According to international research and experiments conducted in Japan, the United States, and Germany, it has been proven that adding specific substances to pig feed can significantly improve growth rates while reducing overall feed consumption. These methods have been widely tested and applied in different regions, showing promising results for farmers looking to optimize their livestock production.
One such method is the use of leaf-based feed. Leaves are rich in nutrients and offer disease-resistant benefits to pigs. For example, in Japan, adding 2% wormwood powder to pig diets has been shown to reduce feed consumption by 7%-12%, while also increasing daily weight gain by 5%-10%. This method not only improves efficiency but also supports better health in the animals.
Another effective technique involves the use of zeolite powder. In Japan, adding 5% zeolite powder to the feed has resulted in a 4 kg increase in pig weight per 1 kg of zeolite used. Additionally, this method helps save nearly 25% of feed and reduces the occurrence of diseases like bronchitis, gastroenteritis, rickets, and diarrhea in piglets. It also benefits sows by accelerating the growth of their offspring.
In the U.S., the use of rare earth elements in feed has demonstrated impressive results. Adding 2.5 grams of rare earth per kilogram of feed can lead to an additional 20-45 kg of weight gain in pigs and improve feed utilization by 3%-12%. This method is especially useful for improving the overall performance of the herd.
Saccharin or baking soda can also be added to feed to enhance pig growth. Adding 0.05g of saccharin per kilogram of feed increases feed intake and daily weight gain by up to 7%. Pigs fed with saccharin should first be dissolved in water before being mixed with spices. If lysine is unavailable, baking soda can be used as an alternative. It’s more cost-effective and provides similar weight gain results. The recommended dosage is 10g for small pigs, 20g for medium pigs, and 30g for large pigs per day.
The fat feeding method has also proven beneficial. In Japan, a 50% blend of soybean oil and coconut oil was added to the diets of weaned piglets at a rate of 2%-5% of the total diet. This led to a 14.5% higher weight gain compared to the control group, which received no fat supplements.
Finally, the use of flavomycin or citric acid has been tested in Germany. Starting from 30-35 kg, adding 20 mg of flavomycin per kilogram of feed increased daily weight gain by 5%. For finishing pigs, 5 mg per kilogram of feed was used. In the UK, adding 30 grams of citric acid per kilogram of feed for weaned pigs weighing 5-10 kg resulted in a 30%-35% increase in weight gain.
These methods highlight how scientifically backed feed additives can significantly boost pig productivity while reducing costs and improving animal health. Farmers around the world are increasingly adopting these techniques to achieve better results in their operations.
