The long-term performance of dairy cows is determined by the first few months of their life as a heifer. This phase is highly critical. According to Soberon & al., 2012, lifetime performances are influenced by early life development which can be manipulated via nutrition. This manipulation should start immediately after birth and continue at least for 5 weeks.
The 0 – 6 months period represents less than 10% of a dairy cow’s life but accounts for about 25% in terms of weight growth and 54% of height growth.
In the past decades, heifers and dry cows had very little consideration as they are unproductive animals, not generating any cash for farmers. This time is now behind them and the new approach is to adapt nutrition of these animals to the farm objectives.
Full nutrition programs including nutrition of dry cow for a good colostrum quality (and consequently an improved heifer’s immunity), milk replacers and starter feed dedicated to heifers are now commonly used.
There are 3 mains strategies for heifers:
Early weaning strategy
(6 weeks weaning)
(8 weeks weaning)
(> 950 g/day ADG)
Farmers can adapt their strategy according to different parameters of their farm: labor force, building capacities, grouped calving or not, feeding equipment… The chosen strategy for heifers nutrition does not matter, all of them aim to a first calving at 24 months which remains far from the current average age at calving in most of world’s countries
In all cases, investing in early-life nutrition permits to boost future economical performances of farms.
