Effet de la conduite du pâturage sur la production laitière et le comportement alimentaire des chèvres

Abstract : In a context of price volatility and low feed self-sufficiency of goat producers, grazing may play a more important role in the goat feeding systems. Two trials of three weeks were carried out at the experimental farm of Méjusseaume (Le Rheu, UMR PEGASE) with 36 Alpine goats in mid lactation (100 days). The first trial compares 3 grazing access times (TA: 4, 6 and 8 h / day) with a individual intake of 400 g of dehydrated fodder after the evening milking, 306 g of concentrate at each milking, and a pasture allowance of 2.0 kg DM / d / goat (> 4 cm). The second compares 3 pasture allowances (QO: 1.6, 2.3 and 3 kg DM / d / goat > 4 cm), with 306 g of concentrate at each milking and 13 h / d of grazing. In both trials, milk production response (PL) is curvilinear, with identical PL between medium and high levels and only lower PL for the low level (- 300 g of milk for the low TA and - 500 g of milk for the low QO). Milk fat and protein contents only slightly varied with treatments. Goats maintain an intense grazing activity in both trials for several hours, regardless of the access time to pasture. Finally, the goats had the same type of response that cows to variations in grazing management, but they seem more sensitive, with a specific feeding behavior.
