“…The degree of hazard would be expected to vary by compound ingested, species involved and type of application, as poisoning can occur by direct ingestion of bait (primary poisoning) or via consumption of poisoned rodents causing secondary poisoning (Newton et al, 1990). Based upon the results of this experiment it may be concluded that bromadiolone exposure leads to depletion of antioxidant defense mechanism and varying degree of changes in tissue architecture in layer birds.…”

This study was undertaken to evaluate the oxidative stress induced by bromadiolone toxicity in layers. Birds were divided into two groups. Control group (I) received bromadiolone free feed and group (II) was exposed to bromadiolone (5 mg/kg feed) for seven weeks. Blood samples and organs were collected at the end of the experiment. Bromadiolone exposure resulted in significant rise in lipid peroxidation (LPO) levels in erythrocyte and liver. In addition decreased (P<0.05) level of reduced glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT) activities were observed in erythrocyte and liver. Histopathological results revealed mild to severe type of necrosis and degenerative changes in heart and liver of bromadiolone intoxicated animals. In addition histopathological findings of tissues ovary, liver, heart and pancreas also showed generalized haemorrhage. It is therefore concluded that feeding of bromadiolone admixed feed lead to depletion of Vitamin K causing multifocal haemorrhages and oxidative stress and cellular damage in different tissues.

“…However, this interdependence points to another alarming threat to the owls. Chemical pesticides are used for rodent pest control which can affect the non-targeted wildlife (Kaukeinen 1982;Littrell 1990;Gillies & Pierce 1999;Newton & Wyllie 2002). Because the IEO has shown a dependence on the rodents, use of these rodent pesticides could affect IEO populations because of secondary poisoning.…”

Abstract:If the importance of wildlife in agricultural pest control through predation can be conveyed, it can play an important role in the conservation of wildlife. However, such a strategy needs to be backed with convincing data. We studied the habitat preference, diet and reproductive behavior of the Indian Eagle Owl (IEO) Bubo bengalensis in order to understand its role in agricultural pest control. The Owls preferred landscapes with a higher percentage of agriculture and fed on rodents, birds, reptiles, arachnids, insects and other prey species. Despite being a generalist feeder, its diet was dominated by agricultural pests, which contributed 88% of the total prey biomass. Out of the13 rodent prey species, which comprised a major part of the diet, seven were identified as major agricultural pests and were 98% of the total rodent biomass in the diet of the IEO. The dependence of the IEO on rodent pests was further reflected by positive correlation between rodent biomass consumed and the breeding success of the owl. The IEO, therefore, plays a positive role in the biological control of crop pests. However, owls spent a longer duration of time in agricultural habitats, where they also had higher productivity. Thus IEO may be subjected to anthropogenic activities, human contact and interference. Since this owl is still hunted due to superstitious beliefs, scientific evidence elucidating the importance of the IEO in agricultural pest control can be used for its conservation by educating the farming community.
