- Reduced ammonia volatilization in poultry production by adjusted feed composition The aim of the suggested project is to evaluate if ammonia volatilization from the litter in laying hen facilities can be lowered by adjusted levels of crude protein, amino acids and insoluble fibre in the feed.
- Improved animal welfare with lower ammonia in poultry houses The aim of the project is to evaluate alternative litter materials and feed compositions as strategies to reduce ammonia levels in poultry houses.
- Feeding live insect larvae to laying hens This project aims to investigate the potential use of live soldier fly larvae (Hermetia illucens) as a novel environmental enrichment to promote food foraging behaviours and reduce feather pecking in laying hens. A secondary aim, is to utilize fly larvae, grown in Sweden using local organic blue mussel by-products, as an alternative food source for poultry to reduce reliance on imported proteins (such as soy).
- Mother knows best; a virtual system of ‘maternal care’ to promote welfare in chickens This project aims to develop a virtual system of maternal care using video and audio signals to improve the naturalness of rearing conditions of newly hatched chicks and promote natural behaviours, behavioural synchronisation, reducing fearfulness and feather pecking in laying hens.
- Adapted management and feeding strategies for improved chick quality Including bioactive substances from brown algae or fungi biomass in chickens first feed will be evaluated in this project. The broiler chickens will either get access to feed and water already from time of hatch, or have to wait for a period corresponding to the normal situation in commercial settings.
- Brown algae to broiler chickens With an increasing world population and food consumption, poultry is predicted to be the most common meat source globally in 2020. However, to be able to meet the increasing demand in a sustainable way all parts of poultry meat production needs to be optimized. A way to accomplish this could be by the use of feed additives with bioactive substances. A bioactive substance promotes health and gives additional value to the diet. Brown algae has a higher content of bioactive substances than many other algae and plants and are therefore of interest to evaluate as feed additive to broiler chickens.
- Why transport the newly hatched chick when it can travel safe inside the egg? The aim of this project is to study effects of different hatching concepts and feed additives on the day old chicks’ quality, gut microflora and immune system.
- Campylobacter in broilers Is a reduction of campylobacter possible by feeding silage?
- Welfare indicators in laying hens The goal with this project was to increase the understanding and knowledge about different ways of measuring welfare of laying hens.
- Increased use of rape seeds and faba beans in broiler chicken diets Heat treatment in the form of steam-pelleting allows inclusion of more rape seed and white flowered faba beans in broiler chicken feeds.
- Selectable markers for improved welfare in Swedish Laying hens This project will identify genomic regions affection bone strength in egglaying chicken (layers) and assess their potential welfare benefits in different environments.
