Diets with 0.0, 0.5,2.0, or 4.0% ground-aerIal parts of Senecio vernalis were fed to groups of 10 laying hens for 210 d. Plant alkaloid content was 0.14% with 8.57% in the basic form and 91.43% in the N-oxide form. Specific alkaloids were senecionin (66.65%), senecivernin (10.37%), seneciphylline (8.51%), integerrimine (8.44%), retrorsine (3.03%),(More)
Five groups of 20 female broiler chicks were fed different levels of dehulled Heliotropium dolosum seed (w/w%; 0.0, 1.0, 3.0, 5.0 or 10.0%) from 10 to 52 d of age. In all doses the seed caused decreases in daily feed intake, weight gain, and feed efficiency, and biochemical findings, severity of pathologic changes, and mortality rate increased in a(More)
Pyrrolizidine alkaloid intoxication was produced in adult, male rats by feeding different levels (0, 1, 3, 5 or 10%) of Heliotropium circinatum for 20 w. Combined GC-MS revealed 0.15% total alkaloid content in the plant material of which 12% and 88% were basic and N-oxide forms, respectively. The specific alkaloids identified were europine (67.33%),(More)
Experimental pyrrolizidine alkaloid intoxication was produced in inbred Swiss mice. Animals were fed diets containing 0, 1, 3, 5, or 10% Heliotropium dolosum seed for 24 w. The seeds contained 0.13% total alkaloid concentration composed of 4 specific components: lasiocarpine (78.79%), heliosupine (11.96%), echimidine (5.43%), and heliotrine (3.82%). Deaths(More)
