The Effect of Feed Additive Containing Vitamins and Trace Elements on the Elements Profile and Growth of Skin Derivatives in Horses

An important role of nutritional supplements in the quality and growth of skin derivatives is not sufficiently explored. The aim of our experiment was to recognize how the application of selected vitamins and an organic source of zinc and copper affects the growth and elemental content of hooves and hairs. Sixteen warm-blooded horses were divided into two groups. Both groups received the same basic feeding ration, which was enriched with a feed additive for the experimental group. The contents of individual elements in hoof and hair samples were established using the atomic absorption spectrometry method. Samples from the experimental group of horses showed a significantly increased amount of zinc (P<0.01), copper and manganese (P<0.05) deposited in the hoof and a significantly decreased (P<0.05) amount of manganese, iron, and calcium deposited in the hair after nine months of monitoring. Differences between initial and final samples of hooves and hair were insignificant in the control group. The growth rate of hair and hoof wall was significantly higher (P<0.01) in horses from the experimental group than from the control one. Horses receiving the feed additive achieved a faster growth of the hoof horn with an adequate quality of hooves in our experiment. The experiment shows that the hair is not a reliable indicator of nutritional status of horses. However, assessing the impact of individual vitamins and trace elements, or the impact of various sources of trace elements on the elements profile and growth rate of skin derivatives of horses should be subject to further observation.

Wpływ dodatków paszowych zawierających witaminy i pierwiastki śladowe na profil pierwiastkowy i wzrost przydatków skóry koni

Znaczenie suplementów diety odnośnie jakości i wzrostu przydatków skóry nie jest dostatecznie zbadane. Celem pracy było ustalenie, w jaki sposób podanie wybranych witamin oraz organicznej formy cynku i miedzi wpłynie na rozwój i jakość kopyt oraz włosów koni. Szesnaście gorącokrwistych koni podzielono na dwie grupy. Obie grupy karmiono taką samą dietą podstawową, którą dla grupy ekspe- rymentalnej wzbogacono o dodatek paszowy. W próbkach kopyt i włosów koni określono zawartość wybranych pierwiastków, przy użyciu atomowej spektrometrii absorpcyjnej.

Po dziewięciomiesięcznej obserwacji, w próbkach pobranych od koni w grupie eksperymentalnej, statystycznie istotnie wzrosła ilość cynku (P<0.01), miedzi i manganu (P<0.05) w rogu kopytowym oraz wyraźnie zmniejszyła się (P<0.05) ilość manganu, żelaza i wapnia zawartego we włosach grzywy. Różnice pomiędzy pierwszymi i ostatnimi próbkami przydatków w grupie kontrolnej były statystycznie nieistotne. Szybkość wzrostu włosa i ściany kopyta była większa (P<0.01) w grupie eksperymentalnej w porównaniu z kontrolną. Konie, którym podawano dodatek paszowy miały kopyta odpowiedniej jakości. Badania wykazały, że włosy grzywy nie są wiarygodnym wskaźnikiem stanu odżywienia koni. Jednak ocena wpływu witamin i pierwiastków śladowych lub wpływu różnych źródeł pierwiastków śladowych na profil pierwiastkowy i tempo wzrostu przydatków skóry koni powinna być przedmiotem dalszych badań.
