|Term||Explanation||Synonym / Example|
|Pea comb||Pea comb in poultry is a low comb with three low ridges. The middle ridge is higher than the other two. Pea comb is a dominant mutation in chickens that drastically reduces the size of the comb and wattles. It is an adaptive trait in cold climates as it reduces heat loss and makes the chicken less susceptible to frost lesions.||
|Peste des Petits Ruminants (PPR)||Also known as goat plague, PPR is caused by a virus closely related to the rinderpest virus, canine distemper virus, and the human measles virus. Morbidity up to 100 % and mortality rates between 20 and 90 % are common, except in endemic areas or when mild disease occurs.|
|Phenotype||The observable physical or biochemical characteristics of an organism, as determined by both genetic makeup and environmental influences.||
For example colours of feathers in a poultry bird.
|Pinna||Pinna is the ear or more precisely, the part of the ear that projects like a little wing from the head. In Latin, pinna means wing.|
|Plant litter||Plant litter is dead plant material, such as leaves, bark and twigs, that have fallen to the ground. As plant litter decomposes, nutrients are released in the environment.|
The feathers of a bird, including down, wings and body feathers and their distinctive markings or coloration patterns.
Plumage is often used to describe a bird’s different colorations at different times of the year, such as brighter, bolder colors during the breeding season (breeding plumage) and more muted, subtle colors during winter months (winter plumage). Many bird species molt one or more times a year, changing their plumage as new feathers emerge. Plumage can also vary depending on a bird’s gender and age.
|Polled Livestock||Polled livestock are animals without horns, of species that normally have them. The term refers both to breeds or strains which are naturally polled through selective breeding and also to naturally horned animals which have been dehorned.|
|Poultry||Chicken and other domesticated birds (ducks, quail, pheasants etc) reared for meat and eggs.|
Poultry litter or broiler litter is a mixture of poultry excreta, spilled feed, feathers, and material used as bedding in poultry operations. Common poultry bedding materials are wood shavings, sawdust, peanut hulls, shredded sugar cane, straw, and other dry, absorbent, low-cost organic materials. Sand is also occasionally used as bedding. After use, the litter consists primarily of poultry manure, but also contains the original litter material, feathers, and spilled feed.

Jackals, fox, mongoose, cats etc
|Putrefaction||One of the seven stages in the decomposition of the body of a dead animal. It can be viewed, in broad terms, as the decomposition of proteins, in a process that results in the eventual breakdown of cohesion between tissues and the liquefaction of most organs. The exact rate of putrefaction is dependent upon many factors, such as weather, exposure and location. (source Wikipedia)|
