Study Notes

Milk Pricing Principles

Quality indicators such as protein and fat levels exert a significant influence on milk pricing.
High Total Bacterial Count (TBC) reduces milk price by 0.5 cents per liter.
High Somatic Cell Count (SCC) decreases milk price by 0.15 cents per liter.

Dairy Terminology

A female animal that has not yet calved is referred to as a heifer.
A weanling is a young animal aged between 9 months and a year.
A cow is defined as a female that has had at least one calf.

Dairy Breeds

The Holstein breed is distinguished by its black and white coloration and is renowned for high milk production.
Norwegian Red is recognized for its red color and is a significant dairy breed in Norway.
The Kerry breed is characterized by small size and efficiency, often raised in temperate climates.

Milk Production Systems

Low-cost milk production systems in Ireland primarily utilize grass as the main source for producing milk.
Steers are defined as castrated males, essential for managing dairy herd dynamics.

Heifers and Calves Management

Heifer calves are primarily reared to eventually replace older cows in the dairy herd.
Colostrum is crucial for calves, containing high levels of immunoglobulins vital for immunity.
In colostrum, protein is present in higher percentages compared to fresh milk.

Calf Diet and Health

Providing a 'scratch factor' in a calf's diet helps develop the rumen microflora, promoting better digestion.
Calves should be tested for Bovine Viral Diarrhoea (BVD) before deciding culling.
Calves are typically separated from their mothers once they are weaned onto powdered milk, after the first week.

Herd Management Practices

'Grading up' the herd enhances overall productivity and genetic merit.
Early introduction of diets not suited to calves may lead to challenges due to underdeveloped rumens.
