A CDC infographic on how antibiotic-resistant bacteria have the potential to spread from farm animals. The use of antibiotics in the husbandry of livestock includes treatment when ill (therapeutic), treatment of a group of animals when at least one is diagnosed with clinical infection (metaphylaxis [1]), and preventative treatment (prophylaxis).
Testing revealed that chickens fed with a variety of vitamin B12 produced with the residue of a specific antibiotic grew 50% faster than chickens fed with B12 from a different source. [2] Further research confirmed that antibiotic use improved chicken health, resulting in increased egg production, lower mortality rates, and reduced illness.
Permethrin is a medication and an insecticide. [6] [7] As a medication, it is used to treat scabies and lice. [8] It is applied to the skin as a cream or lotion. [6] As an insecticide, it can be sprayed onto outer clothing or mosquito nets to kill the insects that touch them. [7] [9] Side effects include rash and irritation where it is applied. [8]
The most common methods are electrocution and CO 2 stunning for swine and captive bolt stunning for cattle, sheep, and goats. Of these methods of electrocution, electronarcosis has been widely acclaimed as the safest, most humane and most reliable as well as the surest way to stun the animal and render them insensitive to pain.
Poultry species which exhibit cannibalism are omnivores.For example, hens in the wild often scratch at the soil to search for seeds, insects and even larger animals such as lizards or young mice, [7] although they are mainly herbivorous in adulthood. [3]
Sheep and goats are both small ruminants with cosmopolitan distributions due to their being kept historically and in modern times as grazers both individually and in herds in return for their production of milk, wool, and meat. [1] As such, the diseases of these animals are of great economic importance to humans.
In another example, some types of fungicides used in peanut farming are only slightly toxic to birds and mammals, but may kill earthworms, which can in turn reduce populations of the birds and mammals that feed on them. [54] Some pesticides come in granular form. Wildlife may eat the granules, mistaking them for grains of food.
This ecological harm has consequences not only for the native animals in the affected water body but also for the water supply for people. [ 58 ] To dispose of animal waste and other pollutants, animal production farms often spray manure (often contaminated with potentially toxic bacteria) onto empty fields, called "spray-fields", via sprinkler ...
