Effect of feeding Acacia nilotica pod meal on hematobiochemical profile and fecal egg count in goats

摘要

Aim: This study was conducted to observe the effect of feeding Acacia nilotica pod meal on hematobiochemical profile and gastrointestinal parasitic load in growing goats. Materials and Methods: To experiment was conducted for a period of 3-month on 24 male goats (3? month old, average body weight [BW] 6.50?1.50 kg), distributed into four groups of six animals each. The experimental animals were fed graded level of A. nilotica pod meal (0%, 10%, 20% and 30%) mixed in concentrate mixture equivalent to tannin concentration of 0%, 1.91%, 3.82% and 5.73% in the total mixed ration I, II, III and IV, respectively, but ad libitum measured quantity of green sorghum fodder ( Sorghum bicolor ) feeding. The blood samples were collected from experimental goats during the feeding experiment for the examination of different hematological indices and serum biochemical profile to know the overall health status of animals and standard method was followed to analyze the samples. Fecal sample was collected directly from the anus of goats by inserting middle finger and kept the samples in labeled polythene bag. Further fresh sample was processed and examined by McMaster Technique for eggs per gram and oocysts per gram. It gives accurate information regarding severity of infection. Results: The feeding of babul pod meal did not address significant changes about the hematological parameters among various treatment groups. The lymphocyte count was significantly higher (p=0.07) in T3 group as compared to control and increase with increase in level of babul pod meal in the diet. Blood urea nitrogen (BUN) level was 4.86 and 6.59% lower in T1 and T2 group as compared to control and inversely proportional with level of supplement in ration. The decrease in BUN reflected good dietary protein metabolism happened in animals supplemented with babul pod meal. Serum creatinine level was significantly lower (p<0.01) in T2 group as compared to control. The creatinine level was 20.17% lower in T2 group as compared to control. Haemonchus and Coccidian egg count was significantly reduced (p<0.01) in T2 and T3 group followed with T1 as compared to control group. Conclusion: The metabolic status of the animal was not affected with the supplementation of babul pod meal, however, lower serum creatinine level and remarkable reduction in nematode, as well as protozoan egg count in the treatment group, showed good health impact of babul pod.
