Scanning Update February 2018

Scanning is well underway now. Of the 108 spring-calving herds scanned so far, the average 6-week in-calf rate is similar when compared to last years results for the same herds at this time. 
As usual there has been a huge range in 6 week incalf rate across the practice – 41% to 84%. A good number of farms are achieving the industry target of 78%. 
The average 6 week incalf rate last year had dropped in our herds to 68%, which was the first drop we had seen in about 3-4 years, and was consistent with the National Dairy Statistics, which indicated a national drop in 6 week incalf rate last season. 
There is hope for this season’s results at this early stage, with improvements in 6 week incalf rates of about 1% in both the Gordonton and Te Aroha areas. 
It is too early to give an average empty rate as yet, as most herds the final scan for empty rate is only being completed as this newsletter is being prepared. 
The results vary from farm to farm, and there are farms this season who have made big gains in performance, and some who have dropped back. The reasons for the changes in performance are many and will be individual to every farm. Good herd reproductive performance requires on-going attention. It requires focus and hard work, and we understand that it can be hard to stay motivated. Progressing to a higher incalf rate will require extra effort. Doing the same as you’ve always done won’t improve the situation. 
If you are not reaching your herd reproductive targets, consider talking with one of our trained In-Calf advisors.
