Aggression In Cattle
Aggression in cattle is usually a result of fear, learning, and hormonal state, however, many other factors can contribute to aggressive behaviors in cattle. Temperament traits Temperament traits are known to be traits in which explain the behavior and actions of an animal and can be described in the traits responsible for how easily an animal can be approached, handled, milked, or trained. Temperament can also be defined as how an animal carries out maternal or other behaviors while subjected to routine management. These traits have the ability to change as the animal ages or as the environment in which the animal lives changes over time, however, it is proven that regardless of age and environmental conditions, some individuals remain more aggressive than others. Aggression in cattle can arise from both genetic and environmental factors. Aggression between cows is worse than that between bulls. Bulls with horns will bunt (push or strike with the horns) in which can cause more ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fear
Fear is an intensely unpleasant emotion in response to perceiving or recognizing a danger or threat. Fear causes physiological changes that may produce behavioral reactions such as mounting an aggressive response or fleeing the threat. Fear in human beings may occur in response to a certain stimulus occurring in the present, or in anticipation or expectation of a future threat perceived as a risk to oneself. The fear response arises from the perception of danger leading to confrontation with or escape from/avoiding the threat (also known as the fight-or-flight response), which in extreme cases of fear (horror and terror) can be a freeze response or paralysis. In humans and other animals, fear is modulated by the process of cognition and learning. Thus, fear is judged as rational or appropriate and irrational or inappropriate. An irrational fear is called a phobia. Fear is closely related to the emotion anxiety, which occurs as the result of threats that are perceived to b ...

Livestock
Livestock are the domesticated animals raised in an agricultural setting to provide labor and produce diversified products for consumption such as meat, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to animals who are raised for consumption, and sometimes used to refer solely to farmed ruminants, such as cattle, sheep, goats and pigs. Horses are considered livestock in the United States. The USDA classifies pork, veal, beef, and lamb (mutton) as livestock, and all livestock as red meat. Poultry and fish are not included in the category. The breeding, maintenance, slaughter and general subjugation of livestock, called '' animal husbandry'', is a part of modern agriculture and has been practiced in many cultures since humanity's transition to farming from hunter-gatherer lifestyles. Animal husbandry practices have varied widely across cultures and time periods. It continues to play a major economic and cultural role in numerous communities. Lives ...

Physical Disability
A physical disability is a limitation on a person's physical functioning, mobility, dexterity or stamina. Other physical disabilities include impairments which limit other facets of daily living, such as respiratory disorders, blindness, epilepsy and sleep disorders. Causes Prenatal disabilities are acquired before birth. These may be due to diseases or substances that the mother has been exposed to during pregnancy, embryonic or fetal developmental accidents or genetic disorders. Perinatal disabilities are acquired between some weeks before to up to four weeks after birth in humans. These can be due to prolonged lack of oxygen or obstruction of the respiratory tract, damage to the brain during birth (due to the accidental misuse of forceps, for example) or the baby being born prematurely. These may also be caused due to genetic disorders or accidents. Post-natal disabilities are gained after birth. They can be due to accidents, injuries, obesity, infection or other illness ...

Mastitis
Mastitis is inflammation of the breast or udder, usually associated with breastfeeding. Symptoms typically include local pain and redness. There is often an associated fever and general soreness. Onset is typically fairly rapid and usually occurs within the first few months of delivery. Complications can include abscess formation. Risk factors include poor latch, cracked nipples, use of a breast pump, and weaning. The bacteria most commonly involved are '' Staphylococcus'' and '' Streptococci''. Diagnosis is typically based on symptoms. Ultrasound may be useful for detecting a potential abscess. Prevention is by proper breastfeeding techniques. When infection is present, antibiotics such as cephalexin may be recommended. Breastfeeding should typically be continued, as emptying the breast is important for healing. Tentative evidence supports benefits from probiotics. About 10% of breastfeeding women are affected. Types When it occurs in breastfeeding mothers, it is known as puer ...

Castration
Castration is any action, surgical, chemical, or otherwise, by which an individual loses use of the testicles: the male gonad. Surgical castration is bilateral orchiectomy (excision of both testicles), while chemical castration uses pharmaceutical drugs to deactivate the testes. Castration causes sterilization (preventing the castrated person or animal from reproducing); it also greatly reduces the production of hormones, such as testosterone and estrogen. Surgical castration in animals is often called neutering. The term ''castration'' is sometimes also used to refer to the removal of the ovaries in the female, otherwise known as an oophorectomy, or the removal of internal testes, otherwise known as gonadectomy. The equivalent of castration for female animals is spaying. Estrogen levels drop following oophorectomy, and long-term effects of the reduction of sex hormones are significant throughout the body. Castration of animals is intended to favor a desired development of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Docking (animal)
Docking is the intentional removal of part of an animal's tail or, sometimes, ears. The term cropping is more commonly used in reference to the cropping of ears, while ''docking'' more commonly—but not exclusively—refers to the tail. The term tailing is also commonly used. The term arises because the living flesh of the tail, from which the animal's tail hairs grow, commonly is known as the dock. Pigs Tail-docking in pigs is typically carried out without anaesthetic when the piglet is three to four days old and causes acute trauma and pain. Commercially raised domestic pigs kept in close quarters have their tails docked to prevent chewing or biting each other's tails. Pig producers in Brazil and Thailand have stopped tail docking for animal welfare reasons. Routine tail-docking without anesthesia is illegal in the EU. The practice continues among large US pig producers. Sheep Many breeds of sheep have their tails docked to reduce the buildup of faeces which can enco ...

Livestock Dehorning
Dehorning is the process of removing the horns of livestock. Cattle, sheep, and goats are sometimes dehorned for economic and safety reasons. Disbudding is a different process with similar results; it cauterizes and thus destroys horn buds before they have grown into horns. Disbudding is commonly performed early in an animal's life, as are other procedures such as docking and castration. In some cases, it can be unnecessary. Many breeds of cattle and sheep are naturally hornless. The polled gene can occur naturally in particular breeds or easily manipulated during breeding to lack horns, therefore do not need to be dehorned or disbudded. Although polling is common among cattle and sheep, a variety of livestock species cannot easily be bred to lack horns naturally. In one case, the poll gene in goats was linked to hermaphrodism in a single study several decades ago, although fertile polled goats have been bred. Horns are removed because they can pose a risk to humans, other ani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pain
Pain is a distressing feeling often caused by intense or damaging stimuli. The International Association for the Study of Pain defines pain as "an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage." In medical diagnosis, pain is regarded as a symptom of an underlying condition. Pain motivates the individual to withdraw from damaging situations, to protect a damaged body part while it heals, and to avoid similar experiences in the future. Most pain resolves once the noxious stimulus is removed and the body has healed, but it may persist despite removal of the stimulus and apparent healing of the body. Sometimes pain arises in the absence of any detectable stimulus, damage or disease. Pain is the most common reason for physician consultation in most developed countries. It is a major symptom in many medical conditions, and can interfere with a person's quality of life and general functioning. Simple ...

Stressor
A stressor is a chemical or biological agent, environmental condition, external stimulus or an event seen as causing stress to an organism. Psychologically speaking, a stressor can be events or environments that individuals might consider demanding, challenging, and/or threatening individual safety.Deckers, Lambert (2018). Motivation Biological, Psychological, and Environmental. New York, NY: Routledge. pp. 208-212. . Events or objects that may trigger a stress response may include: * environmental stressors ( hypo or hyper-thermic temperatures, elevated sound levels, over-illumination, overcrowding) * daily "stress" events (e.g., traffic, lost keys, money, quality and quantity of physical activity) * life changes (e.g., divorce, bereavement) * workplace stressors (e.g., high job demand vs. low job control, repeated or sustained exertions, forceful exertions, extreme postures, office clutter) * chemical stressors (e.g., tobacco, alcohol, drugs) * social stressor (e.g., socie ...

Temperature
Temperature is a physical quantity that expresses quantitatively the perceptions of hotness and coldness. Temperature is measured with a thermometer. Thermometers are calibrated in various temperature scales that historically have relied on various reference points and thermometric substances for definition. The most common scales are the Celsius scale with the unit symbol °C (formerly called ''centigrade''), the Fahrenheit scale (°F), and the Kelvin scale (K), the latter being used predominantly for scientific purposes. The kelvin is one of the seven base units in the International System of Units (SI). Absolute zero, i.e., zero kelvin or −273.15 °C, is the lowest point in the thermodynamic temperature scale. Experimentally, it can be approached very closely but not actually reached, as recognized in the third law of thermodynamics. It would be impossible to extract energy as heat from a body at that temperature. Temperature is important in all fields of natur ...

Hypothalamic–pituitary–adrenal Axis
The hypothalamic–pituitary–adrenal axis (HPA axis or HTPA axis) is a complex set of direct influences and feedback interactions among three components: the hypothalamus (a part of the brain located below the thalamus), the pituitary gland (a pea-shaped structure located below the hypothalamus), and the adrenal (also called "suprarenal") glands (small, conical organs on top of the kidneys). These organs and their interactions constitute the HPA axis. The HPA axis is a major neuroendocrine system that controls reactions to stress and regulates many body processes, including digestion, the immune system, mood and emotions, sexuality, and energy storage and expenditure. It is the common mechanism for interactions among glands, hormones, and parts of the midbrain that mediate the general adaptation syndrome (GAS). While steroid hormones are produced mainly in vertebrates, the physiological role of the HPA axis and corticosteroids in stress response is so fundamental that anal ...

Sleep Deprivation
Sleep deprivation, also known as sleep insufficiency or sleeplessness, is the condition of not having adequate duration and/or quality of sleep to support decent alertness, performance, and health. It can be either chronic or acute and may vary widely in severity. Acute sleep deprivation is when an individual sleeps less than usual or does not sleep at all for a short period of time – usually lasting one to two days. Chronic sleep deprivation means when an individual routinely sleeps less than an optimal amount for ideal functioning. Chronic sleep deficiency is often confused with the term insomnia. Although both chronic sleep deficiency and insomnia share decreased quantity and/or quality of sleep as well as impaired function, their difference lies in the ability to fall asleep. Sleep deprived individuals are able to fall asleep rapidly when allowed but those with insomnia have difficulty falling asleep. The average adult needs seven or more hours of sleep per night to mainta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
