title: Haematobiochemical parameters of goats fed tannin rich Psidium guajava and Carissa spinarum against Haemonchus contortus infection in India.
abstract: The antihelminthic properties of tannin-rich plants are being explored as an alternative to chemical drugs to minimise the effects of gastro intestinal nematodes (GIN). The present study was, therefore, conducted to investigate the effect of condensed tannins (CT), obtained from regional tanniferous tree leaves, in the Haemonchus contortus infected goats on the heamatobiochemical parameters to assess the goat health. Twelve adult male goats were randomly divided into three equal groups, namely negative control, infected control and treatment. H. contortus infected goats were allocated into infected control and treatment groups and their feeds contained 0 and 1.96 % of CT, respectively. Feeding trial was conducted for the duration of 90 days during which haematological and serum biochemical parameters were monitored on fortnightly basis. The animals ingesting the CT-rich leaf meal mixture had increased levels of haemoglobin, packed cell volume, total protein, globulin, glucose and calcium, and decreased levels of blood urea; indicating a beneficial effect of CT supplementation at the selected level. However, the phosphorus balance, serum albumin levels and serum enzyme activity were not affected significantly. The study revealed that inclusion of CT in the diets of the adult male goats did not pose any threat to the health of the goats. Further, the CT based diet had beneficial impact on the haematological parameters and could therefore be included in small ruminant diets to minimize the impact of GIN.
