Dairy Farming
Introduction to Irish Dairy Farming
Overview of dairy farming in Ireland as an essential agricultural sector.
Discussion of the production process and its implications.
Daily Operations and Practices on Dairy Farms
Role of veterinary assistance in dairy farming.
Importance of husbandry practices in maintaining a healthy farm environment.
Challenge of infectious diseases and production diseases in dairy cattle.
Examples include problems related to calving.
Understanding Calving and Lactation Cycles
Calving is the start of production for dairy cows.
Sequence of events leading up to and following calving:
Pregnancy: Average duration approximately 280 days.
Calving: Process that begins with uterine contractions.
Common signs of calving include isolation of the cow and changes in behavior (e.g., polled abdomen, elevation of heart rate).
Lactation: Cows produce milk for about 300 days post-calving.
Record and monitor for health problems during early lactation, especially the first 100 days.
Historical Context and Economic Impact of Dairy Farming
The shift in dairy production from self-sufficiency to exporting products.
Economic significance of dairy farming in Ireland:
Contributes approximately 10% of all Irish exports.
Accounts for 90% of the country's dairy exports.
Grass-Based System of Dairy Farming
Predominantly grass-based system with spring calving pattern.
Benefits of grass-based farming include:
Positive market perception of animal welfare related to grazing.
Relationship to minimal environmental impact due to sustained grazing practices.
Grass contributes significantly to the diet of dairy cows:
Fresh grass in summer and conserved grass in winter.
Dairy Cow Breeds and Breeding Strategies
Dominance of Holstein-Friesians in Irish dairy herds:
Genetic traits conducive to high milk production.
The approach to breeding for productivity and health:
Comparison of breeding success rates between Holstein and Jersey breeds.
Advantage of crossbreeding for reproductive performance improvement (
