With the increase of pig raising cost, how to save feed has become the most concerned problem of farmers. Here are ten ways to save feed for pigs for your reference.
1. 提高混合的猪。杂交猪长得很快。耗材少，效率高。根据试验，饲喂杂交一代猪，日增重可增加30%，可节省40%的饲料，发病率可提高60% ~ 80%。
1. Improve the mix of pigs. Hybrid Pigs grow very fast. Less consumables and high efficiency. According to the experiment, the daily gain of feeding the Hybrid Pigs increased by 30%, and 40% of the feed was saved, the incidence rate increased by 60% to 80%.
2. 在正确的时间繁殖。断奶仔猪60 ~ 40 ~ 45天可促进母猪早发情、早育，缩短空期，节省饲料。
2. Breed at the right time. Weaning piglets for 60-40-45 days can promote oestrus and early childbearing of sows, shorten the empty period and save feed.
3. castration. Compared with the traditional 60 day castration, the body weight of 30 day old boar and 40 day old sow increased by 15%, and the fattening period shortened by 20 days. Save 20% of the feed.
4. 清除bug。猪被虫食欲旺盛后生长迅速，日增重可提高20 ~ 30%，节省饲料10%以上。
4. Clear the bug. The growth of pigs is rapid after they have a strong appetite. The daily gain can be increased by 20-30% and the feed can be saved by more than 10%.
5. 练习人工繁殖。这样，猪的运动小，能耗少，材料可节省8% ~ 10%。
5. Practice artificial reproduction. In this way, the exercise of pigs is small, energy consumption is low, and materials can be saved by 8% - 10%.
6. 实践保护喂养。在夏季，猪圈前的厝沙防暑棚，为防止中暑，每增重1公斤可节省精料0.6公斤。冬季和春季采用暖棚饲养，可避免饲料浪费。实验结果表明，春早6时暖棚温度为8.36℃，春早14时为12℃，对照蛆分别对应3.11℃和9.37℃，试验组比对照组每穗谷粒6.08 kg。另有数据表明，冬季猪圈干草垫料可降低猪的能量消耗。当温度为3℃时，草席的日重比草席高90克。
6. Practice protective feeding. In summer, in order to prevent heatstroke, 0.6kg of refined material can be saved for every 1kg of weight gain in the Cuosha heatstroke shelter in front of the pigsty. In winter and spring, it can avoid the waste of feed. The results showed that the greenhouse temperature was 8.36 ℃ at 6:00 am in spring, and 12 ℃ at 14:00 am in spring. The control maggots corresponded to 3.11 ℃ and 9.37 ℃ respectively. Other data show that the energy consumption of pigs can be reduced by using the hay pad in winter. When the temperature is 3 ℃, the daily weight of straw mat is 90g higher than that of straw mat.
7. Change to mature feed. Feed pigs raw feed. It is not only convenient to feed, but also time-saving and labor-saving. And good palatability, conducive to the preservation of nutrition and improve the utilization rate of feed. Save feed.
8. 饲料。按比例进行精料、粗料阶段的合理搭配。猪前重50公斤，60公斤，以高能量、高蛋白浓缩。含有必要的饲料添加剂;在50kg ~ 60kg的柱上，适当降低精矿中的能量和粗蛋白水平，减少精矿的投料量，增加绿色粗料的投料量。这样，可以节约精华，降低成本。
8. feed. Reasonable mix of fine and coarse materials in proportion. The pig weighs 50kg and 60kg in front, which is concentrated with high energy and protein. It contains necessary feed additives; on a 50kg ~ 60kg column, the energy and crude protein level in the concentrate are properly reduced, the feeding amount of the concentrate is reduced, and the feeding amount of the green coarse material is increased. In this way, we can save the essence and reduce the cost.
Use feed additives. In the diet of pigs, adding minerals, trace elements and multi vitamins properly can promote growth and save feed. According to the experiment, 0.2% feed additive was added to the basic feed of pigs (no additive was added to the full price feed). The average weight gain of the experimental group was 12.38kg more than that of the control group in 92 days. For every 1kg increase, 0.91kg of materials will be reduced.
10. In due course. Pigs weigh from 20 kg to 90 kg. The daily weight gain shows linear growth; the daily weight gain of more than 100 kg gradually decreases, so it's better to raise pigs to about 90 kg.
