In 2017, it seems that it is really not suitable for breeding. There is a prohibition order for raising pigs. Bird flu is occurring in chickens. The hot summer has already arrived, and farmers are also suffering from summer anxiety. Recently, the price of pigs has fallen all the way. It has been very bad since it fell from 8 yuan to 7 yuan. Now it has fallen to 6 yuan. Although the price of live pigs is growing well, the market is still unclear, so what is the reason for the majority of pig farmers? The strongest "pig cycle" market in the year harvested the pigs who were full of pigs, and one accidentally stepped into the cycle inertia of the rapid decline of the pig price. In the future, can pigs still make money? What should the pig farmers do in the second half of 2017? HuiNong.com has compiled relevant information for the farmers to refer to.
Why are your sows not productive?
One of the difficulties in raising pigs is that the number of follow-up piglets cannot keep up, which has become a key bottleneck for the development of pig farmers. So how can the sows quickly estrus and produce high yields? In fact, an important factor affecting the reproductive capacity of sows is the combination of feed nutrition. By regulating feed nutrition, it can effectively promote the breeding ability of sows, which has become a key technology that pig farmers must consider and learn. So how do pig raisers regulate the feeding process of sows? In fact, just do the following points.
Nutritional regulation of sows during 30-85 kg period
When the weight of the sow reaches 30 kg, the feed energy is 13 MJ, the crude protein is 16%, the lysine is 0.8%, the calcium is 0.75%, and the scale is 0.65% for each kilogram of feed. At this time, the sow is free to eat and does not control the food intake. This will promote the growth of sows as soon as possible. Starting at 45 kg, the calcium and scale in the feed need to be increased by 0.1 percentage point. After the sows are 5 months old and need to limit their food intake after gaining more than 85 kg, they are also fed according to the above criteria. The total daily food can be controlled at 2.3-2.8 kg according to the physical condition.
Nutritional regulation from 110 kg to childbirth
It is appropriate to carry out the first mating when the sow reaches 8 months old and weighs 110 kg. The first estrus should not be bred, and the ovarian function of the sow is not fully developed, and all the estrus is better. Before the breeding, it is necessary to supplement the feed aphrodisiac two weeks in advance, and it is necessary to increase the dosage by 40% to 50% to achieve a compound feed of about 4 kg per day. This can increase the amount of ovulation in the sow, and you can add two more pigs per litter. Immediately after the end of breeding, reduce the level of feed to the level before the aphrodisiac, 2.2 kilograms a day, containing 12.1 megajoules of digestible energy per kilogram, 13 percent crude protein, 0.6 percent succinic acid, and calcium percent. At 0.75, the scale is 0.66 percent. From the 84th day of Huai Tsai, the daily nutritious food can be increased to 13 MJ per kilogram of digestible energy, 14% crude protein, 0.75 percent succinic acid, 0.80 calcium, squama 0.65. The daily feeding volume is controlled at 3.25-3.5 kg, which can be reduced to 1.8 kg two or three days before delivery, which can prevent the sows from being overproduced due to excessive piglets.
Nursing regulation of lactation in postpartum sows
For 5 to 7 days of sows, the amount of feed should be gradually increased to the maximum. Based on 1.5 kg of daily feed, 0.5 kg of feed should be added for each additional pig. For example, 9 piglets need to feed 6 kg. If the sow has a poor appetite, it is necessary to add two to four percent of the fat in the feed and provide the protein content to ensure that the sow's milk is sufficient. During this period, each kilogram of feed should contain 13-14 MJ of digestion energy, 15% crude protein, 0.7-0.75 percentage of succinic acid, 0.84% ​​calcium and 0.75 percentage of scale.
Through the above feeding methods, the sow's litter size can be maximized, and the yield of piglets can be significantly improved. It is the best combination of scientific observation and record, which can ensure the economic benefit of pig farmers. Therefore, in the cyclical economic competition, the most competitive advantage is maintained, thereby avoiding the ability to resist risks when various economic environments deteriorate. Feeding sows according to this rule can ensure the balanced nutrition of the sows, and the health of the piglets greatly reduces the probability of occurrence of the disease, thereby effectively increasing the income of the breeders.
