Additional of crocot flour (Portulaca oleracea l.) and Mannanoligosaccharides (MOS) in feed for improving growth performance windu shrimp (Penaeus monodon)

Abstract

This study aims to determine the effect of giving purslane flour and MOS to feed on increasing growth performance in Windu shrimp (Paneus monodon). The research was carried out at the Balai Perikanan Budidaya Air Payau Ujung Batee (BPBAP) in Ujung Batee. This study was conducted using a Complete Randomized Design (CRD) method with 4 treatments used, namely A (control), B (30 g/kg purslane flour and 10 g/kg MOS), C (40 g/kg purslane flour and 10 g/kg MOS), and D (50 g/kg purslane flour and 10 g/kg MOS). The results showed that the addition of 40 g/kg purslane flour and 10 g/kg MOS resulted in an absolute weight growth of 0.60±0.05 grams, a specific growth rate 16.00±0.24% per day, an absolute length growth of 4.33±0.06 cm, a feed conversion ratio of 0.52±0.03, feed efficiency of 192.08±12.21%, moulting frequency of 1.50 times per head, and a survival rate of 93.20±9.33%.
