Effect of Using Mustard and Kitchen Dry Copra Meal Substituted for Soybean Meal in Finishing Pig Feed

Abstract

The purpose of this study was to investigate the effect of using mustard and kitchen dry copra meal substituted for soybean meal in finishing pig feed. The study employed 12 pigs of 3-way cross-bred pigs (Large White x Landrace x Duroc) of the same litter with mixed genders with 53 kilograms of the average initial body weight. They were arranged by Completely Randomized Design (CRD) experiment and divided into 3 treatments (groups) of 2 replications. Each group was randomly fed by one of the experimental diet formulae as fallows; Group 1: soybean meal diet, Group 2: the 15% substituted level of mustard meal for soybean meal diet, and Group 3: the 15% substituted level of kitchen dry copra meal for soybean meal diet. The duration test was 10 weeks with an average of pig body weight at 100 kilograms.

The results showed that the productive performance (the growth rate and feed efficiency) of Group 2 was the highest, followed by Group 1 and Group 3 with the significant difference (p>0.05). It can be concluded that the 15% mustard meal can be substituted for soybean meal diet causing the highest productive performance and the lowest cost. However, using 15% of kitchen dry copra meal substituted for soybean meal diet tended to reduce the productive performance due to spongy feed causing lower pig feed consumption.
