Post-weaning diarrhoea in piglets remains an important cause of economic losses for swine producers. Feed supplementation with probiotics is one of the alternatives to antibiotics used to reduce the impact of such gastrointestinal disease. The aim of the present study was to evaluate the effect of Ligilactobacillus salivarius PS21603 supplementation on the intestinal structure and the gut microbiota composition of weaned piglets.

- The genome sequence of strain UTPV1/AB, part of the species UTPV1, is reported.
- This strain was isolated in eastern Ireland from a nasal swab of a beef-suckler calf.
- The calf was diagnosed with bovine respiratory disease on a farm located in County Meath.
The present study aimed to characterise properties of the strain PS21603 and evaluate piglets' tolerance for its use as feed additive in swine. The ability of PS21603 of inhibiting enteropathogens' growth was evaluated using a co-culture assay. Low pH tolerance, bile tolerance, and resistance to osmotic changes were evaluated.

- 24 bovine coronavirus (BCoV) genome sequences were obtained from samples in Ireland.
- The virus was specifically sequenced from nasal swabs taken during an outbreak of bovine respiratory disease (BRD).
- The affected animals included recently purchased beef suckler and pre-weaned dairy calves.
Article Synopsis
- Bovine respiratory disease (BRD) significantly impacts calf mortality in Ireland, with one-third of deaths in 1-to-5 month-old calves attributed to it, revealing limitations in clinically diagnosing BRD based solely on observable respiratory signs.
- A study involving 53 male dairy calves found that while 43% showed clinical BRD symptoms, 64% had detectable lung lesions through ultrasonography, often preceding clinical signs by over ten days.
- Despite the presence of BRD, overall growth rates (average daily weight gain) did not significantly differ between calves with and without clinical signs, but those with severe lung lesions experienced reduced growth compared to healthy calves.
