| Abstract: | An investigation on lipid composition of cow milk in shanghai has been successively made on the day 1,5,8(colostrum) and 45(mature milk) after parturition. The results were as follows; 1. The contents of total lipid, fatty acid, triglyceride, cholesterol and fat soluble vitamin A,E,D3 and (3 -carotene were highest on the 1st day, signinificantly different from the 45th d-ay(p<0.01). 2. From the first to 8th secreting day, concentration of long chain unsaturated fatty acids decreased slopingly, while vitamin did sharply, sometime even lower than that in 45th day. 3. The concentration of testoste-rone,progesterone and cortisol were not out of levels of mature milk, except estradiol. |
