Effects of supplemental fructo-oligosaccharide and mannanoligosaccharide on nutrient digestibilities, volatile fatty acid concentrations, and immune function in horses

Bu araştırma, atların yemlerine katılan frukto-oligosakkarit (FOS) ve mannan-oligosakkaritin (MOS) besin maddelerinin sindirilme dereceleri, dışkı pH’sı ve uçucu yağ asitleri kompozisyonu ile immun sistem üzerine etkilerini incelemek amacıyla yapılmıştır. Araştırma 4×4 Latin kare deneme düzenine göre yürütülmüş ve değerlendirilmiştir. Dört dönem halinde yürütülen araştırmanın, her bir dönemi 12 günü adaptasyon, 6 günü dışkı ve 2 günü kan numunesi toplama olmak üzere 20’şer gün, toplam 80 gün sürdürülmüştür. Her dönemde dört gruptan biri kontrol olarak tutulmuş, diğer gruplar ise, rasyona 30 g/gün FOS ilave edilen grup, 30 g/gün MOS ilave edilen grup ve 15 g/gün FOS + 15 g/gün MOS ilave edilen grup şeklinde oluşturulmuştur. Dışkı pH’sı ve uçucu yağ asitleri kompozisyonları arasındaki farklılıklar önemli bulunmamıştır (P > 0,05). Gruplara göre besin maddelerinin sindirilme dereceleri arasında farklılıklar önemli bulunmamıştır (P > 0,05). Serum IgA, IgG ve IgM konsantrasyonlarında da önemli bir değişiklik oluşmamıştır (P > 0,05). Ergin atların rasyonlarına FOS, MOS veya FOS + MOS ilavesinin bağırsak sağlığı ve immun sistem üzerinde etkisi bulunmamıştır.

Atlarda frukto-oligosakkarit ve mannan-oligosakkarit kullanımının besin maddelerinin sindirilme dereceleri, uçucu yağ asitleri ile immun sistem üzerine etkileri

This research was performed to study the effects of fructo-oligosaccharide (FOS) and mannan-oligosaccharide (MOS) on nutrient digestibilities, fecal pH and volatile fatty acids compositions, and immune function in adult horses. Four adult Thoroughbred horses were used in a 4×4 Latin Square design with 20-day treatment periods. A 12-day adaptation phase was followed by 6-day collection of feces and 2-day blood sampling phases. Four different treatments were administered: 1) Control (no supplemental FOS or MOS; 2) 30 g of FOS/d; 3) 30 g of MOS/d; 4) 15 g of FOS+15 g of MOS/d. There were no differences among treatments in the fecal pH and volatile fatty acids compositions (P > 0.05). Nutrient digestibilities did not differ among treatments (P > 0.05). Also, no differences were found in the IgA, IgG, and IgM levels among the treatments (P > 0.05). Fructo-oligosaccharides, MOS, or FOS+MOS supplementation did not affect gut health and immune system in adult horses compared to control.
