SCA NuTec is launching a new feeding programme to boost dairy cow fertility and milk productivity through consecutive feeding of two products each with a specific composition of omega-6 and omega-3 fatty acids.

There is growing evidence that Omega-3and 6 fatty acids fatty acids have beneficial effects on dairy cow health, particularly on the production of prostaglandin in the uterus, according to company ruminant nutritionist Norman Downey.

The two products; Strata-G Dry Period and Strata-G Lactation, can be used in total mixed rations or compound feeds.

Strata-G Dry Period is high in linoleic acid, an omega-6 fatty acid that stimulates prostaglandin production, the hormone that promotes contraction of the uterus, which is important around calving.

Strata-G Lactation is rich in omega-3 fatty acids sourced from fish oil. It would reduce prostaglandin production and helps embryo implantation by preventing embryonic loss.

Strata-G Dry Period is recommended for three weeks pre calving followed by Strata-G Lactation for the first four to six months of lactation.

The Strata-G Fertility Programme has been used successfully in trials. In one large-scale university-performed project with more than 500 cows, the group fed on the Strata-G feeds showed an improvement of 60-day pregnancy rates of 15 percent.

This same group also recorded milk yields of 1kg higher than the control group.

This level of improvement in fertility is estimated to improve margins by GBP 2,400 in a typical 100-cow herd.

Both feeds are recommended for feeding as part of total mixed rations or in compound feed.
