Effect of pineapple juice fermented soybean meal on protein dispersibility index and productive performance in nursery pigs

Abstract

The purpose of this study was to study effect of use pineapple juice fermented soybean meal no Protein Dispersibility Index (PDI) and productive performance in nursery pigs. The study was divided into 2 experiments. Experiment 1 was studied the proportion of soybean meal and pineapple juice fermenting ratio and timing. The result revealed that 1 : 2 ratio of soybean meal : pineapple juice fermented for 90 minute gave 12.29 percent PDI. Experiment 2 was studied effect of pineapple juice fermented soybean meal on productive performance of weaning pigs hybrid (LRD). Twenty four weaning pigs, weight average 15 kg were assigned into Completely Randomized Design (CRD) with 3 treatments and 4 replications. Treatment 1 : was control diet, while Treatment 2 : was pineapple juice fermented soybean meal 25 percent instead of soybean meal in diet (FSM25), and Treatment 3 : was pineapple juice fermented soybean meal 75 percent instead of soybean meal in diet (FSM75). The results revealed that average daily gain (ADG) of FSM75 was highest 557.50 g/head/day (P<0.01). Feed Intake was non significant difference (P>0.05). Feed Conversion Ratio (FCR) was 2.19, 1.92 and 1.60 and gain per feed (G/F) was 0.46, 0.53 and 0.62 respectively (P<0.01), as well as feed cost per gain (FCG) was also highly significant difference (P<0.01); 20.46, 18.15 and 15.40 Baht/Kg. respectively.
