Studies in relation to feeding weanlings over the winter period have concluded that each one percentage unit decline in DMD of grass silage requires an additional 0.3kg concentrate to sustain performance. This emphasizes the importance of silage quality and what role it has to play in relation to the weight gain of your animals on farm. For instance, a weanling fed 65% DMD silage will require 2kg concentrates (high energy feed i.e. UFL greater than 0.93 fresh weight) in order to grow at a rate of 0.6kg a day over the winter period (Shown in the table below). Therefore, in order to know your feeding value of your silage and growth rates, it supports it’s of fundamental importance to get it tested and balanced accordingly in order to achieve the desired weight gains on your farm.

In relation to protein requirements. Generally a 16% crude protein ration will be adequate for weanlings in relation to their muscle and skeletal development. However, where silage protein results are low i.e. less than 10% perhaps one might need to look at a ration containing greater than 16% crude protein.

*It is important to note while feeding will have the major effect on weight gain. Environmental factors will contribute to it also., if pen space, trough space and parasite control are not correct performance will be compromised.
