Life stages
Unweaned
Growing
Bulling
Lactating herd
High yielding at beginning of lactation
Low yielding
Dry cows (usually) heavily pregnant
Other things to consider
Sick/lame
Mastitis
Prevent spread
Separate milk containing antibiotics
Calving
Handling
Milking
Bull
Run with adult herd?
Additional accommodation ?
Feed
Water
Bedding
Waste
Common considerations across all life stages
Ease of management
Things often don't get done properly as staff can't do quickly and easily
Hygiene
Lameness
Ventilation
Welfare codes
Cow flow
Stockperson
Animal
Calm as possible
Intervention/restraint
Lactating cow
1/3 of day feeding
1/3 of day ruminating
1/3 day resting
Lameness from standing too much
Locomotion
Parlour access
Water
drink 100 l per day
Observation
Health
Oestrus
Restraint
No stressors
Straw yard
Advantages
Cow comfort , choice of lying position
Decreased lameness
Disadvantages
Bedding , more required , less choice
increased mastitis
Bedding management
Compost effect
Daily top up
Complete clear out 3-6 weeks
Need 2-3 tonnes per cow per 180 days
Issue in some parts of country for that amount of straw
Design
Lying space
Min 7.5 m2
Better 1.25m2/1000 l
Loafing space 3m2
Often combined with area they can feed
Bedding
Must be dry
Storage of straw
Separated from bedding (less faeces in bedding)
Concrete lip - clear step
lots of access points
stops concentration of muck at one entrance point
Long and narrow
Cattle like lying close to wall
More rest
Water trough into loafing area
No acesss from bedding side
Cows urinate and deficate before and after eating and drinking
drier bedding
Good ventilation
See shed designs in intro to housing
Temp around 8/10 degrees
Roof lights
Not direct sunlight on cattle
Heat stress in summer
Dot around
Cubicle system
Advantages
Higher cleanliness
Efficient use of space
Individual lying space
Reduced bulling
Bedding advantages
Design
Rows of bed cubicles
Loafing area
Cow requirements
Lunging space
Cows struggle to get up and stand instead - increases lameness
Cows lie on an angle
Leg space
Rumen space
Too wide - cow lies diagonally and faeces gets in bedding
Length
Cubicle components
Length
2.3m open front
2.6m against wall
Width1.2m
Kerb 15-20cm
Brisket board 1.6-1.8 m
Stops cow going too far forward in cubical
Neck rail
Same function as brisket board
Can cause problems
Divisions
Bedding
Sand
Doesn't provide bacterial growth
Mattress
Waterbed
Recycled waste
Sawdust
Knee drop test
Cow comfort quotient
How many cows lying correctly out of total number in group engaging with cubicle
Min %
Do this 4hrs after they have fed
Also standing quotient
Knee drop test
Number
Legal requirement - 1 cubicle per cow
Better 5-10% extra - lower ranking animals have choice who they sit next to
Cross over points (bedding to loafing area)
End of each row
Every 20 cubicles
Stops dead ends and bulling
Flooring
Clean quickly (slurry management)
Automatic scrapers
Disadvantages
Cows infant get hit by wave of flurry
Spreads disease
Digital dermatitis
Mastitis
Can cause injury
Overcoming these
Wide passage way - slurry is spread out
Flushing with water
Spreads disease
Slipping
Provide grip
Grooving into flooring
Hexagonal grooves allow non slip in all direction
Test
on hands and knees - hurt?
slip on water?
Slopes not too steep
Keep ways short
Avoid right angles
Feeding
Trough space/cow
10cm per 1000 litres or 100kg BW
More space = less aggression
Smooth surface
cow preference a
cleaning
Cow Reach
doubles if feed platform 20cm higher
Food needs to be pushed back towards cows
Personal space
Passage way must be big enough to allow one cow past when another is drinking
Passage between to points
With water path 3.6m
without 2.4m
Feed passage 4.6m
cubicle passage 3m
Water
Peak points
After milking
Sunset
Daily 100l/ cow
Top up flow rate
Cow can drink 15-20lmin
Cleanliness and quality
Gold fish test?
Dry Cows
Hygiene
Better hygiene reduced mastitis
Calving area
Intervention/restraint
Don't get trapped if go down
Grip and comfort
Straining
Calving boxes?
Interventions
AI stalls and crush
Bull housing
Visual contact with other cattle
Feed and water from outside
Segregate for bedding
No accidental access
Restraining facility in pen
Pasture
Cow tracts
Common problems
Gateways
Poor drainage
Machinery co use
Poor surface
Water at Pasture
Access
Distance
If way away then cows like to travel together
Larger trough
Fencing
Effective containment
Injury Risk
Predators/biosecurity
Inclement weather
Shade
Wind shelter
Mastitis
Parlour hygiene
Housing to cow
Cluster to cow
Cow to Cow
stocks people
Clear identification of mastitis cow
