Gender Pre-selection in Farm Animals
By Syed Javed Hassnain
To produce an offspring of predetermined sex remained a challenging task for scientists of all eras. Different practices have applied to achieve desired sex of an offspring. Some theories are as old as the time of Greek philosophers, for example, they had believed that female develop on the left side of the utes and male fetus on the right side. Even as the 18th century there was those who thought that sperm from the right testes produced the most male and that sperm from the left testes produces the most females. Coincident to theories for gender control in human, various approaches emerged and applied to livestock.
The development of science and scientific technology had unveiled lots of facts of nature, life and environment of this universe. The advancement in scientific knowledge rejected the unscientific ancient theories applied on different aspects of life. It is now extremely well known that X- and Y-chromosome present in sperm and ovum control reproduction of an offspring. Each sperm carries either X- or Y- chromosome; on the other hand, ovum carries only X-chromosome. The ovum fertilizes by a sperm bearing Y-chromosome produce a male offspring. However, X-chromosome bearing sperm fertilizes the ovum, female offspring bear. The first scientific theory: about the control of parental sex reported by J.L. Lush (`1925). The basis of Dr. Lush’s research was the potential differential density of X- and Y-chromosome bearing sperm in the rabbit. Since then, a scientist focuses their research to separate X or Y-chromosome spermatozoa and then fertilizes the ovum with preselected sperm to produce offspring of predetermined sex. For this purpose, different techniques of physical segregation like centrifugation, density gradient, filtration, sperm surface charge have used so far. Unfortunately, excellent results could not be produced through these techniques.
Surprisingly, nobody paid attention towards the role of ovum in controlling sex of the fetus. It is the first time we attempted to recognize the role of ovum in controlling gender of a fetus in large animals. We hypothesized that the ovum under some specific environment can also control the sex of the fetus. The special environment around the ovum can be created by in two different circumstances to the animal. First environmental creation is enables ovum to get fertilized only with sperm bearing Y-chromosome and produces a male calf. In the second environment, Y-chromosome bearing sperm repel by the ovum, and only X-chromosome bearing sperm can fertilize the ovum resulting birth of a female calf. The control of prenatal sex through manipulation of an ovum is much easier as compared to the separation of X- and Y-chromosome bearing spermatozoa which are majorly affected, time consuming and also risky. However, controlling gender through manipulation of the ovum is a safe and reliable technique which could be applied equally through natural mating or artificial insemination. Through this technique, we have produced 90% accurate results in the trials conducted during the time of last 20 years. The name given to this technique is “PAK SHAHPUR CHOICE SEX MEACNAISM”. This technique would have a significant impact on the genetics and economics of livestock production. Sec pre-selection in livestock would provide a considerable advantage for producers seeking improved genetics improvement impressive performance efficiently and greater flexibility in livestock management. Selection of gender through this technology could make formers the choice sex offspring. Because the dairy former has little use for most bull calves, the use of this technique to produce only females would get milk production more efficient. In beef cattle, the male grows at a faster rate than the female. Therefore, they prefer, male for meat production. In addition, the ability to specify male or female offspring should shorten the time required for genetic improvement since desirable traits or regularly associates with one or other parent.
Keeping in view all these advantages of gender pre-selection offspring, it is now imperative to produce male or female of calf at your own choice. Fortunately, it is now possible through “PAK SHAHPUR CHOICE SEX (PSCS) MEACNAISM”.
The lunar gravitational forces are much more powerful, and these forces have it effects. Newton was the first person who discovered the law of gravity. First time, he explained that the gravitational attraction of astronomical masses to produce tides. He also explained the origin of the tide-generating forces is the lunar and solar gravitational attraction in his theory of Universal Gravitation. Scientists have proved and admit that the lunar forces have effects on female ovulation. Scientists also have admitted that moon phases have effects on epilepsy patients. Scientists have proved and admit that the lunar forces have effects on female ovulation. Amazingly, we have discovered that the lunar gravitational attraction, the lunar cycle and the moon phases are a natural mechanism of determination of gender sex in farm animals. We have trialed both on sperm and ovum in different moon phases. Semen collected in one ejaculation could not produce same results either male or females only. However, ovum produces same results in same moon phase. The lunar gravitational attraction is a natural mechanism to determinant gender sex in farm animals. Therefore, which naturally mature ovum discharge and fertilize in the first fortnight of the new moon will produce male offspring. However, a naturally mature ovum discharge and fertilize in the second fortnight of the moon will produce female offspring.
Controlling gender through manipulation of the ovum is an easy and reliable mechanism, which could be applied equally through natural mating or artificial insemination. Discovery of such mechanism should give a lot new fields to scientist for their research. This mechanism would have a significant impact on the genetics and economics of livestock production. Selection of gender through this mechanism could give farmers the choice of sex of offspring. Keeping in view all these advantages of general pre-selection offspring, it is now imperative to produce male or female calf at your own choice. Fortunately, it is now possible through Pak Shahpur choice sex (PSCS) Mechanism.
The following planning is to bring trails in the vast area, within this country and also other countries at International level. We are also trying to counter check this mechanism by using flow cytometrically sorted sperm.
