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.

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...

Ways Biotechnology Is Used In Agriculture To Make It More Sustainable

  How is biotechnology used in Agriculture Biotechnology is a science that deals with the alteration of living organisms to serve human beings. Biotechnology has been used for centuries, but it wasn't until the twentieth century that biotechnology began to truly revolutionize human civilization. The discovery of genes, their structures and functions provided new tools for scientists. It allowed them to go beyond mere manipulation or modification of crops at a superficial level into an examination of their very essence. Some of the biotechnology products include crop protection, plant breeding, and genetically modified crops. Biotechnology is used to help increase the productivity of agricultural systems while also protecting the environment. Biotechnology in Agriculture Biotechnology is a fairly new industry, and it's growing every day. There are countless areas where biotechnology can be used to help improve agriculture. For example, using pest control products is essential ...

HEALTH BENEFITS OF SLEEPING WITHOUT LIGHT.

 While asleep in the dark, the brain cells are able to rejuvenate back to their original state ( cells that were damaged due to excessive sunlight and electricity) and function properly. A study shows that Intelligent people all over the world do not sleep at night with lights on. Take note.  Sleeping in the dark or without light at night helps the body to fight Insomnia (check the meaning) Melatonin decreases in the daytime due to the presence of sunlight. Hence you should not allow light at night when the body is ready to produce it again.  Melatonin tells us it's time to sleep. Lack of it causes sleeplessness.  Sleeping without light at night makes an individual look fresh, lives longer and looks younger all the time. (Healthy). Learn to sleep at night without light for your good. Nothing bad happens to those who practice it. Don’t be scared.

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...
