| In this study, the Wuliangsuhai deposit plant's nutritional values were investigated by nutritive analysis, digestion, feeding and slaughter trials. It studied effects of deposit plants on the reproductive performance of the brood swine. The deposition of trace elements: iron, iodine, Manganese and fluorine in some inner organs was studied. It assessed the nutritional effect of the deposit plants on pigs synthesisly. 1.The content of rude protein is 9.51%,12.95% in the original and selected deposit plants respectively .The plants consist of balanced amino acids , abundent mineral elements and vitamine .The content of Fe ,I, Mn, F is1184.6mg/kg,188.411 mg/kg,2373.7 mg/kg,143.22 mg/kg。 2.The content of nutrient is highest in the selected and the lowest in the watered. It told us it is unnecessary to water the plants. 3.The growing swine diet supplemented 3% plants improved the digestibility daily gain, dressing percentage and economic profit .The brooding pig diet supplemented 5%plant is most suitable in each group. 4.The diet supplemented 3%,7%,11%plants improved the deposition of Fe, I, Mn, F in inner organs, but it do no harm to swine.5.The content of Fe, I, Mn, F in tested swine flesh is in normal range. It is safe for us to eat...
