| Abstract | ||
| On February 1998 veterinary attention was requested for cases of staggering and convulsion in growing lambs fed upon 1.5% urea supplemented ration. The cases had been treated as urea toxicity using 6% acetic acid orally, two days previously without any response. Keen clinical examination was performed, lambs showed erected ears, opisthotonus , obvious termors and tetany of the limbs followed by clonic convulsions. There were tachypnea and tachycardia without change in rectal temperature the clinical signs began two hours post feeding. Ruminal pH and ammonia nitrogen were higher than normal, serum magnesium, calcium and inorganic phosphorous were lower than normal. Acetylcholinesterasce, was almost within normal activity, Ration was chemically analyzed and calculated quantitatively and qualitatively. The condition was diagnosod clinically and confirmed biochemically as hypomagnesemic tetany attributed to sudden and acute elevation of ruminal ammonia nitrogen sequalae to feeding of 1.5 % urea supplemented ration. The disorder was treated by injecting each lamb with 50 ml of Cal. D.Mag I/V., followed by 20 ml of 20% magnesium sulphate S/C, 5 ml of tonophosphan I/M and 1 ampule, of neurazine (choloropromazine Hcl 50 mg) I/M. The condition was controlled by lowering urea level to 1% and elevation of digestable energy of the ration, beside the addition of magnesium, calcium and phosphorous supplement. | ||
