Omega 3/6 product benefits dairy fertility
SCA NuTec will launch a new feeding programme to boost dairy cow fertility.
This programme consists of consecutive feeding two products each with a specific
composition of omega-6 and omega-3 fatty acids.
"Omega-3 and 6 fatty acids are attracting a lot of
attention in human nutrition and there is growing evidence that these fatty
acids also have beneficial effects on dairy cow health, particularly on the
production of prostaglandin in the uterus," says company ruminant nutritionist
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. Its role is to reduce
prostaglandin production. It plays an important part in embryo implantation by
preventing embryonic loss.Trials
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%. 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 £2400 in a
typical 100-cow herd.
Both feeds are recommended for feeding as part of
total mixed rations - available in 25kg bags - or in compound feed at a rate of
115g/head/day. Strata-G Dry Period is recommended for three weeks pre calving
followed by Strata-G Lactation for the first four to six months of
