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 ...

First Report of Anthelmintic Resistance in Gastrointestinal Nematodes of Sheep from Costa Rica

Veterinary Medicine International, Volume 2011, Issue 1, 2011., 2011
As the prevalence and severity of anthelmintic resistance continue to rise, nematode infections in sheep correspondingly reduce the profitability of the sheep industry. In Costa Rica, sheep production systems are increasing in both number and importance.

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.

Characterization of Gastrointestinal Parasites in Grazing Sheep in Mountain, Piedmont, and Savanna Conditions of Casanare, Colombia

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
Gastrointestinal parasitosis represents a significant constraint on sheep productivity in Colombian tropical production systems; however, their regional epidemiological dynamics remain insufficiently characterized. Therefore, the objective of this study was to characterize the prevalence, associations, coinfestations, and health‐related correlations of

Non‐Invasive and Low‐Cost Approach for Estimating Sheep Weight Using Computer Vision

Engineering Reports, Volume 7, Issue 8, August 2025.
Non‐invasive sheep weight estimation system using a Kinect V2 sensor, integrating EfficientNetB3 for frame selection, U‐Net for segmentation, and CNN‐based feature regression for weight prediction. The ensemble model achieved an RMSE of 3.43 kg and R 2 of 0.89, improving accuracy and reducing animal stress.
