From Research to Reality: Making Sense of Probiotics in Sheep Systems Dr Joss West
Slide 2: Who Am I?
WHO AM I? • Veterinarian working across ruminant systems • Strong interface between science and commercial production • Lived experience alongside nutritionists and producers Dr Joss West Chief Operating Officer, Terragen Biotech
Slide 3: My Journey with Probiotics
MY JOURNEY WITH PROBIOTICS I spent years studying “bad bacteria”.. I had questions! Do probiotics actually work? How do they work? Why do results vary between animals, diets and production systems? I wanted solutions to improve rapid diet transition s initially. This is how my work with Terragen sta
Slide 4: What Are Probiotics?
WHAT ARE PROBIOTICS? Probiotics (or direct-fed microbials) by definition are live microorganisms selected to deliver a benefit to the host - through support rumen function, animal health, and/or feed efficiency. • Prebiotics – food for beneficial microbes • Probiotics – the beneficial microbes • Pos
Slide 5: Sheep Are Not Little Cows
SHEEP ARE NOT LITTLE COWS Sheep and cattle are both ruminants, but the way they eat, digest and respond to supplementation is different. We often adopt cattle learnings, but sheep systems are fundamentally different: Grazing-dominant | Variable intake patterns Different rumen dynamics Why this matte
Slide 6: What Did Literature Show?
WHAT DID LITERATURE SHOW? Reviewed Average length of trial 76 ~70 days published studies globally looking at with research spanning sheep / lambs supplemented with 2 days to 6 months probiotics Included grazing and intensive production systems; 100% growing lambs, grazing sheep and dairy ewes Resear
Slide 7: Lit Review Learnings
LIT REVIEW LEARNINGS Single strain vs multi-strain products Research focus: 46% vs 54% Animal health/health promotion as a primary or secondary metric 76% Growth performance 80% Most common microbes: Digestion / feed efficiency 40% Lactobacillus spp. 54% Rumen function / microbiome 47% Bacillus spp.
Slide 8: Lit Review Learnings: Key Points
LIT REVIEW LEARNINGS KEY POINTS • Research shows that probiotics overwhelmingly deliver benefit in all published literature • Probiotic efficacy depends on far more than simply increasing dose; and single strain • Strain selection, viability and delivery method are equally important determinants of
Slide 9: Australian Peer Reviewed Publication
AUSTRALIAN PEER REVIEWED PUBLICATION Nair et al., 2006: Freeze-dried Lactobacillus spp. Improved average daily liveweight gain and reduced methane intensity in growing lambs MERIL 2 Program; Hamilton SmartFarm, VIC (DEECA) 68hd completed trial following training to C Lock Smart feeders, 70d trial fo
Slide 10: What the Research Shows
WHAT THE RESEARCH SHOWS Strong Growth / Animal health Digestibility evidence: Performance outcomes Meat Feed Variable: quality intake Methane Early-life Immunology Emerging: reduction programming
Slide 11: Future Research / Opportunities
FUTURE RESEARCH / OPPOURTUNITIES Where research is heading • Commercially relevant research – scale & settings • Improved delivery technologies & seamless integration – water? Grazing systems? • Clear reporting on ROI • Drive investment in Australia
Slide 12: Reminder: What to Look For
REMINDER WHAT TO LOOK FOR 1. Quality standards ensuring viability (live bugs) at point of ingestion 2. Sheep/Lamb- relevant data – quality scientific research with proven strains 3. Support with delivery system - consistent dosing
