Q

Composition of feed in parlour:

A

CP- 14%
CO- 4.5%
CF- 9%
Ash- 9%
Magnesium- 1.4%

22
Q

Dry cows and replacement heifers feed:

A

-No ration fed, silage over 70% DMD
-Experimental cows get their treatment silage when housed in wintertime

23
Q

Spring rotation planner:

A

4th March amount grazed was 29%
18th March amount grazed was 57%
1st April amount grazed was 66%
-All due to bad weather and wet ground

23
Q

Grassland management:
-rotation
-pasture base info
-Grass measuring
-Fertiliser

A

-Rotational grazing
-21-28 day rotation depending on the time of year
-Farm walk every Monday morning, covers each field, DM is usually 17
-inputted into pasture base and
farm cover 665kg/DM/Ha
livestock unit-229kg/DM/livestock unit
growth 72kg/DM/ha
demand 47kg/DM/ha

-I grass measured the pre and post grazing heights in treatment fields
Average pre grazing height was 10cm
Average post grazing height was 4.5cm

FERT SPREADING

-25kg/N/Ha protested urea on 225kg/N/Ha treatment

-10kg/N/ha protected urea on 150kg/N/ha treatments following r
grazings

-No N on 75kg/N/ha treatment as its been reached

-

24
Q

Feed budget Clonakilty:

A

Closed season 6th December at 620kg/DM/Ha
Turnout at 15000kg/DM/Ha on 6th Feb
This year hopefully closing it at mid November at average cover of 600-700kg/DM/Ha

25
Q

If K levels are low what do you spread?

A

-Slurry
Potassium = K

26
Q

If P levels are low what do you spread?

A

-Fertiliser
Phosphorus

27
Q

What’s the optimal PH?

A

-6.2-6.5
Paddocks low in it need lime application
Paddocks high need sulfur

28
Q

Fertiliser Plan:

A

Total Values for the year:
N= 26,984kg
P= 3,908kg

Allocated fertiliser:
4.43 tonnes 0-10-20
4.21 tonnes 10-10-20
53.27 tonnes of protected urea

Typically 124kg/ha is spread depending on rotation every second rotation to slurry.

29
Q

Slurry:

A

LESS
Alternate between fertilizer
Application rate of 5000 gallons /ha

30
Q

Silage:

A

72 acres pit silage
12 acres white clover, rest perennial ryegrass.

12 acres for bales
4 acres red clover and rest perennial ryegrass
62 bales in total

second and third cut will happen

31
Q

PHD Title

A

Effect of sward type and nitrogen fertiliser application rate on the productivity of spring milk production systems

32
Q

Grass activities for PHD

A

-Etesia
-Walk 10 metres with plate metre,
record 10 measurments, grass was cut, record 10 more measurements from the strip.

Etesia grass was weighed in bucket and on large scales, a sample of this was placed in a bag and brought back up to moorepark this happened 2 times in every paddock.

V shaped snips 10-15 steps in each paddock before its grazed placed in bags and labeld to be tested for herbatages.

Grass in Moorepark is:
FROZEN
CHOPPED
FREEZED DRYED
GRINDED

Then they are quality tetsed in lab to analise :
SM
Ash content
CP
Water soluble carbs
DMD
OMD

33
Q

Reseeding

A

2 different blocks of 4 acres

Block 1:
