Feeding animals for pasture to science

Sporangia herbivorous feeding of pigs with schizophyllum vanilla induced mild fatty degeneration in pig livers, and turbid swelling in liver, kidney and heart muscle. It has been determined that Tricholoma candidum contains triterpenoids, which mainly damage the liver and kidneys of pigs, and can cause cumulative poisoning by long-term feeding. Therefore, the amount of feed should be controlled at 5% to 10% of the diet, preferably with other green feed.

If the fodder beets and fodder are piled up and accumulated for a long time in a humid and hot environment, the nitrates contained in the fodder will be converted into nitrite. After the animals eat a lot of food, they will flow, vomit, foam at the mouth and walk, Muscle tremors, mucous membranes; then rapid heartbeat, difficulty breathing, convulsions, suffocation and death. Therefore, feed fodder should be fed along with the cut, if it should be stored, it should be spread out, keep ventilation, and strictly prevent corrosion.

Synthetic grasses Synthetic grasses contain pyrrolizidine alkaloids, a poison that harms the liver. If fed too much, they can cause cumulative poisoning in the animals and endanger the human liver. The amount of fed grass should be controlled at 20% to 25% of the diet, and it is best to plant and cross feed with other pastures.

Sudangrass Sudangrass is a sorghum genus. Its stems and leaves contain hydrocyanic acid, which is more toxic and can kill livestock. Immediately after the onset of livestock, 1 g of sodium nitrite, 2.5 g of sodium thiosulfate, and 50 ml of water for injection should be injected intravenously. In addition, corn seedlings, sorghum seedlings, and pumpkin pods also contain high levels of cyanogenic glycosides. After the animals feed, cyanogenic glycosides are also converted to hydrocyanic acid. Therefore, when using these crops as feed, it is best to turn it into silage, or after harvesting and drying, so that the content of toxins will be reduced and will not cause animal poisoning.

Festuca arundinacea is suitable for cattle and sheep, but it contains pyrrolidine. For example, in the late spring and early summer, when single-fed fescue is used to feed cattle, the cow will experience poisoning such as dry skin, diarrhea, and weight loss. In the long-term feeding of sheep, the weight gain of the sheep is not ideal and should be fed together with other pastures.
