Fermented medicinal herbs improve hematological and physiological profile of Striped catfish (Pangasianodon hypophthalmus)

Abstract

This study sought to determine the effect of fermented medicinal herbs (FMH), i.e. cutchery (Kaempferia galanga), turmeric (Curcuma longa) and curcuma (Curcuma xanthorrhiza) in combination with molasses and probiotic drink (Yakult), administered orally on the hematological and physiological profile of striped catfish (Pangasianodon hypophthalmus). A complete randomized design (CRD) experiment was used with four levels of treatments, namely P0 (control), P1 (FMH 100 mL/kg), P2 (FMH 200 mL/kg) and P3 (FMH 300 mL/kg) of feed. The fish were kept in a farm in cages at 75 fish/m3 and fed with the experimental diets for 60 days. The results revealed that FMH (P2) dietary administration improved hematological and physiological profile of catfish, i.e total erythrocytes of 2.81 x 106 cells/mm3, hematocrit values of 39.00%, hemoglobin levels of 10.73 g/dL, total leukocytes of 11.41 x 104 cells/mm3, blood glucose 97.33 mg/dL, and total serum protein 4.10 mg/dL compared to controls with 1.89 x 106 cells/mm3, 32.33 %, g/dL, 9.67 x 104 cells/mm3, 67.33 mg/dL, and total serum protein of 3.10 mg/dL, respectively. Moreover, the diet improved special growth rate, feed conversion ratio, feed efficiency and the survival rate of catfish. The hematological and physiological profile of catfish improvement are considered to be due to the content of secondary metabolites of FMH, namely curcuminoids, vitamin C, essential oils, tannins, and flavonoids, which trigger immunostimulation. The presence of curcuminoids provide an antioxidant effect on cell membranes reducing erythrocyte cell membrane damage due to oxidation. Similarly, flavonoids are natural antioxidants, which are credited with the ability of reducing free radicals and anti-free radicals.

A blend of Guava, Bitter, and Neem Leaf extracts improves haematology and resistance to co-infection of Streptococcus agalactiae and Aeromonas jandaie but not Liver health in Nile tilapia

“…Our results indicate that fish fed GBNL can improve the health of fish by stimulating significant increases in levels of WBC, RBC, Hb, and Hct in relation to those fed the control diet. It is believed that the presence of metabolites such as flavonoids, tannins, polyphenols and other bioactive compounds in GBNL [ 33 , 34 , 35 ] accounts for the triggered immunostimulation [ 36 ]. It was noticed that increased levels of haematological variables in Nile tilapia by the application of GBNL did not differ in a dose range between 1 and 10 gkg −1 .…”

Pengaruh Penambahan Larutan Kencur (Kaempferia galanga) Pada Pakan Komersial Terhadap Pertumbuhan dan Kelulushidupan Benih Ikan Lele (Clarias sp)

“…Hal tersebut karena didalam kencur terkandung senyawa yang bekerja sebagai aktifitas inflamasi dan dapat meningkatkan nafsu makan ikan. Senyawa tersebut diantaranya minyak atsiri, polifenol, sineol, kuinon, flavonoid dan tannin (Kurniawan et al, 2020). Dari uraian diatas maka dipandang untuk dapat dilakukannya pengamatan dan penelitian tentang perkembangan dan sintasan benih ikan lele dengan pemberian pakan buatan yang ditambahkan larutan kencur.…”

“…Laju pertumbuhan spesifik (LPS) merupakan presentase penambahan bobot/berat ikan dan laju pertumbuhan harian setiap harinya (Kurniawan et al, 2020). Hasil pertumbuhan berat spesifik ikan lele dengan masa pemeliharaan selama 30 hari didapatkan nilai rata-rata LPS perlakuan A (penambahan larutan kencur 30 ml/kg pakan) menghasilkan LPS sebesar 0,136%, perlakuan B (penambahan larutan kencur 60 ml/kg pakan) menghasilkan 0,14% dan perlakuan C (penambahan larutan kencur 90 ml/kg pakan) menghasilkan 0,15%.…”
