The Kaliber Young Livestock Plan for a younger calving age

- The pre-puberty phase in calf raising (the age from five to eight months) is crucial for achieving a younger calving age. In this article we pay attention to the pre-puberty phase.

From research and practical experience we know that young livestock can grow very quickly in the pre-puberty phase. We have measured growth of more than 1,000 grams a day. Naturally, rapid growth is very nice for quickly reaching the insemination weight, however, it is important to distinguish the type of growth. Animals can grow through becoming fat or grow through the development of the muscles and the carcass. The latter, growth of the muscles and the carcass, is what we want to achieve with the Kaliber Young Livestock Plan.

Proportion of crude protein to NEL

The objective of the pre-puberty phase is clear: as high as possible daily growth of carcass and muscles without fatty degeneration. We achieve this mainly through the correct proportion of crude protein to NEL. The NEL should amount to 950 and the crude protein 17 per cent. A second norm in this period is a minimum ration of 2 to 2.5 kg Euro Junior. Euro Junior is compiled based on the needs of the calf and supplements the protein and the energy. This provides a good basis for a fast daily growth in the pre-puberty phase.

In the pre-puberty phase young livestock can grow very quickly, up to more than one kilogram a day

Slow growth

From practical experience we know that animals in pre-puberty often grow too slowly and as a result we miss the objective. Usually this is due to the compilation of the ration. The wrong proportion of crude protein and NEL with a low percentage of crude protein often results in fatty, flat animals that lag behind in height and total development. A too low NEL level combined with a good crude protein percentage often results in animals that lag behind in terms of total development, often in an acute condition and with a poor hair coat.

Silage is decisive

Silage determines the quantity of maize that we can add to the ration. This quantity is often between 15 and 35 per cent. Ensure a good transition from hay in the start phase to silage and maize in the pre-puberty phase. A transitional resting place where both rations are fed works well in practice.
