Coat Color‐Associated Transcriptomic Differences of Black and White Hortobágyi Racka Sheep Using the RNA‐Seq Technique

Ecology and Evolution, Volume 16, Issue 10, October 2026.
We compared skin transcriptomes of black‐ and white‐coated Hortobágyi Racka sheep using RNA‐seq to identify coat color‐associated molecular differences. Black‐coated sheep showed coordinated upregulation of melanogenesis and melanosome‐related genes together with pathways linked to redox balance, mitochondrial metabolism, and thermogenesis.

Shedding Shearing Costs: Developing a Self‐Shedding Flock Through a Romney × Wiltshire Crossbreeding Programme

New Zealand Journal of Agricultural Research, Volume 69, Issue 5, October 2026.
A long‐term study was started in 2020 to monitor the transition of a Romney‐based flock to a fully‐shedding flock as a potential strategy to reduce shearing costs. Romney ewes (n = 400) were bred to Wiltshire rams, alongside a control group of Romney ewes (n = 200) bred to Romney rams.

Genetic Polymorphism of Growth Hormone Gene in Dorper Sheep using PCR-RFLP

Indian Journal of Animal Research
Background: The growth hormone gene has a significant impact on postnatal longitudinal growth and development as well as the metabolism of protein, carbohydrates, and fats moreover its effects indirectly relate to bone and skeletal development.

Genetic structure of South African Nguni (Zulu) sheep populations reveals admixture with exotic breeds.

PLoS ONE, 2018
The population of Zulu sheep is reported to have declined by 7.4% between 2007 and 2011 due to crossbreeding. There is insufficient information on the genetic diversity of the Zulu sheep populations in the different area of KwaZulu Natal where they are ...
