Description
For 420 days, 103 Italian Friesian cows were fed on diets containing maize silage (7.5 kg DM) and hay (3.5 kg DM) or only hay (9.7 kg DM) (group S). Maize silage significantly increased blood glucose and ceruloplasmin and decreased calcium, albumin and packed cell volume. Many of these variations, which coincided with a slightly higher incidence of digestive illness and lameness, were in periods when diets high in starch and sugars (>25% DM) were given. Silage with DM <28% lowered DM intake and increased blood sodium and chloride. In conclusion, when good maize silage was used and the diet was balanced, no negative effects on health, metabolic condition or fertility were observed
