Animal Reproduction and Biotechnology

Arranging the breeding schedule so that groups of sows farrow at regular intervals throught the year is called:

• double farrowing

• multiple farrowing

• seasonal farowing

• single farrowing

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:

• experience

• knowledge

• speed

• a veterinarian's license

Body conditioning and its effects on conception in cows are very important because cows should have and wean a calf every:

• 18 months

• 6 months

• 12 months

• 24 months

Which preventive 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

• Storning eggs at 80% humidity

Hatching eggs are fumigated to help prevent the spread of:

• egg-borne diseases

• external parasites

• internal parasies

• nutritional disorders

In confinement swine production, a management practice that increases conception rates is to:

• breed females at least twice each heat period

• breed females once each heat period

• breed gilts during the first heat period

• check for standing heat each week

Equipment needed for palpation includes:

• coveralls and boots

• obstetrical chains or rope

• a plastic sleeve and lubricant

• a thermometer and a watch

When a beef cow is artificially inseminated, a gloved hand is inserted into the animal's rectum to guide the inseminating rod through the:

• cervix

• fallopian tube

• infundibulum

• vas deferens

A major disadvantage of synchronization of estrus in cows and heifers is:

• higher conception rates

• less uniform calf crop

• lower level of management required

• reduced breeding and calving seasons

The process of feeling the reproductive tract of a cow to determine pregnancy is:

• artificial insemination

• palpation

• parturition

• sterilization
