The Co-Synch program is generally administered with a progesterone insert such as a DIB-V or DIB-h.
NZ research shows that the combined progesterone insert and Co-Synch programs have the best chance of getting heifers to ovulate and conceive promptly, with resultant higher pregnancy rates.
Use Co-Synch programs in tandem with a progesterone insert to synchronise cycling heifers or cows, so that all animals can be inseminated on the same day with good conception rates to AI.
Another option is using Co-Synch program without a progesterone device (this program is also known as ovsynch or GPG) with heifers. This program is cheaper, but as pregnancy outcomes are lower it makes better economic sense to add a progesterone insert to the program each time. This is because substantially more milk is produced from the higher proportion of cows in-calf earlier with Co-Synch program. The other benefits includes tighter calving spread, less wastage as 3 year old cows and faster genetic gain.
Gonasyn and Cyclase are New Zealand restricted vet medicines. Please contact your veterinarian for advice on the best program for your herd.
