Technology, Special Feed


»60 years of tailwind for the feed industry
From the former “hole in the die” to the digital twin of the production plant

Under the headline: “Progress in Feed Technology” (Kraftfutter, 1964), the successful development of the Internationale Forschungsgemeinschaft Futtermitteltechnik (IFF) e. V. was reported almost 60 years ago. In its founding phase in 1961, 34 machine factories from the Netherlands, Denmark, Switzerland, England and Germany as well as eight feed associations from Austria, Netherlands, Switzerland and Germany formed the core of the very broad-based association with more than 90 members today.

»European compound feed logistics in transition
Focus resources on the essentials

Producing high-quality compound feed is one thing. Transporting the compound feed reliably to the farms is another. Of course, producers want to be able to deliver whenever their customers want it. This means adapting the size of the fleet and driver personnel to be able to deliver at peak times. It may also mean that vehicles and drivers are idle at times when demand is lower.

»Insects as feed of the future
New technical approach

The industrial cultivation of insects as animal feed could contribute to feeding the world in the future. Bühler Insect Technology Solutions (BITS) and Alfa Laval are working together to provide solutions for specific tasks such as protein and lipid extraction, as well as complete systems including insect breeding and processing.

»Hydrothermal monocomponent Treatment
Changing demands on the feed industry: the influence of soybeans

One of the best-known machines besides the flat die press from KAHL is the expander. Its use in feed production provides numerous advantages, from hygienisation to improved pellet quality. Especially in the treatment of mono-components such as soya, the advantages of using an expander and the associated hydrothermal treatment become apparent.

»Reducing soya bean meal usage in poultry diets
Importance of a protease and xylanase combination on top of phytase in poultry diets

Poultry industry has been hit hard recently with increasing raw materials costs, reduced finished product prices (euros/kg meat or per dozen eggs) related to Covid-19 restriction at retail and catering industry. Quality of raw material varies and so does the price. Regular analysis of the raw material for crude protein, fats, and starch can help to monitor quality of raw materials and their undigestible fractions/nutrients. Chickens may need some external support to digest these undigestible fractions.

»Acting naturally against gram-positive bacteria in pigs
Improve gut health and reduce antibiotic use with targeted combinations of medium-chain fatty acids

Medium-chain fatty acids (MCFA) and their derivatives are known for their pronounced antibacterial effects against gram-positive bacteria. However, synergistic effects can only be achieved through a targeted combination of the active substances. This is also proven by a current trial on a sow farm and an in vitro study in which the influence of different MCFA on the growth of pig-specific pathogenic germs was investigated.

»Yeast Hydrolysate for protein supply
Application of GroPro in piglet diet

In the entire breeding process of pigs, the growth and development of weaned piglets is the most important. Weaned piglets grow very fast and have fast metabolism, but the digestive system is not well developed, gastric acid secretion is insufficient, digestive enzyme secretion is insufficient, and activity is low.

»More nature to life
Feed, Health and Performance

The Italian company Saviolife manufactures and proposes a natural chestnut extract rich in tannins: Saviotan® Feed. Located in Viadana (Mantua), on the banks of the river Po in northern Italy, Saviolife was created in January 2019 as a branch of the Saviola Group, headed by Alessandro Saviola, son of the founder Mauro Saviola and President of the Group. Saviolife inherited the Eco-Ethical vision of the mother company that made sustainability, environmental-friendly products and circular economy its guiding light for over sixty years.

»Use of a natural betaine source
The advantages in today's compound feed production
Globally, modern livestock production is challenged by antimicrobial resis<code_hh>tance and gut health related problems, shortages in protein supply, the impact on the environment, and consumer expectations. Consequently, the feed industry must find ways to maximize feeding efficiency that meets species-specific needs, increases production efficiency of animal sourced products, and reduces the output of environmentally relevant emissions.

»Probiotic for pig fattening
Cost efficiency is in demand
The practical use of probiotics in animal feed gained more attention over the last couple of years, due to the beneficial role on farm animals’ production and health. Also in feed for fattening pigs, where cost price plays a major role, an investment with a probiotic might be worthwhile from economic and animal health point of view.

»Balancing low crude protein diets
Histidine as next limiting amino acid in Swine

Growing concerns about the environmental impacts of animal production is an important driver for low crude protein (CP) strategies in modern fattening practices. Reducing the nitrogen (N) intake have a significant effect on N excretion and consequently on the environmental N load. On average, each 1% decrease in crude protein (CP) lead to a reduction of nearly 2.8 % N excretion (Wang et al. 2018). Additionally, high protein intake lead to protein fermentation in the hindgut and is especially in weaning piglets associated with gastrointestinal disorders like post-weaning diarrhoea (Nyachoti et al 2006, Wellock et al 2008). In cereal based diets, histidine may become next limiting after valine and isoleucine.
