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 cows were examined, and 73 printedpictures were made
by using electronic printer (Mitsubichi,video-copy, AP 8600). The pictures
were separately studied andthe results analysed. From the 24 th day of
pregnancy we wereable to detect fetal water, and about 28th day it was
possible tofind orderly fetal water (black color) membranes and
embryo(white color). Our results in diagnosing were 98,4% occurate,which is
in agreement with the results of Reeves and ass. (1984),Pierson and Ginther
(1984), and Kanh (1985).
Keywords: Ultrasound, echo, echogram, pregnancy diagnosis, cow.

Summary: Forty-six mares mated from 16 to 58 days prior to
examination,were scanned using a linear-array ultrasound scanner (ALOHA
ECHOCAMERA SSD-210, DX II) with a 5 MHz transrectal transducer. For16
animals images were made on the thermopaper using anelectronic printer
(MITSUBISHI VIDEO COPY AP-8600). The pregnancydiagnosis was accurate in
100% of cases. The pregnancy wasdetected at the earliest period on the 16th
day, when theembryonic 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 pregnancystages our
estimation was based upon the foetal growth rate andposition of the foetus
and the foetal membranes.
Keywords: Ultrasound, mare, echo, echogram, early pregnancy diagnosis.

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: 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 150cows which were pregnant 18 days to 3 month, and on 47
mares,which have been mated 16-58 days before, and on the 66 goats,which
have been mated 30 to 70 day before examination. From 25 to28 day of
pregnancy in the cow it is possible to state a surediagnosis of pregnancy.
In the mare the sure signs of pregnancywere found on 24th to 25th day after
mating. It was describedchacing of position and shape of fetal membranes to
the 60th dayof pregnancy. Very sure and simply was to state diagnosis
ofpregnancy in the goats by transrectal transducer of 5 MHz beetwen30 to 40
days of pregnancy.
Keywords: Ultrasound, cow, mare, goat, echo, echogram, early pragnancy diagnosis.

Summary: Results of ultrasound pregnancy diagnosing in 103 cows,
whichwere pregnant from 21 to 57 days, were described. For 57 cows wehad
taken echograms for examination.It was established that from25th day of
pregnancy with transrectal transducer of 5 MHz, it issure possible to find
fetal membranes, fetal fluids and conturesof the fetus. Growing up of fetus
to the 6oth day of pregnancywas described, established by ultrasound method
of examination.

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.
Keywords: Cow, mare, ultrasound, ovaries, follicul, corpus luteum.
