Sexed Semen: A Boon for Indian Dairy Farming
Abstract: The sexed semen technology is a breakthrough technology for sorting of X and Y bearing chromosome to produce progeny of a desired sex with 80–90% accuracy. Among several methods of sorting X and Y bearing semen, flow cytometry is the best method, as it doesn’t changes more sperm morphology. The sexed semen technology has several advantages like production of more female calves and more milk, lowered risk of dystocia, increased …

Thermodynamic Irreversibility in Semen Transport
Abstract: Sperm ejaculation is a vital reproductive process that involves both complex biological functions and energetic mechanisms. Beyond the physiological aspects, thermodynamics offers a framework to analyze energy conversion, exergy use, and irreversibility during sperm activity. ATP provides the main source of exergy for motility, but part of this energy is inevitably lost as heat and entropy generation, reflecting inefficiencies in the process. Because heat regulation directly affects metabolic rates, motility …

A Duplex PCR for Simultaneous Detection of Brucella and Bovine Herpesvirus – Genome in Clinical Samples
Abstract: Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 A disease-free germplasm is a prerequisite for getting healthy progeny. Many diseases are transmitted through semen either by natural service or artificial insemination causing reproduction failure and economic losses. The intermittent excretion of Bovine Herpesvirus-1 (BoHV-1) and Brucella in semen and their transmission through artificial insemination has been recorded. PCR has become an invaluable tool because of speed and simplicity with …

Significance of Artificial Insemination in Poultry
Abstract: AbstractArtificial insemination (AI) involves the deposition of semen into female reproductive tract manually. It starts from the collection of the semen from the male and its evaluation in terms of motility, viability and concentration followed by its deposition into female reproductive tract. Sexual maturity in both male and female bird occurs at 18 weeks of age. One ejaculate of a male can cover up 20 female birds by using AI. …

The Effect of Vitamin C on the Reproductive Functions of Paraquat Intoxicated Male Albino Rats (Rattus norvegicus)
Abstract: Paraquat (PQ) is a bipyridylium herbicide applied around trees in Orchids and between crop rows to control broad-leaved and grassy weeds. Its oxidation results in the formation of superoxides and supernitrite species which causes damage to cellular components. Studies have implicated PQ as one of the pesticides that contributes to the reduction in male reproductive functions in humans and animals during exposure. This study, therefore, determined the antioxidant effect vitamin …

A Bull Breeding Soundness Evaluation System with Greater Emphasis on Molecular Genetics
Abstract: Bull is known to be half of the herd. As bull contribute large number of progenies to the next generation as compared to females so determining the potential fertility of the bull is much more important than determining the fertility of any individual cow. It becomes critical to study and analyse the breeding potential of a bull before breeding season for getting best out of progeny. Breeding soundness evaluation (BSE) …

Extensive Review on Ebola Virus
Abstract: Although Ebola virus (EBOV) is transmitted by unprotected physical contact with infected persons, few data exist on which specific bodily fluids are infected or on the risk of transmission. Therefore, we tested various clinical specimens from 26 laboratory-confirmed cases of Ebola hemorrhagic fever, as well as environmental specimens collected from an isolation ward, for the presence of EBOV. Virus was detected by culture and/or reverse-transcription polymerase chain reaction in 16 …
