Tupping Time: Getting Rams and Ewes Ready for a Successful Breeding Season

As the days shorten and the mornings turn crisp, UK sheep farmers know tupping time is just around the corner. Whether you’re running a pedigree flock or managing commercial ewes, preparation is everything. A well-planned breeding season sets the tone for lambing success, and it all starts now.

Here’s your checklist for getting rams and ewes in top shape before they meet.

Body Condition Scoring (BCS): The Foundation of Fertility

Getting BCS right is one of the most powerful tools in your management kit.

Ewes:

• Target BCS: 3.0–3.5 for lowland breeds; 2.5–3.0 for hill breeds
• Why it matters: Ewes that are too thin may struggle to conceive or carry twins. Overfat ewes are prone to metabolic issues and poor ovulation.
• Action: Assess 6–8 weeks before tupping. Adjust nutrition accordingly, either by supplementing or separating into groups for tailored feeding.

Rams:

• Target BCS: 3.5–4.0
• Why it matters: Rams lose weight rapidly during tupping. Starting in good condition helps maintain libido and stamina.
• Action: Increase energy intake if needed, but avoid overfeeding, fat rams can suffer from reduced fertility.

Tip: Use hands, not eyes. Feel over the loin and ribs to get a true sense of condition.

Health Checks: Prevention Beats Cure

A healthy flock is a fertile flock. Now’s the time to get proactive.

Rams:

• Feet: Trim and treat any signs of lameness. A lame ram is a useless ram.
• Teeth & Jaw: Check for dental issues that could affect feeding.
• Testicles: Palpate for firmness, symmetry, and absence of lumps. Any abnormalities should be checked by a vet.
• Breeding Soundness Exam: Consider a vet check for high-value or older rams.

Ewes:

• Vaccinations: Ensure boosters are up to date, especially for enzootic abortion and toxoplasmosis.
• Worming & Fluke: Conduct faecal egg counts and treat if necessary.
• Trace Elements: Consider boluses or drenches if you’re in a deficient area (e.g., selenium, cobalt, iodine).

Tip: Don’t forget quarantine protocols for any new stock, biosecurity is your first line of defence.

Breeding Prep: Timing, Ratios & Teasers

Timing:

• Cycle Length: Ewes cycle every 17 days. Plan for at least two cycles to maximise conception rates.
• Flushing: Increasing nutrition 2–3 weeks before tupping can boost ovulation rates, especially in lean ewes.

Ratios:

• Ram to Ewe: 1:40 is standard for mature, fit rams. Younger or less experienced rams may need lighter loads.
• Synchronisation: If using teasers or sponges, plan carefully and consult your vet or advisor.

Teasers:

• Use of Vasectomised Rams: Introducing teasers 14 days before the fertile rams can help synchronise oestrus and tighten lambing.

Marking harnesses are a must, rotate colours every 17 days to track coverage and spot any fertility issues.

Tupping isn’t just about putting rams in with ewes, it’s about setting the stage for a productive, stress-free lambing season. With drought conditions still affecting forage availability in parts of the UK, nutritional planning is more critical than ever. Don’t leave it to chance.

Check, score, feed, and monitor. Your future lamb crop depends on it!
