Ram lambs not intended for breeding are castrated, though some shepherds choose to avoid the procedure for ethical, economic or practical reasons. [1] Ram lambs that will be slaughtered or separated from ewes before sexual maturity are not usually castrated. [23] In most breeds, lambs' tails are docked for health reasons. [8]
The traditional modes of reproduction include oviparity, taken to be the ancestral condition, traditionally where either unfertilised oocytes or fertilised eggs are spawned, and viviparity traditionally including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body.
At some stage, blow-flies lay their eggs within moist and warm areas (breech region) of the sheep. Then, the maggots grow and eat away the live flesh of the sheep. This causes great distress and pain for the lamb. Sometimes lambs are also mulesed (triangular cuts to the skin around the lamb's anus). This is also carried out for the same reason.
The animals most commonly slaughtered for food are cattle and water buffalo, sheep, goats, pigs, deers, horses, rabbits, poultry (mainly chickens, turkeys, ducks and geese), insects (a commercial species is the house cricket), and increasingly, fish in the aquaculture industry (fish farming).
Carcases from these lambs usually weigh between 14 and 30 kg. Older weaned lambs which have not yet matured to become mutton are known as old-season lambs. Yearling lamb — a young sheep between 12 and 24 months old; Saltbush mutton – a term used in Australia for the meat of mature Merinos which have been allowed to graze on atriplex plants
Prey animals, sheep, goats, pigs and cattle, were progressively domesticated early in the history of agriculture. [3] Pigs were domesticated in the Near East between 8,500 and 8000 BC, [4] sheep and goats in or near the Fertile Crescent about 8,500 BC, [5] and cattle from wild aurochs in the areas of modern Turkey and Pakistan around 8,500 BC.

Jessica Long's 9-year-old didn't want her goat, Cedar, to be slaughtered at the county fair. Officials sent deputies with a search warrant to get it back.
They hold the eggs internally for several weeks, providing nutrients, and then lay them and cover them like birds. Like marsupial " joeys ", monotreme " puggles " are larval and fetus-like, [ 9 ] as like them they cannot expand their torso due to the presence of epipubic bones, forcing them to produce undeveloped young.
