Animal Science II Large 5.03&5.04

A major advantage of synchronization of estrus is cows and heifers is:

• Higher conception rates

• Less uniform calf crop

• Lower level of management required

• Reduced breeding and calving season

Genetically engineered bovine somatotrophin (bST) given to dairy cattle results in:

• Increased milk production

• More fat and weight increases

• More fat and weight losses

• Reduced milk production

One of the major advantages of embryo cloning is:

• Genetically uniform offspring

• Genetically diverse offspring

• High costs

• Low success rates

The technology that opened the door for biotechnology to be used in animal reproduction is:

• Bioengineered vaccines

• Cloning

• Embryo transfer

• Monoclonal antibody technology

An area of biotechnology that uses monoclonal antibodies to improved animal health by increasing accuracy and reducing time is:

• Diagnostic testing

• Disease prevention

• Embryo transfer

• Parasite prevention

The biotechnology activity that can most rapidly increase the uniformity of cattle in a herd is:

• Artificial insemination

• Cloning

• Embryo transfer

• Purebreeding

In embryo transfer, the embryos are removed from the female donor by a process called:

• Drenching

• Flushing

• Infusion

• Sterilization

A major advantage of embryo transfer is that it speeds the genetic improvement of a herd of beef cattle from the:

• Bull

• Dam

• Siblings

• Sire

The genetics of cloned animals are:

• Different

• Identical

• Randomly mixed

• Recessive

The major problem that most people have with the use of biotechnology in animal production is the:

• Cost of development

• Education needed to use it

• Fear of the unknown

• Profits made by farmers
