    Summary: A linear-array ultrasound electronic scanner with a transrectal 5MHz transducer was used for early pregnancy diagnosing in thecows pregnant between 18 and 58 days. More than 100 pregnant cowswere examined, and 73 printed pictures were made by usingelectronic printer (Mitsubichi, video-copy, AP 8600). Thepictures were separately studied and the results analysed. Fromthe 24th day of pregnancy we were able to detect fetal water, andabout 28th day it was possible to find orderly fetal water (blackcolor) membranes and embryo (white color). Our results indiagnosing were 98.4% occurate, which is in agreement with therusults of Reeves and ass. (l984), Pierson and Ginther (l984) andKahn (1985).
    Keywords: Ultrasound, echo, echogram, pregnancy diagnosis, cow.

    Summary: Investigations on the efficiency of the superovulation and superovulatory response and the number of recovered embryos and also the transfer results of fresh and cryopreservated/thawed bovine embryos were performed on 35 females. Superovualtion was induced using PMSG (Folligon) or FSH (Folltropin) preparations in 27 females. The results of the superovulation and superovulatory response on the day 7 after induced ovulation and A.I. were followed up by rectal and ultrasonographic examination of the ovaries (Aloha Echo Camera SSD-210, DX II with 5 MHz transrectal transducer) and 154 (X=5,70 + 0,69) corpora lutea were established. In 23 females a total of 15 embryos were received and 10 embryos were classified as transferable and then one embryo was instantly transferred into the selected recipient. The other 9 embryos were cryopreservated using freezing machine (Le Nicoobac MS 21). After some time embryos were thawed and following classification 7 were transferred into 7 synchronized recipients. In 3 recipients estrus reappeared after 25 days, in one after 30 days, and in 3 recipients 35 day after the previous estrus, whereas the pregnancy was ultrasonically established in one recipient on the 34th day.

    Summary: Superovulation was induced using PMSG or FSH preparations in 29 cows and heifers, aged 12 months to 12 years. The results of the superovulation treatment were evaluated at the same time of insemination, first by rectal and then by ultrasonographic examination of the ovaries. The superovulatory responses of the ovaries were followed on the Day 7 after induced superovulation and artifical insemination using rectal examination and ultrasonography. In 26 from 29 females corpora lutea were established on the ovaries and embryos were collected using PBS medium and the method of gravitation and aspiration. Total number of 13 embryos were received and after ovulation at 50% magnification, the 8 high quality embryos were separated and finally, edding the trening medium, separated in strows. The controlled freezing procedure of bovine embryos was accomplished in the freezing machine "LE NICOOLBAC MS 21" and cryopreservated embryos were plunged and placed into liquid nitrogen. Prior to transfer in preparated recipients, strows containing embryos were thawed by a special procedure. Embryos were ovulated again at under magnification and 7 embryos were transffered in 7 recipient cows, on the Day 7 after oestrus. In 3 recipients oestrus was observed 25 days after embryo transfer but in one recipient after 30 days and therefore we consider it as a result of the early embryonic death.

    Summary: Forty-six mares, which were mated from 16 to 58 days prior to examination, were scanned using a linear-array ultrasound scanner (ALOHA ECHO CAMERA SSD-210, DX II) with a 5 MHz transrectal transducer. For 16 animals images were made on thermopaper, using an electronic printer (MITSUBISHI VIDEO COPY AP-8600). The pregnancy diagnosis was accurate in 100% of cases. The pregnancy was detected at the earliest period on the 16th day, when the embryonic vesicle with embryonic fluid was seen on the screen. From the 24th and 25th day, besides embryonic vesicle with fluid, we observed an embryo within the vesicle. In later pregnancy stages our estimation was based upon the foetal growth rate and positon of the foetus and the foetal membranes.

    Summary: Results of investigation about possibilities to state earlydiagnosis of pregnancy in the cows, mares and goats weredescribed by using ultrasound transrectal transducer of 5 MHzwith special scanner for echography, and electronic printer formaking echograms. Investigations were performed on the 150 cowswhich were pregnant 18 days to 3 months, and on 47 mares, whichhave been mated 16 to 58 days earlier, and on 66 goats mated 30to 70 days prior to examination. From 25 to 28 days of pregnancyin the cow it is possible to state a sure diagnosis of pregnancy.In the mares the sure signs of pregnancy were found on 24th to25th day after mating. It was described changing of position andshape of fetal membranes to the 60th day of pregnancy. Very sureand simply was to state diagnosis of pregnancy in the goats bytransrectal transducer of 5 MHz beetwen 30 to 40 days ofpregnancy.

    Summary: Results od ultraound pregnancy diagnosing were described in 103cows, which were pregnant from 21 to 57 days. For 57 cowsechograms were printed during examination. It was establishedthat from 25th day of pregnacy with transrectal transducer of 5MHz, it is sure possible to find fetal membranes, fetal fluidsand contures of the fetus. Growing up of fetus to the 60th day ofpregnancy was described, established by ultrasound method ofexamination.

    Summary: By using ultrasonic device (Aloha Echo Camera SSD-210 DXII) and transrectal transducer of 5 Mhz we made 60 searches of ovaries in the mares and 90 in the cows and heifers. During searching all interesting pictures were printed by using electronic printer (Mitsubishi Video Copy AP 8600), for later analysis. We were interested for all physiological changes on the ovaries during sexual cycle, and specially during proestrus and estrus. Diameter of follicle in the cows and heifers which we could see was 4 to 18 mm. Diameter of follicles during estrus or ovulation was 14 to 18 mm. Corpus luteum was possibly to see and represent from 3rd to 5th day of sexual cycle to the new estrous. In the mares corpus luteum was possibly to detect when they have diameter of 3 mm, and later during sexual cycle, and specially before ovulation it is very easy to diagnosing them and measured by ultrasonic device. Then diameter of follicles is 4 to 7 cm, and on the basis of its size it is possible to determine optimal time for insemination or mating of mares. Determination of ovulation time by ultrasonic control and by repetition of mating or A.I. it is possible to get maximal results of pregnancy in the mares and cows.
