Trend in ash and mineral element content of milk from Haflinger nursing mares throughout six lactation months.

Published: 2004-10-18

Brief content of the article
Effects of lactation duration were investigated on contents of ash and minerals in milk from 10 Haflinger nursing mares. The mares (400-540 kg live wt; 4-12 parities) were reared in a stud in Brescia province, northern Italy. The researchers took 80 milk samples by hand milking of 1 gland on days 4, 20, 40, 60, 80, 120, 150 and 180 postpartum. The authors observed that from days 4-180 postpartum, ash contents decreased significantly from 0.58 to 0.28 g/100 g of milk. In the same period, contents of several mineral elements also decreased significantly (Ca; P ; Mg; K ; Na and Cl-). Decreases in ash and mineral contents followed a curvilinear pattern relative to days of lactation that was well described by cubic equations.
