Effect of the Addition of Insulin Like Growth Factor-I (IGF-I) on Cryopreservation of Hariana Bull Semen
This experiment was designed to study the effect of insulin like growth factor-I (IGF-I) on cryopreservation of Hariana bull semen. For this purpose, semen ejaculates were collected from four Hariana bulls using artificial vagina at biweekly interval. The semen samples which possess more than 70% initial progressive motility and above 500 million/mL spermatozoa concentration was subsequently su...
متن کاملSperm 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 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 کاملLake metabolism: Relationships with dissolved organic carbon and phosphorus
Recent literature has suggested that for many lakes and rivers, the respiratory breakdown of organic matter (R) exceeds production of organic matter by photosynthesis (gross primary production [GPP]) within the water body. This metabolic balance (GPP , R; ‘‘heterotrophy’’) implies that allochthonous organic matter supports a portion of the aquatic ecosystem’s respiration. Evidence that many lak...
