The invention belongs to the fields of molecular biology and molecular breeding. Specifically, the present invention provides a SNP molecular marker on the BMP2 gene of Small-tailed Han sheep related to multiple fecundity traits, a detection method of the molecular marker and the application of the method in improving the reproductive performance of sheep and breeding multiple fecundity varieties. The molecular marker is the polymorphic site at position 76 of exon 2 of BMP2 gene, denoted as C76T. Statistical analysis showed that the molecular marker C76T was significantly correlated with multiple birth traits, and the allele T had a significant additive effect. Therefore, in the process of breeding and breeding sheep, the SNP molecular marker can be used to assist in the selection of CT-type or TT-type individuals with high fecundity, thereby accelerating the breeding process of sheep reproductive performance.

The invention discloses a rapid and visual detection method for sheep multifetal main gene FecB. The steps of the detection method are: (1) collecting individual sheep muscle tissue samples and extracting its genome DNA; (2) searching for the DNA of the FecB gene from a GeneBank database Sequence, design ARMS-specific primers for the SNP site of FecB, that is, the last base at the 3' end of the downstream primer is complementary to the SNP site, and the length of the primer should be about 20bp; (3) Using the above primers, the nucleic acid dye SYBR Green Ⅰ was added to the PCR reaction system, and it was judged whether the sheep carried the main multiple-fetal gene FecB by directly observing the color change of the reaction system, that is, the sample carrying FecB was bright green, otherwise it was orange-yellow. The detection method of the invention has high sensitivity and accuracy, and can quickly, visualize, and low-cost detect the main effect gene of multiple births in sheep.

The invention provides a method for increasing the litter size of multiparous animals through oral administration of melatonin. The method increases the litter size of the multiparous animals by adding melatonin in fodder or drinking water of the multiparous animals in the gestation period so as to achieve the purpose of improving the fecundity of the animals. The method can increase the average litter size of mammals like mice by 0.48-1.38, and provides a good reference for research on improving the fecundity of mammals.

The invention provides feed for promoting estrus and pregnancy of female forest musk deer. The feed is prepared from seeds of Chinese dodder, rhizoma cyperi, epimedium, prepared rehmannia root, herba lycopi, leonurus, patrinia and corn starch. If female forest musk deer eats the feed in the mating preparation period, the pregnant rate and the rate for having multiple births can be increased. The invention also provides a method for breeding female forest musk deer with the feed. According to the method, a proper amount of feed is fed to female musk deer in the mating preparation period, after the feed is fed for 20 to 40 days, the illumination time and temperature of a female musk deer living environment are controlled, the temperature and the illumination are regularly changed, the temperature is gradually reduced, the illumination time is gradually shortened, and the pregnancy rate and the rate to have multiple births of female musk deer can be remarkably increased.

The invention relates to a multifunctional device convenient for transporting pregnant women and belongs to the technical field of medical apparatuses. The multifunctional device aims at the problems that the bloated lower limbs of multiple-birth pregnant women are not alleviated by the existing means of transport, and the attendant oxygen uptake is also inconvenient. The technical scheme is as follows: one end of a fine-tuning inflatable pipe (18) with an air inlet and escape switch (19) is fixedly connected and communicated with an extrusion inflatable balloon (17), and the other end of the fine-tuning inflatable pipe (18) is fixedly connected and communicated with an inflatable pipe joint (4); a miniature insertion type oxygen cylinder sleeve (20) is arranged on a pedal plate (2); two leg and foot placing grooves (16) are arranged on an inflatable abdomen supporting stand column (1); two dovetailed slideways (15) are respectively fixed on a bedplate (6); and dovetailed sliding plates (12) on which positioning screws (14) are screwed are embedded on the dovetailed slideways (15). The multifunctional device has the advantage that the multifunctional device has multiple functions and wide application and can meet the comprehensive demands of the multiple-birth pregnant women and provide great convenience for the life, the medical examination and the transportation of the pregnant women.

A method for cultivating a new strain of Kenong mutton sheep, which relates to a method for cultivating a new strain of sheep. Small-tailed Han sheep are used as the female parent and Dorper sheep are used as the male parent to perform crossbreeding to obtain a first-generation hybrid sheep. Growth and development are the main selection indicators. After strict breeding, the selected Duhan first-generation ewes and small-tailed rams are used for crossbreeding to obtain the second-generation hybrids containing 1 / 4 Dorper sheep blood. The first-generation Duhan rams and Small-tailed Han sheep ewes are crossed, and the second generation of hybrids containing 1 / 4 Dorper sheep blood is also obtained. The basic ewes and rams are selected based on multiple births and meat traits, and cross-fixed, that is, A new strain of Kenong mutton sheep has been bred; the new strain of Kenong mutton sheep has slightly shorter legs than the Small-tailed Han sheep, has a large body, fast growth and development, high meat production rate, good meat quality, a reproductive rate of more than 220%, and strong adaptability , suitable for house feeding and development of fat lamb production.
