Dairygold Grass Extender Options

Dairygold Grass Extender Options

by Colman Purcell, Nutritionist, Lombardstown Mill

 

Dairygold has introduced a suite of grass/fodder extender options for 2018 based on the most suitable and best value raw materials that are available. These extenders are available as individual straights or in coarse and cube form. These raw materials were chosen as they are the best options from an; availability, nutrient density, mineral balance and price per unit energy stand point

 

Grass Extender coarse/cube:

Our grass extender is based on gluten and soya hulls. It is a 15.5% crude protein mix. This higher protein level is required to replace summer grass, which generally has a protein level of c.16-20%. It has a UFL of c.1.05 on a dry matter basis. It is non-mineralised but will carried a phosphorus level that exceeds the cows requirement. You will need to feed cal mag and trace elements through your parlour concentrate or through a mineral mix.

 

Fodder Extender coarse/cube:

Our fodder extender is based on soya hulls and palm kernel. Due to the non-availability of palm kernel this product is not available until early August. Its is a 12% crude protein mix with a UFL of c. 1 on a dry matter basis. It is non-mineralised but will carried a phosphorus level that meets the cows requirement. You will need to feed cal mag and trace elements through your parlour concentrate or through a mineral mix.
