Experimental 3-nitro-4-hydroxyphenylarsonic acid toxicosis in pigs.
Five times the recommended dose of 3-nitro-4-hydroxyphenylarsonic acid (187.5 mg kg-1) induces a pathognomonic clinical syndrome in pigs. The main clinical features are not continually present but are inducible only by exercise. From day 11 on the experimental diet a nervous syndrome was inducible. This manifested as muscle tremors and clonic convulsive episodes. Paraparesis developed by day 22...
متن کاملArsenic in tissues of sheep and milk of dairy cows fed arsanilic acid and 3-nitro-4-hydroxyphenylarsonic acid.
Arsenic from two sources--arsanilic acid and 3-nitro-4-hydroxyphenylarsonic acid (3-nitro)--was fed to mature wethers and lactating dairy cows, and the uptake and depletion of arsenic in tissues and milk were determined. In experiments with sheep, arsenic concentration in liver, kidney and blood increased as the level of arsenic from arsanilic acid and 3-nitro was increased in feed. Muscle arse...
متن کاملNarasin toxicosis in finishing pigs
This case report documents a clinical case of narasin toxicosis in a group of 19-week-old finisher pigs caused by accidental overdose of narasin in the feed at concentrations varying from 139 ppm (139 g per tonne) to 645 ppm (645 g per tonne). Affected pigs exhibited anorexia, pain (vocalization), skeletal muscle weakness, ataxia, recumbency, and dyspnea. Pathological lesions in the affected pi...
متن کامل3-Nitro-4-(propylamino)benzonitrile
In the title compound, C(10)H(11)N(3)O(2), the nitro group is essentially coplanar with the aromatic ring [dihedral angle = 1.3 (3)°] and forms an intra-molecular amine-nitro N-H⋯O hydrogen bond. In the crystal, weak inter-molecular aromatic C-H⋯O(nitro) hydrogen bonds link the mol-ecules. Weak aromatic ring π-π inter-actions [minimum ring centroid separation = 3.7744 (13) Å] are also present.
متن کاملTiamulin and narasin toxicosis in nursery pigs
This case report describes a clinical case of tiamulin and narasin toxicosis in a group of nursery pigs, caused by the inadvertent introduction of narasin at 83.1 g per tonne into a ration containing tiamulin at 31.4 g per tonne. The affected pigs were anorexic and showed signs of weakness, depression, ataxia, and incoordination to the point of recumbency, without paddling or other neurological...
