The main average results were: MY= 288.2 kg, LL = 254 d with 3.5% fat, 3.4% protein and 4.6% lactose.Forage/concentrate ratio significantly affected MY and fat being highest in goats receiving a ratio of 65/35. Milk yield in goats fed with a ratio of 35/65 was richer in fat (3.6%). The protein and lactose content was not affected by the different ratios. The effect of diet on fat content was small but significant. Parity influenced all the factors considered, in particular goats in ≥4th parity, had longer LL (257 d) and consequently a higher milk yield (302.1 kg). Goats kidding twins yielded more milk and had longer lactation (P < 0.001).
