Meloxicam and levamisole administration ameliorates FMD vaccination stress on frozen semen attributes in Sahiwal bulls.

Vaccination-induced allergic reactions in bulls raise both body and testicular temperatures, leading to germ cell damage, epididymal dysfunction, accelerated testicular ageing, and increased sperm abnormalities that ultimately degrade semen quality. This study aimed to ameliorate vaccination stress and improve semen quality using meloxicam and levamisole. The present study was conducted at the Artificial Breeding Research Centre, ICAR-NDRI, Karnal, Haryana, with twelve Sahiwal breeding bulls that were divided into four groups: Group I (Control), Group II (Meloxicam), Group III (Levamisole), and Group IV (Meloxicam + Levamisole).

Effect of age-associated oxidative stress on sperm viability, acrosomal integrity and sperm apoptosis and DNA fragmentation in Sahiwal breeding bulls.

Sperm motility is the prime functional attribute for semen quality and fertility of the bull. However, the bull's age directly affects the semen quality, and the bull's fertility and productive life decline with age. Even though research on age has been conducted in the past, it is still unclear how old a bull should be maintained at artificial insemination centers.

Bovine reproductive immunoinfertility: pathogenesis and immunotherapy.

Infertility is one of the primary factors for cattle reproduction in the present scenario. Reproduction-related immunoinfertility mainly involves immunization against the antigens related to reproductive hormones (LHRH, GnRH, Gonadal steroids, PGF2α and oxytocin), spermatozoa, seminal plasma and ovum. Anovulation, delayed ovulation, sperm immobilization, failure of fertilization, prolonged uterine involution, extended calving interval, prolonged post-partum estrus and reduced conception rate could be a result of immunoinfertility that occur due to the blockage of receptor site by antibodies formed against hormones, sperm and ovum.
