  1. 1. Effects of silage and haylage on feed intake, growth and health in two meat type chicken genotypes

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Temwanoku Ioakim; [2018]
    Nyckelord :silage; haylage; broiler hybrid; feed intake; growth; health;

    Sammanfattning : In this project the effect of grass silage and haylage on feed intake (FI), growth and health of two meat type chicken hybrids, Ross 308 and Rowan Ranger were studied. The study was carried out at the Swedish Livestock Research Center, located in Funbo-Lövsta, Uppsala for a period of 42 days. LÄS MER

  3. 2. Texturskillnad i kyckling : påverkar ett tillskott av morötter och grönkål i fodret de sensoriska egenskaperna hos kyckling?

    Kandidat-uppsats, Högskolan Kristianstad/Fakulteten för naturvetenskap

    Författare :Dawid Alwan; Patrik Johansson; [2018]
    Nyckelord :Carrot- and kale chicken; Ross Rowan Ranger; duo-trio test; two paired sample test; Morots- och grönkålskyckling; Ross Rowan Ranger; duo-triotest och partest;

    Sammanfattning : Introduktion: Att påverka de sensoriska egenskaperna hos kyckling genom att anpassa fodret kycklingarna får vid uppfödningen, är ett intressant koncept som kan leda till många möjligheter. På Bosarps gård utanför Blentarp i Skåne har man arbetat med ett sådant koncept genom att tillföra morötter och grönkål som ett komplement till basfodret. LÄS MER

  4. 3. Perching behaviour and disturbance during sleep in three hybrids of broiler chicken (Gallus gallus domesticus)

    Kandidat-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Maja Wedin; [2016]
    Nyckelord :broiler chicken; perching; sleeping behaviour; welfare; hybrids; organic production;

    Sammanfattning : The aim of broiler chicken production is to breed chickens with high growth rate and muscle/bone ratio. However, this selection has affected the physiology of the broilers and as a result broilers display a physique that inhibits them in executing behaviours that they are motivated to perform. LÄS MER

  5. 4. Comparison of behaviour and health of two broiler hybrids with different growth rates

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Sofia Wilhelmsson; [2016]
    Nyckelord :Broiler; chicken; welfare; health; behaviour; gait; fear; perching; dustbathing;

    Sammanfattning : Until recently fast growing broiler hybrids have been used exclusively in both conventional and organic broiler production in Sweden. This study aimed to quantify differences in behaviour and health between a fast growing hybrid (Ross 308) and a slower growing hybrid (Rowan Ranger). LÄS MER

  7. 5. Effects on domestication and feeding on the avian melanocortin system

    Kandidat-uppsats, Linköpings universitet/Biologi

    Författare :Malin Jonsson; [2016]
    Nyckelord :Feed-restriction; hunger; arcuate nucleus; gene expression; avian melanocortin system; domestication; broiler; Red Junglefowl; stress;

    Sammanfattning : Domestication in chickens has made feed-restriction a necessity if broiler breeder hens should reach sexual maturity and be fertile. This is claimed to cause chronic hunger. LÄS MER
