Feeding restriction methods and matters needing attention of pigs
1. Feed restriction methods and matters needing attention should be considered to achieve the best feed-to-meat ratio. Pigs before 50 kg should not be used, and after 50 kg, different feed restrictions can be made according to the breed.
The points for attention in feed restriction are as follows: pigs in the same column must have similar body weight, otherwise it will easily lead to the law of the jungle; sufficient feed trough and pigsty area are required so that pigs can eat feed at the same time (the average feed trough for fattening pigs weighing 60 to 100 kilograms should be 30 cm long); excessive feed restriction will prolong the age of sale, so the building capacity of the pig house should be corresponding; the feed formula should use high-quality raw materials. When implementing feed restrictions, the effect is better if male and female are raised separately; for those who need feed restrictions, boars are better than sows, poor breeds are better than breeds, and the cold season is better than the hot season; if you want to delay the sale, the amount of feed can be reduced by about 5%, but it should be noted that if the feed restriction is too serious, the weight gain and meat exchange rate will become worse, and the lean meat rate will not be increased.
Second, male and female separate feeding if your pig farm is large enough and convenient to manage, you can carry out male and female separate feeding. Separate feeding of male and female can make your pigs neatly consistent. More importantly, the nutritional needs of castrated boars are different from those of sows. With different nutritional needs, castrated boars can be fed more cheaply to achieve the purpose of reducing costs.
3. Breeder pigs should be fed as usual, and poor feed or reduced feed intake should not be used. People who have this idea might as well not @ # @ 227 pigs @. The breeding pig is the locomotive of a pig farm, and the feed quality and feeding quantity directly affect the reproductive performance, which can not be missed at all, otherwise, once the reproductive performance decreases, the cost shared by each pig will eventually increase, and the loss will definitely outweigh the gain.

Prevention of common diseases in pigs in winter
Before the arrival of winter, do a good job in the immunization of breeding pigs, such as foot-and-mouth disease, epidemic diarrhea, transmissible gastroenteritis, classical swine fever, pseudorabies dogs, blue ear disease, and do a good job of deworming. Sow immunization: the injection of transmissible gastroenteritis, epidemic diarrhea vaccine and pseudorabies vaccine should be done according to the plan, so that the sow is at a high level of immunity. Immunization of pigs: the immunity of blue-ear disease is controversial, so it is recommended to use attenuated blue-ear virus vaccine at 15 days old. Drug prevention

Processing technology of chicken pine
Raw material formula 50 kg soy sauce 8.5 kg refined salt 1.5 kg white granulated sugar 3 kg ginger 250 g 50 degree sorghum wine 500 g monosodium glutamate 150 g. Production method 1. Raw material refurbishment: light chicken with plump muscle is used as raw material, washed and beheaded and clawed for use. 2. Boil roast: clean the chicken with chopped head and melon and put it into the pot, add ginger and proper amount of water, cook for about 3 hours, and constantly turn it up and down to heat the chicken evenly. Then take it out for bone removal, peeling,
