The effects of changes in the body-weight of cows on the composition of their milk.
Ninety-six cows (48 Ayrshires and 48 Friesians) were weighed at seven day intervals. Forty-six cows gained weight and showed significant average increases in milk yield and solids-not-fat (SNF) percentage and non-significant rises in protein percentage and freezing point. The fat percentage was significantly lowered. The other 50 cows lost weight and a significant drop in SNF percentage was recorded. The other parameters showed non-significant falls.
