Abstract
The study was conducted to characterize the flora and fauna found in a 75 m2 paddy field enclosed with a mesh net fence to document the feed preferences of Itik Pinas while grazing. A total of 18 laying ducks (45 weeks old) were used in the study. The ducks were starved for 12 hours and brought to paddock to graze for 3 hours. They were sacrificed after grazing and their digestive tracts were dissected. Flora and fauna present in the gut were identified by a biologist. sample of flora and fauna consumed by the ducks were brought to the laboratory for proximate, calcium, phosphorus, energy and cadmium analysis. A 1 kg of soil sample from the field was also brought to laboratory for cadmium analysis.
The results showed that flora and fauna in the area were: rice, water spinach, jungle rice, sandbur, golden apple snails, caterpillar, and common lizard during rainy season. The most preferred and consumed flora of ducks were rice seeds, water spinach, rice hays and jungle rice. In fauna, golden apple snails were the most preferred by ducks. the proximate and mineral content of each materials consumed by the ducks were the following: water spinach had 13.29% mositure, 13.03% ash, 28.70% crude protein (CP), 19.66% crude fiber (CF), 1.32% fat, 23.9% nitrogen free extract (NFE), 0.74% Ca, 0.80% P and 3,012 keal/kg gross energy (GE); Rice seeds had 10.55% moisture, 4.82% ash, 6.44% crude protein (CP), 11.13% crude fiber (CF), 2.02% fat, 65.04% nitrogen free extract (NFE), 0.20% Ca, 0.25%P and 3,4486 keal/kg gross energy (GE); Jungle rice had 7.58% moisture, 1370% ash, 11.39% crude protein (CP), 28.10% crude fiber (CF), 1.34% fat, 37.89% mitrogen free extract (NFE), 0.59% Ca, 0.32% P, and 3,216 kcal/kg gross energy (GE); Rice hays had 7.81% mositure, 13.52% ash, 17.76% crude protein (CP), 20.88% crude fiber (CF), 2.51% fat, 37.52% nitrogen free-extract (NFE), 041% Ca, 0.33%P, and 3,273 kcal/kg gross energy (GE); and Golden apple snail had 3.47% mositure, 78.86% ash, 15.16% crude protein (CP), 2.84% crude fiber (CF), 0.38% fat, 0.00% nitrogen free extract (NFE), 29.50% Ca, 057% P, and 3,477 kcal/kg gross energy (GE). Also, cadmium content of samples were: water spinach at 0.10 mg/kg, rice seeds at 0.55 mg/kg, golden apple snail at 1.21 mg/kg and insoil at 0.09 mg/kg. Levels of cadmium in flora and fauna and soil samples were below the maxiumu toxicity value and safe for consumption of Itik-Pinas.
