Asexual Reproduction

Asexual reproduction in animals occurs through fission, budding, fragmentation, and parthenogenesis.  Sexual reproduction starts with the combination of a sperm and an egg in a process called fertilization. This can occur either outside the bodies or inside the female. The method of fertilization varies among animals. Animal cells lack the rigid cell walls that characterize plant cells. The bodies of most animals (all except sponges) are made up of cells organized into tissues, each tissue specialized to some degree to perform specific functions. In most, tissues are organized into even more specialized organs. Most animals are capable of complex and relatively rapid movement compared to plants and other organisms. Most reproduce sexually, by means of differentiated eggs and sperm.

Farm Animal Medicines

Animal medicines are used in farm animals, like pets and people, to prevent and control disease and illness. Animal medicines are just as sophisticated and effective as human medicines. They are expensive to produce and licence for use in farm animals. Small animal veterinarians are increasingly taking on caseloads that include farm animals, with cases being presented by local hobby farmers, smallholders, and ‘novelty pet’ owners. Recognising this trend, this book provides a quick reference guide for small-animal orientated veterinarians in the basics of surgery and treatment of farm animals. Popular animals such as cattle, sheep, goats, camelids and backyard poultry are covered, and basic techniques such as anaesthesia, clinical examination techniques, breeding, surgery and euthanasia are discussed. This book provides a quick-reference format, ideal for looking up information during a consult, useful for veterinarians in small and mixed practices and those less familiar with animals such as alpacas which have seen an increase in popularity. Also ideal as a refresher guide and as a continuing professional development resource.

Food science

Food science is the study of the physical, biological, and chemical makeup of food; the causes of food deterioration; and the concepts underlying food processing. Food scientists and technologists apply scientific disciplines including chemistry, engineering, microbiology, and nutrition to the study of food to improve the safety, nutrition, wholesomeness and availability of food. Food technology is the application of food science to the selection, preservation, processing, packaging, distribution, and use of safe food. Related fields include analytical chemistry, biotechnology, engineering, nutrition, quality control, and food safety management.

Antibiotics use in Livestock Production

Largest changes is that animal producers are no longer able able to buy over the counter medicated feed if it contains antimicrobials important to human health. This means that all producers must work directly with veterinarians for permission to use medications such as antibiotics in feed only when necessary. Producers will also not be able to use antimicrobials in feed for the purpose of growth promotion or feed efficiency. The FDA has instituted these changes to help keep humans and animals safe and help prevent further antimicrobial resistance. It is important to remember that antibiotics are necessary to treat certain diseases and prevent poor animal welfare. Antibiotics are used in livestock production for two basic reasons: disease treatment and disease prevention. Just like humans, animals are prone to bacterial infections. As in human medicine, antibiotics are used to effectively treat those infections. In livestock production, antibiotics can also be used to prevent disease. There are times in an animal’s life, such as weaning, where certain diseases can be very common.

Animal Disease Diagnostics

Animal disease diagnostics is an important step between the cause and cure of disease. The cause of death is vital information when deciding a treatment plan for other animals. Animal disease diagnostics laboratories serve to improve animal health not only for production purposes, but for the entire area they serve. A laboratory’s priority is to diagnose all specimens on their premises, no matter if the specimen is a pet alpaca or a flock of turkeys.The importance of animal disease diagnostics laboratories is not a very recognized area of animal production but they are essential to animal health. It is important for not only animal producers, but also consumers to be aware of this resource. Whether a companion or a production animal, any owner can use an animal disease diagnostics lab to gain understanding and prevent similar circumstances in the future. Without disease diagnostics, food and animal safety would not be as reliable.

Vertebrate Zoology

Vertebrate zoology is the biological discipline that consists of the study of Vertebrate animals, i.e., animals with a backbone, such as fish, amphibians, reptiles, birds and mammals. oldest specimens date back to the 1840s, but most activity associated with vertebrates started in the 1870s. With the exception of the bird collection  and a portion of the fish collection, vertebrates are housed on the Sixth Floor  of the Museum. Besides collection areas, a lab area for specimen processing and examination is situated adjacent to the herpetology range. All of the collections in the department have been computerized.

Invertebrate zoology

Invertebrate zoology is the subdiscipline of zoology that consists of the study of invertebrates, animals without a backbone (a structure which is found only in fish, amphibians, reptiles, birds and mammals.) . Single-celled organisms or protists are usually not included within the same group as invertebrates. Invertebrates represent 97% of all named animal species, and because of that fact, this subdivision of zoology has many further subdivisions. These divisions are sometimes further divided into more specific specialties. For example, within arachnology, acarology is the study of mites and ticks; within entomology, lepidoptery is the study of butterflies and moths, myrmecology is the study of ants and so on.

Food safety

Public concerns over food safety are heightened during outbreaks of any disease in food-producing animals. Others may carry a potential risk of foodborne transmission, but their impact on human health can be minimised through a combination of animal health control measures and food hygiene practices.Jan 1, 2006. Unsafe food containing harmful bacteria, viruses, parasites or chemical substances, causes more than 200 diseases. Diarrhoeal diseases are the most common illnesses resulting from the consumption of contaminated food, causing 550 million people to fall ill and 230 000 deaths every year. Safe food is often taken for granted. However, foodborne diseases (FBD) which encompass a wide spectrum of illnesses are a growing public health problem worldwide, especially amongst the very young and very old. A staggering number of the human population falls ill as a result of ingestion of foodstuffs contaminated with bacteria, viruses or parasites.

Ethology

Ethology is the scientific and objective study of animal behaviour, usually with a focus on behaviour under natural conditions, and viewing behaviour as an evolutionarily adaptive trait. Behaviourism as a term also describes the scientific and objective study of animal behaviour, usually referring to measured responses to stimuli or to trained behavioural responses in a laboratory context, without a particular emphasis on evolutionary adaptivity Throughout history, different naturalists have studied aspects of animal behavior. Ethology is a rapidly growing field. Since the dawn of the 21st century researchers have re-examined and reached new conclusions in many aspects of animal communication, emotions, culture, learning and sexuality that the scientific community long thought it understood. New fields, such as neuroethology, have developed.

Internal Medicine Specialists

Internal medicine specialists (internists) are specialized in the diagnosis and treatment of diseases of the intestinal and urinary tract, liver, pancreas, kidneys, lungs, blood, endocrine and respiratory systems, as well as immune-mediated and infectious diseases. Your primary care veterinarian may refer you to an internist if your pet has complex issues, if a definitive diagnosis is elusive, or if he/she is not responding to standard therapies. Importantly, internists serve as an extension of your primary veterinarian’s practice, providing access to sophisticated diagnostic modalities and unparalleled resources for treatment, including other specialists when necessary.
