Dietary Supplementation of Poly-β-Hydroxybutyrate on the Growth, Digestive Enzymes Activity and Body Composition of Rainbow Trout (Onchorynchus mykiss)

Abstract

Poly-β- hydroxybutyrate (PHB) is short chain fatty acids and accumulated by many of microbes and utilizes as source of energy and carbon, the present study is planned to check the effect of dietary supplementation of poly-β-hydroxybutyrate on the growth, gut enzymatic activity and body composition of Rainbow Trout (Onchorynchus mykiss). The fish were fed with four types of feeds containing different levels of poly-β-hydroxybutyrate (PHB1%, PHB2%, PHB3%) and a control (PHB0%) feed without addition of any agent three times a day at feeding rate of 3% of the fish wet body weight. The results of current study revealed that dietary supplementation of poly-β-hydroxybutyrate increased the growth performance, improves body composition and immune response in rainbow trout (Onchorynchus mykiss) fingerlings. Overall growth performance was found satisfactory in all the treatment groups with significant difference. PHB1 group showed significant difference with the other entire group regarding FCR (1.23 ± 0.01), %weight gain (503.92 ± 14.02), SGR (3.10 ± 0.04) and weight gain (26.15 ± 0.92). There was significant difference observed in PHB1 group for crude protein, crude lipid. It was observed that PHB groups showed significantly lower value for crude fat and significantly higher value of crude protein as compare to control (PHB0) group. There was a non-significant differences present between PHB fed group and control group for fatty acid analysis There was a significant differences present between PHB fed group and control group for digestive enzymes activity. Specifically PHB1 showed significant difference with all other treatment groups. There was a significant differences present between PHB fed group and control group for hematological studied.PHB2 showed significant difference with all other treatment groups. In conclusion, the current study indicated that PHB is a valuable dietary supplement for improving growth performance, body composition and immune responses of rainbow trout fingerlings.
