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.

The Belgium Blue bull is as a result of significant improvement of production through the use of genetics. It is characterized by the presence of excess muscles and also a great amount of meat. They have an additional 40% of muscles and their ability to gain weight is tremendous in comparison to other breeds. This is economically beneficial to farmers because this beef from the cattle is sold and fetches a lot of money.

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.

The farmers can also use hybridization to improve productivity. Two meat cows with the same traits or genes are crossed so that the offspring may end up having both traits. This offspring is known as a hybrid. The advantage of this is that high quality beef is produced and it is a benefit to the farmer.

A group of offspring that are genetically similar can be produced from the cells of a particular organism and this is what is called cloning. This results to their production have desired qualities and this is an overall advantage to the farmers who are in love with rearing of cattle especially this particular species.

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.

In summary, economic profit is the main reason behind the use of genetic modification to improve production of this species. The rate of these animals falling sick is also greatly reduced. In the world of today, many people are now able to afford bulls hence the demand is going up. Genetic modification is seen to be the answer to meet these demands. However, processes that have negative consequences to the animals are better avoided.
