Breeding Season: A Practical Plan from Ram In to Lambing

The breeding season is the day next year's revenue is decided. Every week the ram goes in late is a week lambing is late, which means smaller lambs at selling time. And yet many breeders run this season from memory — "we put the ram in around Shawwal" — and are then surprised by births scattered across three months, which makes feeding and vaccination almost impossible to manage.

Here is a practical season plan that works for 30 head or 3,000.

One month out: preparation

Score the ewes' body condition. A female that is too thin or too fat conceives less often. Use the 1-to-5 body condition score and aim for 3 to 3.5 at mating. Thin females need a nutritional lift (flushing) 3–4 weeks before the season.

Check the rams. One infertile ram can waste the entire season. Check legs, testicles and weight, and give him time to acclimatise on good feed beforehand — a ram working a full month loses a lot of condition.

Finish vaccinations and parasite control. Avoid doing either on a female in early pregnancy if you can.

Ram-to-ewe ratio

The common rule is one mature ram per 25–35 ewes under barn conditions, and one young ram per 15–20. For an intensive short season (six weeks, say), reduce the number. Use more than one ram in a large group so the season does not stop if one falls sick.

Splitting the season into cycles

The oestrus cycle in sheep repeats roughly every 17 days, so:

• A 34-day season = two cycles: every female gets two chances. Very concentrated lambing.
• A 51-day season = three cycles: better coverage, lambing still manageable.
• Longer than that = scattered births that are hard to manage.

Write down the date the ram goes in and the date he comes out. Those two dates alone give you the expected lambing window.

Calculating the due date

Gestation in sheep and goats is around 150 days (145–155 depending on breed and litter size). The working rule: mating date plus about five months. Camels are entirely different — roughly 13 months.

30–45 days after mating, pregnancy can be confirmed by ultrasound. This scan is the most valuable economic decision of the season: it tells you which females are pregnant (feed for pregnancy), which are empty (re-breed or cull instead of feeding them for five months with no return), and which are carrying twins (higher nutrition in the last two months).

The numbers that judge the season

At the end of every season, calculate three figures. Without them you cannot tell whether you are improving:

Compare them across seasons, across rams, and across ewe groups. You will often find that one ram or one group of dams explains the whole difference — and that is a culling decision that saves a full year of cost.

The final weeks before lambing

Seventy per cent of foetal growth happens in the last two months. The dam needs higher nutrition here, especially carrying twins. This is also when the clostridial booster is due (4–6 weeks before lambing), so the protection reaches the newborn through colostrum.

Prepare the lambing area: clean, dry, out of draughts, with fresh bedding. And record every birth as it happens — dam number, number of lambs, sex, weight, and any difficulty. Those lines are what give you, two years from now, a clear picture of your best dams.

How Throf simplifies the season

The breeding hub shows you on one screen how many females are pregnant today, how many are overdue against their expected date, and how many are empty. It calculates conception and twinning rates automatically, ranks rams and dams by performance, and sends an alert before the pregnancy check and the expected lambing date — so you never have to remember a date.

The short version

A good season = a fit ram + ewes in the right condition + a short season with fixed dates + a pregnancy scan on time + concentrated nutrition in the last two months + a written record. Each element is simple on its own; the power is in doing all of them, every year.
