Sperm Characteristics in Cryopreserved Buffalo Bull Semen and Field Fertility
Semen quality and its relationship to fertility are major concern in animal production. The aim of this study was to assess the relationship between frozen thawed sperm characteristics and fertility following in vivo fertility through Artificial Insemination(AI). Semen samples were collected from four buffalo bulls. Semen volume and sperm concentration appeared to be significantly different (P0...
متن کاملHigh dilution rate of bull semen affects cryopreservation outcomes: kinematic and flowcytometric parameters
BACKGROUND: Semen cryopreservation might be influenced by sperm concentration. OBJECTIVES: This study was conducted to investigate three different semen concentrations [100 (C100), 50 (C50), and 25 (C25) × 106 spermatozoa/mL] on freezability of bull semen. METHODS: On each collection day, four ejaculates were collected (a total of 24 ejaculates from four bulls), pooled and divided to three equ...
متن کاملSemen Ejaculates Characteristics, in vitro Fertility and Their Interrelationships in Sahiwal Bull Semen
This study aimed at determining the physico-morphological attributes, in vitrofertilityand their interrelationships in semen of Sahiwal bulls. Semen samples werecollected weekly for 6 weeks from ten mature Sahiwal bulls divided randomly into 5 groups. The mean (±SEM) of ejaculate volume (mL), mass activity (score 0-5), progressive sperm motility (%), sperm concentration (106/mL), live sperm (%)...
متن کاملFertility of Bull Semen Frozen in Skim Milk Diluent
In Victoria the usual diluent for deep frozen bull semen consists of a mixture of egg yolk, sodium citrate and glycerol. The semen is equilibrated in this mixture for 17 hours prior to freezing. O’Dell and Almquist (1957), and Amman and Almquist (1957) found that survival of spermatozoa as assessed by motility was increased when the semen was diluted with a mixture of glycerol, fructose and ski...
