Micro-Organisms as Feed Additives – Probiotics

For many decades antibiotics (so called growth promoters) have been used as feed additives in various species of farm animals, to reduce the frequency of diarrhoea under certain conditions. Furthermore, in most cases performance parameters like body weight gain or feed conversion ratio improves to up to 5%. These beneficial effects of feed antibiotics are generally explained by modifications of...

BIOFUEL CO-PRODUCTS AS LIVESTOCK FEED Opportunities and challenges

Feed additives.

Feed additives used to supplement dairy rations can increase daily feed cost from 2 to 65 per animal. The economic response (benefit to cost ratio) varies from $2.00 to $12.00 for each dollar invested in a specific additive. Knowledgeable dairy veterinarians must understand the role of each additive, when it will be beneficial, inclusion level, strategies and limitations associated with an addi...

Use of 'natural' products as alternatives to antibiotic feed additives in ruminant production.

The banning in 2006 of the use of antibiotics as animal growth promoters in the European Union has increased demand from producers for alternative feed additives that can be used to improve animal production. This review gives an overview of the most common non-antibiotic feed additives already being used or that could potentially be used in ruminant nutrition. Probiotics, dicarboxylic acids, e...

The importance of using microbial feed additives in breeding ornamental fish

In line with the growth of the aquaculture industry, the reproduction and cultivation of ornamental fish has developed significantly due to its high economic importance. One of the most important challenges in the aquaculture industry is the improvement of formulated diets to improve the growth efficiency, nutrition and immunity of fish. In recent years, many efforts have been made in connectio...
