河蚌在动物中属软体动物门,瓣鳃纲,真瓣鳃目,蚌科。它广泛分布在江河、水库、塘堰的缓流浅水区和稻田中。适宜在 PH 值为6～8之间的水域生活。我县各河流的 PH 值均在6.5～7.5之间,年平均气温在18℃左右,非常有利于河蚌的生长。凉河6队有12名社员,1984年6月,仅在本队河段内,一天就捕捞河蚌9600多斤。据分析,鲜蚌肉含10%±0.4粗蛋白质,蚌肉粉含45～51%粗蛋白质,氨基酸的含量很全面。试验证明,在育肥仔鸡日粮中添加10%的蚌肉,可以提高增重39%,降低饲料消耗40%。在产蛋鸡日粮中添加10%的蚌肉,能显
River clam in the animal is a mollusc door, flap gill class, true flap gill, clam families. It is widely distributed in rivers, reservoirs, ponds and slow shallow flow of paddy fields. Suitable for PH value of 6 to 8 between the waters of life. PH value of rivers in our county are between 6.5 to 7.5, the annual average temperature at about 18 ℃, is very conducive to the growth of mussel. There are 12 members of the Lianghe 6 team. In June 1984, only 9,500 kilos of mussel were caught in a day in the team’s river section. According to the analysis, fresh clam meat contains 10% ± 0.4 crude protein, mussel meal contains 45 ~ 51% crude protein, amino acid content is very comprehensive. Experiments show that in the fattening chickens diet add 10% clam meat, can increase weight gain 39%, reduce feed consumption 40%. In laying hens diet add 10% clam meat, can be significant
