With the continuous development of the rural economy and the increasingly rich source of feed, pig-raising has gradually evolved from the traditional method of “mainly using green coarse material and appropriately matching fine material” to science rearing. Therefore, rural pigs should pay attention to the following issues in feeding technology.

Feeding and Feeding Many pig farmers have a habit of feeding cooked food, and think that cooked pigs can eat more. In fact, this is a misunderstanding. According to the experiment, the type of feed is different, and the difference between raw and cooked feeds is that the green and coarse feed type feeds are better fed than the raw feeds, while in the concentrate type feeds, the feed of the seed beans is better than raw feed. However, most of the concentrate type diets are still fed better than cooked ones, and generally the cooked concentrates will lose 5% to 10% of nutrients. Feeding raw pigs, the average daily weight gain is 10% higher than that of cooked feed, and each additional 1kg of gross weight can save 0.2~0.3kg of fine feed. Of course, some toxic or easily contaminated feeds, such as rapeseed cakes, cottonseed cakes, glutinous water, etc., should be cooked and then fed after being detoxified or disinfected.

Thick-feeding and thin-feeding thin-feeding, due to the large amount of water, easily lead to reduced secretion of digestive juices, accelerated gastric emptying, shortened feed retention time in the stomach, and affect nutrient absorption. Thick-feeding, in particular, raw dry feed and raw wet feed, can enhance the chewing performance of pigs, promote the secretion of digestive juices, prolong the stay of feed in the stomach and improve the digestibility of nutrients. Therefore, it is advisable to use thick-feeding, dry-meal water-mixing, or dry-meal-mixed green feed slurry water to dry and wet.

Small meals and multiple meals The suckling piglet has a small stomach volume and weak digestion. From the 7th day of age, it is mainly lure-feeding. It can limit the number of meals and allow it to feed freely. From the 20th day of age, weaning and feeding small meals are daily. Can feed 6 to 8 meals; freshly weaned pigs are in a growing stage of feed digestion, feeding 4 to 6 meals a day; sows with sows and late sows, need more nutrients, daily Feed 4 meals; shelf pigs, big pigs, empty sows, boars feed 3 meals a day. In summer, the weather is hot, the nights are long and the pigs are active for a long time. You can feed 1 to 2 tons of green feed as appropriate. Cold in winter, long nights, can be fed early in the morning and late in the evening, and the interval between meals should be properly opened. And in the evening one meal should be fed thicker and more.

Timing and quantitative feeding of pigs must develop good feeding habits, have a fixed time. Usually set at 6 o'clock in the morning, 12 o'clock noon, 6 o'clock in the evening is appropriate, different seasons can be adjusted.

While doing a good job of regularly feeding pigs, we must also do feed ration. When you understand the approximate feed intake of your pig, you should determine a general feed amount. Generally, it is best to feed the pig for 1 hour without feeding the trough and without any food left in the trough.
