Livestock(牲畜） cloning is the practice of cloning sheep,cattle and other livestock species as a way to improve efficiency. The basic idea behind livestock cloning is to clone animals that have certain qualities,such as cows that produce more milk or meat. 1 However,this practice is very controversial,and livestock farmers have been hesitant to adopt it fully because of public opposition and certain inefficiencies.

In technical terms,livestock are cloned by taking cells from one animal and using them to fertilize eggs(使卵子受精) .Scientists take the fertilized eggs and put them in female animals. 2 Many animals are bom with abnormal shapes. Scientists are looking for ways to improve the process and make it less expensive to adopt on a wider scale.

3 For example,if farmers were able to take only their very best animals and recreate them many times,they could potentially be more productive.

There are also some potential problems with cloned livestock. 4. For example,when a disease hits,there are usually individuals who cannot be harmed by the disease or are more resistant,and they will generally survive. If all the animals were genetically (在基因方面) identical or similar,this sort of disease could totally destroy an entire generation of livestock,leaving the world with a massive food shortage.

In addition to concerns about genetic diversity,there are other concerns about cloning. 5 There are also some people who worry that livestock cloning research may be a gateway to introducing human cloning,which is widely disapproved of.
