Genomic Analysis of Hair Sheep From West/Central Africa Reveals Unique Genetic Diversity and Ancestral Links to Breed Formation in the Caribbean

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Cameroon Blackbelly sheep are a domestic breed of hair sheep from West/Central Africa. They are popular with small‐holder farmers in Cameroon as they are highly resilient to local environmental challenges and are prolific a‐seasonal breeders.

Genomic selection in practice in French Lacaune dairy sheep

, 2018
International audienceThe breeding organizations of the Lacaune dairy sheep introduced genomic selection in 2015. Results from the first crop of daughters from genomically selected rams confirm its efficiency: after a genomic selection proportion of 1/3 ...

Energy Intake During the Transition Period Triggers Substantial Impacts on Body Weight, Milk Production Efficiency, Milk Composition and Blood Biochemical Constituents in Fat‐Tailed Ewes

Veterinary Medicine and Science, Volume 11, Issue 6, November 2025.
The nutritional management during the transition period is crucial for sheep. This research highlighted a significant association between the energy intake of ewes and various factors, including their body weight, milk production and composition, production efficiency, as well as key blood biomarkers indicative of the metabolic status of the animals ...

Eprinomectin pour-on (EPRINEX® Pour-on, Merial): efficacy against gastrointestinal and pulmonary nematodes and pharmacokinetics in sheep

BMC Veterinary Research, 2017
Background The anthelmintic efficacy of the 0.5% w/v topical formulation of eprinomectin (EPN), EPRINEX® Pour-on (Merial) when administered at 1 mg/kg body weight was evaluated in sheep in two dose confirmation laboratory studies and one multicenter ...

Estimation of genetic parameters for production, composition and processability of milk from dairy sheep in a New Zealand flock

New Zealand Journal of Agricultural Research, Volume 68, Issue 5, Page 1107-1124, October 2025.
ABSTRACT This paper aimed to estimate the heritability and genetic correlations for processability (milk coagulation properties, cheese yield, and heat stability), milk production, and milk composition of dairy sheep in a New Zealand flock. Test‐day records from 169 ewes were obtained during the 2021–2022 season. Heritability estimates for yield traits

One polymorphism at the Stearoyl CoA Desaturase (SCD) gene is associated to CLA content of sheep milk fat

Italian Journal of Animal Science, 2010
On OAR 22 a highly significant QTL affecting the rate of desaturation of vaccenic acid (VA) to conjugated linoleic acid (CLA) in the mammary gland of sheep was found segregating on four dairy sheep families of a Sardinian x Lacaune back-cross population.

Genomic selection strategies for the German Merino sheep breeding programme – A simulation study

Journal of Animal Breeding and Genetics, Volume 142, Issue 3, Page 251-262, May 2025.
Abstract Genomic selection is widely implemented in livestock breeding programmes across species. Its potential is also evident for sheep breeding; however, it has several limitations, particularly because of the high genetic diversity across and within sheep breeds. In Germany, the predominant sheep breed is the Merino sheep. Until now, there has been

Cut‐off value of somatic cell count and validation of differential somatic cell count by the fluoro‐optical method in subclinical mastitis milk in three sheep breeds

International Journal of Dairy Technology, Volume 78, Issue 2, April–June 2025.
For the first time, the DSCC fluor optic method was validated for sheep milk. Optimal cut‐off values of SCC and DSCC were calculated for three dairy sheep breeds. Somatic cell count (SCC) is a test used for mastitis control in ewes, but there is no consensus on the cut‐off value.
