Limiting unproductivity!
GAEC CHARRETIER - Duerne (69)
Mathias and Jean-Pierre CHARRETIER farm 90 hectares in DUERNE (69), a commune at an altitude of 850 meters, in the heart of the Monts du Lyonnais. They produce 700,000 liters of milk and sell 35 crossbred heifers and steers a year. 30 Ha of arable land are planted with corn, barley and temporary grassland, with the remainder in rotational grazing for dairy heifers. The furthest plots are reserved for butchering animals.
65 VL at 11,300 liters for 32 TP and 39.8 TB, the young herd of GAEC CHARRETIER is nothing short of high-performance. These performances attract a regular clientele of 15 large producers in 3rd or 4th lactation every year. The sale of these 15 VL is really profitable thanks to the reduction in charges, early calving (average of 25 months) and very good depreciation, with 3 liters per day of life above the departmental average!
Heifer breeding is strategic and nothing is left to chance. Meadow supplementation adapted to grass quality and rotational grazing ensure strong growth and early AI. Further lowering the average age of first inseminations could be a way forward for Mathias, who needs to anticipate his father’s retirement.

With already optimized management, genetics and the PRECOCITE index can be a lever to work on. In addition to saving on dehorning work, the 15 PAYET P (+2.9 PR) daughters in the herd will be inseminated around 22 days earlier than their dams, thanks to the genetic effect alone.
After PAYET P, RHUMRAISIN, POLFOUX P, PLATON and SHERLOCK, the sires of the 2023/2024 campaign will be SOLIXOR, SITOLO, SORBON RF and SUMMUM.
Mathias and Jean-Pierre particularly appreciate cows of limited size for their mobility and feed efficiency. “These cows make repeat customers because of their adaptability once they arrive home.

The perfect cow for me can be summed up in 4 words: Members, Rate, Milk and Logette!
