In recent years, various innovative feeding methods have been explored in pig farming around the world to improve growth rates, meat quality, and overall efficiency. These techniques not only enhance productivity but also contribute to better animal welfare and consumer satisfaction.
1. **Adding Bentonite to Feed**
A Russian pig farm experimented with adding 1% bentonite to the feed of finishing pigs. The results were impressive: daily weight gain increased by 3%, while the survival rate and appetite improved significantly. Additionally, the meat became more flavorful, making it a popular choice among consumers.
2. **Feeding Pigs with Tea**
Japanese experts came up with an unusual idea — giving pigs tea. They believed that just as tea benefits human health, it might also improve the quality of pork. After conducting experiments, they found that pigs raised with tea had better-tasting meat. This led to the creation of the "Tea US Dolphin" brand, which promotes the "Tea American Dolphin" feeding program. Pork treated with tea leaves became highly sought after in Tokyo and other cities.
3. **Juice Wine in Drinking Water**
An Australian pig farm introduced a small amount of juice wine into the drinking water of pigs. The wine helped kill harmful bacteria in the sewage system, reducing the occurrence of cholera and intestinal diseases. This led to lower mortality rates among piglets and faster bone development in growing pigs.
4. **Feeding Sugar Beets**
A British pig farm successfully incorporated sugar beets into pig feed. In a trial involving 400 hybrid pigs, 15% beet powder was added to the feed of pigs weighing between 13 and 32 kg, and 20% during the finishing phase. This improved feed conversion rates, shortened the slaughter period, and enhanced pork quality, leading to significant economic gains. Many farms now follow this practice.
5. **Adding Citric Acid to Feed**
U.S. researchers added 30 grams of citric acid per kilogram of feed for weaned piglets aged 5 to 10 kg. This not only improved feed palatability and nutrient absorption but also increased feed conversion efficiency and daily weight gain. The average daily gain rose from 189 grams to 216 grams, showing a clear improvement in growth performance.
6. **Playing Recording of Sow Sounds**
At a domestic livestock testing site, a recording machine was used to play the sounds of nursing sows periodically. This helped reduce the time between suckling sessions and prevented piglets from being crushed. The test showed that piglets exposed to the recordings had an average weaning weight of 7 kg, compared to 6.2 kg in the control group. Additionally, none of the recorded piglets suffered from crushing injuries, while 8.7% of the control group died due to this issue.
These unique feeding strategies demonstrate how creative approaches can lead to better outcomes in pig farming, benefiting both producers and consumers.
