility of K (30.55%). In conclusion, we found positive effects of a phytogenic additive on macroelements faecal digestibility in sport horses.

این مطالعه مزرعه ای به منظور بررسی تاثیر استفاده از یک افزودنی حاوی ترکیبات فایتوژنیک بر عملکرد گاوهای شيری تحت تنش حرارتی انجام شد. دمای منطقه در زمان آزمایش از محدوده تنش حرارتی به طور پیوسته بالاتر بود. 204 راس گاو زایش اول در این مطالعه استفاده گردید که در دو سالن با جایگاه فری استال قرار داشتند. گروه اول (شاهد) جیره کاملا مخلوط (حاوی 64 درصد کنسانتره و 36 درصد علوفه) و گروه دوم علاوه بر جیره کاملا مخلوط روزانه با 15 گرم به ازای هر راس دام از یک افزودنی تجاری (مخلوطی از ترکیبات فایتوژنیک و فروکتوالیگوساکارید) تغذیه شدند. دوره ازمایش 35 روز ادامه یافت بطوریکه در طول این دوره مصرف خوراک، تعداد تنفس، تعداد گاوهای حاضر در سر آخور خوراکدهی دو روز در فواصل یک ساعته و برخی متابولیت های خون اندازه گیری شد. مصرف ماده خشک در گاوهایی که افزودنی دریافت کرده بودند نسبت به گروه شاهد بیشتر و تعداد گاوهای حاضر در سر آخور نیز در برخی ساعات از گروه شاهد بیشتر بود. اما تولید شیر و ترکیبات آن، شمار سلولهای بدنی و اکثر متابولیت های خونی تحت تاثیر قرار نگرفت. سرعت تنفس در دامهای دریافت کننده افزودنی، پایین تر از گروه شاهد بود. 25 روز پس از قطع مصرف افزودنی تولید شیر در گروهی که قبلا افزودنی دریافت می کردند به مقدار 5/2 کیلوگرم کاهش یافتو نتایج این مطالعه بر ضرورت نیاز به طراحی تحقیقات بیشتر و دقیق تر جهت بررسی مکانیسم اثر ترکیبات فایتوژنیک بر عملکرد گاوهای شیری تحت تنش حرارتی تاکید می کند.

The aim of the study was to determine the effect of a phytogenic additive on blood serum indicator levels and faecal nutrients digestibility. The experiment was realized in Riding Centre of the Department of Animal Husbandry, Faculty of Agrobiology and Food Resources, Slovak University of Agriculture in Nitra. Total 14 warm blood sport horses (geldings) were used (7 horses in control group, 7 horses in experimental group respectively); Slovak warmblood bred, average body weight 525 ±75 kg and 6.8 ±3 Years. The control group of horses were fed by crimped barley, meadow hay and mineral feed mixture. Feed rations in experimental group were supplemented with a phytogenic additive containing a blend of essential oils from origanum, anise and citrus, as well as a prebiotic rich in fructooligosaccharides. Blood serum was collected 3 times during the experiment, in the beginning of the experiment, and every 45 days. The experiment lasted 90 days. After the 45 days of phytoadditive supplementation we found a tendency of lower concentrations of serum triglycerides (0.07 vs. 0.23 mmol*l-1) and total cholesterol (2.18 vs. 2.27 mmol*l-1) in experimental group of horses (P>0.05). In serum concentrations of glucose, total proteins and urea we find similar values in all of groups. The same tendency we analyzed in activity of AST, ALT, and ALP enzymes (P>0.05). After the 90 days of the phytoadditive supplementation in feed rations of sport horses, we detected a tendency of lower serum triglycerides concentration in experimental group of horses and higher cholesterol, glucose, total protein and urea concentrations (P>0.05). We didn´t find a significant effect of a phytoadditive supplementation on blood serum indicator levels. Higher faecal digestibility coefficient of dry matter was found in experimental group of horses (62.98%) in comparison with control group (56.87%). In control group of horses we detected tendency of lower crude protein digestibility (71.36%) in comparison with phytogenic additive group feeding (72.86%). We analyzed a positive effect of phytogenic additive on organic matter digestibility of feed ration. In experimental group of horses we found significantly (P<0.05) higher organic matter faecal digestibility coefficient (73.31%) in comparison with control group (68.32%). We analyzed insignificant (P>0.05) effect of a phytoadditive on blood serum concentrations during 90 days of experiment. We found positive effect of phytoadditve supplementation on total faecal digestibility of organic nutrients.
