1. 6. Effect of freezing and thawing rates on camel sperm quality

   University essay from SLU/Dept. of Clinical Sciences

   Author : Bodil Elwing; [2017]
   Keywords : Camel semen; cryopreservation; freezing rate; thawing temperature; motility analysis;

   Abstract : The objective of this study was to evaluate the effect of different freezing rates and thawing temperatures on the quality of camel spermatozoa post thawing. Ten ejaculates from five male camels were frozen at five different freezing rates, achieved by placing the straws at specific heights above the surface of liquid nitrogen for different times (4 cm for 15 min; 1 cm for 15 min; 7 cm for 15 min; 7 cm for 5 min + 4 cm for 3 min; 4 cm for 5 min + 1 cm for 3 min) followed by storage in liquid nitrogen.

   Keywords : spermafrysning; hundsperma; sojalecithin; äggula; cryopreservation; canine semen; soybean lecithin; egg yolk;

   Abstract : Fryst eller kyld sperma används ofta vid artificiell insemination på hund. Skador kan uppstå på spermierna under frysningsprocessen. För att spermierna ska bibehålla sin viabilitet och undvika skador tillsätts spädningsvätskor som bland annat innehåller sockerarter, antibiotika, glycerol och äggula. READ MORE

5. 9. Livslängden hos kyllagrade spermier vid artificiell insemination hos häst - kan den förlängas?

6. 10. Analys av dräktighets- och fölningsresultat inom svensk varmblodig ridhäst och svensk varmblodig travhäst åren 2000-2006

   University essay from SLU/Dept. of Animal Breeding and Genetics

   Author : Karolina Johansson; [2010]
   Keywords : häst; fertilitet; svensk varmblodig ridhäst; svensk varmblodig travhäst; dräktighet; fölningsresultat;

   Abstract : The purpose of this thesis was to analyze conception and foaling results of Swedish warmblood and Standardbred trotters using breeding statistics during the years 2000-2006. Key issues in this thesis were: Have the conception and foaling results of stallions changed during the period 2000-2006? What is the effect of the use of various breeding methods? Is testicle size correlated with conception and foaling results? How important are age, breed and level of inbreeding of the stallion for conception and foaling results? Breeding statistics were available for 537 Swedish Warmblood stallions and 305 Standardbred trotter stallions. READ MORE
