Spring 1 influence to replacement gilt health status and production performance of grain of the invention of table 2.

P2 point back-fat thicknesses and P2 point back-fat thicknesses during third time heat during firstly, for sow body weight and first heat These three indexs, the numerical value of control group is significantly higher than common group and test group (P<0.05), but between common group and test group It is not significantly different (P ＞ 0.05).Result above shows that universal grain and spring grain of the invention can be efficiently controlled The body weight and back-fat thickness (the bacon hogs bodily form more standard, be more suitable for reserving seed for planting) of replacement gilt.

Secondly, having in control group has a sow morbidity in three sow morbidities, common group, but does not have sow in test group Morbidity.Result above shows, grain of the present invention, either universal grain or spring grain, although do not add extraly Antibiotic, but the sub-health state of replacement gilt can be effectively repaired, effectively improve its immunocompetence.Also, from these As a result it can also be seen that the spring grain of the present invention for sow sub-health state and improves its immunocompetence aspect after repair, Effect is better than universal grain of the invention, but difference between the two is not notable.

Again, mammiplasia is bad in control group and the hypogenetic sow quantity of vaginal orifice is apparently higher than common group (P< 0.05) with test group (P<0.01).In addition, in age of first estrus, second of inter oestrual period and third time inter oestrual period side Face, common group significantly shortens (P compared with control group<0.05), the time has been respectively shortened 2.4 days, 3.7 days and 3.5 days, and test group compared with Control group is extremely significantly reduced (P<0.01), the time has been respectively shortened 5.6 days, 6.9 days and 6 days.

Finally, compared with control group, common group (P<0.05) mortality with test group significantly reduces (P<0.01), divide 3.3% and 10% are not reduced.

Summer grain 1, autumn grain 1 and winter grain 1 also obtain the effect similar with spring grain 1.

Result above shows that, relative to the replacement gilt grain commonly used on Vehicles Collected from Market, seasonal form grain of the present invention is same Universal grain is the same, can also promote mammogenesis, promotes the development and ovulation in ovary and uterus, protects birth canal, promotes female Pork chop ovum heat shifts to an earlier date, and shortens the oestrous cycle, improves breeding rate, extends the service life of sow.Also, the skill of seasonal form grain Art effect more preferably becomes apparent from relative to universal grain.

To sum up, grain of the present invention, including universal grain and seasonal form grain, contain a variety of nutriments due to it, match somebody with somebody Fang Kexue, comprehensive nutrition, therefore the basal nutrient of replacement gilt can be fully met, it ensure that the speed of growth of replacement gilt It is moderate, it is ensured that its quality.Although in grain of the present invention and any chemical synthetic drug and antibiotic are not added with, but can Its disease resistance is improved by improving the immunocompetence of replacement gilt itself, the inferior health body of sow is repaired.In addition, of the invention Grain can promote the development of replacement gilt reproductive system, shorten between heat first and second and the time of third time heat Every the production performance of raising replacement gilt.Finally it should also be noted that grain of the present invention can reduce the mortality of replacement gilt, Improve its utilization rate.

Finally it may be noted that as well known in the art, replacement gilt is similar with both nonpregnant sows Physiological stage, therefore those skilled in the art can have positive face with rational expectation to health, production performance of replacement gilt etc. Loud grain of the present invention is equally applicable to nonpregnant sows.

With reference to the explanation of the invention disclosed here and practice, other embodiment of the invention is for those skilled in the art It all will be readily apparent and understand.Illustrate and embodiment is to be considered only as exemplary, of the invention true scope and purport is equal It is defined in the claims.
