One of the most eﬀective ways to prevent grass tetany in dairy cows is magnesium supplementation during the risk period. Choosing the supplementation source is quite challenging in practice, magnesium oxide being commonly used to prevent Mg deﬁciency, but the solubility and therefore the bioavailability varies greatly in practice (1).
There are no silver bullets in farming. If there was a management practice that resembled one, then relentless attention to detail would have to be the closest option. When it comes to dairy farming and in particular transition cows than the 4 F’s are often cited as the nearest thing (Forage, Feet, Feed, Facilities) although choline nutrition could be considered a close second.
Low magnesium status and sub-optimal rumen pH can be no stranger at spring turn out. At Wynnstay we believe the dual functionality of pHix-up, can be harnessed to both safeguard rumen health and enhance magnesium supply at grass.
Grazing in the spring often leads to a loss of production in dairy cows. Grass tetany may be the cause. The disease causes a decrease in appetite, milk production and milk fat content. The cause: a lack of magnesium, often associated with a drop in ruminal pH.
Home grown feed is the cheapest feed available to farmers. Hardly a revelation but as farm inputs continue to rise the drive for milk from forage becomes a more crucial metric. Every additional litre from forage could be worth up to 20p per cow per day, or £600 per month for every 100 cows in the herd.
Dry matter – Is grass providing enough dry matter intake to support the energy requirement for milk production and getting cows back in calf?
Protein – Grass is high in rapidly degradable protein; this needs to be utilised by the rumen microbes in order for them to produce microbial protein. Poorly utilised protein can have a negative impact on fertility and limit milk yield.
Rapidly fermentable carbohydrates – Early season grass is high in sugar (and digestible fibre), this can be an issue for rumen health. A consequence of this can be milk fat depression and a reduction in milk value. It is important to understand the nutrient content of grass. Fresh grass analysis throughout the grazing period will provide useful information about the points above.
Sustainability is a key part of our business, with our mission being to help farmers feed the UK in a more sustainable way. As a business, we are working towards becoming carbon net zero and aim to support our customers with products and services that help drive sustainability and efficiencies. Through our feed division we have made the following commitments:
From the 1st May 2022 three new Climate compounds will be available with the inclusion of Rumitech®, a methane reducing additive.
Congratulations to the Albutt Family of Winchcome who recently won our January prize draw in conjunction with QLF. The family chose the prize of an IBC of L-CBF BOOST as they already use QLF Allstock Lite molasses.
Dairy farmer Jonathan Evans wanted to improve milk quality from his 220 cows to improve milk price and he is now reaping the benefits of close teamwork between his Wynnstay Agronomist and Nutritionist.
