The individual allocation of concentrates in lactating dairy cows is usually based on each cow’s milk production and lactation stage only, without considering other requirements. Thanks to the development of on-farm technologies, a more precise estimate of cow’s needs is conceivable. The objective of this study was to demonstrate the feasibility of precision feeding as described in the Harpagon project and compare it with two standard feeding methods. 69 Holstein dairy cows were fed ad libitum with a unique balanced diet distributed in individual weighing bins and supplemented individually via an electronic feeder with 5 kg/d/cow (P5kg) of concentrate for 3.5 weeks and 1 kg/d/cow (P1kg) for the following 3.5 weeks. A response profile based on milk production and feed intake during the feed restriction period (P5kg-P1kg) was used to design the treatments. Cows were divided into 3 batches for a 12.5-week period: 23 cows were fed concentrates individually according to their response profile (Harpagon), while 23 others were fed according solely to their milk production (TemoinRSC). The 23 remaining cows were fed a total mixed ration (TemoinRC). On a batch scale, the animals were all fed the same average amount of concentrate, and batches did not differ in production or intake levels. However, some profiles maintained similar production with less concentrate and could be worth identifying to adapt the quantities of concentrates distributed. To validate those results, the next step is to investigate the profile robustness throughout the entire productive life of a dairy cow.
