Vpliv trajanja namakanja sena na vsebnost vodotopnih ogljikovih hidratov in prahu

Vrtačič, Pia (author), Salobir, Janez (mentor)

Rejci in lastniki konj se vedno bolj zavedamo pomembnosti polaganja kakovostne in neoporečne krme. Živali, ki so nagnjene k boleznim, kot sta laminitis in obstruktivna pljučna bolezen, imajo še dodatne zahteve glede vsebnosti vodotopnih ogljikovih hidratov (VOH) in količine prašnih delcev v krmi, ki jo zauživajo. Ena od rešitev za zmanjševanje obeh problemov je namakanje sena. V okviru naloge smo analizirali vsebnost VOH v senu, ki smo ga namakali 20 in 60 minut, ter 3, 6 in 24 ur. Za vsebnost prahu v senu, smo za primerjavo uporabili vzorce iz kvadrastih in valjastih bal, ter jih namakali 10, 20 in 60 minut. Vsebnost VOH najbolj pada prvih 6 ur pri namakanju 24 ur pa je količina VOH za približno 50 % nižja kot v suhem vzorcu. Ugotovili smo, da se z daljšanjem namakanja sena v vodi vsebnost elementov kot so natrij, kalij, kalcij, magnezij in fosfor občutno niža. Pri analiziranju vsebnosti prahu v senu, ki smo ga namakali smo ugotovili le, da je seno smiselno namakati od 10 do 30 minut. Dejanski rezultati, ki smo jih dobili zelo variirajo in nam ne povedo kateri čas namakanja je najbolj optimalen za izločitev prašnih delcev in ali je bolje krmiti valjaste ali kvadraste bale. Glede na rezultate pri analizi VOH, kjer smo primerjali vsebnost le-teh v kvadrasti in valjasti bali bi v našem primeru konjem, ki so nagnjeni k laminitisu, raje polagali seno iz valjastih bal, saj vsebuje manj VOH. V kolikor seno namakamo z namenom nižanja vsebnosti VOH ali količine prašnih delcev, je smiselno zaradi izgub makro-elementov z vodo razmisliti o ustreznosti mineralno-vitaminskih dodatkov, ki jih dodajamo konjem.

• Title: The influence of hay soaking time on the content of water-soluble carbohydrates and dust

Abstract

Horse breeders and owners are becoming increasingly aware of the importance of feed quality. In particular, animals that are more sensitive and susceptible to diseases such as laminitis and chronic obstructive pulmonary disease require special attention to the levels of water-soluble carbohydrate (WSC) and dust particles in their feed. One solution to eliminate WSC and dust particles is to soak the hay in water. In this work we focused on the analysis of WSC content in hay square bales soaked for 20 minutes, 60 minutes, 3 hours, 6 hours and 24 hours. Square and round hay bales soaked for 10, 20, and 60 minutes were used for dust particle analysis. The results show that the content of elements such as sodium, potassium, calcium, magnesium and phosphorus decreases during soaking of hay. The content of WSC decreases especially in the first 6 hours of soaking, and after 24 hours the content is lower by about 50%. Results of soaking vary widely and do not indicate which soaking time is best for dust-sensitive horses and whether it is better to feed hay from round or square bales. However, we believe it is advisable to soak hay between 10 and 30 minutes. As for the results of our analysis comparing WSC content in square and round bales, we recommend feeding hay from round bales to horses prone to laminitis because the content is lower. In any case, if breeders and owners decide to soak the hay, we recommend adding appropriate mineral and vitamin supplements to replace the water loss.
