Bt cotton spells doom for cattle?

ADILABAD: Grazing on residual Bt cotton crop seems to have resulted in the death of over 200 animals in various mandals of the district in the last two months. The Animal Husbandry Department has sounded an alarm as the number of sick animals with somewhat classic poisoning symptoms has kept increasing.

It is a practice among the farming community, especially in the cotton-intensive areas, to use residual crops as fodder. As the area under Bt cotton had increased substantially this year, large tracts under the crop were available for use as fodder after harvesting ended in December-January.

Acute in many mandals

“In all the cases where animals were treated for suspected Bt cotton poisoning, the animals showed symptoms like convulsions, nasal discharge, vomiting, respiratory problems and diarrhoea,” K. Shravan Kumar, veterinary assistant surgeon, said.

The problem is acute in mandals like Tamsi, Bazarhatnoor, Sirpur(U), Gudihatnoor, Talamadugu and Bela. A. Vinod, veterinary assistant surgeon at Tamsi, said the problem came to their notice in January. “We are opting for symptomatic treatment so long as the ‘culprit’ toxic substance is not identified. Timely treatment can save a few animals in our mandal,” he said.

“Another bullock died in Talamadugu recently. We have sent the extracted feed material after a post-mortem on the animal and leaves, stem and other material from the suspected plants for analysis at the Veterinary Biological Research Institute in Hyderabad,” Y. Sanjiv Reddy, veterinary assistant surgeon at Talamadugu, said.

Having noticed similar deaths of sheep from other districts, the Animal Husbandry Directorate issued a circular this month to veterinary hospitals asking them to send relevant material for analysis. “However, it needs more than an analysis to curb the occurrence of animal deaths due to suspected poisoning,” a veterinarian observed.
