Problems solved by technology
The main function of the hanging hoof is to assist the main hoof to bear the weight of the pig and maintain its body balance. When the hanging hoof of the sow is too long (greater than 7cm), it is very easy to cause mechanical damage, which will cause it to be unable to stand and eat, and subsequently cause pregnant mothers to lose weight. Pig abortion, lactating sow malnutrition, etc. (see figure 2 ), thus affecting all aspects of sows, and in serious cases, sows will be eliminated directly, which will bring huge economic losses to the breeding enterprises

Embodiment Construction
[0026] The present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0027] The above-mentioned purpose of the invention of the present invention is specifically achieved like this:
[0028] 1. Experimental pigs
[0029] The experimental pig group used in the present invention is 475 purebred Large White sows from the breeding pig branch of Guangdong Wen's Food Group Co., Ltd., which is the core group of the breeding pig branch, and the group pedigree records are detailed. The same feeding method is used for feeding and management by professionals. The pigs were raised according to the unified pig nutrition standard, and they had free access to food and water. The experimental pigs were healthy, growing well, and had no clinical symptoms.
[0030] 2. Sample collection and phenotype recording
[0031] The above pig ear tissue samples w...

The invention provides an SNP marker related to hypertrophy properties of a pig nail. The SNP marker has a site which is the 133470903rd nucleotide site on a 13th chromosome of an international pig reference genome 11.1 edition, and the site has an alkali group of T or G. Dominant alleles of the SNP are preferred, hypertrophy of a large white pig nail is reduced, a genetic progress is accelerated,and the economic benefits of pig breeding are effectively increased.
Description
technical field [0001] The invention relates to a SNP marker related to the overgrowth trait of hoof hanging in pigs and its application. Background technique [0002] Pigs are typical artiodactyla mammals. The first toe is completely degenerated; the third and fourth toes are particularly developed and equal in length, which is called the main hoof; hanging hoof (see figure 1 ). The main function of the hanging hoof is to assist the main hoof to bear the weight of the pig and maintain its body balance. When the hanging hoof of the sow is too long (greater than 7cm), it is very easy to cause mechanical damage, which will cause it to be unable to stand and eat, and subsequently cause pregnant mothers to lose weight. Pig abortion, lactating sow malnutrition, etc. (see figure 2 ), thereby affecting all aspects of the sow, and in serious cases, the sow will be eliminated directly, which will bring huge economic losses to the breeding enterprise. [0003] Since the final len...
