Rams are typically mated at about 2.5 years old, depending on the age of the sheep, plus consideration as to the size and type of mating paddocks. [33] The mating period ranges from about 6 to 8 weeks in commercial flocks. Longer mating times result in management problems with lamb marking and shearing etc. [32]
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).
Oviparity occurs in all birds, most reptiles, some fishes, and most arthropods. Among mammals , monotremes (four species of echidna , and the platypus ) are uniquely oviparous. In all but special cases of both ovuliparity and oviparity, the overwhelming source of nourishment for the embryo is the nutrients stored in the yolk, pre-deposited in ...
One-day-old chicks arriving to be unpacked and placed in shed Young birds being reared in a closed broiler house. Artificial selection has led to a great increase in the speed with which broilers develop and reach slaughter-weight. The time required to reach 1.5 kg (3 lb 5 oz) live-weight decreased from 120 days to 30 days between 1925 and 2005.
Sheep meat and milk were one of the earliest staple proteins consumed by human civilization after the transition from hunting and gathering to agriculture. [24] Sheep meat prepared for food is known as either mutton or lamb, and approximately 540 million sheep are slaughtered each year for meat worldwide. [147] "
Under modern farming methods, meat chickens reared indoors reach slaughter weight at 5 to 9 weeks of age, as they have been selectively bred to do so. In the first week of a broiler's life, it can grow up to 300 percent of its body size. A nine-week-old broiler averages over 9 pounds (4 kg) in body weight.
The meat of a lamb is taken from the animal between one month and one year old, with a carcass weight of between 5.5 and 30 kg (12 and 66 lb). This meat generally is more tender than that from older sheep and appears more often on tables in some Western countries .
