Chronic Egg Laying
Chronic egg laying is a maladaptive, behavioural disorder commonly seen in pet birds which repeatedly lay clutches of infertile eggs in the absence of a mate. It is particularly common in cockatiels, budgerigars, lovebirds, macaws and amazon parrots. Birds exhibiting chronic egg laying behavior will frequently lay eggs one after the other without stopping to brood them once the typical clutch size for their particular species has been reached. Excessive egg laying places a strain on the hen's body, depleting resources such as calcium, protein and vitamins from her body and may lead to conditions such as egg binding, osteoporosis, seizures, prolapse of the oviduct, or peritonitis – which may lead to her death. Causes While a single specific cause is unknown, chronic egg laying is believed to be triggered by hormonal imbalances influenced by a series of external factors. As in the domestic chicken, female parrots are capable of producing eggs without the involvement of a male – ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cockatiel
The cockatiel (; ''Nymphicus hollandicus''), also known as the weero/weiro or quarrion, is a medium-sized parrot that is a member of its own branch of the cockatoo family endemic to Australia. They are prized as exotic household pets and companion parrots throughout the world and are relatively easy to breed compared to other parrots. As a caged bird, cockatiels are second in popularity only to the budgerigar. The cockatiel is the only member of the genus ''Nymphicus''. It was previously unclear whether the cockatiel is a crested parakeet or small cockatoo; however, more recent molecular studies have assigned it to its own subfamily, Nymphicinae. It is, therefore, now classified as the smallest subfamily of the Cacatuidae (cockatoo family). Cockatiels are native to Australia, favouring the Australian wetlands, scrublands, and bushlands. There are many different mutations of this bird. Taxonomy and etymology Originally described by J. F. Gmelin in an edition of Systema n ...

Domestic 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 their meat and 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 feature prominently in folklore, religion, and literature across many societies. Their economic importance makes them a central component of global animal husbandry and agriculture. Nomenclature Terms for chickens include: * ''Bid ...

Animal Reproductive System
The reproductive system of an organism, also known as the genital system, is the biological system made up of all the anatomical organs involved in sexual reproduction. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system. Unlike most organ systems, the sexes of differentiated species often have significant differences. These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness of the offspring.Reproductive System 2001 Body Guide powered by Adam Animals In mammals, the major organs of the reproductive system include the external |
Abnormal Behaviour In Animals
In psychology, abnormality (also dysfunctional behavior, maladaptive behavior, or deviant behavior) is a behavioral characteristic assigned to those with conditions that are regarded as dysfunctional. Behavior is considered to be abnormal when it is atypical or out of the ordinary, consists of undesirable behavior, and results in impairment in the individual's functioning. As applied to humans, abnormality may also encompass deviance, which refers to behavior that is considered to transgress social norms. The definition of abnormal behavior in humans is an often debated issue in abnormal psychology. ''Abnormal'' behavior should not be confused with ''unusual'' behavior. Behavior that is out of the ordinary is not necessarily indicative of a mental disorder. Abnormal behavior, on the other hand, while not a mental disorder in itself, is often an indicator of a possible mental or psychological disorder. A psychological disorder is defined as an "ongoing dysfunctional pattern of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deslorelin
Deslorelin, sold under the brand name Suprelorin among others, is an injectable gonadotropin releasing hormone superagonist (GnRH agonist) which is used in veterinary medicine for various indications. Uses Veterinary Deslorelin is used in veterinary medicine. One commercial form of deslorelin acetate is marketed by Peptech with the brand name Ovuplant. Another form is available in the United States, Sucromate Equine, which was FDA-approved for use in horses in November 2010. This is manufactured by Thorne BioScience LLC and was introduced to the United States market following the withdrawal of Ovuplant. The deslorelin products are currently approved for use in veterinary medicine and to promote ovulation in mares as part of the artificial insemination process. It is also used to stabilize high-risk pregnancies, mainly of livestock.

Leuprolide Acetate
Leuprorelin, also known as leuprolide, is a manufactured version of a hormone used to treat prostate cancer, breast cancer, endometriosis, uterine fibroids, for early puberty, as part of transgender hormone therapy, or to perform chemical castration of violent sex offenders. It is given by injection into a muscle or under the skin. Leuprorelin is in the gonadotropin-releasing hormone (GnRH) analogue family of medications. It works by decreasing gonadotropins and therefore decreasing testosterone and estradiol. Common side effects include hot flashes, unstable mood, trouble sleeping, headaches, and pain at the site of injection. Other side effects may include high blood sugar, allergic reactions, and problems with the pituitary gland. Use during pregnancy may harm foetal development. Leuprorelin was patented in 1973 and approved for medical use in the United States in 1985. It is on the World Health Organization's List of Essential Medicines. It is sold under the brand nam ...

Neutering
Neutering, from the Latin ('of neither sex'), is the removal of a non-human animal's sex organ, reproductive organ, either all of it or a considerably large part. The male-specific term is castration, while spaying is usually reserved for female animals. Colloquially, both terms are often referred to as fixing. In male horses, castrating is referred to as gelding. An animal that has not been neutered is sometimes referred to as entire or intact. Often the term ''neuter[ing]'' is used to specifically mean castration, e.g. in phrases like "spay and neuter". Neutering is the most common method for animal Sterilization (medicine), sterilization. humane society, Humane societies, animal shelters, and rescue groups urge pet owners to have their pets neutered to prevent the births of unwanted Litter (zoology), litters, which contribute to the Overpopulation of domestic pets, overpopulation of unwanted animals in the rescue system.

Peritonitis
Peritonitis is inflammation of the localized or generalized peritoneum, the lining of the inner wall of the abdomen and covering of the abdominal organs. Symptoms may include severe pain, swelling of the abdomen, fever, or weight loss. One part or the entire abdomen may be tender. Complications may include shock and acute respiratory distress syndrome. Causes include perforation of the intestinal tract, pancreatitis, pelvic inflammatory disease, stomach ulcer, cirrhosis, a ruptured appendix or even a perforated gallbladder. Risk factors include ascites (the abnormal build-up of fluid in the abdomen) and peritoneal dialysis. Diagnosis is generally based on examination, blood tests, and medical imaging. Treatment often includes antibiotics, intravenous fluids, pain medication, and surgery. Other measures may include a nasogastric tube or blood transfusion. Without treatment death may occur within a few days. About 20% of people with cirrhosis who are hospitalized ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Budgerigar
The budgerigar ( ; ''Melopsittacus undulatus''), also known as the common parakeet, shell parakeet or budgie ( ), is a small, long-tailed, seed-eating parrot native to Australia. Naturally the species is green and yellow with black, scalloped markings on the nape, back, and wings. Budgies are bred in captivity with colouring of blues, whites, yellows, greys, and even with small crests. Juveniles and chicks are monomorphic (the sexes are visually indistinguishable), while adults are told apart by their cere colouring and their behaviour. The species is monotypic, meaning it is the only member of the genus ''Melopsittacus'', which is the only genus in the Melopsittacini tribe. The budgerigar is closely related to lories and the fig parrots. The origin of the budgerigar's name is unclear. First recorded in 1805, budgerigars are popular pets around the world due to their small size, low cost, and ability to mimic human speech. They are likely the third most popular pet in ...

Oviduct
The oviduct in vertebrates is the passageway from an ovary. In human females, this is more usually known as the fallopian tube. The eggs travel along the oviduct. These eggs will either be fertilized by spermatozoa to become a zygote, or will degenerate in the body. Normally, these are paired structures, but in birds and some cartilaginous fishes, one or the other side fails to develop (together with the corresponding ovary), and only one functional oviduct can be found. Except in teleosts, the oviduct is not directly in contact with the ovary. Instead, the most anterior portion ends in a funnel-shaped structure called the infundibulum, which collects eggs as they are released by the ovary into the body cavity. The only female vertebrates to lack oviducts are the jawless fishes. In these species, the single fused ovary releases eggs directly into the body cavity. The fish eventually extrudes the eggs through a small genital pore towards the rear of the body. Fish and amphibia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seizure
A seizure is a sudden, brief disruption of brain activity caused by abnormal, excessive, or synchronous neuronal firing. Depending on the regions of the brain involved, seizures can lead to changes in movement, sensation, behavior, awareness, or consciousness. Symptoms vary widely. Some seizures involve subtle changes, such as brief lapses in attention or awareness (as seen in absence seizures), while others cause generalized convulsions with loss of consciousness ( tonic–clonic seizures). Most seizures last less than two minutes and are followed by a postictal period of confusion, fatigue, or other symptoms. A seizure lasting longer than five minutes is a medical emergency known as status epilepticus. Seizures are classified as provoked, when triggered by a known cause such as fever, head trauma, or metabolic imbalance, or unprovoked, when no immediate trigger is identified. Recurrent unprovoked seizures define the neurological condition epilepsy. Clinical features Seizur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
