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

• higher conception rates

• less uniform calf crop

• lower level of management reqiured

• reduced breeding and calving seasons

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

• 6 months

• 12 months

• 18 months

• 24 months

In breeding flock management, eggs are gathered several times per day and packed:

Hatching eggs are fumigated to help prevent the spread of:

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

• double farrowing

• multiple farrowing

• seasonal farrowing

• single farrowing

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

The highest percentage of all reproductive failures in cows is caused by:

• diseases

• parasites

• underconditioned, thin cows

• weather conditions

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
