The Beef Cattle Genetics And Their Rearing

By Linda Cantrell


It consists of the use of beef cattle that are superior in terms of their genetic make up to take the role of the parents of the next generations. Since the main aim of the farmers and all those individuals who rear these beef cattle is to make profit, Beef Cattle genetics modification is the answer to their quest. It measures the farmer ability to reach their specified set targets. The Angus and the Hereford are examples of beef cattle.

Through the use of genetics, species such as the Belgium Bluebull have resulted. This breed is often defined by the presence of excess muscles in their body and their meat is also of a great amount. They gain weight at a high rate and they usually consist of about 40% more extra muscle compared to other ordinary beef that have not been genetically modified. This is a profit to the farmers since they are able to fetch more money in the market.

There is however demerits to this process because it leads to the calves developing very large tongues and this may be detrimental to them. Also, due to their very large size, parturition becomes very painful hence the species have to undergo caesarian section which at time wounds the cow preventing them of bearing more calves.

Another method of improving production is by the use of Artificial Insemination (AI). Frozen semen is what is used in this case. The process involves the insertion of frozen semen into the reproductive tract of a cow. Creation of uniformity is the main advantage of this process as the calves are usually of the same age and their genetic make-up is the same. In the market, the species that possess this trait fetch a higher price.

Hybridization is another form of genetic engineering. This is also referred to as selective breeding. It is done by crossing of two breeds that have different but desirable traits or genes to produce what is known as a hybrid offspring that has both of the traits in it. The result the production of bulls for meat which has high quality beef which is a benefit to farmers.

Cloning is the process that leads to the productions of a generation of offspring that have the same genetic makeup. Cloning results from the cells of an individual organism. Farmers prefer this because the qualities that they most desired in their cattle are achieved.

Its disadvantages are that the resultant offspring always appear weak, oversize, fall sick frequently and they may end up dead. Due to this factors there are a group of farmers who do not encourage the use of genetic modification to improve production as they see it as tempering with their genes and natural formation.

The majority of these beef cattle keepers use their genetics to gain profit from increased productivity. With today population trend, the population is growing and most people are able to afford meat and to meet this demand genetic engineering of these species should be used but that type that leads to undesirable consequences should be avoided to reduce expenses incurred in case of deaths.
