The quality of feed is directly related to the success or failure of breeding. There is a wide variety of feeds for turtle culture, and the quality is uneven. How to distinguish the quality of soft-shelled turtle feed? Whether it is the feed of seedlings, seeds, and clams, when the soft-shelled turtle feeds, the excrement in the normal culture environment will be excreted due to the quality of the feed. Different and different.
1. Observe the shape of the feces discharged on the day
Some turtles excrete very long excrement, and some even adhere to the anus, and others are curled. This shows that there is an excessive proportion of the feed that is not easily digested and absorbed by turtles, such as some plant proteins. In particular, plant proteins that have not been activated. The second is the excessive proportion of feed ingredients containing more carbohydrates, such as ordinary raw starch, flour and so on. When the soft-shelled turtle feed is eaten by soft-shelled turtles, the excreted manure is very short and will not stick to the anus of the soft-shelled turtle.
2, see the color of feces
Normal feces, such as high-quality animal feed, the color of the feces should be grayish green or grayish white. If the proportion of starch or vegetable protein feed is too high, the feces will be milky white. If there are additives such as yellow pigment in the feed, the feces will be pale yellow.
3, look at the color
In some places where feed is fed underwater and the excrement is difficult to see, water color discrimination can be seen because faeces are the main factor that directly changes the color of water. Normally, the normal color of Dianchi Lake is light green, and if it is normal high-quality feed, the color of the water that is contaminated by the feces is brown first, followed by black when severe, and there is an unpleasant odor. However, in some industrialized greenhouses, the pool water is milky white or light yellow and has some smell or fermented taste. This is also caused by the decomposition of the fecal matter discharged after eating the non-digestible feed, and should be noticed.
