Study Notes
Dairy Cattle Breeds
- British Friesian: Known for high milk yield and adaptability to pasture.
- Holstein: Predominantly black and white, recognized for exceptional milk production levels.
- Holstein-Fresian: A variation emphasizing milk quantity while retaining some characteristics of the Holstein.
- Ayrshire: Originating from Ayrshire in Scotland, noted for efficiency in milk production from grass.
- Jersey: Small, cream-colored cattle prized for rich, high-butterfat milk.
- Kerry: A traditional breed from Ireland, known for its high milk yield and resilience.
- Montbéliarde: French breed, recognized for producing quality milk with good fat and protein content.
- Norwegian Red: Valued for milk quality and disease resistance; contributes to genetic diversity.
- Jersey x Holstein-Friesian: A crossbreed aiming to combine high yield and high butterfat content.
Dairy Terminology
- Calf: A young dairy animal up to 9 months old.
- Heifer: A young female that hasn't had a calf.
- Cow: A mature female that has calved.
- Bull: An uncastrated male bovine.
- Steer/Bullock: A castrated male bovine.
- Weanling: Animal aged between 9 months and a year.
- Yearling: An animal aged from 12 months onward.
Milk Production in Ireland
- Based on low-cost systems; milk primarily sourced from grass grazing.
- Milk prices are determined monthly, impacting farmer income.
Milk Price Scenarios
- Factors affecting milk price include protein and fat content, processing charges, and quality bonuses.
- Example Payment Structure:
- Farmer A (3.9% protein, 4.1% fat):
- Total milk price: 36.45c/l; earned €5,832.
- Farmer B (3.4% protein, 3.9% fat):
- Total milk price: 29.33c/l; earned €4,693.
- Farmer A (3.9% protein, 4.1% fat):
- Higher protein and fat content lead to increased prices per liter.
Calf Rearing
- Two main purposes: replacement heifers for dairy and fattening calves for beef.
- Early diet must account for undeveloped rumen in calves.
- Sequence of feeds after birth includes colostrum, fresh milk, powdered milk replacer, and gradual introduction of solid feeds.
Colostrum Benefits
- Colostrum contains critical nutrients and antibodies vital for calf health:
- Higher protein (14.9% vs. 3.2%) and fat (6.7% vs. 3-4%) compared to fresh milk.
- Vital immunoglobulins in colostrum provide passive immunity.
Health Management
- Bovine Viral Diarrhoea (BVD): A significant viral disease that requires identification and culling of affected animals.
- Effective housing should ensure sufficient space and hygiene for calf rearing.
Weaning Management
- Considerations for transitional feeding strategies as calves move off a milk diet.
Year 2 – Replacement Heifers
- Selection of heifers for herd replacement based on productivity and health of older cows.
- Grading Up: Enhancing herd genetics by replacing lower-yield cows with high-yielding heifers.
