Hens support calves in their critical first phase of life
By Dr. Inge Heinzl, EW Nutrition Calves are particularly susceptible to disease because ruminants have a multilayered placenta (placenta epitheliochorialis), and transplacental transfer of immunoglobulins is either absent or occurs only to a very limited extent. This means that the animals must build up their own defenses during the first weeks of life and depend […]
Fighting antimicrobial resistance with immunoglobulins
By Lea Poppe, Regional Technical Manager On-Farm Solutions Europe, and Dr. Inge Heinzl, Editor One of the ten global public health threats is antimicrobial resistance (AMR). Jim O’Neill predicted 10 million people dying from AMR annually by 2050 (O’Neill, 2016). The following article will show the causes of antimicrobial resistance and how antibodies from the […]
Cryptosporidia in calves – chickens can help
By Lea Poppe, Regional Technical Manager, EW Nutrition Diarrhea due to infestation with cryptosporidia is one of the most pressing problems in calf rearing. These protozoa, along with rotaviruses, are now considered the most common pathogens in infectious calf diarrhea. Due to their high resistance and thus limited possible control and prevention measures, they have […]
Coughing calves? How to save costs and prevent respiratory disease
By Judith Schmidt, Product Manager On Farm Solutions There will always be germs in barns. Yet, calves are particularly susceptible to lung viruses and bacteria that attack the respiratory systems. What can we do to prevent calf flu? Coughing in calves is one of the most obvious signs of illness. It should be taken seriously […]
Calf diarrhea: types, causes, solutions
By Dr. Inge Heinzl, Editor, EW Nutrition Diarrhea causes a higher workload, increased costs for treatment, losses, and, of course, lower benefits for the farmer. But not all diarrheas are equal. How do they differ, where do differences come from, and what can you do to protect your animals? Diarrhea is a protective measure of the […]
IgYs support calves in case of diarrhea
By Lea Poppe, Technical Manager – Europe, EW Nutrition Humans and animals protect themselves against diseases with specific antibodies (immunoglobulins). They receive antibodies from their mother or a vaccination (passive immunity) or produce them themselves after contact with a pathogen (active immunity). To be protected by a high passive immunity during the first weeks of life, […]
Diarrhea in calves: Causes, consequences, prevention
by Judith Schmidt, ProductManager On Farm Solutions, EW Nutrition Although diarrhea is called a factor disease, strictly speaking, it is not a disease but a symptom. Diarrhea can be a protective function of the body. With the higher fluid volume in the intestine and its increased peristalsis, pathogens and toxins are excreted. Common causes of […]
Diarrhea? Egg powder to the rescue
Another tool to reduce the use of antibiotics is the use of immunoglobulins from eggs. Trials showed that this product is effective to support a calf’s start in life and also to offer support when challenged by various forms of diarrhoea. The main cause for calf losses during the first two weeks of life is […]
