25
What is done to heifer calves to transition them into heifers?
-Moved to pens of a similar sized group starting with 3-5 calves per pen to larger pens around 4-5 months -Diet is transitioned throughout to meet dietary requirements as they age
26
What is the estrous cycle?
The reproductive cycle that the female enters after puberty that continues throughout most of her life
27
What is the estrous cycle controlled by?
Hormones from the ovary and the brain
28
How can a pregnancy diagnosis be made?
-Rectal palpation -Transitional ultrasound
29
What is a heifer that has been bred called?

30
How long is a cow's gestational period?
9 months
31
When should a heifer have their first calf?
2 years of age
32
What is another name for a heifer who has had their first calf?
A first calf heifer
33
What is freshening?
When a cow starts producing milk after having a calf
34
What is the action to stop milking a cow called?
Dry off
35
What is an open cow?
A cow that is not pregnant (normal in the first 2 months post-calving)
36
What is a dry cow?
A cow that is not being milked and stops lactating
37
What is a dry period?
A rest period that lasts 2 months prior to calving when the pregnant cow is not being milked to have the udder rest and prepare for the next lactation
38
What is lactation?
The period of milk production post calving, the optimum is 10 months
39
What is a calving interval?
The time from one calf born to the next calf born, optimum time is 12-13 months
40
What is the voluntary waiting period?
The period of time after calving before rebreeding, the optimum time is 60 days
41
What are the 3 kinds of operating systems?
-Complete system -Milking operation only -Heifer farms or heifer raisers
42
What does the complete operating system do?
-Perform all aspects of dairy management in one location -Calf rearing -Growing food for cows -Milking
43
What do the milking-only operations do?
-Sell all calves and buy replacements -Do not grow food for cows on property (purchase from other farms) -Larger with less surrounding land -Large number of cows
44
What do heifer raiser operations do?
-Take in heifer calves from milking operations and raise, breed, and return/sell them prior to calving -Accept heifers of different ages
45
What requirements does good housing require?
-Clean, dry, comfortable resting area -Easy access to feed -Easy access to water -Fresh air movement -Easy, safe way to get milked 2-3 times per day -Easy means of restraint for health checks, breeding, and good care
46
What do farmers look for in their housing?
-Labor efficient -Economical -Safe for workers and cows -Environmentally friendly
47
What are the 3 types of housing?
-Barn (free stall and tie stall) -Pasture -Dry Lot
48
What is a free stall barn?
-A loose housing system that allows for free movement of cows throughout the barn -Consists of stalls or beds that the cows can stand or lay in by choice
49
What are the pros of a free stall barn?
-Clean, controlled environments for cattle -Decreased bedding expense compared to indoor housing -Ease of parlor access -Lower space requirements -Lower risk of teat and udder injuries
50
What are the cons of a free stall barn?
-High maintenance levels and costs associated with keeping environment clean and dry -If not well maintained, increased risk for disease
51
What is a pasture?
Cows are kept on pasture grazing and only come in to be milked
52
What are the pros of a pasture?
-Decreased feed costs -Good pasture is an adequate form of nutrition -Cows are free to walk around outside (beneficial to overall health)
53
What are the cons of a pasture?
-Less changes in nutrition throughout production cycle -Harder to monitor cattle who may be showing early signs of disease -Less control over environment
54
What is a dry lot?
An open dirt lot with no vegetation
55
What are the pros of a dry lot?
-Cows are free to walk around outside (beneficial to overall health) -Monitoring is easier compared to pasture
56
What are the cons of a dry lot?
-Feed costs are higher compared to pasture -Less control over environment -Cattle cooling can be a concern
57
What are the types of bedding for cattle?
-Compost -Geotextile mattress -Paper -Sand -Sawdust and wood shavings -Straw
58
What are the aspects of compost bedding?
-Use of accumulated manure for bedding in a pack barn setting -Starts with 12-18 inches of sawdust -Has to be aerated 2x daily -Dry sawdust needs to be added every 2-5 weeks -Requires excellent ventilation and management -Low cost -May increase risk of infection for mammary glands if not managed well
59
What are the aspects of geotextile mattress bedding?
-Used in tie stall or freestall barns -Waterproof exterior filled with rubber crumbs or foam -Marketed as no bedding required but additional bedding increases cow comfort -Cows stay clean and show preference towards mattresses -May increase lameness incidence
60
What are the aspects of sand bedding?
-Low cost -Improves cow cleanliness -Low bacterial counts -Difficult to dispose of -Cows prefer other bedding options given the choice
61
What are the aspects of sawdust bedding?
-Easily broken down when disposed of (organic) -Decreases low lameness and improved lying time -Very absorbant -Increased bacterial growth
62
What do we look for in bedding for cows?
-Comfortable for the cow -Dry -Nonabrasive -Cost efficient -Labor efficient
