Abstract:

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 (P0.001) differences in membrane integrity between fresh vs. frozen semen samples were noticed. Pregnancy rate was significantly (P

EFFECT OF REDUCING SPERM NUMBERS PER INSEMINATION DOSE ON FERTILITY OF CRYOPRESERVED BUFFALO BULL (Bubalus bubalis) SEMEN

The objective of this study was to evaluate the effect of reducing sperm numbers per insemination dose on fertility of cryopreserved buffalo bull semen. For this purpose, semen was collected at weekly intervals from a Nili-Ravi buffalo bull (Bubalus bubalis) using an artificial vagina in two batches. The ejaculates were split-sampled and diluted at 37°C with tris-citric acid extender having 15x...

Semen 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 (%)...

Effect of Butylated Hydroxytoluene on Sperm Viability and Acrosomal Integrity in Cryopreserved Hariana Bull Semen

The present study was aimed to see the effect of butylated hydroxytoluene (BHT) as semen additives during cryopreservation of Hariana Bull semen. Twenty four ejaculates from two Hariana bulls extended with glycerolated egg yolk tris (GEYT). Extended samples were split into three aliquots. One aliquot was kept as control while other two aliquots were supplemented with 0.5 mM (T1) and 1.0 mM (T2)...

Cryocapacitation and Fertility of Cryopreserved Semen

Cryopreservation of semen is the most widely applied reproductive biotechnological tool used for rapid genetic improvement of livestock through artificial insemination, but the process of cryopreservation and thawing inflicts certain damage to spermatozoa plasma membrane and acrosome. This damage includes swelling and breakage of plasma membrane, loss of membrane selective permeability, change ...

Effect of Antibiotics in Extender on Fertility of Liquid Buffalo Bull Semen

This study was carried out to determine if a new antibiotic combination comprising of gentamycin, tylosin and linco-spectin (GTLS) in extender is suitable for improvement in fertility of liquid buffalo bull semen through artificial insemination (AI). Two consecutive ejaculates per week (4 weeks) were collected from three Nili-Ravi buffalo bulls of known fertility by using artificial vagina (42°...
