| description | No summary of feeding recommendations for foals exists today, which is why this subject was chosen for a literature study. The aim of this study was to describe nutrient requirements of healthy full term foals and how the feeding should be designed to raise foals if they lose their mother. Mare milk composition changes during lactation to meet the requirements of the suckling foal. Foals are born with enzymes in their small intestine and the concentrations of these follow the consumption patterns of the foal. Microbes colonizes the gut as the foal becomes older and these changes cause foal diarrhea. Foals are born with a digestive tract incapable for digestion of grass but the large intestine grows and develops for a long period of time which gives the foal a higher capacity to digest fiber the older it gets, partly stimulated by growth factors in the mare milk. Orphan foals shows a temporarily lower growth after weaning but thereafter undergoes a compensatory growth. By looking at the nutritional values in mare milk the nutrient requirements of foals could be estimated and compared to three commercial milk replacers and cow’s milk with 1,5 % fat. |

Eftersom det idag saknas en sammanställning av utfodringsrekommendationer för föl valdes detta som ämne för denna litteraturstudie. Syftet var att undersöka vad friska fullgångna föl har för näringsbehov och hur utfodringen ska utformas för att föda upp föl ifall de förlorar sin moder. Stomjölk genomgår en mängd förändringar i komposition under laktationen och föl får sina näringsbehov uppfyllda när de diar sina mödrar. I tarmkanalen finns enzymer vars halter följer konsumtionsmönstret hos föl och mikrober koloniserar tarmen i takt med åldern på föl vilket orsakar földiarré. Föl föds med en tarmkanal som inte är fysiologiskt anpassad till konsumtion av gräs men näringsutnyttjandet av grovfoder ökar i takt med att grovtarmen växer, och stomjölk innehåller tillväxtfaktorer som kan inducera sådan tillväxt av tarmkanalen. Moderlösa föl har en temporärt lägre tillväxt efter avvänjningen från modern men genomgår en kompensatorisk tillväxt. Genom att titta på näringsinnehåll i stomjölk kunde näringsbehov hos föl uppskattas och jämföras med tre kommersiella mjölkersättningar och mellanmjölk. 2015-07-02 First cycle, G2E NonPeerReviewed application/pdf sv https://stud.epsilon.slu.se/8219/7/klasson_p_150702.pdf Klasson, Pauline, 2015.
