Immunization of sheep against GnRH early in life: effects on reproductive function and hormones in ewes

Autor: B W, Brown, P E, Mattner, P A, Carroll, R M, Hoskinson, R D, Rigby

Publikováno v: Reproduction. 103:131-135

Groups of Merino ewe lambs were immunized against GnRH either soon after birth (prepubertal) or around puberty (peripubertal) with a prototype commercial preparation and were studied over the following 2 years to determine the long-term effects on re

Formation and retention of the spermatozoan reservoir in the cervix of the ruminant

Autor: P. E. Mattner

Publikováno v: Nature. 212(5069)

IN ruminants, the cervix has an important role as a reservoir from which migration of spermatozoa to the uterus arid Fallopian tubes continues for a prolonged period after mating1,2. To ensure that an adequate population of gametes is established in

Autor: BD Gream, RL Honnery, G. H. Brown, P. E. Mattner, B. W. Brown, B. A. Panaretto

Publikováno v: Australian Journal of Agricultural Research. 41:1147

Seminal characteristics and flock fertility were studied in Merino rams treated with mouse epidermal growth factor (EGF). Intravenous infusions of 105 8g EGF/kg body weight over 24 h in five rams had no statistically significant effect on daily sperm

MEASUREMENTS OF ENDOMETRIAL BLOOD FLOW IN ANAESTHETIZED EWES BY XENON-133 CLEARANCE AND MICROSPHERE TECHNIQUES

Autor: P. E. Mattner, B. F. Hutton, Ian S. Fraser, B. W. Brown

Publikováno v: Quarterly Journal of Experimental Physiology. 67:531-535

In six anaesthetized, non-pregnant ewes, uterine blood flow rates measured by monitoring the clearance of xenon (133Xe) from the lumen of the uterus were compared with estimates of endometrial and myometrial capillary blood flow obtained by the use o

Publikováno v: Reproduction. 79:315-324

Groups of bull calves received a primary immunization against testosterone (Group T; N = 7) or oestradiol-17 beta (Group E; N = 9) at 3 months of age and booster injections on four occasions at approximately 2 month intervals. Controls (Group C, N =

Ovarian arterial blood velocity measured with Doppler ultrasonic transducers in conscious ewes

Autor: M. J. Emery, P. E. Mattner, B. W. Brown

Publikováno v: Reproduction. 58:295-300

Summary. Changes in the mean velocity of ovarian arterial blood flow during the oestrous cycle were monitored in 5 ewes by the use of Doppler ultrasonic transducers chronically implanted around the ovarian arteries. In arteries supplying ovaries with

CAPILLARY BLOOD FLOW IN THE GENITAL TRACTS OF CONSCIOUS EWES: CYCLIC CHANGES AND THE EFFECT OF OVARIAN HORMONES

Autor: P. E. Mattner, B. W. Brown

Publikováno v: Journal of Endocrinology. 74:185-191

The indicator fractionation technique with [86Rb]rubidium chloride as the indicator was used in conscious animals to determine the relative blood flow (RBF) as a measure of capillary blood flow in regions of the genital tract of cyclic ewes and of ho

Autor: P. E. Mattner

Publikováno v: Reproduction. 17:253-261

Quantitative studies were made of the distribution of spermatozoa and leucocytes in the female genital tract of mated goats and cows near the time of ovulation and of the leucocytes in the genital tract of unmated goat does at a similar time. In both
