Successful Lambing starts at tupping

Lambing might seem a long way off, but key steps running up to and during tupping can lead to a less stressful and more productive spring. A healthy lambing percentage sets the profitability for the season so optimising management now and as the rams go in is the crucial foundation for a successful year.

Flushing ewes is commonly practiced to improve ovulation rates, but the benefit is only seen if the ewe is in a suitable body condition score (BCS) to benefit from the rising plane of nutrition. Optimal BCS will depend on the breed and farm situation but if it’s below 2 or over 4 then it will be unlikely to have any effect. Seeing as it can take 2 months on good grass to raise BCS by 1, early planning and action is key.

Equally important at this time is to ensure trace element and vitamin levels are correct. For example, selenium deficiency can result in increases embryo loss. Nettex Sheep Conditioning Drench is formulated for use in ewes to ensure they are in the best condition possible at this time of year.

It’s important not to forget the rams, Vitamin E, Zinc and Selenium, all contained in Nettex Sheep Conditioning Drench, are important for improving sperm production and survival.

Practical management at tupping also has a beneficial impact on both the profitability and practicalities at lambing. Effective and reliable marking lets you know which ewes have been tupped, by which ram and when! Barren ewes can be identified which saves winter feed costs, and ewes can be grouped by expected due dates. Tight grouping at lambing time can save labour and stress which leads to improved lamb survival at lower costs. Using a range of colour crayons, changed regularly also allows spotting of rams that are perhaps underperforming.

To maximise the benefits of marking you need a good well-fitting harness and a range of clear colours. You also need to be confident that the crayons will stay in pace and last for a required time.
