Managing Butterfat at Grass

Butterfats typically reduce by 0.4% at turnout, with some herds experiencing 1% drops (i.e. 4.4% -> 3.4%). This often results in financial penalties or loss of income through not reaching constituent targets. Butterfat is made up of acetate and butyrate production, with glucose supplying the glycerol requirement. The rumen is made up predominantly of acetate/butyrate […]

Is Your Grass Too High?

Given the late season we have had, which has now been over-taken by dry weather, are you in the position of having grass covers that are too long? Are you struggling to get cows to graze grass down to the recommended 4 – 4.5cm residual when they leave a field? If so, you will not […]

Salvaging a Difficult Spring

The two graphs below depict how much grass was available for grazing when this 8,000 litre split block calved herd turned out to grass on the 16th April 2018, and where it was three weeks later on the 7th May. Any cover over 3,200kgs is very difficult to get grazed down to 1,700kgs. This herd […]

Managing Nitrogen Applications in Multi-Cut Grass Systems

The three key principles of good silage making are dry matter, sugar and reducing buffering capacity. Fig1. Changes in PH of crops of low and high buffering capacity in first 10days of ensilement (Wilkinson,2005). “The aim of ensilement is to achieve a stable forage between 3.8-4 PH” Multicut silages are an excellent way to provide […]
