1. Ye Ziye leaves are rich in nutrients and have antibiotic effects on pigs. In Japan, the addition of 2% wormwood powder to pig diets can reduce feed consumption by 7%-12%, except for the increase of 5%-10% in daily growth.
2. Feeding zeolite powder method Japan adds 5% zeolite powder to feed the pig. Each additional kg of zeolite powder can increase the weight of the pig by 4 kg, saving nearly 1/4 of the feed and reducing the bronchitis and stomach of the pig. Enteritis, rickets, and diarrhea in piglets. Used to feed sows, but also speed up the growth of piglets.
3. Feeding the rare earth method In the United States, adding 2.5 grams of rare earth to 1 kilogram of feed for pigs can increase pig weight by 20-45.
4. Feeding saccharin or baking soda by adding 0.05g saccharin per kilogram of feed can greatly increase the feed intake of the pigs, increase the daily gain by 7%, and the feed consumption and cost decrease by 4.8% for each 100kg weight gain. And 3.5%. Pigs fed saccharine can be first dissolved in water and then fed with spices. In the absence of a supply of lysine, baking soda can be used instead, which is not only less costly but also can receive the same weight gain. The amount of baking soda used: Pigs were fed 10 grams a day, middle pigs were fed 20 grams a day, and big pigs were fed 30 grams a day.
5. Feeding the fat and oil France study in Japan, in the feed of weaned piglets, add 50% of soybean oil and 50% of coconut oil, and add 2% to 5% of the diet per day in the feed. The weight gain is higher than that of the control group. (ie not fat-fed) 14.5% higher.
6. The main experiment in Germany, fed with flavomycin or citric acid method, piglet weight 30-35 mg, daily gain can be increased by 5%. Finishing pigs add 5 mg per kilogram of feed.
According to the latest tests, adding some substances in the pig's feed can increase the pig's weight and reduce the consumption of feed. Professional pig raising techniques can increase the weight of the pig.
