Blood indices of sheep fed with ensiled signal grass (Brachiaria decumbens)

New Zealand Journal of Agricultural Research, Volume 68, Issue 7, Page 1985-2002, December 2025.
ABSTRACT The Brachiaria species, particularly B. decumbens, is a key ruminant feed in the tropics but contains steroidal saponins that may cause toxicity, raising concerns for small ruminant farmers. Eighteen 6‐month‐old sheep were randomly assigned to three treatments over a 90‐day feeding trial: Negative control (fresh P.

Dermatosparaxis in White Dorper sheep.

Journal of the South African Veterinary Association, 1988
A diagnosis of dermatosparaxis in a lamb with clinical signs of extreme skin fragility was based on the gross changes as well as on light and scanning electron microscopical observations. Similar cases had occurred on the same farm during the previous year.

Morphofunctional characteristics of Dorper sheep crossed with Brazilian native breeds

Small Ruminant Research, 2019
Abstract The relationship between body development and external measures in sheep could provide useful information to define the optimal slaughter time as well as the adequate nutritional management. Thus, the objective of this study was to evaluate the morpho-functional diversity of Dorper sheep crossed with Brazilian native breeds using in vivo ...

Avermectin-resistance in gastrointestinal nematodes of Boer goats and Dorper sheep in Switzerland [PDF]

Veterinary Parasitology, 2007
Anthelmintic resistance in gastrointestinal nematodes among small ruminants is widespread in South Africa and Dorper sheep and Boer goats have been imported into Switzerland from this country on a number of occasions. Therefore, this study aimed to investigate the occurrence of avermectin (AVM) resistant gastrointestinal nematodes (GIN) in these breeds

Genomic Insights Into the Body Size Evolution in Mustelidae (Mammalia: Carnivora)

Ecology and Evolution, Volume 15, Issue 10, October 2025.
The comparative genomic analysis of 19 mustelid species provides insights into the genetic basis of body size evolution, identifying candidate genes and pathways under selection that underlie the remarkable morphological diversity in Mustelidae. ABSTRACT The extraordinary body size diversity within Mustelidae makes this carnivoran family an exceptional
