Nowadays, probiotics are commonly used to increase livestock productivity. The use of probiotics is increasingly being studied. Probiotic is a term for living microorganisms that can have good effects. These microorganisms are good for the health of other organisms and their hosts. Bacteria that are not pathogenic to livestock or humans are a characteristic of probiotics. Bacteria must be normal microorganisms that are in the digestive tract. Bacteria must also be able to carry out colonization in the intestine, must be resistant to stomach acids, bile acids and salts, digestive enzymes, and responses in the body of livestock. Finally, bacteria must be able to produce broad-spectrum antibacterial agents in pathogenic bacteria in the human digestive tract.

The use of probiotics for alternative feed additives is more beneficial than the use of antibiotics. The use of antibiotics as a growth booster is also known to have several negative effects on animal health and its production results. Provision of antibiotics in livestock in the long term can cause livestock to be immune to pathogenic bacteria. Meanwhile, the use of probiotics as feed additives is more friendly to human welfare, livestock, and the environment.

The mechanism of action of probiotics in the digestive tract is to colonize the intestine, so that it can be modified for the immune system / immunity of host animals. The ability to stick to strong intestinal cells will cause probiotic microbes to develop properly and pathogenic microbes are reduced from host animal cells. This causes the development of pathogenic organisms that cause the disease, such as E. coli, S. Thyphimurium in the digestive tract will be inhibited. There are several factors that affect the performance of probiotics such as the composition of the host microbiota, how to administer probiotics, and the quality and type of probiotics used.

In ruminants with low-quality feed character, high cellulolytic microorganisms are needed to utilize forage or agricultural waste as efficiently as possible in producing the nutrients needed by livestock. The existence of probiotics which are feed additives containing live microorganisms that benefit the host can improve the balance of microorganisms in the digestive tract. Likewise, in non-ruminant animals, the use of probiotics can prevent the growth of bacteria or organisms that are harmful to the host. This use can also increase the digestibility and absorption of feed nutrients. Also, the provision of sufficient quantities of probiotics can affect the composition and ecosystem of the digestive microflora. The condition of the microflora ecosystem in a balanced digestive tract in monogastric animals will be able to influence the performance and health of livestock.

So, the benefits of adding probiotics to animal feed are highly recommended because the use of probiotics in animal feed is more friendly to human welfare, livestock, and the environment because livestock can prevent metabolic disorders, reduce methane gas production, and stimulate the immune system. The advantage for farmers, probiotics are more easily produced, cheaper, and easily obtained.
