Genetic Effects of Intensive Breeding

What is Intensive Breeding?

Intensive breeding is a breeding system which aims to get a specific desired genetic trait from a species. Intensive breeding is done in order to get various genetic variations (Colour variation – Figure 1) within a certain population, which will eventually lead to an economic incentive higher than that of an original colour variation species.

Intensive breeding has got its advantages and disadvantages. Selection for a rare trait is desired for the monetary benefit, where many game farmers don’t realise the drastic negative genetic impacts.

Hunting has always been a past-time where a lot of enthusiast participate in the hunting of wildlife living in their natural environment. They find pleasure in the stalking of the animal and finally bringing back the trophy (the hunted animal). These enthusiast would not get the same pleasure from the stalking and hunting of animals kept in captive conditions. People have hunted for specific traits which make the individual animal more valued than the rest of the individuals within the population. Some have also hunted just for the pleasure, and not for any specific reason. This practice has however had long-term effects on the genetic make-up of wildlife species.

Does the intensive breeding of game on game farms contribute to the protection and conservation of species?

In this day and age, many animals are critically threatened and could become extinct at a very fast rate. A few mentionable species in South Africa is the Cheetah (Acinonyx jubatus), the Rhino, Roan (Hippotragus equinus) and Sable Antelope (Hippotragus niger), and the Wild dog (Lycaon pictus).

The cheetah is listed as Vulnerable on the IUCN Red List status (Durant, et al 2008). ...
