ABSTRACT

Native animals are regarded as essential component of most agricultural rural settings in the Philippines. Amorphophallus paneoniifolius L. can be used as alternative source of feed sourced for animals, however its application is limited due to the concentration of oxalate compound and low crude protein level when it is not properly prepared as feed for animal. One of the methods to be used to make Pongapong to its optimum potentials as feed source is fermentation with oxalolytic bacteria, such as Bacillus subtilis, which produces the oxalate decarboxylase enzyme that degrade the oxalate compound to boost the nutritional value of pongapong. This study is to determine the growth performance of native pig supplemented with ensiled pongapong as feed supplement to swine. Specifically, to determine the effect of ensiled pongapong on the body weight-gain in weight, growth increment, feed conversion efficiency and feed conversion ratio on Philippine native pigs; determine the best level of silage pongapong to growth of Philippine Native pigs; and determine the economics of fermented pongapong as feed supplement for native pigs. “The Complete Randomized Design (CRD) was utilized in the study. The treatments were follows:T1 —Formulated feeds Formulated feeds + 25% silage AC ,T3=500/0 Formulated feeds 50% silage AC, Formulated feeds + 75% silage AC, T Pure ensiled AC. Based on the analysis of variance shows insignificant among the treatments as to the initial weight, feed conversion efficiency and growth rate. Also, there are significant differences in the body weight, gain weight and feed conversion ration while it shows highly significant feed consumption throughout the duration of the study. Thus, 75% formulated feeds and 25% fermented Pongapong and 50% Formulated feeds + 50% fermented Pongapong results to best growth. It demonstrates that feeding native pigs with formulated feed including fermented pongapong was employed as an alternative diet that is potentially cost effective and useful in native pig production in the province. This information could help growers reduce feed costs.
