Sweeteners are mainly sugar and saccharin. Sugar is used in piglets. The dosage should not be too high, generally 2%~3%. Otherwise, it is easy to cause piglet diarrhea. Sweetening pig feed can use saccharin. Tests have shown that adding 50 grams of saccharin per ton of feed can increase the daily gain of pigs by more than 6% and the feed consumption by 4%.
Flavored pigs are more sensitive to the aroma of the feed, and the addition of aroma has a better effect. Some edible flavors such as milky flavor, spicy flavor, and the like can be used. Adding 200 g to 500 g per ton of feed has a good effect. Grease is also a kind of flavoring agent. Adding 2%~3% in piglet feed can increase feed conversion rate and increase weight gain.
The salty agent is mainly sodium chloride (salt), which plays an important role in regulating the acid-base balance of body fluids, maintaining the balance of osmotic pressure between cells and blood, stimulating saliva secretion, participating in gastric acid formation, and promoting digestive enzyme activities. As a flavoring agent, salt can improve the palatability of feed, enhance appetite, help digestion and absorption of nutrients, and improve feed utilization. The amount added in the pig diet is 0.25% to 0.35%. If excessive, it will cause salt poisoning.
The savory agent is mainly MSG, which is widely used in pig feed abroad. Appropriate addition can significantly increase the appetite of pigs and promote growth. Generally, 200 grams per ton of feed can increase the feed intake, shorten the fattening period, and increase the daily gain by about 5%.
