In the field of animal husbandry, biotechnology is used to produce antibodies, highly nutritious feed, vaccines, and growth hormones. Examples of vaccines for livestock one of them is a vaccine for foot and mouth disease in mammals. NCD as well as vaccines for Newcastle disease in poultry cure and a vaccine for avian flu (H5N1).
Growth hormones given to livestock aims to increase the production of milk, meat, or eggs. Examples such as Bovine Growth Hormone administration to dairy cows to increase milk and meat production amount to 20%. However, the use of hormones to increase production in cattle is still debated. because in this way has the potential to improve disease mastitis in cattle and can be harmful to human health.

Utilization of biotechnology in animal husbandry is making transgenic animal technology and artificial mains. Artificial stem technology is often performed on endangered animals that are difficult to reproduce naturally. The workings of GMOs are transplanted embryos were animals in the womb of other animal species are still closely. In this way is expected to animals that are difficult to reproduce can avoid extinction. Below I will discuss some of the application of the principles of biotechnology in livestock.
Example 5 Biotechnology Ranch
- Technology nucleus transplant
nucleus transplant technology is known as cloning technology. transplant cloning is a technology used to obtain individual results in duplicate or similar to its parent. Cloning technology has been successfully performed on several species of animals. One example was the cloning of sheep known as Dolly the sheep. Through the cloning of animals, some organs of the human body for the purposes of transplantation cure a disease also successfully established.
- Techniques Artificial Insemination
Artificial Insemination Techniques in society often called mating injection. Artificial insemination technique is a technique or a way to insert sperm derived from male animals that have been thawed and processed first into the female genital tract by using methods and a special instrument called insemination gun. Artificial insemination technique has several objectives as follows:
- Improving the quality of genetics in cattle
- Optimizing the superior male seed is greater in a longer period of time
- Increase the number of births to quickly and regularly
- Preventing the spread and transmission of venereal diseases.
- Embryo Transfer
Embryos transversion is almost the same as the mating injection. If the mating syringe focus on the male sperm, the embryo transfer is not only focused on the potential of the male sperm are optimized embryo transfer was also focused on the potential of the female superior quality and optimally utilized.
TE abbreviated technique has sophisticated techniques. Females excel not need to be pregnant but merely serves to produce embryos to then be transferred to the parent entrusted with the quality that does not need to be great but has the ability to get pregnant.
Embryos to be inserted into a recipient stored in the Foley catheter two lanes sterile (depending on the size of the cervix). Prior to harvest embryos, parts of the vulva and vagina should be clean and sanitized by using a cotton containing 70% alcohol. The resulting embryos can be directly sent to the recipient cows can even be frozen and stored if you want to transfer at another time.
- Transgenic Technology
Transgenic technology is technology performed on animals that have undergone genetic engineering so that the animals can be produced with properties that are expected. Transgenic animal technology is done by editing the DNA fragment at the micro into an egg that has been fertilized. The purpose of this transgenic technology is increasing the productivity of farm animals such as meat, milk, and eggs.
. hormone BST (Bovine Somatotrophin)
With genetic engineering can produce animal growth hormones are BST. To produce it requires as follows:
- Coli bacterial plasmids cut with the enzyme endonuclease
- Gen somatotropin mammalian cells isolated from cow cow
- somatotropin gene inserted into bacterial plasmids
- Bacteria that produce bovine somatotropin grown in fermentation tanks
- Bovine somatotropin is taken from the bacteria and purified.
BST hormones can trigger growth and increase in milk production. The BST hormones controlling lactation or milk expenditure by increasing the number of cells in the mammary gland.
The use of hormone BST has been approved by the Food and Drug Administration (FDA). The FDA agency oversees drug and food duties in the United States. American believes the milk produced by hormone BST safe for consumption. But in Europe it is banned because disease mastitis in animals that were given the hormone BST have increased 70%.
In addition to increasing milk production, BST hormone can also increase the size of the animal to be 2 times the normal size. How to use by injecting eggs that will be fertilized with the hormone BST. The meat of animals resulting from BST hormones have less fat. So it is feared that this hormone can affect people’s health.
