Summarizing Applyment Technique Resear Chon B-mold Ultrasound Scanner In Modern Pig Production

Ultrasonography(USG),as one of the major content of veteritarian imaging technology,is a kind of clinical diagonosis method that has not issue lesion and radiative danger.A style,D style,M style and B style ultra diagonostic equipements were applied with different degree in veteritarianary domain following Lindahl has used it in the diagonosis of sheep gestation pregnancy.Our country is developing cultivation industry vigorously,especially raising pigs,enlarging and increasing the propagation and amount ofpig is the priority. Inveteritarian B-mold ultrasound scanner detecting is effective means,it can improve propagative efficiency.The research and applyment on inveteritarian B-mold ultrasound scanner testing technique in developed countries.Ultrosonic diagonostic technique is applied late in our country,every techinique links are expecting improvement,especially the detectin means need be improved.The inveteritarian ultrasonic began in in the late time of 1970',it majorly drew lesson from human medicine.A and D style Ultrasonic were the most important styles at that time,majorly being used to diagnose gestation investigate,pork dorsal fat Measuring Backfat Thickness.In the early time of 1980',B and M style were applied in inveteritarian clinic,for example having the detecting of artificial Bezoa and the research on Eehoeardiography of Buffalo.After that,the inveritarian ultrasonic diagonology made much progress in disease diagonosing,gestation investigate and gackfat Thickness measurement.In our country,part of the units raising pigs have inveterian B-mold ultrasound scanner which is onlty limited to diagonose Early pregnancy and can't do multi-link detection.It is one of the reason which both is disadvantageous to the enough use and leas to the low productive efficiency.Not having been applied in more links for B-mold ultrasound scanner is limited by the unmaturity of the detecting technique which has not reference data.So applyment basis of B-mold ultrasound scanner detecting technique need be improved.The experiment selected pigs as subject,did B-mold ultrasound scanner detection to identification of estrus ovulation,identification of first trimester pregnancy,fetus number,fetus activity,and expected to grope systymatic,perfect detecting technique and parameter,then reference data used to direct producting practice,got the objective of increasing offspring number of adult female pig and productive efficiency.We had the following experimental contents:1,the research on Estrous of pig and ovalating identification,probe the genital organs change during Estrous,majorly research the B-mold ultrasound scanner detecting technique of uterous and ovary during Estrous ing,detect follicle development and ovulation time,offer scietific foundation for timely hybridization.2.The B-mold ultrasound scanner detecting technique research on earlier gestation pregnancy,is majorly the diagonosis of pig earlier gestation pregnancy preventing from misalliance;3.the vitality detecting technique research on of fetus during earlier gestation pregnancy,adopt necessary measures timely preventin from dead fetus and abortion.4 the B-mold ultrasound scanner detecting technique research on the mechnism recovery of uterous and ovary,judge the recovery condition of after in labor uterous and ovary,increase female pig productive ability.5.the establish and research of reference critirion of B-mold ultrasound scanner photomap,do some tentative research of B-mold ultrasound scanner photomap to different embryo age,expect to grope systimatic and perfect B-mold ultrasound scanner detecting technique and parameter,and make reference data.We draw the following conclusions:1,the identifacation of estrus ovulation offered scientific foundation for timely hybridization,decreased misalliance,increased conception rate largely;2,the diagonosis of Early pregnancy,decreased non-pregnant at the lowest limitation.3.B-mold ultrasound scanner photomap detection to different age and the B-mold ultrasound scanner determination reference data establish are of much significance to directing producting practice of raising pigs.4.B-mold ultrasound scanner detecting technique research on mechnism recovery of uterous and ovary,made accurate judgement to the recovery condition of uterous and ovary and diseases appearance.The result showed B-mold ultrasound scanner has much applying space in raising pigs,the B-mold ultrasound scanner all time detection is of much significance to improve productivity,especially the reproductive ability.
