Achieve full feed potential from wholecrop silage Yields of wholecrop silage across Northern Europe are expected to dip by up to 20% this year. Yields of wholecrop silage across Northern Europe are expected to dip by up to 20% this year. Wholecrop, which incorporates the stem and grain and is fermented as silage, offers an alternative or additional feed to grass or maize silage, particularly in situations where it may be difficult to achieve ideal spring-sowing conditions, says Catherine Sharpin of Lallemand Animal Nutrition/Nutritech. Farmers also see the benefits of using an additive in systems where wholecrop silage is fed out in advance. “It has improved our wholecrop silage and that means higher nutritional value and improved palatability for our livestock.’’
