Pig raising weight gain ten kinds of feeding methods

1. Calcium formate supplementation: Adding 1.5 grams of calcium formate to piglets during the first few weeks after weaning can boost their growth rate by over 12%, improve feed conversion by 4%, and reduce the occurrence of diseases in young pigs. This method helps ensure healthier and faster-growing piglets, especially during the critical early stages. 2. Enhancing sow productivity: Starting from the third day post-weaning, adding 200 mg of vitamin E and 400 mg of carrots to the sow's diet can significantly improve her reproductive performance. When the sow comes into estrus, reduce these amounts to 50% and continue feeding until day 21 of pregnancy. This approach increases litter size by 21.9%, strengthens both sows and piglets, and improves piglet survival rates. 3. Using baking soda for weight gain: Adding baking soda to pig feed that is deficient in lysine can help compensate for this deficiency. It also supports better digestion and absorption of crude fiber, leading to improved body condition and faster weight gain in pigs. 4. Copper supplementation for growth: Introducing small amounts of copper during the fattening period can enhance weight gain and protect pigs from certain pathogens. When combined with antibiotics in feed, copper can increase daily weight gain by 6.7% and improve feed efficiency by 2% to 5%. This is a cost-effective way to boost productivity. 5. Saccharin for increased weight gain: Adding 0.05 grams of saccharin per kilogram of compound feed can stimulate appetite and improve feed intake. This leads to a 7% increase in daily weight gain. For every 100 kilograms of weight gained, feed consumption and costs decrease by 4.8% and 3.5%, respectively. 6. Yellow pigment (flavomycin) supplementation: Once pigs reach 35 kg, adding yellow pigment to their feed can improve weight gain by 7% and increase feed conversion by 5%. The recommended dosage is 20 mg/kg for piglets, 50 mg/kg for finishing pigs, and 250 mg/kg for mineral feed. 7. Citric acid for better feed utilization: Adding 30 grams of citric acid per kilogram of feed enhances palatability, improves nutrient absorption, and boosts feed conversion. This results in an increase in daily weight gain from 189 grams to 216 grams. This method is particularly effective for weaned pigs weighing between 5 and 10 kg. 8. Changing pens to stimulate growth: Moving fattening pigs to new pens once a month can stimulate their appetite and promote faster growth. However, it’s important to keep the pen size and layout consistent and avoid mixing pigs from different groups to prevent stress and aggression. 9. Oxygenated soft drinks for weaned pigs: Giving weaned pigs oxygenated soft drinks once every five days can help them gain 200-250 grams per day. These drinks are made by dissolving oxygen into water, typically at a ratio of 1 liter of oxygen to 1 liter of water. Adding some nutrients or fertilizers to the drink can further enhance its effectiveness. 10. Vitamin C for better semen quality: Adding 1-4 grams of vitamin C to boar feed daily can significantly improve semen quality. Additionally, giving sows 1 gram of vitamin C per day during the first week of pregnancy can reduce umbilical cord bleeding and piglet mortality, improving overall reproductive success.
