Achieve better in-calf performance this spring

Achieve better in-calf performance this spring

27 July 2017

Last spring, weather conditions throughout most of New Zealand turned nasty just as cows started mating.

Not surprisingly, autumn's pregnancy test results have indicated the impact last year’s wet spring may have as calving unfolds. Fewer cows in-calf in the first six weeks and higher empty rates can mean losses and wastage in some of our herds. While we can’t do anything about last year’s mating results, we can plan for a better outcome this year.

Attention to detail well before the planned start of mating is essential to offset negative influences such as a lack of iodine in pasture due to the continued high water-table, or low trace element status in cows. Taking control of metabolic problems post-calving and preparing the cow for insemination will be on the action list of proactive farmers.

To help farmers achieve more sustainable fertility outcomes Bell-Booth has formulated Nutrimol 4n1, a product to address poor heat strength, heat length and short and long returns.

The unique 130-day 4n1 mating programme has been used by hundreds of dairy farmers who have seen good results.

The Nutrimol 4n1 formulation targets the four main issues many farmers experience through the reproduction process. They are:


4n1 contains iodine which is essential for thyroid function, foetal survival and overall healthy development. Adding 4n1 to the diet on a daily basis assists cows to cycle, which in turn supports heat-detection and the readiness of the cow to ‘come-up’ and maintain a strong heat.


4n1 contains folic acid (vitamin B9). Human studies show the use of B9 can reduce the risk of neural tube defects involved in the formation of the central nervous system. Furthermore, adequate B9 levels are important in supporting rapidly-growing foetal tissue during the first three months of pregnancy.


Nutrimol 4n1 contains multi-vitamins. Good levels of vitamin A reduce the reproductive tract’s susceptibility to infection. Vitamin D stimulates the absorption of phosphorus and calcium, both of which are essential in bone formation especially in rapidly-growing animals. Vitamin E functions primarily as an antioxidant.


The addition of a prebiotic to 4n1 provides a food source for the rumen bugs, assisting the cow’s feed-conversion process.

For best results begin dosing Nutrimol 4n1 30 days prior to the planned start of mating to encourage strong heats. Farmers say their cows really get cycling within a few days of use. The 4n1 program continues until 60 days after the end of mating.
