Abstract

A 40-day feeding trial was conducted to evaluate the nutrient digestibility of Madre de Agua (Trichanthera gigantea) leaves and the potential of using fresh Madre de Agua (MdA) leaves as supplement for grower-finisher pigs. A total of six pigs were randomly distributed into two treatments with three replicates per treatment following randomized complete block design with initial weight as blocking factor. For the digestibility trial, difference method was used to determine the nutrient digestibility of MdA leaves. The dietary treatments were 100% mixed feeds and combination of 90% mixed feeds and 10% MdA leaves. For the growth performance experiment, pigs in treatment 1 were fed 100% mixed feeds while pigs in treatment 2 were offered fresh MdA leaves in addition to the mixed feeds. On a dry matter basis, the MdA leaves that were used contained 18.07% ash, 15.80% crude protein, 1.15% crude fat, 15.42% crude fiber, 4.70% calcium and 0.32% total phosphorus. It has 6.35% digestible crude protein, 8.90% digestible ash, and 1668 kcal DE/kg. Based on the results of the growth experiment, no differences were observed on the initial and final body weight, average daily gain, and feed efficiency between the treatments at both grower and finisher stages. Economic analysis showed that feeding fresh MdA leaves at grower stage resulted to lower income over feed cost and lesser cost efficiency compared to the control group. However, at finisher stage, pigs fed with fresh MdA leaves had higher income over feed cost and better cost efficiency than the control group. This was attributed to the lower feed consumption of pigs fed MdA leaves but same body weight gain in comparison to the control group. In general, provision of fresh MdA leaves to grower-finisher pigs, in addition to the mixed feeds, had no negative effect on the growth performance of the pigs and is more economical than providing mixed feeds alone at finisher stage.
