Hoof morphometry of Santa Inês and Dorper sheep raised in Northeastern Brazil

Ciência Animal Brasileira
This study aimed to determine the hoof measurements in Santa Inês and Dorper sheep breeds, establishing a morphometric standard for evaluation. The thoracic (TL) and pelvic (PL) limbs from the right antimere of twenty male sheep, slaughtered at 30–35 kg ...

Exploring the Genetic Variation of Fleece and Crutch Shedding in Sheep, Recorded at Different Times Within and Across Age Classes

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The global value of wool from coarse woolled sheep continues to decline, prompting producers to seek alternatives that reduce or eliminate the need for shearing. Several sheep breeds naturally shed their fleece in response to photoperiod, and these breeds are being crossed with populations that have high genetic merit for traits such as ...

Associations between worm egg count and production in Dorper sheep [PDF]

, 2008
With changes to the Australian sheep industry, breeds that have a meat emphasis are becoming increasingly adopted by farmers. One such breed is the Dorper sheep, which was used in this study to investigate the relationship between worm egg count and ...

Genetic Correlations Between Fleece Shedding and Production Traits Indicate Minimal Trade‐Offs When Breeding for Maternal Shedding Sheep

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Fleece shedding is becoming an increasingly important trait in sheep production systems focused on meat and dairy, where wool has limited economic value and reducing shearing costs is desirable. For inclusion in breeding programmes, a trait must exhibit genetic variation, sufficient heritability, and have well‐defined relationships with other ...

Ventricular dyssynchrony as a cause of structural disease in the heart of Dorper sheep

Onderstepoort J Vet Res, 2004
Ventricular dyssynchrony is a disturbance of the normal, organized electromechanical coupling of the two ventricles. This condition has many causes, such as left bundle branch block, ventricular preexcitation, right ventricular pacing and right ventricular premature ventricular complexes (PVCs).

Estimates of Genetic Parameters for Ewe Longevity and Lifetime Reproductive Performance Traits in South African Merino Sheep

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Ewe's functional longevity impacts flock profitability by reducing annual ewe replacement costs and increasing ewe outputs over the production cycle. In this context, the main objective of this study was to estimate variance components and genetic parameters of five ewe longevity indicators in South African Merino sheep.

The heart remembers : observations of cardiac memory in the Dorper sheep heart

Onderstepoort J Vet Res, 2003
Memory is a property common to a diverse range of tissues. Cardiac memory has been demonstrated in the human, dog, rat and rabbit. This is a peculiar phenomenon, reflected in the T wave of the electrocardiogram. The heart is able to remember periods of alterations in the sequence of ventricular activation and once there is a return to a normal ...
