Haematological parameters of Catfish (Clarias sp.) fed by immunostimulant added with Cr⁺³ - Yeast (Saccaromices cerevisiae) and Garlic

A study on the effect of immunostimulant feed with additional Cr³⁺-Yeast (Saccharomyces cerevisiae) and Garlic on Haematological Parameters of Catfish (Clarias sp.) has been conducted. There were two types of immunostimulant, a commercial feed combined with Cr³⁺-Yeast and a feed in combination of commercial feed, Cr³⁺-yeast, and garlic. A 180 Catfish with an average of 8.79 g in weight and 11 cm in length were used in the study. Haematological parameters measured were haematocrit level, total leucocyte, phagocytic index, and leucocyte differential. Haematological parameters were observed at day 0, 7, 14 after immunostimulant application, and also one and 5^th days after challenge test. Catfish fed with immunostimulant Cr³⁺-Yeast and garlic combination show higher but not significantly different (P>0.05) haematocrit level (20.5%) than those fed with Cr³⁺-Yeast added immunostimulant (20%). A significantly higher (P<0.05) total leucocyte on immunostimulant added with Cr³⁺-Yeast and Garlic (58.850 sel/mm³) than Cr³⁺-Yeast (41.075 sel/mm³) and only feed (23.650 sel/mm³). Phagocytic index were observed significantly higher (P<0.05) on Cr³⁺-Yeast-Garlic (22%) than Cr³⁺-Yeast (13%). Leucocyte differential were observed lower in monocyte (4%), higher in neutrophil (23%) and highest in lymphocyte (73%) on Cr³⁺-Yeast-Garlic combination compared to Cr³⁺-Yeast combination (14% monocyte, 70.5% lymphocyte and 15.5% neutrophil).
