What does SCC stand for and explain it :
Somatic Cell Count
It’s a key indicator of milk quality and udder health
High SCC indicates mastitis , reduced milk yield and quality
What does TBC stand foe and explain it?
Total Bacterial Count
Total bacteria present in milk.
An important indicator for milk hygiene and quality.
Breeding policy:
Calving pattern:
Focus on high EBI Holstein Friesians
-12 week calving period
-86% of herd in 6 weeks compared to national average of 67%
-Average age of calving cow 4 years and 11 months
Interval days-368 days in top 90% for interval days
Breeding policy :
AI
-All AI’d
-50 highest EBI cows receive sexed semen AI
-Fixed-time AI to ensure good conception rates:
Go through the whole process***
All cows have sense hub collars and
Remaining cows bred using high EBI bulls:
Herford, Angus, Limousine
Average EBI in clonality:
What’s the average in Ireland?
-€226
-€178
Clonakilty is ranked in the top 91% of average herds in Ireland.
What does EBI stand for?
Economic Breeding Index
Used to measure the genetic potential of a herd such as milk yield, fertility, calving performance and health into a single index
What is CBV
Commercial Beef Index
Index used to assess genetic potential of beef animals, particularly dairy beef calves.
It includes growth rates, carcass quality, feed efficiency
Whats the CBV in clonakilty?
€130

Feeding regime:
Annual feed budget:
Lactating Cows:
-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
March onwards 14%CP feed gradually reduced down to 1kg/day
Whats the N excretion rate of clon cows ?
Banding - middle bracket of 4501-6500kg/milk/year
-N per cow /year is 92kg
This is reduced to 89kg/N/cow/year cue to having con less than 15%
Composition of feed in parlour:
CP- 14%
CO- 4.5%
CF- 9%
Ash- 9%
Magnesium- 1.4%
Dry cows and replacement heifers feed:
-No ration fed, silage over 70% DMD
-Experimental cows get their treatment silage when housed in wintertime
Spring rotation planner:
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
Grassland management:
-rotation
-pasture base info
-Grass measuring
-Fertiliser
-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
-
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
If K levels are low what do you spread?
-Slurry
Potassium = K
If P levels are low what do you spread?
-Fertiliser
Phosphorus
What’s the optimal PH?
-6.2-6.5
Paddocks low in it need lime application
Paddocks high need sulfur
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.
Slurry:
LESS
Alternate between fertilizer
Application rate of 5000 gallons /ha
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
PHD Title
Effect of sward type and nitrogen fertiliser application rate on the productivity of spring milk production systems
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
Reseeding
2 different blocks of 4 acres
Block 1:

Rolled
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
Routine preventative Medicine: and why ?
-IBR- viral disease , respiratory, reproductive, systematic issues
-Copper Bolus
-Lepto- Aportions, stillbirth
-BVD- Bovine Viral Diarrahea
-Oral drench -liverfluke
nitrates directive :
Farm is allowed 170kg of N
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
Protected urea
There spreading 46% protected urea on soil- reduce N losses and improve N efficiency
