[0044] Example 1
[0045] In this example, the growth performance of the large white pig is measured in the pig field, while the size of the pigs is measured, and the total number of births of childbirth is collected, and the number of people who produce the number and other reproduction data. After collecting data, correct the age, back to thick, body length, and body height, calculate 100kg body weight, up to 100kg body weight, total number of bodies, up to 100kg body weight and up to 100kg body weight 5 Breeding value of traits. According to the breeding objectives of the breeding field and the focus of breeding, the character should be weighted according to certain weights, and finally obtain a comprehensive selection index. Finally, the seed pig selection and optional breeding work is performed according to the comprehensive selection index. The specific method is as follows:
[0046] (1) Determination of large white pigs to the measurement standards, while determining the si...

[0082] Experimental Example 1
[0083] The effects of pork were subjected to the selection and option of the signs of the stroke to the integrated selection index to evaluate the effects of the method. This experimental case is conducted based on a large white pig in a core breeding ground in Fujian.
[0084] The following table shows the ten-head individuals that are excellent in the target groups, which are excellent in selection of pigmentation performance (capabilities), wherein index 1 (index1) is a comprehensive selection index that does not include a size, index2 (index2) is a body foot. Comprehensive selection index of traits. Retention and options can be obtained in accordance with the comprehensive selection index including the size of the size.
[0085] It can be seen that a comprehensive selection index of the growing performance is more accurate to obtain a well-measured individual, which is more accurate, and more accurate, a comprehensive selection index that consid...
