For and by our partner companies, we develop projects that contribute to the goal of achieving a sustainable animal protein chain. The focus here is on health, technology and the use of new raw materials.
Feed Design Lab participates actively in research such as the PPP Circular Bio-economy and an INTERREG NWE project dealing with the development of algae and their technological applications.

Algae and insects
Following exploratory studies, two HAS Venlo students interning at Feed Design Lab carried out a project to compare the in vitro amino acid digestion of algae and insects with that of soya meal and fish meal. The algal species Spirulina and whole Black Soldier Fly larvae were used to produce a pelleted pig feed. Other test feeds contained soya meal or fish meal.
The resulting feeds were used in an in vitro model mimicking digestion in pigs. The amino acid profile of the output was then analysed in the laboratory. Calculations were performed to determine the in vitro ileal digestion of each test material.
The results were presented to the Feed Design Lab partners.
Optimal particle size in broiler feeds
Feed Design Lab partners joint-funded a project carried out by Zetadec and Feed Design Lab. The aim was to identify the optimal particle size for corn, wheat and soya meal used as raw materials in broiler feed. A coarse and fine variant of each test material was produced. These were then used to create six combinations or “treatments” that were manufactured as pelleted trial feeds. After feeding these to broilers, the results in terms of growth, feed intake, feed conversion and litter score were calculated and processed statistically. In the presentations and final report, the measurements taken during raw material and feed production and the subsequent broiler trial were discussed and conclusions were drawn.
Use of circular co-products in livestock feeds
13 companies and knowledge centers work together in the PPS project to use in a sustainable and safe way co-products in feeds production animals. Read more
Managing on manure output in pig farming
During the first phase of the project literature study has been done by a student of the HAS University. The content of this literature study was mainly about:
- Digestion and intake of the pig;
- Analyse possibilities of manure;
- Functions of trace elements, vitamins & minerals, etc.;
- Exogenous influences on animal welfare.
A second student of the HAS University did actual fieldwork during the second phase of this project. Manure samples have been collected at two pig farms who opened up for collaboration. The manure samples are mainly collected on group level, a single one on animal level. Next the samples have been analysed by Near-InfraRed spectroscopy (NIR). NIR measures a broad scale of specific frequencies of molecules on the whole spectrum. The NIRS clearly showed differences between the two test farms and also between individual and group samples. The analysed samples showed that differences in manure can be linked to differences in animal prestations and/or health status by the use of NIR. Follow-up research after the use of monitoringssystem is advisible.
The project has been submitted at WUR who will do further research on individual animal level and refining the technology around NIR.
Optimal particle size in piglet feeds
11 partner companies within the Feed Design Lab network from 5 countries joint-funded a project on optimal particle size of raw materials used in pelleted piglet feed. The aim was to identify the optimal particle size for wheat, barley and soy bean meal used as raw materials in pelleted piglet feed. 4 treatments were tested in the weaner and rearing phase of piglets in an experimental farm.
Feed intake, growth, feed conversion ratio and faecal scores were calculated and statistically processed. In the presentations and final report, the measurements taken during raw material and feed production and the piglet trial were dicussed and conclusions were drawn.
