Clinical, Haemotological and Biochemical Studies of Induced Frothy Bloat in Goats in South Darfur

Abstract

The current study was conducted to examine the potential of fresh lush alfalfa to induce frothy bloat in goats and to evaluate some physical, haemotological and biochemical parameters. The study was donefrom September 2017 to February 2018 in the Department of Clinical Studies, Faculty of Veterinary Science, Nyala University, South Darfur State. A total of 25 clinically healthy male goats were utilized in the current investigation. Blood samples were taken from these animals before feeding alfalfa (25 samples) as control samples.The animals were feed the plant after fastening for 16 hours and the samples were taken every 2 hours for 24 hours (300 samples). Physical (pulse and respiratory rates, temperature, eye mucous membranes, percussion and auscultation), hematological (Pack cell volume,Total Red Blood Cell Count, Total White Blood Cell Count and Differential of White Blood Cell Count) and biochemical (Serum total protein, albumin, urea, calcium, sodium and potassium) parameters. The changes of rumen fluid (color, odor, consistency and pH) were also recorded using standard methods. The clinical signs of induced froth bloat appeared after 6 hours in goats, there was tachypnea, tachycardia and congested mucous membranes percussion and auscultation revealed tympanic sound and decreased ruminal motility. The pulse and the respiratory rates were significantly (p<0.05) with slight decrease in temperature after 6 hours of induction time. There was significant decrease in PCV and TWBCs with increased of TRBCs and neutrophils at 8 hours of induction time. Lymphocytes, monocytes and eosinophil were decrease at 22 hours of induction time. The changes of rumen fluid were observed with significant decrease of the pH at 6 hours of induction time. Biochemical parameters were also affected by the reaction of plant in the rumen. In conclusion fresh lush alfalfa has a high ability induce a frothy bloat in the goats, because of rapid severe changes of physical, hematological and biochemical parameters and this leading to death of the animal.
