Detection of estrus in Indian blackbuck: behavioural, hormonal and urinary volatiles evaluation

General and Comparative Endocrinology
Govindaraju Archunan, Thangavel Rajagopal


The determination of the reproductive status is one of the most important factors for effective wild life conservation and management, and effective use of assisted reproductive techniques like artificial insemination, in vitro fertilization/embryo transfer depends on the knowledge of the basic reproductive physiology. In this context the reproductive status of female blackbucks (Antelope cervicapra L.) was assessed by behaviour and determination, sex steroid hormones in faeces and urinary volatile compounds. The male and female blackbucks exhibited as many as 31 different reproductive/courtship behaviour patterns. Particularly, the males showed a more extensive repertoire: i.e. 23 behavioural patterns by territorial males, 11 by bachelor males and 4 by females. The behaviours such as, mounting, Flehmen, clockwise and anticlockwise movements were significantly higher in male blackbuck when exposed to estrus. By contrast, such courtship behaviours were completely absent in male when exposed to diestrus. It clearly indicates that, the estrus female produces specific chemical cues (pheromone) through urine, which would involve in attracting the conspecifics. In addition, the average faecal oestrogen concentration was significantly...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.


Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.


Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
