Henopause
Henopause, a portmanteau of "hen" and "menopause", is sometimes used to refer to the point at which hens stop laying egg An egg is an organic vessel grown by an animal to carry a possibly fertilized egg cell (a zygote) and to incubate from it an embryo within the egg until the embryo has become an animal fetus that can survive on its own, at which point the ...s. Description Although daily egg production starts to tail off after one year old, it may continue until 5–7 years old. Older hens gradually produce fewer eggs, and the eggs are usually larger. Since the average lifespan of a pet layer hen is 8–15 years, henopause has received attention as a potential problem for backyard or urban chicken farmers who are eventually faced with the decision to either slaughter older layers or keep them as non-producing pets. In the UK, the British Hen Welfare Trust charity rescues commercial hens who would otherwise be sent to slaughter when they become no longer commercially ...

Egg Farming
Poultry farming is the form of animal husbandry which raises domesticated birds such as chickens, ducks, turkeys and geese to produce meat or eggs for food. Poultry – mostly chickens – are farmed in great numbers. More than 60 billion chickens are killed for consumption annually. Chickens raised for eggs are known as layers, while chickens raised for meat are called broilers. In the United States, the national organization overseeing poultry production is the Food and Drug Administration (FDA). In the UK, the national organization is the Department for Environment, Food and Rural Affairs (DEFRA). Intensive and alternative According to the World Watch Institute, 74 percent of the world's poultry meat, and 68 percent of eggs are produced intensively.''State of the World 2006'' World Watch Institute, p. 26 One alternative to intensive poultry farming is free-range farming using lower stocking densities. Poultry producers routinely use nationally approved medications, suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portmanteau
In linguistics, a blend—also known as a blend word, lexical blend, or portmanteau—is a word formed by combining the meanings, and parts of the sounds, of two or more words together.Garner's Modern American Usage p. 644. English examples include '' smog'', coined by blending ''smoke'' and ''fog'', and '''', from ''motor'' ('' motorist'') and ''hotel''. A blend is similar to a [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Menopause
Menopause, also known as the climacteric, is the time when Menstruation, menstrual periods permanently stop, marking the end of the Human reproduction, reproductive stage for the female human. It typically occurs between the ages of 45 and 55, although the exact timing can vary. Menopause is usually a natural change related to a decrease in circulating blood estrogen levels. It can occur earlier in those who smoke tobacco. Other causes include surgery that removes both ovaries, some types of chemotherapy, or anything that leads to a decrease in hormone levels. At the physiological level, menopause happens because of a decrease in the ovaries' production of the hormones estrogen and progesterone. While typically not needed, measuring hormone levels in the blood or urine can confirm a diagnosis. Menopause is the opposite of menarche, the time when periods start. In the years before menopause, a woman's periods typically become irregular, which means that periods may be longer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chicken
The chicken (''Gallus gallus domesticus'') is a domesticated subspecies of the red junglefowl (''Gallus gallus''), originally native to Southeast Asia. It was first domesticated around 8,000 years ago and is now one of the most common and widespread domesticated animals in the world. Chickens are primarily kept for chicken as food, their meat and egg as food, eggs, though they are also kept as pets. As of 2023, the global chicken population exceeds 26.5 billion, with more than 50 billion birds produced annually for consumption. Specialized breeds such as broilers and laying hens have been developed for meat and egg production, respectively. A hen bred for laying can produce over 300 eggs per year. Chickens are social animals with complex vocalizations and behaviors, and cultural references to chickens, feature prominently in folklore, religion, and literature across many societies. Their economic importance makes them a central component of global animal husbandry and agricu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urban Chicken Keeping
Urban keeping of chickens as pets, for eggs, meat, or for eating pests is popular in urban and suburban areas. Some people sell the eggs for side income. Keeping chickens in an urban environment is a type of urban agriculture, important in the local food movement, which is the growing practice of cultivating, processing and distributing food in or around a village, town or city. According to National Sustainable Agriculture Information Service and experts in backyard agriculture, there are a host of personal benefits associated with urban agriculture and keeping chickens in one's own backyard. Additionally, there is a growing number of people (including in urban environments) who are adopting ex-commercial hens – interrupting their usual destination of the slaughterhouse when the egg farming industry no longer wants them (typically at around the age of 1.5 years).Mace, Jenny L., and Andrew Knight. 2024.

British Hen Welfare Trust
The British Hen Welfare Trust (formerly the Battery Hen Welfare Trust) is the United Kingdom's first registered charity solely for laying hens. It was founded in April 2005 by Jane Howorth, and was established in order to raise awareness of the 20 million hens kept in cages in the UK at that time. Its activities include collecting hens which have reached the end of their commercial lives and re-homing them as pets. The charity's headquarters are near Rose Ash, North Devon. Aims The aim of the charity is to reduce consumer demand for caged ( factory farmed) eggs, while encouraging support for the British egg industry. This also includes educating consumers about processed foods which contain eggs, such as: cake, pasta, chocolates ( fondant filled), quiche, ready-made Yorkshire puddings, ready-made pancakes, biscuits, ready meals (TV dinners), and noodles. As of 2016, approximately 46% of UK battery eggs are used by food manufacturers and in the leisure industry. The BHWT re- ...

Forced Molting
Forced molting, sometimes known as induced molting, is the practice by some poultry industries of artificially provoking a flock to molt simultaneously, typically by withdrawing food for 7–14 days and sometimes also withdrawing water for an extended period. Forced molting is usually implemented when egg-production is naturally decreasing toward the end of the first egg-laying phase. During the forced molt, the birds cease producing eggs for at least two weeks, which allows the bird's reproductive tracts to regress and rejuvenate. After the molt, the hen's egg production rate usually peaks slightly lower than the previous peak, but egg quality is improved. The purpose of forced molting is therefore to increase egg production, egg quality, and profitability of flocks in their second or subsequent laying phases, by not allowing the hen's body the necessary time to rejuvenate during the natural cycle of feather replenishment. The practice is controversial. While it is widespread in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eggs (food)
Humans and other hominids have consumed eggs for millions of years. The most widely consumed eggs are those of fowl, especially chickens. People in Southeast Asia began harvesting chicken eggs for food by 1500 BCE. Eggs of other birds, such as ducks and ostriches, are eaten regularly but much less commonly than those of chickens. People may also eat the eggs of reptiles, amphibians, and fish. Fish eggs consumed as food are known as roe or caviar. Hens and other egg-laying creatures are raised throughout the world, and mass production of chicken eggs is a global industry. In 2009, an estimated 62.1 million metric tons of eggs were produced worldwide from a total laying flock of approximately 6.4 billion hens. There are issues of regional variation in demand and expectation, as well as current debates concerning methods of mass production. In 2012, the European Union banned battery husbandry of chickens.
