Developments in the field of Animal Nutrition

Even though many consumers feel uncomfortable with the idea of intensive animal production, there is no alternative way of increasing efficiency in animal husbandry and feeding. Keeping the digestive tract healthy plays a crucial role in efficient feeding of productive livestock. As an interface to the outside world, the digestive system must on the one hand transfer nutrients efficiently into the body, and on the other hand through immune system functions keep pathogenic germs within harmless limits. The fact that first of all sound feed is indispensable for this is self-evident.

» Feed additives can reduce antibiotic resistances in pigs
Minimising resitance’s reservoir

Antibiotic-resistant bacteria in pig farms cause a variety of problems in pig production. For this reason, reducing resistances to antibiotics on site is a priority objective for modern farms. Fewer resistant bacteria in the gut also mean a reduced likelihood of the genes responsible for resistance being transmitted to other bacteria, including pathogens. The result is that individual diseased animals respond to treatment and illnesses can be contained before they affect the entire herd.

» Nitrates Directive 2015
Evaluation criteria and expectations

Is the hysteria about nitrates really justified or are non-comparable survey methods causing complete disarray and misleading decision-makers, farmers and consumers? It is a fact that the discharge of nitrogen into the environment in the EU has decreased significantly over the past 35 years. Despite this, the EU Commission is calling for even more efficient application of nutrients containing nitrates in order to sustainably cut the discharge of nutrients into the environment. Once again, farmers are being used as scapegoats, although it can be shown that nitrate contamination in the environment due to animal producers has decreased considerably.

» Applying the HACCP concept in silage management
Saving silage’s quality at the critical points

What is a silage for you? Your answer will depend on your training and experience. If you are a food technologist, for example, you could define silage as “a pickled food” (for animals), or better, “a pickled vegetable preserved by lactic fermentation”, similar to a sauerkraut. In this case you will correctly look at the production of the pickled vegetable from two points of view: safety and technology ones. Obviously, for any food (or feed), the safety is the basic prerequisite, because we can’t define as “food” a somewhat unhealthy and inedible product!

» Looking back into nature
New horizons in poultry feeding

Nowadays it is very difficult to combine the consumer requirements with the interests of producers. Natural feeding and animal husbandry, the compliance of ethical aspects and especially the retention of the use of “chemical, synthetic” substances are expected on the one hand, high animal performance and efficient feeding methods are essential for an economic animal production on the other hand. The word sustainability is making the round, aims and methods seem contradictory and are not to be brought to a common denominator. Some recent data from research with natural active ingredients extracted from different plants, pure or combined, show that these two aims are not so incompatible.
