  1. 11. Sow and piglet behaviour and weight: implications of different ages of weaning : a study within Swedish piglet production

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Rebecka Brattlund Hellgren; [2021]
    Keywords : piglet; sow; weaning age; behaviour; growth;

    Abstract : Natural weaning of piglets occurs gradually and finalises between 14-17 weeks of age. In 2017, Swedish pig production faced changes in national regulations regarding weaning procedures. The new regulations implemented a decrease of weaning age from 28 days of age to 21 days of age for a maximum of 10 % of piglets in each batch. READ MORE

  3. 12. The effect of forage on piglets’ behavior in connection with weaning

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

    Author : Linnea Wikars; [2021]
    Keywords : behaviour; enrichment; forage; pig; silage; weaning;

    Abstract : Pigs’ (Sus scrofa) behaviors are affected by the environment they are housed in, where an enriched environment offers pigs to perform more diverse behaviors. Pigs reared in barren environments perform more oral manipulation toward their pen mates, compared to pigs reared in enriched environments. READ MORE

  4. 13. Lying behaviour of lactating dairy cows in a cow-calf contact system

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

    Author : Claire Sydney Wegner; [2021]
    Keywords : cow-calf contact system; dairy cattle; lying behaviour; welfare;

    Abstract : Conventional dairy farming practices usually involve the early separation of calves from their dams. Cow-calf contact (CCC) systems may offer an alternative rearing solution that allows for the expression of natural behaviours, such as suckling and bonding. READ MORE

  5. 14. I like to move (it) - Use of outdoor space in a mixed exhibit of ring-tailed lemurs (Lemur catta) and red ruffed lemurs (Varecia rubra) at Furuvik Zoo

    University essay from Linköpings universitet/Biologi

    Author : Gabriel Aritz Robinson González; [2021]
    Keywords : ring-tailed lemurs Lemur catta ; red ruffed lemurs Varecia rubra ; zoo mixed-exhibit; use of outdoor enclosure; lemur behavior; environmental enrichment;

    Abstract : By studying how captive animals use outdoor space, we can determine which areas fulfill their biological and behavioral needs to improve enclosure design for animal welfare and visitor experience. The aim of the study was to determine the differential use of outdoor space in a mixed exhibit of captive ring-tailed lemurs (Lemur catta) and red ruffed lemurs (Varecia rubra), and to assess both the effect of adding environmental enrichment and possible visitor and meteorological effects on the lemurs’ use of space and behavior.

  6. 15. The effect of feeder space on pig behaviour and performance in organic production with a pig sort feeding system

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Karolína Steinerová; [2020]
    Keywords : agonistic interactions; feeding; feeding place; performance; organic production; behaviour; pig;

    Abstract : Behaviour at feeding and performance of pigs can be influenced by the design of the feeding area. Resources allocated in restricted space cause a disruption in communicative behaviour and even pigs in established hierarchies compete for feed. Therefore, a substantial amount of agonistic behaviour happens at feeders. READ MORE
