Description
Technical Field
The invention relates to a pig breeding technology in the field of ecological breeding, in particular to a method for free-range breeding of domestic pigs in mountainous regions.
Background
Pork is the main animal protein and fat food of people in China, the pig raising industry is one of the important industries in the animal husbandry in China, and the positive development of the pig raising industry has positive effects on guaranteeing the safe supply of meat food. With the continuous development of the breeding industry, no matter the breeding mode, the regional layout, the production mode and the production capacity of the pig breeding industry in China are obviously changed, commercial pigs are generally bred in captivity in the traditional pig breeding method, the live pigs are fixedly bred in a narrow space and fed with feed which has high energy, high additive content and even hormone, the growth cycle is short, the growth speed is high, but the meat quality is poor, toxic ingredients are easy to remain in the pigs in the breeding mode, the health of people is seriously influenced after eating the feed, and the food poisoning caused by the meat and meat products is the most in the food safety problem events in China.
With the idle land in vast rural areas in China, farmers who contract idle land to free-range livestock begin to appear in many places, the free-range livestock breeding mode conforms to natural laws and ecological principles, coordinates the balance of planting industry and breeding industry, effectively utilizes resources in free-range areas, reduces the use of pesticides, fertilizers, feed additives and hormones, and is a sustainable development agricultural mode. However, most of the existing rural free-range breeding is mainly poultry such as chickens and ducks which are mature in technology, easy to survive and short in growth period, most of the poultry such as pigs, cattle and sheep are bred in a small scale and are not concentrated, and in addition, as most of farmers do not have professional training, the breeding method is unscientific, and the problems of low yield, slow growth, high morbidity, high cost and low profit rate occur. However, with the improvement of the awareness of people on ecological food and the improvement of food safety, the pollution-free ecological pork gradually occupies the market leading position, so that the technology for free-ranging pigs by utilizing an ecological structure is required to be improved, and on the premise of strictly following the breeding standard, better economic benefit and social benefit are obtained by utilizing a breeding mode which is suitable for local conditions according to the environmental characteristics of different regions.

The method comprises the steps of disinfecting a buffer area and a pigsty twice at intervals of three days before entering a pigsty, placing for two weeks after disinfection, keeping ventilation and drying in the period, paving an organic fermentation filler with the thickness of 20 ~ 30mm and the humidity of 50 ~ 60% on the surface of the fermentation bed before introducing the pigs, wherein the organic fermentation filler comprises rice hulls, loess, sawdust, sugar residues, corn flour, yeast powder, enterococcus faecalis powder, bacillus subtilis powder and saccharomycetes powder, and is filled in the fermentation bed after being prepared according to bacterial material preparation instructions, and the organic fermentation filler can convert part of pig manure and pig urine into fertilizers through fermentation of soil microorganisms, and keeps the temperature of the pigsty in the conversion process.
When the pigs are introduced, selecting offspring pigs bred by the own breeding pigs in a local pig farm as fattening pigs for feeding; the piglet is required to be healthy and pure, the hoof is thin and hard, the bouncing force is good, the vitality is strong, the size of each head is consistent, the piglet is placed into the piggery for feeding after being strictly quarantined and disinfected, meanwhile, a self-breeding mode is adhered to, the introduced piglet is not more than 6 weeks old and is weaned, and the amount of the introduced piglet in half a year cannot exceed 10% of the number of the boars in the field.
In the daily maintenance process, 8 ~ 9 o' clock in the morning of every day opens the door between pig house and the buffer area, lets the pig freely move in the region only, in time supplyes the fodder and the drinking water in drinking water subassembly and the fodder subassembly of throwing something and feeding to it only can to catch the pig back to the pig house after the sun falls the mountain.
Cleaning pig manure scattered in a free-ranging area every other day, turning over the fermentation filler in the fermentation bed once every other week, supplementing zymogen liquid, and regularly sterilizing and cleaning, wherein the pig manure can be driven into a pig house, and the pig can be driven into a buffer area or a free-ranging area after the pig manure is sterilized, turned over and replaced by the fermentation filler. Meanwhile, daily heatstroke prevention and cooling operation and epidemic prevention are well performed, the pigsty is kept ventilated, clean and sanitary, padding is dry and fresh, and the free activity of the padding is kept.
In the embodiment, a planting base is also built at the periphery of the free-ranging area, the planting base provides organic feed for cultivation and can output organic vegetables, and meanwhile, pig manure and the like fermented by a fermentation bed are provided for crop production as organic fertilizers so as to form ecological cycle.
In the embodiment, the raised pigs only use organic feed as a food source, the organic feed comprises broussonetia papyrifera leaves, sweet potatoes, sweet potato leaves, organic corns, organic vegetables, beans and bean pulp, the daily average feed supply amount in the house is ~ 4% of the total weight of the pigs, the feed supply mode of the free-ranging area is supplemented in real time, and freshness is ensured, and when the trace elements and the vitamins are supplemented, the added trace elements and the vitamins are from germinated grains, cod liver oil, distiller's yeast or other natural substances.
In the embodiment, during disinfection treatment, daily disinfection is carried out by spraying the disinfectant once after the pigs only migrate out of the treatment area; when the disinfection treatment is carried out regularly, the treatment area needs to be thoroughly cleaned by clear water, and then the disinfectant is sprayed for more than three times to complete the thorough disinfection.
After the pigs are bred for three years, the live pigs are slaughtered; slaughtering and processing slaughtered live pigs subjected to strict inspection and quarantine; the processed pork product is antibiotic-free and safe pork food meeting the national standard.
