Prevention of Potato poisoning

Potato is rich in soluble carbohydrates and has good digestibility for all kinds of livestock, and the nutrition of raw and cooked feeding is basically similar. However, the stems, leaves and tuber kernels of potatoes all contain toxic substances, so feeding should be more cautious.

Potatoes contain more non-protein nitrogen, accounting for about half of crude protein, among which there is a nitrogen-containing substance called solanine, which is toxic. The content of this substance is the highest when the tuber is immature and germinated, and it is generally the most in the turquoise skin and bud eyes of the stem, and there are more nitrates in the stems and leaves, which will cause gastroenteritis and poisoning death of livestock after collection and feeding. Sows will give birth to abnormal piglets or stillbirths after feeding.

In order to prevent poisoning caused by potatoes in the process of feeding livestock, potatoes should be stored in a dry, cool, sun-free place to prevent sprouting and turning green. If it has sprouted and turned green, you should pay attention to remove the buds and green parts before feeding, dig around the bud eyes, and then cook to reduce the toxicity, and the residual water after cooking should be discarded. In addition, potatoes should be fed to livestock with other feeds, controlled at about 25% of the diet, and pregnant sows had better not be fed. When normal potatoes are fed to livestock, it is best not to exceed 50%.

When the stems and leaves of potatoes are to be boiled over high heat, it is best not to cover the pot cover in the process of cooking to prevent the formation of nitrites. It can also be mixed with other silage and then fed.
