Bu çalışmada, buzağılarda ön midelerde mikroflora ve motilite yetersizliğinin, plazma tiamin HC konsantrasyonuna etkisi araştırıldı. Bu amaç için değişik ırk ve cinste, 45-60 günlük, ön midelerde mikroflora ve motilite yetersizliği olan 12 buzağı (Deney grubu) ve 6 benzer yaşlarda sağlıklı buzağı (Kontrol grubu) kullanıldı. Kontrol grubuna göre, deney grubunda rumen sıvısı bakteri sayısı (p

In this study, the effect of forestomach flora and motility insufficiency on plasma thiamine HCI concentrations in calves were investigated. For this purpose, 12 different breed calves, ageing 45-60 days with forestomach flora and motility insufficiency (Experimental group) and six healthy calves (Control group) were used as a material. Significant increments (p<0.01) in the counts of bacteria of ruminal fluids and significant decrements in the plasma thiamine HCI concentrations in the experimental group of calves were determined when these values were compared to the values of control group of calves. While the number of motile protozoa of the ruminal fluid in a microscopic area were between 1-10, the mean counts of protozoa were 34.333/ml and methylene blue reduction time was of < 5 minutes in the control group of calves, the microscopic examination of ruminal fluid samples revealed no protozoa and methylene blue reduction time was of > 15 minutes in the experimental groups. The result of the study showed that thiamine supplementation is to be considered as a part of treatment of forestomach flora and motility insufficiency.
