Which wrong experiences of farm pig raising should be corrected?

Farmers raise pigs

Farm pig raising often mentions some experience, there is no denying that there are many traditional pig raising experiences in rural areas that can be used for reference, but there are also many experiences that are unreliable.

1. "cooked feed easy to grow oil". The traditional method of raising pigs is to cook feed and feed them. It is believed that pigs can easily grow oil when they eat cooked food. In fact, cooked feeding pigs take time, labor, feed consumption, slow growth, feed utilization rate is not high; feed in the process of cooking 20% of the loss of nutrients, green feed loss is even greater, cooked feed fat is slow, raw feeding can greatly reduce energy consumption and labor costs, scientific and reasonable feeding, can shorten the feeding period by 3-5 months.

two。 The Winter Solstice kills pigs to make bacon. It is generally believed in rural areas that the Winter Solstice's bacon tastes the best, so fat pigs that can be fenced before the Winter Solstice should also be dragged to the Winter Solstice for slaughter. The optimum temperature for the growth and development of pigs is 18 ℃ ~ 23 ℃. Pigs below 18 ℃ grow slowly. In winter, the temperature decreases. Considering the feed cost, fattening pigs should be slaughtered as early as possible.

3. Feed "the thinner the better". The dilute feed has more moisture, which reduces the temperature of pig intestines and stomach, increases the consumption of pig heat energy, and excretes quickly, which is not conducive to digestion and absorption, and reduces the conversion rate of feed.

4. Feed the pig "the fuller the better". Pigs eat too much and affect their appetite for the next meal, wasting feed. Pig's appetite rule: eat more in the evening, the second in the morning, and the least at noon. It is best to feed 90% of each meal.

5. Pigs "the bigger they are, the longer they are willing to grow." The growth of pigs has its own law, and the growth of pigs with more than 100 kilograms becomes slow. Therefore, pigs should be fed to a certain extent in time according to different breeds, and it is better to have a body weight of 90kg and 100kg. The fat pig has the advantages of excessive weight, high feed consumption, high feeding cost and low benefit.
