THE SIGNIFICANT ROLES OF ANIMAL BREEDING IN THE DEVELOPMENT OF ANIMAL AGRICULTURE

Animal breeding, genetics, and genomics is the branch of science concerned with maximizing desirable genetic traits, such as producing animals that have leaner meat. Animal geneticists have identified elements within genes that can enhance animal growth, health, and ability to utilize nutrients. These genetic advances can increase production while reducing environmental impacts.



IMPORTANCE OF ANIMAL HUSBANDING
Animals and farm animals contribute 40 percent of the world value of agricultural production and contribute to the livelihood and food security of almost a billion people worldwide. Advances in animal husbandry, genetics, and genomics make the industry more efficient. For example, livestock has declined over the past decade, but overall meat and milk production has increased. This was mainly possible because genetic advances resulted in better feed efficiency (link is external), which is critical to improving livestock production and reducing costs for producers.

Services of livestock:
Livestock provides people with a variety of products and services, including meat, milk, eggs, fiber, and traction, in a variety of settings. This diversity of functions is only possible because of the diversity of their genetic makeup.

Genetic variation :
Genetic variation within livestock populations also provides the raw material both for evolution through natural selection in response to changing conditions and for human-controlled breeding programs. such as climate change, emerging diseases, and pressures on food and water resources.



Animal genetics:
Animal genetics is one of the pillars of farm animal development (together with animal health, animal nutrition, and the rearing of animals such as stables). It is a broad field, ranging from characterization to conservation to genetic improvement and encompassing measures at local, national, regional and global levels.



Characterization:
Characterization involves assessing livestock populations and their production environments to determine their current status and identify strengths that can be improved and weaknesses that need to be overcome, for example, through a genetic improvement program. It can also help educate conservation strategies.



Conservation of animal genetic resource:
Conservation of animal genetic resources refers to measures that are taken to prevent the loss of genetic diversity in livestock populations, including protecting breeds from extinction. This can be both the preservation of living populations and the cryopreservation (preservation by freezing at extremely low temperatures) of material such as seeds or embryos.

Genetic improvement:
Genetic improvement (animal husbandry) is based on the principle that products (milk, meat, wool etc.) and services (e.g. transport, traction or cultural services) of animals are a function of their genes and the environment. Influences to which they are exposed. Improvement can be achieved by selecting genetically superior animals as parents of the next generation. “Genetically superior” means superior in relation to a certain set of traits, which generally include productivity under expected environmental conditions in the future. But it must also consider traits such as fertility, disease resistance, or longevity, which are related to production costs.



Since the mid-20th century, genetic improvement efforts have focused on a very small number of breeds around the world, often without considering how local production environments affect the animals' ability to survive, too, produce and reproduce.

Allergy|| What is Allergy

                                What is Allergy? Allergies are your body’s reaction to an ordinarily harmless substance resembling pollen, molds, animal dander, latex, certain foods and bug stings. An allergic reaction symptoms vary from mild – rash or hives, itchiness, fluid nose, watery/red eyes – to life-threatening. Treatments embrace antihistamines, decongestants, nasal steroids, asthma attack medicines and immunotherapy. What are allergies? Allergies are your body’s reaction to a substance it views as a harmful “invader.” For example , returning into contact with what's normally a harmless substance, such as pollen, may cause your system (your body’s defense system) to react. Substances that cause these reactions are referred to as allergic agents. What's associate allergic reaction? The associate “allergic reaction” is the approach your body responds to the allergen. A sequence of events that occur t...

IMPORTANCE OF PLAYING SPORTS AND GAMES IN SCHOOL

  Sports and games serve a variety of important purposes in school. These include helping children learn responsibility, building social skills, and coping with stress. When students engage in sports and games they also improve their overall academic performance. This is because activities such as sports help to build mental resilience that creates the foundation for lifelong success through multitasking skills which are learned throughout participation. These skills are important not only in sports but also in all aspects of life. In addition, athletics provide a developmental boost to the body. In fact, playing sports helps children develop physically and mentally. In the classroom, sports and games help students learn teamwork and build social skills. The classroom can be an intimidating place for new students who have not yet established relationships with their peers. Students who participate in games and sports at school tend to develop strong peer relationships that serve as...

BRIEF PARAGRAPHS ON SUGAR BEET

  A sugar beet is a plant that is grown commercially for sugar production and has a high concentration of sucrose in its root. The Altissima cultiva group of the common beet is known in plant breeding (Betavulgaris). It belongs to the subspecies Beta vulgaris subsp. Vulgaris, along with other beet cultivars like beetroot and chard. The sea beet is its closest wild relative (Beta vulgaris subsp. Maritima). The sugar beet has a flat crown and a conical, white, fleshy root (a taproot). The root and a rosette of leaves make up the plant. Photosynthesis produces sugar in the leaves, which is ultimately stored in the root. The beet root is 75 percent water, 20 percent sugar (or 18 percent sugar), and 5 percent pulp. Depending on the cultivar and growth conditions, the sugar concentration might range from 12 percent to 21 percent. Sugar beet is primarily used as a commercial crop because of its high sugar content. Animal feed is made from the pulp, which is insoluble in water and mostly m...

Plastic and Its Effect on Our Health

  Now a day use of plastic is on its peek. We wrap things in plastic wrap. We use plastic bags for a variety of things.Plastic is everywhere. Plastic protects our phones, books, and important papers. Plastic lines the insides of canned food to protect them. Effect  Plastic  on Our Health:  D isrupt our hormones: Plastic has many useful uses not only for our homes but also for important industries. This can cause some of the molecules to break down. All of our exposure to so much plastic is starting to disrupt our hormones.  Excessive "xenoestrogenic": Many types of plastic have excessive "xenoestrogenic" effects. Once we get too much into our bodies, we can begin to notice hormonal imbalances in women and men that seem like too much estrogen.  This can have many negative effects, particularly on fertility, menstruation, growth and development, and overall health and wellbeing. Xenoestrogens disrupt our normal endocrine system and have been linked to breast ...
