In recent years, innovative feeding practices have been adopted by pig farmers around the world to improve pig health, growth rates, and meat quality. These methods are not only cost-effective but also contribute to better animal welfare and more sustainable farming. Here are some unique and effective strategies being used in different countries:
1. **Adding Bentonite to Feed**
In a Russian pig farm, 1% bentonite is mixed into the feed of finishing pigs. This practice has shown significant benefits: it increases daily weight gain by 3%, improves survival rates, enhances appetite, and even makes the meat more flavorful. Bentonite, a natural clay, acts as a binding agent and helps with digestion.
2. **Offering Tea to Pigs**
Japanese pig experts have taken an unusual approach by giving pigs tea to drink. The idea is that if tea is beneficial for humans, it might also enhance the quality of pork. Experiments showed that pigs raised with tea had better-tasting meat. This led to the creation of the "Tea US Dolphin" brand, which promotes tea-based feeding programs to produce healthier and more delicious pork.
3. **Using Juice Wine in Drinking Water**
An Australian pig farm has introduced a small amount of juice wine into the pigs' drinking water. This helps eliminate harmful bacteria in the water, reducing the risk of diseases like cholera and intestinal infections. It also supports faster bone development and lowers piglet mortality rates, making this a practical and effective addition to their routine.
4. **Feeding Sugar Beets**
A British pig farm incorporated sugar beets into the diet of growing pigs. In a trial involving 400 hybrid pigs, 15% beet powder was added to the feed for pigs weighing between 13 and 32 kg, while 20% was used for those over 32 kg during the finishing stage. This improved feed conversion rates, shortened the slaughter period, and enhanced meat quality, leading to better economic returns for the farm.
5. **Adding Citric Acid to Feed**
U.S. researchers found that adding 30 grams of citric acid per kilogram of feed for weaned piglets (5–10 kg) significantly improved feed palatability and nutrient absorption. This boosted daily weight gain from 189 grams to 216 grams, helping piglets grow faster and healthier.
6. **Playing Recorded Sow Calls**
A domestic animal husbandry research station tested the effect of playing recorded sow calls to stimulate piglets. This reduced the time between suckling sessions and prevented crushing incidents. The results 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 group suffered from crushing injuries, while 8.7% of the control group did.
These unconventional methods highlight how creative approaches can lead to better outcomes in pig farming, benefiting both animals and producers. As the industry continues to evolve, such innovations may become more widely adopted.
