Q

Breeding policy :
AI

A

-All AI’d
-50 highest EBI cows receive sexed semen AI

Q

Feeding regime:
Annual feed budget:
Lactating Cows:

A

-600kgs conc for lactating cows , due to high-quality grass-fed to cows and the high genetic merit of the herd

-Parlour in spring 4kg/day 16%CP feed

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
Feed budget Clonakilty:
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
If K levels are low what do you spread?
-Slurry Potassium = K
26
If P levels are low what do you spread?
-Fertiliser Phosphorus
27
What's the optimal PH?
-6.2-6.5 Paddocks low in it need lime application Paddocks high need sulfur
28
Fertiliser Plan:
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
Slurry:
LESS Alternate between fertilizer Application rate of 5000 gallons /ha
30
Silage:
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
PHD Title
Effect of sward type and nitrogen fertiliser application rate on the productivity of spring milk production systems
32
Grass activities for PHD
-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
Reseeding
2 different blocks of 4 acres Block 1: Diploid and tetraploid seeds used Diploid- faster establishments Tetraploid- Higher forage quality Per acre mix -Aston energy 8kg -Moira- 4.5kg -Chieftain- 1kg -Crusader- 1kg Block 2: -Aston Energy 8kg -Moira- 4.5kg Field was ploughed , Chain harrowed Rolled
34
Common issues in dairy herd and beef herd: What do you give them?
-Mastitis 33CC of synulox tubes for 3 days -Lameness Regular foot trimming , pinstrip to disenfect
35
Routine preventative Medicine: and why ?
-IBR- viral disease , respiratory, reproductive, systematic issues -Copper Bolus -Lepto- Aportions, stillbirth -BVD- Bovine Viral Diarrahea -Oral drench -liverfluke
36
nitrates directive :
Farm is allowed 170kg of N
37
Derogation: Stocking rate of full farm:
There in 250 but needs to be reduced to 220 for next year. Full stocking rate is 2.9 / ha Theys opted into the low protein diet measure to reduce there kg/N/Cow
38
Protected urea
There spreading 46% protected urea on soil- reduce N losses and improve N efficiency
39
Housing :
242 cubicles Crush Drafting system Bailing unit
40
Parlour:
20 unit dairymaster herringbone parlour that has ACR's
41
Washing routine for parlour:
Acid wash Monday, Wednesday, Friday Hot was every other day
42
Milk recording:
-Tuesday evening and Wednesday morning -Monitors trends and overviews overall herd health -Place the bottles on milk metre and turn it to test when milk recording to collect samples from every cow.
43
Milk tank:
Panco milk tank -15,000 litres -Every 3 days collection
44
Calves when born:
-3 litres colostrum, iodine, jacket , tagged, brought over to calf shed
45
Feeding calves iin small shed:
3 litres in morning and evening wholemilk from parlour -Loosepen get whole milk in 12 teeth bar with milk guard mixed through milk -prebiotics -Get calfage and crunch
46
Calfage composition:
CP- 20% CF- 7%
47
Dairy calf to beef animals:
