Animal Science Terms - W

Wafers: fibrous materials compressed into a form having a cross-section measurement greater than its length. Exact dimensions and bulk density of wafered feeds will vary according to the processing equipment used

Walk: basic, four beat lateral gait

Warm-Blooded: Having a relatively warm body temperature that stays about the same regardless of changes in the surroundings. Birds and mammals are warm-blooded

Warren: where owners keep their herd of rabbits as a group in a large cage or enclosure

Wasty: a:) too much fat on the carcass; b:) an animal that has a paunchy-middle

Wasty Middled: indication of unfitness, loose skinned, fatty look, kind of like the rear end of an expecting cow

Water: chemical substance with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions, but it often co-exists on Earth with its solid state, ice, and gaseous state (water vapor or steam)

Water-soluble vitamins: sub-class of vitamins that includes B complex vitamins and vitamin C. Not normally supplemented for ruminants after 2 months of age because rumen microbes are thought to be able to manufacture enough to meet the animal's requirements

Wattle: small fleshy appendage attached on or near the throat area of the goat and which serves no known function

Weak Loined: weak in the top over the loin area (middle of back). This animal appears to have a sway in their back, as opposed to a strong or straight top, which is straight from the top of the shoulder to the curve of the tail head. These animals are usually loose structured and still sounder made than cattle that “bow their top” which tend to be straighter off both ends and have less flex to the hock, knee and pastern

Wean: separate nursing offspring from their mothers so that they no longer receive milk

Weaner or Weanling: animal that has been weaned from its mother or has stopped suckling its mother 

Wet chemistry: laboratory methods used to determine nutrient content of feeds directly by chemical means

Wether: male sheep or goat that has been castrated 

Whey: watery part of milk that separates from the curds during the cheese-making process. The composition of whey varies considerably, depending on the milk source and the manufacturing process involved. Typically it is rich in lactose, minerals, vitamins and protein

White Blood Cell: any of various white or colorless cells in the blood of vertebrate animals, many of which participate in the inflammatory and immune responses to protect the body against infection and the repair of injuries to tissues. White body cells are formed mainly in the bone marrow

White Muscle Disease: problem in young goats caused by a deficiency of selenium and/or vitamin E. It causes kids to be weak at birth and shortly after birth. The condition impairs the animals ability to transport oxygen properly and if not treated can result in death within 48 hrs of birth

Wool: textile fiber obtained from sheep and certain other animals,[1] including cashmere from goats, mohair from goats, qiviut from muskoxen, vicuña, alpaca, camel from animals in the camel family, and angora from rabbits. Wool has several qualities that distinguish it from hair or fur: it is crimped, it is elastic, and it grows in staples (clusters). The term wool is usually restricted to describing the fibrous protein derived from the specialized skin cells called follicles in sheep

Wool-blindness: when excessive wool growth interferes with a sheep's ability to see normally

Wormer: see Anthelmintic
