| From 2006 a lot of domestic swines, cattle and sheep breeding production units have purchased China-made high quality and low price veterinary super-B equipment, and gradually in production applications. But our country has so far only a handful of veterinary colleges and universities to open B-elective curriculum, no professional veterinary B materials and ultra-sound B-veterinary references. At present the majority of aquaculture units B-veterinary larger technical problems still exist, the majority is also limited to the diagnosis of pregnancy, there is no comprehensive veterinary B-exert all application functions. Our country is making great efforts to develop aquaculture, swine bearing the brunt of the expansion as soon as possible, enhance the9+ volume of swine breeding and its population has become a top priority, veterinary Detected B-are effective means to dramatically improve the efficiency of swine breeding. Our step-by-step according to the actual situation should be to promote the use of B--universal, which use of the knowledge, take this opportunity to put it as the promotion of scientific and technological progress, improve the level of our country veterinary technology ladder.In this study, selection of adult sows as research subjects, their early pregnancy diagnosis, reproductive disease detection, identification of fetal vitality of the entire process such as B-monitoring, with a view to explore a set of systematic and well-swine B-monitoring techniques and parameters, at This basic reference on the preparation of maps used to guide the production practice to improve the rate of sows farrowing and production benefits. Tests were carried out the following elements: 1, pigs early pregnancy monitoring the B-technology research, mainly carried out on the child-bearing age sow early pregnancy diagnosis in order to prevent air-huai, reduce feeding invalid; 2, B-Pig different image for gestational age reference standards and research, through the different gestational age for B-Pig, with a view to explore a set of systematic and well-Pig B-monitoring techniques and parameters and to prepare a reference map. 3, sow reproductive system diseases of B-detection technology and image research, the use of B-on a variety of uterine, ovarian disease-related reproductive monitoring, to identify the uterus, ovary disease, a typical image in order to guide prevention and treatment of these diseases . 4, During pregnancy and fetal of sows viability detection technology research, timely take the necessary measures to prevent the occurrence of still births and abortions; 5, pig back fat, eye muscle thickness and area measurement, using B-vivo monitoring of pig back fat and eye muscle area.Test form to the following conclusions: 1, through early pregnancy diagnosis, diagnostic accuracy was high, at least, the reduction of air-huai's happened, and less rearing invalid improve economic efficiency; 2, piglets of different gestational age for B-image of the monitoring, the development of the whole B-Pig monitoring techniques and reference maps for guiding the practice of pig production has important significance; 3, through a variety of uterine, ovarian disease monitoring and pig uterus, ovarian function recovery of B-monitoring technology research on a variety of uterine, ovarian disease make accurate judgments, provide guidance for the prevention and treatment. 4, through the in vivo of pig back fat, eye muscle thickness and area measurement, guidance breeding breeding work.The experimental results show that: Veterinary B-in swine production has a broad application space, and through the B-the full monitoring, to improve pig productivity and economic benefits, especially improve sow fertility has important significance, is worth popularizing. |
