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