Antibiotics And The Wasting Disease In Neonatally Thymectomized Rats, Douglas M. Grignon
Antibiotics And The Wasting Disease In Neonatally Thymectomized Rats, Douglas M. Grignon
Loma Linda University Electronic Theses, Dissertations & Projects
The administration of the antibiotic, Chloramphenicol, to pregnant rats just prior to, and for four days after delivery, diminishes the incidence of the so-called "Wasting Disease" in neonatally thymectomized rats.
A total of 50 rats were divided into the following groups:
- Thymectomy only---nonmedicated 17 rats
- Thymectomy only---medicated 12 rats
- Thymectomy-adrenalectomy---nonmedicated 5 rats
- Thymectomy-adrenalectomy---medicated 8 rats
- Controls---nonmedicated 4 rats
- Controls---medicated 4 rats
Chloramphenicol was administered in the drinking water to the mothers of groups 2, 4 and 6 for about 2 days prior to delivery and 4 days after. On the day of birth or within three days after birth, the …

Sheep Breeding Problems In W.A. : The Industry's View, Stanley M. Dennis
Journal of the Department of Agriculture, Western Australia, Series 4
IN 1963 a short questionnaire was distributed to farmers and pastoralists seeking information about sheep breeding problems and lamb losses.
This was a fore-runner to the Department of Agriculture survey into the causes of abortion and lamb mortality which is reported elsewhere in this issue.

How To Identify Twin-Born Lambs, G T. Halpin, P. Nelson
Journal of the Department of Agriculture, Western Australia, Series 4
IN the past few years it has become widely accepted that the ability to produce twin or multiple lambs is a heritable characteristic.
This means that breeding from sheep born as twins should give more multiple births and higher lambing percentages than breeding from sheep born as single lambs.

Dead Lambs : A Dead Loss, Stanley M. Dennis
Journal of the Department of Agriculture, Western Australia, Series 4
During the past year the Animal Health Laboratory has continued its survey into the causes of abortion in sheep and perinatal lamb losses.
This article records the results of this work.
LAMBS and specimens from lambs were submitted to the Animal Health Laboratory from 229 properties situated in 121 areas in this survey during 1964.
Post-mortem examination was carried out on 1,422 lambs and specimens from 61 lambs were also examined.
