The advantages and disadvantages of Duroc! Request details

The advantages of Duroc pigs are: extremely fast growth and development, average daily weight gain of 700 to 800 grams during the fattening period, especially in the late fattening period, daily weight gain of more than 1,000 grams, and they are more resistant to extensive feeding. The lean meat rate is high, the feed return is good (the feed-to-meat ratio is low), the lean meat color is good, the limbs are strong, and boar breeding is relatively active.

The disadvantages of Duroc pigs are: the number of offspring is low; the carcass lean meat rate drops quickly when the feed conditions are slightly poor; relatively speaking, the maternal nature of pigs is relatively weak, so it is often used in actual work. Use Duroc as the terminal parent.

The production performance of Duroc pigs:

Duroc pigs have fewer litters, with an average of only 9 to 10 piglets in large groups, but they grow quickly, have high feed conversion rates and are resistant to stress. Strong sex. Daily weight gain from 70 days old to 100kg: 750g. Feed reward from 70 days old to 100kg: 2.8:1.

Days from birth to 100kg: 170 days. The daily weight gain of fattening pigs at the 25-90 kg stage is 700-800 grams, the feed utilization rate is 2.8-3.2, and the age of reaching 90 kg weight is less than 170 days; when slaughtering 90 kg, the slaughter rate is more than 72%, and the carcass lean meat rate is 61 ~64%; the meat quality is excellent, and the intramuscular fat content is as high as more than 4%.
