Association analysis of GHR gene polymorphism with growth traits in sheep

Indian Journal of Animal Sciences, 2022
In this study, polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was employed to investigate the polymorphism of GHR gene and the correlations of polymorphic sites with growth traits.

Adaptive and Productive Sheep Breed for Changing Climate

Proceedings, 2020
Sheep in semi-arid environments are likely to be affected by warming environment due to climate change. To identify genotypes best suited to warmer climates we assessed thermotolerance and meat quality of 5 female sheep of each of 4 breeds (Merino ...

Factors associated with the reproductive performance of ewes inseminated laparoscopically in England and Wales: A longitudinal study

Veterinary Record, Volume 199, Issue 1, Page e21-e29, 4/11 July 2026.
Abstract Background Laparoscopic intrauterine artificial insemination (Lap‐AI) is used in sheep genetic improvement programmes. However, the lambing rate (LR) (i.e., the proportion of inseminated ewes that lamb) following Lap‐AI is variable. Previously, one small UK study investigated factors associated with LR, but it did not adjust for dependencies ...

From Assessment to Optimization: A Comprehensive Review of the Mutton Quality Evaluation Index, Factors, and Improvement Strategies

Food Frontiers, Volume 7, Issue 3, May 2026.
This graphical abstract summarizes the comprehensive framework of mutton quality, including evaluation indices, influencing factors, and improvement strategies. Meat quality is systematically assessed through multiple dimensions, including flavor, color, pH, tenderness, water‐holding capacity, intramuscular fat, and nutritional composition.

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).

Effect of Diet Neutral Detergent Fibre Content on Dry Matter Intake, Nutrient Digestibility, Growth Efficiency and Carcass Characteristics of Finishing South African Mutton Merino Wether Lambs

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Feeding South African Mutton Merino lambs low‐NDF lucerne hay diets improved nutrient digestibility, energy utilisation, growth efficiency, and carcass quality. Despite lower intake at the lowest NDF level, fibre digestibility and feed conversion improved, indicating that highly digestible, low‐NDF finishing diets enhance lamb growth and carcass traits.

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 ...

Moringa stenopetala Leaves and Cafeteria Leftover as Nonconventional Supplements in the Diets of Local Gamo Sheep: Nutrient Utilization, Growth Performance and Economic Efficiency

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
For smallholders having plenty of cafeteria leftovers and M. stenopetala leaves, blended feeding of the ingredients is more profitable than their exclusive feeding. Provided that they are comparably available, sole supplementation of M. stenopetala is more advantageous and profitable than sole supplementation of cafeteria leftovers.
