Nitrates can cause difficulty breathing, but it is usually a sudden inabilitiy to breathe along with severe tremors, weakness, convulsions and sudden death. Is your herd showing any of these other clinical signs? One definitive way to diagnose nitrate poisoning is by taking a blood sample, and the blood will resemble a chocolate color.
Is your herd showing any other signs of pneumonia, such as fever, nasal discharge, coughing, etc?
Has your vet suggested nitrates as a possibility?
Looking forward to your reply.
have all your cattle got sick with the same symptoms or is it that you feel they might. in any case do you have a vaccination history of the cattle pls do reply with the history of vaccination and their schedules,
waiting for your reply ,
hi jay ,
if you can , please get them vaccinated against the H.S as most of the cattle prone to the respiratory infections in free range system . also if was raining a week or fortnight ago, also suggested if the recrtal temperatures can assist me further daignosing the disease , thank you
since the rectal tempretures can possibly indicate wether they have associated bacterial infection . further more its advisable to use quinolones if you find temperature elevated .and remain on course of antibiotics for several days till fully recovered
The bull seems to be getting better. His breathing has returned to
normal and is eating and drinking a bit. We lost the other cow yesterday. Have determined that it might be the hay so we have taken them off that hay and just watching him. The steroid shots he got are probably what saved him. I will investigate vaccinating the cows against HS in the future. Thanks
sorry to hear that you lost your cow,steroids do help but its advisable to use a antibiotic withgood distribution volumes like enrofloxacin or ciprofloxacin invariably the normal commensale bacteria (pasturella)present in the respiratory tract which usually is not harmful becomes pathogenic and aggrevates the situation causing distressed and laboured breating. this can occur when the animals have low immune levels use of levamisole @2.5 mg /kg body weight has immunomodulation effects .
