Simple Methods for Fattening Pigs: Are Fattening Agents Effective?

Abstract: You can add 2% mugwort powder, 80% paulownia flowers, 20% knotgrass, 15g of glauber's salt, and 25-50g of negundo chastetree fruit to the daily ration. You can also mix 1 part sesame, 3 parts roasted soybeans, and 1 part shelled roasted castor beans, grind them into powder, and mix them into the feed. Generally, when pigs weigh 30-50kg, using Baijin Peptide fattening agent can increase daily weight gain by 15%; if used throughout the entire fattening period, it can increase weight by more than 20 jin and allow the pigs to be sent to market 15-20 days earlier.

I. Simple Methods for Fattening Pigs

1. Add mugwort powder

Mugwort leaves contain aromatic oil, so they can promote blood circulation, enhance metabolism, improve meat quality, and have antibacterial effects. Generally, adding 2% mugwort powder to the pig's daily ration can increase the average daily weight gain by 5%-8% and raise feed efficiency by 7.5%-12.3%. Note that the fuzz on the mugwort leaves needs to be removed during processing, and sufficient drinking water must be provided after feeding.

2. Add paulownia flowers and knotgrass

(1) Paulownia flowers have the effects of clearing heat, strengthening the stomach, and detoxifying. Knotgrass, also known as spotted knotweed, has diuretic and dampness-removing effects. Adding this grass in summer and autumn helps pigs prevent heatstroke.

(2) Paulownia flowers contain substances that promote body growth. Generally, the leaves, flower buds, and fruits of paulownia can all be used as feed. Pigs like to eat them, and they are not prone to getting sick after eating them.

(3) You can sun-dry and crush 80% paulownia flowers and 20% knotgrass, mix them together, and feed them. They can be mixed into the feed 3 times a day, 1 tablespoon each time, especially suitable for pigs weighing more than 40 kg.

3. Add glauber's salt

(1) Adding an appropriate amount of glauber's salt to a complete compound feed can help promote an additional 30% weight gain in pigs.

(2) In summer and autumn, live pigs are prone to dry and hard stools. At this time, adding glauber's salt can purge heat and remove stagnation, prevent and treat constipation, and help treat chronic indigestion.

(3) Generally, when the feed lacks limiting sulfur-containing amino acids, adding glauber's salt can accelerate protein synthesis in the pig's body, thereby achieving a fattening effect. The daily amount of glauber's salt added per pig should not exceed 15 grams, and during this period it should be determined according to the condition of dry and hard stools.

4. Add negundo chastetree fruit

Negundo chastetree fruit is rich in fat, so it is a good feed for fattening and putting on weight. Take 25-50 grams of negundo chastetree fruit per pig per day, fry until yellow, grind into powder, and mix into the feed. Feed continuously for 15-30 days.

5. Add sesame-bean agent

During this period, take 1 part sesame, 3 parts roasted soybeans, and 1 part shelled roasted castor beans, mix and grind into powder, and mix into the feed. After continuous feeding for 1 month, the pigs will be fat and full of meat.

II. Are Fattening Agents Effective for Pigs?

1. Generally, using the pig-specific Baijin Peptide fattening agent has a relatively good effect. After 3 days of use, the daily feed intake can increase by 15%; after 5 days of use, digestion and absorption are better, the feed residue decreases by 15%, and the feces are noticeably reduced; after 7 days of use, the pig's coat and skin are shiny; after 15 days of use, the pig's body shape is noticeably improved, achieving the effect of a double-muscled back and double-muscled rump.

2. When used at a pig weight of 30-50 kg, it can lengthen the skeleton by 7-10 cm, increase daily weight gain by 15%, and reduce the feed-to-weight ratio by 6.25%. If used throughout the entire fattening period, it can increase weight by more than 20 jin and allow the pigs to be sent to market 15-20 days earlier.
