Abstract

The efficacy of organic zinc amino acid complex(AvailaZn®) on growth performance and immunity of Pangasius catfish (Pangasianodon hypophthalmus) was assigned in CRD with  4 treatments and 5 replicates. The treatments  were control with inorganic zinc 100 ppm (T1) and the other two treatments of zinc 100 ppm at different proportion of inorganic zinc : organic zinc  70:30 (T2) and 40:60(T3) and the treatment of only organic zinc 50 ppm (T4; 50% of control). Pangasius catfish with average weight of  209  g. were stocked in 1,000 liter fiber tanks at the density of 15 fishes per tank and fed treatment diets 3% of  body  weight  twice daily for three months. The results indicated that there were statistical difference (p<0.05) on growth performance in term of body weigh and specific growth rate of  Pangasius catfish fed diet supplemental organic zinc at different levels were higher (P<0.05) than group of inorganic control(T1). The specific growth rate were 0.89, 1.20, 1.16 and 1.27 %/ in T1, T2, T3 and T4, respectively. Feed  conversion ratio were not significantly different(p=0.08) and protein efficiency ratio also were not significantly different(p=0.09). White blood cell count, serum protein, immunoglobulin (IgM), hemoglobin, and super oxide anion in group of zinc amino acid complex were better (p<0.05) than group of inorganic control(T1).  Therefore, using zinc amino acid complex(AvailaZn®) in Pangasius catfish diet can enhance catfish growth performance (p<0.05) and decrease zinc level in the catfish diet by 50% of using inorganic zinc. Supplementation zinc amino acid complex(AvailaZn®) in Pangasius catfish diet is recommended at the level of 50 ppm for organic mineral and 100 ppm for the proportion of organic and inorganic 70:30 ppm.

Abstract

The efficacy of mineral-amino acid complex of Zn,Mn,Cu,Fe and Se for white shrimp, Litopenaeus vannamei, diet compare to inorganic mineral on growth performance, feed utilization and immunity was studied. The treatments were 1) the control diet with contained inorganic minerals of Zn, Mn, Cu, Fe and Se (T1-C1X). 2) treatment diet of the combination of inorganic mineral and organic mineral-amino acid complex70:30 at the same level of control diet Availa Zn, Availa Cu, AvailaMn, Availa-Fe 100and Availa-Se 1000 (T2- Inorg:org 1X) and 3) The sole mineral-amino acid complex Availa Zn, Availa Cu, AvailaMn, Availa-Fe 100 and Availa-Se 10000 at 0.5X (T3-Org 0.5X). The results indicated that there were not significantly different (P>0.05) on the growth performance, feed consumption, feed conversion ratio, Protein efficiency ratio and survival rate. The immune status in term of hemocyte count were significantly increase (P<0.05) in group of shrimp fed mineral-amino acid complex than control.  Drip loss of peel shrimp on 96 hr was low (P<0.05) in group of shrimp fed mineral-amino acid complex than control. Therefore, mineral-amino acid complex of Zn, Mn, Cu,Fe and Se at 0.5X (T3-Org0.5X) exhibited the same growth performance, feed utilization and survival rate as inorganic mineral (T1-C1X) and combination of inorganic and organic mineral-amino acid  complex (T2- Inorg:org 1X). Hence, organic mineral-amino acid complex has the efficacy around 200% of inorganic mineral on shrimp growth performance. Keywords : mineral-amino acid complex ( AvailaZn,Mn,Cu,Fe and AvailaSe); white shrimp; growth performance; immunity; drip loss
