Polyunsaturated fatty acids in the milk fat of cows

, : Polyunsaturated fatty acids in the milk fat of cows. Vest. sel'-khoz. Nauki, Mosk, 10: 6, 79-84

The use of spectrophotometric analysis to determine the content of polyunsaturated fatty acids in butter-fat of Black Pied, Jersey and Black Pied x Jersey cows gave the following average results (in mg. %) during the winter indoor housing and summer grazing periods respectively: conjugated diene, 592.4 and 1, 102.4; conjugated triene, 21.2 and 37.0; conjugated tetraene, 2.5 and 5.0; unconjugated diene, 2, 369.6 and 1, 835.8; unconjugated triene, 310.5 and 676.7; and unconjugated tetraene, 263.8 and 297.0. During the summer grazing period there was an average increase of 10% in the total content of polyunsaturated acids, that of conjugated acids rising by 2-2.7 times, while the levels of unconjugated acids varied, falling for diene, doubling for triene and remaining almost unchanged for tetraene acids. The butterfat of Jersey and cross-bred cows contained 13-17% less total polyunsaturated fatty acids and nearly twice as much conjugated triene acids as that of Black Pied cows.

Fusicoccin, the toxin from Fusicoccum amygdali, at 1-10 ppm. stimulated shoot growth of rice seedlings. Shoot growth was inhibited by concentrations of >70 ppm. Ophiobolins A and B had a similar effect to fusicoccin but were less active.
