Sweeteners are mainly sugar and saccharin, and sugar is mostly used for piglets. The amount should not be too high, generally 2% to 3%, otherwise it may cause diarrhea in piglets; fattening pig feeds can use saccharin, and tests have shown that each ton of feed is added. 50 grams of saccharin can increase the daily gain of pigs by more than 6% and feed consumption by 4%.
The flavoring agent pig is more sensitive to the aroma in the feed, so some food essences can be used as feed additives, and 200-500 grams per ton of feed is added, which has a better effect. Grease is also a flavoring agent. Adding 2% to 3% of piglet feed can improve 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. It can also improve the palatability of feed, increase appetite, help digestion and absorption of nutrients, and improve feed utilization. The amount added in the pig diet is 0.25% to 0.35%, and excess 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%.
