WORKING TOGETHER FOR REPRODUCTIVE SUCCESS
CIDR is the trusted, market leading non-cycler treatment, developed and proven in New Zealand.
NON-CYCLING COW MANAGEMENT
Typically 20% of dairy cows in New Zealand are not detected in oestrous by the planned start of mating. These cows negatively impact the herds calving spread, which is an indicator of calving spread. A compact calving spread means more days in milk and greater flexibility in the following mating.
Non-cycling cow management plays an important role in herd fertility.
Early blanket treatment of non-cyclers maximises return on investment
GET PREPARED FOR MATING
Planning for mating is critical to achieve your goals for the year. make sure you sit down with you vet well in advance and set targets for you mating performance this year.
As a rule, you should also:
- Perform regular body condition scoring of calving and calved cows and endeavour to decrease as much as possible weight loss between calving and mating. Target less than 1 BCS loss for every cow.
- Talk to your vet about the best way to manage and identify cows with endometritis early. High risk cows for endometritis are also at high risk of becoming non-cyclers.
- Tail paint all cows 35 days before planned start of mating (PSM) Observe and record premating heats Assess how many cows are non-cycling at 10 days before PSM, and talk to your vet about treatment. CIDR treating non-cycling cows at 10 days before PSM will give you the best return on investment, and get your cows in calf earlier for next year.
- Assess late calving cows early. Late calvers often have not been calved long enough to be treated with CIDRs at 10 days before PSM, however they have a high risk of not getting back in calf for next year. Talk to your vet about the best strategy for managing these cows.
KEY BENEFITS
Using CIDR to treat non-cyclers gives you:
- More days in milk
- Helps to compact calving spread
- More AB calves
All of these factors combine to improve your herd’s productivity and increase genetic gain.
Maximum return on investment
Your vet can discuss the return on investment of various non-cycler treatments with current payout figures.The best return on investment is achieved by treating all non-cyclers early (before the planned start of mating) to maximise extra days in milk.

Cows in calf earlier
In 2008, a large scale Waikato study examined the impact of early treatment on non-cycling cows with CIDR Cattle Insert. The CIDR programme advanced the conception date of the CIDR group by 10-16 days compared to the No Treatment group.
Talk to your vet to see if CIDR Cattle Inserts are right for your herd.
