Although this is one thing we do not like to happen, it is unfortunate that at some point, our lovely pets may pass on, and disposing of their precious bodies appropriately will indeed help save ourselves and our environment from the impending danger that could be associated with inappropriate disposal. Appropriate disposal of dead livestock is actually important to help protect humans and livestock.
Regardless of the type of animal, its carcass may contain bacteria and other disease organisms that have the ability to infect humans either directly or through the contamination of a residential water supply. Carcasses may either be disposed of by sending them to knackeries, through burial, or through burning.
Burial Method.: Buring an animal is the most common method of disposing of the dead body of an animal, and it is a fairly safe activity, the burial pit has to be dug 2 meters deep or has the highest part of the carcass at least 1.5 meters below the surrounding terrain. Asides from the carcass of the dead animal, leftover feed, the excreta, including the bedding of the dead animal should be buried alongside, especially when one isn't sure of the cause of the demise.
Carrying out deep burial is a necessity, as it would prevent jackals from digging up carcasses, and insects from moving bacterial spores to the surface. Once car the carcass gets into the grave, the skin should be slashed and then get drenched with crude phenol, afterwards, the carcass has to be covered up on all sides with quick lime filled with mud and topped up with certain concrete objects. In the case of anthrax, before the carcass is removed for disposal, all orifices are plugged with cotton soaked in 5% of cresol, and the body is wrapped in a similar soaked bag as well.
Chemical Treatment: When an animal dies from a disease and it does not pose any threat or hazard by a usual means, then the area needs to be treated with lime water or with a suspension of bleaching powder.
Burning/Incineration: Burning is an efficient way of deposing carcasses effectively, it could be done in an incinerator where the temperature is about 600-800C, when this temperature is reached, all organisms are destroyed, this method is advisable for animals that have passed due to microorganisms that are resistant to heat. In a case where there is no incinerator, the dead animal could be burned in a pit, probably a pit dug close to the point of death.
The pit could be filled with wood, creating air spaces with the help of cross iron bars, then the carcass would be placed and further ignited with kerosene, after the carcass has been burnt, then the trench should be filled up with mud.
After an animal may have died due to apparent disease, then every material and item that could serve as an agent of contamination, if they cannot be disposed of, then they should be disinfected. All bedding materials and other items should either be burned or disinfected appropriately. Some pet owners or animal owners may underrate the need to appropriately dispose of a dead animal, just maybe you are one of those who may be in doubt, but I will like to take you through some of the things that happen after the unfortunate demise of an animal.
The moment an animal dies, what comes out of its body are fluids from the bladder and large intestines, the eyes of the animal then turn a cloudy shade of gray as the usual process for maintaining the health of the eye is no longer functioning, the tongue of the animal also could probably hang out of its mouth, in this case, there is no overpowering smell or any stiff muscle just. If you however, leave this dead animal for some extra hours without disposal, you will begin to notice skin discoloration like dark or purple splotches, the time for decoloration is also dependent on the size of the animal, within those spare minutes or hours as well, germs and bacteria would make no official announcement before they begin to infest the carcass.
When a carcass is left for 24 hours, the smell becomes very obvious, then the body begins to dry out and cool, if left beyond 24 hours, bugs and flies will begin to crawl on the carcass, and white maggots may be physically seen feasting on the carcass, at this point, in order to get rid of the body, those who are skilled with the act of dead animal removal will need to come to help you as it cannot be done alone.
