Black pigs on the market are much more expensive than white pigs, and everyone knows. In addition to the slight difference in taste, it is not enough to make the price of black pigs much more expensive than the price of white pigs. So what are the differences between black and white pigs? The following is a small analysis of the difference between black pigs and white pigs and the reasons for the high price of black pigs. First, the difference between black pig and white pig growth cycle The growth period of black pigs is about one year, and its physiology can reach full maturity, while the growth cycle of white pigs is generally about 4-5 months, and it is not fully matured physiologically. Second, the difference between black pig and white pig breeding costs Black soil pig: The free-range sports field is large in area, scattered in layout, high in labor, transportation, transportation, management, etc.; less pollution in land, mountain forest, water body, atmosphere, high cost of ecological environment control; long growth cycle, large amount of movement, high consumption of materials, high cost Production, processing equipment, packaging, anti-counterfeiting and other standards are high and the investment is large. White pig: Large-scale production, centralized layout, low labor, transportation, transportation and management costs; serious pollution of land, water, air, etc., low environmental control cost; short growth cycle, small amount of exercise, poor feed quality, low price; low consumption, cost Low; production, processing equipment, packaging, etc. have low standards and low investment. Third, the difference between black pig and white pig feed The feed for organic black pigs is mainly cereals, vegetables and wild vegetables. The nutrition is balanced, the season of birth is different, and the feed is different. The ordinary feed for white pig feeding is single, the nutrients absorbed are less, and the additives in the common feed are many, which seriously affects the health of the white pig. Fourth, the difference between black pork and white pork cholesterol content Black pork contains 52.15 mg of cholesterol per 100 grams of meat, which can reduce the incidence of high blood pressure, high blood fat, coronary heart disease, etc., while white pork contains 106.90 mg of cholesterol per 100 grams of meat, which is twice that of black pork. Human health is not good. The above points are the difference between black pigs and white pigs. Because the feeding and cost of black pigs at the beginning is higher than that of white pigs, it is natural that black pigs are also more expensive than white pigs. The following small series will introduce the technical points of black pig breeding as follows. Black pig feeding technical points: Black pig feeding, feed should be diverse and reasonable, to ensure comprehensive nutrition. Feeding the pig's green fodder, roughage, and concentrate, only a reasonable mix can guarantee the pig's need for various nutrients. Pay attention to the relationship between dietary volume and pig intake. The feed dry matter content can be measured by the size of the feed volume. According to the daily dry feed of 2.5-4.5 kg of feed per 100 kg of pigs, the dry matter ratio of the three feeds of green feed, roughage and concentrate should be 5:3:2. For green fodder, black pig breeding should choose fresh, multi-leaf, high-protein, and palatable grass. The grass species suitable for raising pigs are hn-mc excellent rye, hn-mc excellent granules, hn-mc excellent lycium, etc. These pastures have higher nutritional value than wild grasses. The pasture should be aired before feeding. Generally, pigs are fed 2 to 3 times a day. Male (female) pigs and fattening pigs can be used twice a day, and piglets and growing pigs can be fed three times a day. Feeding schedules should be avoided when the noon weather is hottest and when people are most active. The black pigs are managed in divided circles. After 60 days of age, they should be kept in separate circles, with 2 to 3 pigs per lap, so as not to be able to chase after running outdoors. The sow empty stage and the first 80 days of pregnancy can be used for green feed, high-quality roughage and dregs, and only about 1 kg of concentrate per day. One to three kilograms of concentrate are fed daily 1 month before delivery. In this way, the normal development of the fetus is guaranteed, and the sow can save 60-90 kg of concentrate for every pregnancy. Small boars 30 days old and gilts 40 days old castrated, respectively, are about 15% heavier than the 60-day-old castration, and the wounds heal faster. Weaning 60-day-old piglets early to 40 to 45 days, this can promote early estrus, early breeding, shortening the empty period, and relatively saving feed. Black pig breeding should be disinfected on time, and the cage should be cleaned. The feces and dirt should be cleaned and removed every day. The cage should be disinfected once a day with disinfectant. To do a good job of immunization, according to the pig's health and epidemic prevention procedures, triple vaccine injection, and timely deworming, gastric lavage and stomach, to be carried out the second time after 60 days. At the same time, attention should be paid to the management of the humidity and temperature of the pig. The suitable temperature of the pig is 15 to 25 ° C, and the relative humidity is 55% to 60%. If the temperature and humidity are too high, it is easy to cause heatstroke and metabolic disorders, so when the summer temperature exceeds 28 At °C, it is necessary to use water to cool the cage at noon, scaffolding the sunshade; if the temperature and humidity are too low, the pig body will have more heat and consume more feed, which will increase the cost of feeding. Therefore, in winter, it is necessary to keep warm and keep warm, and the cage needs to be padded. ~15cm thick hay, while mixing with warm water. The difference between black and white pigs and the black pig farming technique is introduced here. Black pigs are more difficult to farm than white pigs, and management is more demanding. Therefore, the price of black pork is also relatively higher than that of white pigs. Organic black pigs are more nutritious than white pigs. Organic black pigs have much lower cholesterol than ordinary white pigs. They contain much more mineral elements, proteins and unsaturated amino acids than ordinary white pigs.
Health foods contain a certain amount of functional health ingredients, which can regulate the functions of the human body, have specific effects, and are suitable for specific groups of people. General food does not have specific functions, and there is no specific range of people to eat. Health food cannot be directly used to treat diseases. It is a human body mechanism regulator and nutritional supplement.
