Sex Sorted Semen

Cattle Sex-sorted semen is sorted semen either to contain X or Y chromosome bearing sperms and the use of it would produce a desired sex i.e. male or female animal. In dairy sector preference is always given to a female calf and thus the use of X chromosome bearing sperms semen will be useful to produce maximum number of females.

Normal semen cells (spermatozoa) contain either X or Y-chromosomes and both these cells are present in a normal semen ejaculate or a semen straw. But ova released by female contains only X chromosomes. At the time of fertilization, if X chromosome from semen enters the ovum, then the resulting foetus will be a female (XX), and if Y chromosome enters the ovum then the resulting foetus will be a male (XY).

Therefore, in natural process there is an equal chance of getting male and female foetus. However, the advanced reproductive technology is able to separate spermatozoa bearing X or Y-chromosomes. Chromosomes are made up of DNA (De Oxyribo Nucleic Acid). X cells contain more quantity of DNA (3.8% more) than the Y-chromosomes. This difference in molecular weight is used to differentiate X and Y chromosome bearing spermatozoa. For separation of X and Y chromosomes, the technique used is Flow-Cytometry. Flow cytometry is a laser based technology used for cell sorting.

The main global player in semen sex sorting is Sexing Technologies (ST), USA. The sex sorting lab with its severe quality control, focusses on removal of dead, male sperm cells to ensure production of over 90% females – a unique aspect of this technology. Due to removal of the dead and unwanted sperms the sex-sorted semen will be highly viable and fertile.

Benefits of Sex-Sorted Semen Technology

Buffalo sex sorted semen is the need of hour. it benefits the farmer community as it hastens the production of replacement heifers, reduces dependency on purchase of heifers, less male calves, rapid increase in milk production, better use of constrained feed, fodder resources.

Use of Buffalo sex sorted semen will result in the birth of heifer calves 90% of the time as compared to non-sexed semen, which could result in birth of female calves only in 50% of the times either natural service (NS) or use of conventional semen for Artificial Insemination (AI). The additional heifer calves will help to expand the buffalo dairy herd to a faster pace compared to the use of conventional semen.

At present, we produce the Sex Sorted Semen of buffalo breeds like Murrah, Jaffarabadi, Pandharpuri, and Mehsana.
