Crotalaria spectabilis Poisoning in Swine

Journal of the American Veterinary Medical Association, 1974
SUMMARY When a ration containing corn contaminated by Crotalaria spectabilis seeds was fed to a herd of swine, 76 of 150 pigs died. Deaths first occurred 6 weeks after initial consumption of the ration and 3 weeks after the loss of black hair, the 1st clinical sign observed.

The Toxicity of Crotalaria Spectabilis Seeds for Quail

The Journal of Wildlife Management, 1941
Crotalaria as a cover crop is gaining attention in our country's conservation program. This genus of the legume or pulse family consists of more than 600 species. Of this number at least six are known to be very toxic to cattle, sheep, and horses, namely, C. sagittalis, C. juncea, C. burkeana, C. dura, C. globifera, and C. spectabilis.

The Alkaloids of Crotalaria spectabilis Roth

Australian Journal of Chemistry, 1957
Monocrotaline and a new alkaloid, spectabiline, are isolated from Crotalaria spectabilis Roth. in nearly equal amounts. Spectabiline is shown to be an O-acetylmonocrotaline and has been prepared by acetylation of monocrotaline.

Crotalaria spectabilis Toxicity Studies in Turkeys

Avian Diseases, 1963
A number of reports have concerned the toxicity of Crotalaria spectabilis in various animal species. The toxic factor has been isolated, its molecular configuration established, and has been identified as monocrotaline (11). This alkaloid or the seed of C. spectabilis will produce pulmonary and intrahepatic hemorrhage and liver necrosis in rats (10,12),

Clinical Signs and Pathologic Changes in Crotalaria spectabilis-lntoxicated Rats

American Journal of Veterinary Research, 1970
SUMMARY Sprague-Dawley rats were fed a ration containing Crotalaria spectabilis seed for 8 months. The concentration of this seed in the ration was varied from 0.02 to 0.08%. Initially, the lowest concentration was used; changes were made by a 0.02% increment every 45 days for the first 6 months, and the highest concentration (0.08%) was maintained ...

Crotalaria spectabilis toxicity in swine: Characterization of the renal glomerular lesion

Journal of Comparative Pathology, 1975
Abstract Eighteen feeder pigs each received a cumulative dose of 84 g. of ground Crotalaria spectabilis seeds in 43 days. Varying degrees of lack of thrift were seen in all pigs. During the experiment 2 pigs died from crotalaria poisoning. The survivors were necropsied in 2 groups, 70 and 90 days after the experiment began.

Effect of Environment on the Translocation and Toxicity of Acifluorfen to Showy Crotalaria (Crotalaria spectabilis)

Weed Science, 1981
Toxicity of non-radiolabeled and absorption and translocation of14C-activity of applied14C-acifluorfen {5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid} in showy crotalaria (Crotalaria spectabilisRoth) were evaluated in the growth chamber at air temperatures of 18, 27, or 35 C and 40 or 100% relative humidity (RH). Four days after treatment,

Effects of Shading and Temperature on Showy Crotalaria (Crotalaria spectabilis)

Weed Science, 1982
Showy crotalaria (Crotalaria spectabilisRoth) was grown in a controlled-environment greenhouse with a day/night temperature of 32/26C at full sunlight and under 40, 60, or 90% shade. Shading significantly reduced height, dry-matter accumulation, leaf production, leaf-area expansion, axillary-branch development, reproductive development, and the ...

Modelling of the supercritical fluid extraction of monocrotaline from Crotalaria Spectabilis

The Journal of Supercritical Fluids, 1989
Abstract In our extractions of Crotalaria spectabilis with supercritical carbon dioxide and carbon dioxide-ethanol mixtures, we observed history-dependent extraction, possible monocrotaline-lipid fluid phase repulsive interactions and cosolvent retention-release phenomena.

Seed Coat Impermeability and Germination of Showy Crotalaria (Crotalaria spectabilis) Seeds

Weed Science, 1979
Showy crotalaria (Crotalaria spectabilisRoth) seed dormancy was due to seed coat impermeability to water. The seed coats became impermeable during later stages of maturation on the plant. When incubated immediately after harvest, 9% of the mature, black seeds (11% water content) imbibed water and germinated.
