The Thai Journal of Veterinary Medicine

Neutral buffer formalin (NBF) has been widely used as a fixative for histological staining for ages. However, for some special staining, such as Masson trichrome staining, it has been proposed that the suitable fixative was Bouin’s solution. The purpose of the present study was to compare the different fixatives and post-fixative protocols on the quality of Masson trichrome staining. The canine intestines (n = 10), which were the duodenum and colon, were used as the candidate organs since they comprised of various tissue components. The fixatives and staining protocols were divided into four groups, which were Groups 1 and 2; …

Normal Thymus Evaluation Using Radiographs And Computed Tomographic Images In Young And Adult Dogs, Yoenhee Park, Sang-Kwon Lee, Sooyoung Choi, Hojung Choi, Youngwon Lee, Kija Lee

The Thai Journal of Veterinary Medicine

The thymus generally presents as a sail-shaped soft-tissue opacity on thoracic radiographs in young, pre-pubescent dogs. After puberty, lymphatic tissue is replaced by adipose tissue and can usually no longer be identified on radiographs; however, thymic remnants have often been observed in adult dogs. The objective of this retrospective descriptive study was to investigate the incidence of thymic remnants using thoracic radiographs and to analyze the incidence in dogs by age, sex and breed. We analyzed the data from 1,464 dogs that underwent both thoracic ventrodorsal and right lateral radiography, of which 40 underwent both radiography and computed tomography (CT). …

Teaser (Vasectomised) Rams : A Management Advantage, W L. Mcgarry, I. K. Stott

Journal of the Department of Agriculture, Western Australia, Series 4

WITH normal late spring-early summer matings (October-December) teaser rams, correctly used, will give a more concentrated lambing.

This has been shown under Western Australian conditions in trials conducted at the Wongan Hills Research Station.

In one experiment a group of 100 ewes which had one per cent, of teasers for 14 days before the fertile rams went in, dropped 42 lambs in the first two weeks of lambing, compared with 17 lambs from 100 ewes that were not teased.

The use of teasers in all Research Station flocks is now routine practice.
