What is the risk of breeding black pigs with a good ecological environment?

With the life getting better and better, people have higher and higher requirements for eating. We all know that wild boar meat is better than domestic pork! Not only that, black pork is also better than domestic white-haired pork. The point is that today's black pigs are raised ecologically. So the question is, can black pigs be raised at home? Is there any risk in ecological breeding of black pigs? Which breed do you choose to raise black pigs? Let me study it together.

It is good to choose which breed to raise black pigs

I. Min Pig

1. Origin: Heilongjiang, Jilin, Liaoning, Hebei and other provinces.

2. Main characteristics: medium-sized head, straight face, drooping ears, flat body, narrow back and waist, inclined buttocks, stout limbs, black body coat, dense fluff in winter. Strong cold resistance. There was no tremor at-28 ℃ and normal litter feeding at-15 ℃. The average weight of adult boars is 195 kg and that of sows is 151 kg. The prematurity of each part of the carcass appears successively according to the order of bone-muscle-skin-fat. The sows matured early, the sows had first estrus at the age of 4 months, the diameter of the follicles was 900 to 1000 microns, and the ovulation at the age of 9 months was about 15. There were 11 first births, 11.9 third births and 13.5 more than four births. During the fattening period, the daily weight gain was 458 grams, and the slaughtering rate was 72.5%. After the body weight reached 90 kilograms, the fat increased and the lean meat percentage decreased.

2. Bamei pig

1. Origin: the central producing areas are mainly distributed in Gansu, Ningxia, Shaanxi, Qinghai, Xinjiang, Inner Mongolia and other provinces and regions.

2. Main characteristics: long and narrow head, drooping ears, vertical wrinkles of the word "eight" on the forehead, hence the name "eight eyebrows", divided into three types: big eight eyebrows, two eight eyebrows and small pigs, and two eight eyebrows are in the middle between big eight eyebrows and small pigs. The coat is black. Slow growth and development. The average weight of adult boars is 104 kg, and that of sows is 80 kg; that of Erbamei boars is about 89 kg, that of sows is 61 kg; that of young boars is 81 kg, and that of sows is 56 kg. Boars weighed 40 kg at 10 months and sows weighed 45 kg at 8 months. The number of babies born was 6.4 for the first time and 12 for more than three births. During the fattening period, the daily gain is 458 grams, the lean meat rate is 43.2%, the muscle is marble striped, the meat is tender and tastes fragrant.

What is the risk of raising ecological black pigs?

1. Swine disease is prevalent on a large scale.

2. Large-scale pig farming competes with individual farmers for a price war.

3. The state's macro-control of agriculture to promote the rise of food prices will directly lead to a rise in feed prices, but there is too much room for rising pig prices to lead to a decline in profits.

4. There is no favorable guarantee for the purchase of young pigs from other places.

Conditions for selecting black pig breeds

1. High lean meat rate: consumers prefer and accept it.

2. High slaughtering rate: higher meat yield makes more money when the price is the same.

3. Strong disease resistance: less or no illness, less medication or no medication, and pork quality reaches a higher level. The Sichuan-Tibetan black pig raised in our forest native pig base is a breed that meets the appeal conditions at the same time. In addition, Sichuan-Tibetan black pork has a higher fat content in muscle and tastes better than ordinary black pigs.

What are the temperature requirements for raising young black pigs?

The suitable temperature for suckling piglets is 31.8 ℃-28.3 ℃ at 7 days old and 27.7 ℃-23.5 ℃ at 35 days old. The temperature in the house is controlled at 18.3 ℃-22.1 ℃, and the relative humidity is 49.7% Mel 70.4%, keeping the air fresh. Piglets should be equipped with an incubator or greenhouse, and hang a 250-watt infrared light bulb at the bottom of the incubator or 30,000cm away from the greenhouse. At the same time, do a good job in piglet care, and install a guard fence in the delivery column.

Whether it is raising black pigs or white pigs, young pigs should be selected according to local conditions. Local materials, convenient, low-cost breeding. Do not indiscriminately add growth feed to give consumers a safe and assured consumption environment. If you need breeding, hurry up and get moving!
