Secretome profiling improves the pregnancy success rate of in vitro fertilization processes, while reducing the risk of multiple births.

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.

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.

The invention discloses a multifunctional handcart device convenient for conveying defecation of a pregnant woman, belonging to the technical field of medical apparatuses and instruments. Edema of lower extremity of some pregnant women with multiple births can not be relieved by using the traditional conveying tool, and oxygen uptake with a vehicle is very inconvenient. The technical scheme of the multifunctional handcart device is as follows: one end of a fine tuning gas tube (18) with an air feed and discharge switch (19) is fixedly connected and communicated with an extruding air inflation ball (17), the other end of the fine tuning gas tube (18) is fixedly connected and communicated with an air inflation tube joint (4), a small oxygen cylinder sleeve (20) is inserted on a pedal (2), two leg-placing grooves (16) are arranged on an inflation support and belly-supporting upright (1), two dovetail chutes (15) are respectively fixed on a base plate (6), and dovetail sliding plates (12) screwed with positioning bolts (14) are embedded on the dovetail chutes (15). The invention has the advantages of multiple functions, wide application, capability of meeting the complete demands of the pregnant woman with multiple births, and great convenience for life and medical inspection and conveying.
