  1. 1. Feeding brown algae and brown algae extracts from Saccharina Latissima to Broiler breeders : effects on transfer of antibodies and nutrients from hen to egg

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Stina Kling; [2021]
    Keywords : broiler; broiler breeder; brown algae; Saccharina Latissima; laminarin; prebiotic; transfer; antibodies; nutrients; iodine; chicken; egg quality;

    Abstract : Brown algae and extracts of algae have been proved to have prebiotic effects. Seaweeds grow very fast and underwater. This is good from a sustainable point of view since algae do not need fertilizers, freshwater or agricultural land for growth. Brown algae is rich in nutrients, vitamins and minerals, and has an especially high content of iodine. READ MORE

  3. 2. Seasonal changes in clupeids maturation constrains the food quality of chicks of the common guillemot (Uria aalge) : A case study of a potential mismatch, from the perspective of the common guillemot chicks on Stora Karlsö, the Baltic Sea

  4. 3. Identifying factors of importance for chick quality and traits that may predict chick quality

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Cecilia Hjelm; [2018]
    Keywords : chick quality; chick quality score; first week mortality; broiler breeder; IgY yolk concentration; IgY serum concentration;

    Abstract : In the hatcheries today, the eggs that have cracks are sorted out before incubation. When hatched the chicks are graded as saleable or unsaleable, and salable chicks are transported to the farm. First week mortality (FWM) is a common way to assess chick quality and performance at the farm and it varies among flocks. READ MORE

  5. 4. Evaluating camera monitoring of breeding seabirds

    Author : Elida Lundgren; [2018]
    Keywords : ;

    Abstract : This thesis was made in collaboration with the Baltic Seabird Project with the purpose of evaluating the possibilities of using cameras to monitor the fledging success of Common Guillemots on Stora Karlsö. Fledging success is measured from the time the egg is laid, hatched, until the chick is 15 days old and considered ready to leave the nest. READ MORE
