Livestock productivity is strongly influenced by the availability of food, both in quality and quantity. Ruminant livestock feeds are usually forage based diets. But today the availability of land for fodder cultivation is very limited, especially in urban area where most of the pasture land is converted to residential lots. Therefore, in order to feed goats that are kept in urban area, alternative type of forages should be utilized. One such alternative is waste vegetable which is very much available in the market that could be created in the form of wafers.
This study is expected to support the Program of Research, Assessment, Testing, and Agricultural Innovation assembly specifically developed for urban areas. The purpose of this study was to test the utilization of wafer which was made of market vegetable waste as alternative forage, to investigate its effect on goats’ performance. The assessment was divided into two stages, i.e.: wafer manufacturing process with various types of vegetable wastes treatment which was conducted in the BPTP Jakarta laboratory and its application was at the farmer cooperators location who are members of Gapoktan Usaha Terpadu in East Jakarta.
The experimental design used in this trial was the t-test, to compare the wafer as the tested feed to the existing farmers’ technology. The animal used in this study was 8 local male goats in each treatment, which have an average initial body weight of 20 kg. The treatments were native grass + commercial concentrate (farmers’ technology) and wafer of vegetable market waste + concentrate (introduced technology). The ratio between grass or wafer and concentrates supplied was 50:50. The variables measured were daily body weight gain, daily feed consumption, feed conversion and economic analysis.
Results of this experiment showed that the average daily body weight gain was higher when the goats given the wafer (129.76 grams/day) when compared to the control group (73.75 grams/day). The average daily dry matter intake was also higher on the goats given the wafer (294.94 grams/day) compared to the control group (218.17 g/day), It was found that goats consumed the wafer had the lowest feed conversion (2.27 ± 0.11) compared to the control group (2.96 ± 0.62). The benefit derived by applying farmers’ technology and introduced technology were Rp. 175.250 (Gross B/C ratio = 1.18) and Rp. 526.750 (Gross B/C ratio = 1.54).
