Comparative study of reproductive and estrus characteristics of sexed and conventional semen in crossbred cows under field conditions.

Background And Aim: Sexed semen (SS), a reproductive biotechnology tool, can alter the sex ratio of offspring in bovines. This study elucidates a comparative analysis of estrus-related parameters influencing conception rate and pregnancy losses under field conditions between conventional and SS.

Materials And Methods: In the present study, artificial insemination with (SS; n = 143) and conventional semen (CS; n = 143) was performed at spontaneous estrus, i.

Comprehensive exploration unveiling the sonography and histopathology of uterine leiomyoma in a cow.

Genital tumours are rare among cattle, largely due to their relatively short lifespans. Leio-myoma, a smooth muscle tumour being more prevalent in dogs, appears only at a rate of 1.00 - 2.

Additional intracervical prostaglandin reduces induction to calving time in buffaloes affected with incomplete cervical dilatation post-uterine detorsion.

Conventional induction protocol (CIP) of calving in buffaloes employs the intramuscular (IM) administration of dexamethasone (40 mg) and cloprostenol sodium (500 μg). If there is no progression in terms of cervical dilatation, then a second dose of cloprostenol sodium (500 μg) is administered intramuscularly. This protocol possesses certain demerits: (1) a wide range of response time intervals, and (2) increased risk of fetal membrane retention.

A Curious Case of Methemoglobinemia Complicating a Pediatric Live Donor Liver Transplantation Surgery.

Background: Pediatric live donor liver transplantation (LDLT) surgery is by itself a complicated surgery. Added to the difficulty in the operative technique are the complex preoperative work-up, optimization, and postoperative treatment. Intraoperative events and immediate postoperative recovery are important in graft function and the patient's overall recovery.

Homology between cattle bull sperm and bacterial antigenic proteins viz a viz possible role in immunological infertility.

This study was carried out to investigate the possible presence of identical sperm and bacterial antigens which may cause similar antisperm antibody production leading to lower fertility. Cross-reactive antigens of cattle bull spermatozoa and different bacteria including Escherichia coli (E. coli), Bacillus sp.
