1. Appearance characteristics of Duroc pigs
The coat of Duroc pig is reddish brown and golden yellow with different shades, and there may be small black spots on the skin. Ears of medium size, leaning forward, slightly concave face, slender body, wide and deep chest, plump muscles, stout limbs, black hooves, arched back and straight belly line.
2. Growth and fattening performance
The growth rate is fast, and the age of 180 days can reach 100 kg. After breeding, the weight of Duroc pig 159 days old can reach 100 kg. It consumes 2.4-2.6 kg of compound feed per weight gain 1 kg, which is a pig breed with high feed utilization rate at present, and the suitable slaughter weight is 90- 100 kg. The slaughter rate was 75%, and the carcass lean meat rate was 64%.
3. Reproductive capacity
Duroc pigs have a late sexual maturity, and generally start estrus at the age of 6-7 months, and can only be bred after 8 months. The estrus cycle is 265,438+0 days, the duration of estrus is usually 3 days, the pregnancy is 65,438+065,438+05 days, and the litter size of multiparous sows is 9-65,438+00.
4. Main advantages and disadvantages
Duroc pig is strong and adaptable. There are no adverse reactions in the vast agricultural areas of our country. The growth rate is very fast, with an average daily gain of 700-800g during the fattening period, especially in the late fattening period, with the daily gain exceeding 1 1,000 g. It is the highest among American pigs and performs well in China. In addition, Duroc pigs are more tolerant of extensive feeding than Landrace pigs. Its disadvantage is the small number of children. In the case of slightly poor feed conditions, the lean meat rate of carcass decreased rapidly.
5. Hybrid utilization
China was just introduced in the early 1980s, and it performed very well. Domestic universities and scientific research units are disappointed to use it for hybridization experiments. The effect of binary hybridization or ternary hybridization between Duroc pig and local varieties and cultivated varieties is better than other pigs. The binary hybrid pig with it as the terminal male parent gains more than 700 grams a day. In the late fattening period, the daily gain was nearly1000g, and the carcass lean meat rate could reach 58%. The lean meat rate can reach about 60% by controlling feeding restriction and fat deposition rate in the later stage. From a large number of experiments, Duroc is better than Changbai, Dabai and Hampson as the terminal father.
2. What is the price of Duroc pig? How much is a Duroc boar?
Duroc boars generally cost 4000 to 5500. According to the quotation, the price of Duroc boar is also 8000 yuan, and there is also 10000 yuan, which varies according to the quality.

3. What is the price of Duroc piglets? How much is a Duroc piglet? Duroc piglet price:

4. How much is a Duroc boar? The price of Duroc boars in the market is different, and the prices in different provinces will be different. For example, it costs about 4,500 yuan in Shanxi Province, about 3,800 yuan to 65,438+ten thousand yuan in Shandong Province and about 8,000 yuan in Henan Province, so the overall price is about 4,000 yuan to 65,438+ten thousand yuan. You can compare the local prices and then choose the place to buy.
Usually, when you buy Duroc boars, the price will change according to your needs. For example, whether you choose a reserve boar or a boar, the price between them is different. It will be relatively cheaper to choose reserve boars, and boars can be directly used as breeding pigs, so the price will be relatively expensive.
When buying Duroc boars, we should pay special attention to the selection of breeding boars. First of all, you should look at its size, whether it meets the basic characteristics of all varieties, and then you should look at its reproductive function. If sexual desire is low and semen quality is poor, don't choose.
