Animal husbandry is the scientific management of

• Animal husbandry is the management of farm animals where farm rearing, feeding, caringand breeding of farm animals is done. It also includes caring and grooming livestock (domestic animals) that are raised to produce food and fiber like a cow for milk, chicken for meat and eggs, and pig for meat. • Animal husbandry also takes care of the proper breeding of domesticated animals with desirable characteristics that allow the creation and maintenance of a good generation of animals. • The breeding, rearing, and transplantation of fish by artificial means is called pisciculture, in other words, fish farming. • Therefore, the correct answer is option D.

An animal is in a good state of welfare if (as indicated by scientific evidence) it is healthy, comfortable, well-nourished, safe, able to express innate behavior, and if it is not suffering from unpleasant states such as pain, fear, and distress. Good animal welfare requires disease prevention and veterinary treatment, appropriate shelter, management, nutrition, humane handling, and humane slaughter. Animal welfare refers to the state of the animal; the treatment that an animal receives is covered by other terms such as animal care, animal husbandry, and humane treatment. Protecting an animal's we...

2 Animal Environment, Housing, and Management Proper housing and management of animal facilities are essential to animal well-being, to the quality of research data and teaching or testing programs in which animals are used, and to the health and safety of personnel. A good management program provides the environment, housing, and care that permit animals to grow, mature, reproduce, and maintain good health; provides for their well-being; and minimizes variations that can affect research results. Specific operating practices depend on many factors that are peculiar to individual institutions and situations. Well-trained and motivated personnel can often ensure high-quality animal care, even in institutions with less than optimal physical plants or equipment. Many factors should be considered in planning for adequate and appropriate physical and social environment, housing, space, and management. These include • The species, strain, and breed of the animal and individual characteristics, such as sex, age, size, behavior, experiences, and health. • The ability of the animals to form social groups with conspecifics through sight, smell, and possibly contact, whether the animals are maintained singly or in groups. • The design and construction of housing. • The availability or suitability of enrichments. • The project goals and experimental design (e.g., production, breeding, research, testing, and teaching). • The intensity of animal manipulation and invasiveness of the proce...

Abstract If the scientist needs to contact the animal facility after any study to inquire about husbandry details, this represents a lost opportunity, which can ultimately interfere with the study results and their interpretation. There is a clear tendency for authors to describe methodological procedures down to the smallest detail, but at the same time to provide minimal information on animals and their husbandry. Controlling all major variables as far as possible is the key issue when establishing an experimental design. The other common mechanism affecting study results is a change in the variation. Factors causing bias or variation changes are also detectable within husbandry. Our lives and the lives of animals are governed by cycles: the seasons, the reproductive cycle, the weekend-working days, the cage change/room sanitation cycle, and the diurnal rhythm. Some of these may be attributable to routine husbandry, and the rest are cycles, which may be affected by husbandry procedures. Other issues to be considered are consequences of in-house transport, restrictions caused by caging, randomization of cage location, the physical environment inside the cage, the acoustic environment audible to animals, olfactory environment, materials in the cage, cage complexity, feeding regimens, kinship, and humans. Laboratory animal husbandry issues are an integral but underappreciated part of investigators' experimental design, which if ignored can cause major interference with the ...

Animal Husbandry Indeed, animal husbandry plays a key role by valorizing flows of nonconsumable plant biomass, producing high nutritional value feed from them and maintaining soil carbon content and soil fertility, as manure from livestock is a source of organic matter, nitrogen, and phosphorus. From: New Aspects of Meat Quality (Second Edition), 2022 Related terms: • Agricultural Science • Antimicrobial Resistance • Animal Welfare • Pig • Farm Animal • Sorghum Animal husbandry is responsible for most of the NH 3 that is emitted into the atmosphere and subsequently deposited elsewhere. Critical loads of NH 3 deposition on natural ecosystems are exceeded in many countries with high animal densities. As a consequence, soil eutrophication and acidification occur. Eutrophication has three main aspects: 1. Changes in the composition of the vegetation towards nitrogen-loving species 2. Nutrient imbalances in the soil, which increase the risk of damage to vegetation by drought, storms, frost, diseases and plagues 3. Surplus nitrogen in the form of nitrate leaching to the ground water and N 2O being produced The acidification aspect of NH 3 deposition is related to its nitrification in the soil, since hydrogen ions (H +) are produced (see eqn [1]). As a consequence, leaching of trace elements, such as aluminium, pollutes ground water. High NH 3 concentrations, as observed within a few hundred metres of animal production facilities (buildings, storages), can also cause directly vis...
