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
Brucellosis testing, pregnancy diagnosis testing and treating scours are applications of:
Bioengineered vaccines
Bovine somatotrophin production
Embryo transfer
Monoclonal antibody technology
Removing a nucleus from an embryo before the embryo is implanted in the uterus wall and placing the nucleus into a mature, unfertilized egg cell is nuclear transfer or:
Artificial insemination
Crossbreeding
Embryo cloning
Palpation
The highest percentage of all reproductive failures in cows is caused by what?
Diseases
Parasites
Unconditioned, thin cows
Weather conditions
Body conditioning and its effects on conception in cows are very important because cows should have an wean a calf every:
6 months
12 months
18 months
24 months
Which preventative maintenance procedure is performed as a part of breeding flock management to prevent the spread of diseases from eggs?
Adding vitamins to feed
Fumigating with formaldehyde
Spraying with insecticides
Storing eggs at 80% humidity
A major advantage of synchronization of estrus in cows and heifers is what?
Higher conception rates
Less uniform calf crop
Lower level of management required
Reduced breeding and calving seasons
Since a person compares the feel and size of various parts of the reproductive tract to determine the stages of pregnancy, an accurate diagnosis requires what?
Experience
Knowledge
Speed
Veterinarian's License
A disadvantage of multiple farrowing compared to other farrowing systems is that multiple farrowing:
Increases investment per pig
Makes less efficient use of facilities
Requires better management
Spreads income throughout the year
The process of feeling the reproductive tract of a cow to determine pregnancy is what?
Artificial insemination
Palpation
Parturition
Sterilization
When a beef cow is artificially inseminated, a gloved hand is inserted into the animal's rectum to guide the inseminating rode through the:
Cervix
Fallopian tube
Infundibulum
Vas deferens
What type of breeding is used because of the low fertility problems and the large size of male turkeys?
Artificial insemination
Confinement breeding
Embryo transfer
Natural breeding
An advantage of using artificial insemination compared to natural breeding of beef cattle is that:
A trained inseminator is needed
A wider variety of superior bulls can be used
More equipment is required
More time is required
Arranging the breeding schedule so that groups of sows farrow at regular interval throughout the year is called:
Double farrowing
Multiple farrowing
Seasonal farrowing
Single farrowing
Hatching eggs are fumigated to help prevent the spread of:
Egg-borne diseases
External parasites
Internal parasites
Nutritional disorders
Equipment needed for palpation includes:
Coveralls and boots
Obstetrical chains and ropes
Plastic sleeves and lubricant
Thermometer and watch
In confinement swine production, a management practice that increases conception rates is to:
Breed females at least twice each head period
Breed females once each heat period
Breed gilts during the first head period
Check for standing heat each week
In breeding flock management, eggs are gather several times per day and packed:
In random positions
With dirt and manure on them
With large end down
With large end up
