The addition of papaya leaf powder (Carica papaya L.) in feed to increase digestibility of milkfish fry (Chanos chanos)

Abstract

The purpose of this study was to see the effect of adding papaya leaf powder with different doses to increase the growth rate and digestibility of milkfish fry (Chanos chanos). The method in this study used a completely randomized design (RAL) with 4 treatments each with 5 repetitions. The treatment used in this study was feed without the addition of papaya leaf powder or control treatment (A), the addition of papaya leaf powder 2% (B), 2.5% (C) and 3% (D). The feed that has been made is added with chromium which functions as an indicator of digestibility. Feeding is carried out for 40 days. The results showed that the addition of papaya leaf powder had a significant effect (P<0.05) on increasing the specific growth rate, growth in absolute length and absolute weight, FCR and digestibility of milkfish fry, but had no significant effect (P>0.05) on survival rate (SR). The best results in this study were shown in treatment D (with the addition of 3%/kg papaya leaf powder to the feed) showed a specific growth rate 0.93%, absolute length and absolute weight growth respectively 1.12 cm and 0.37 g, FCR 1.86%, and digestibility were 77.7%.
