DNA study offers fresh insights into pig muscle growth
The findings could be used to predict muscle growth in developing pigs.
Researchers hope their findings will help to support breeding selection programmes.

New research revealing insights into pig muscle development could lead to new tools to inform breeding selection.

The findings are published in G3: Genes, Genomes, Genetics by a team from the Roslin Institute and the Centre for Tropical Livestock Genetics and Health.

In the study, researchers analysed DNA in frozen tissue samples from muscle in piglets at various stages of development. Through this, they were able to pinpoint regions of DNA that control activity in genes linked to muscle growth and study activity in these genes. 

The scientists noted variations in regions of DNA between small and large piglets, suggesting a difference in how DNA is regulated, which subsequently governs muscle growth between large and small piglets. 

It is hoped the findings could help to predict muscle growth in developing pigs, to produce litters with fewer very small piglets. The improved knowledge could also underpin research into other areas of pigs' development, health and welfare.

Looking ahead, the team hopes to identify variations in the genetic code of pigs associated with growth and better understand how these differences regulate the activity of genes involved in muscle development to inform pig breeding programmes.

They also hope to apply their method of analysing frozen tissue to investigate how the genetic code of livestock controls their characteristics. The use of frozen tissues samples can also help to limit the number of animals used for research. 

Dr Emily Clark, from the Roslin Institute, explains: “Pigs are widely farmed and it is important that we understand their biology, including detailed knowledge of their genetic code. Our findings help to improve understanding of the pig genome and will support further research to aid breeding selection programmes.”

New roadshow brings free flea and tick checks to dog owners

News Story 1
 A nationwide roadshow offering free, personalised parasite risk assessments and flea and tick checks will be visiting popular dog events across the UK.

The All About Dogs shows in Norfolk and Knebworth, will be among the first events to host MSD Animal Health's Big Parasite Check campaign, which aims to address common misconceptions and highlight the importance of year-round parasite protection.

A total of six dog-friendly events will feature the free clinics from summer through to winter. Full roadshow dates and locations are available on The Big Parasite Check map or through your local MSD Animal Health Representative.

BVA urges 'continued vigilance' over bluetongue

The British Veterinary Association (BVA) has urged vigilance following a concerning rise in Bluetongue (BTV) cases in sheep and cattle.

In a recent statement, the BVA noted that members are reporting more severe clinical signs and higher mortality rates than in previous years.

'We know that farm vets are working hard to support farmers and animals affected by this outbreak, during what is an extremely difficult time for all involved,' they stated. 'Continued vigilance to identify disease early is vital and vaccination remains the best way of protecting animals from this disease.'
