Study Notes

Dairy Industry Refrigeration

Refrigerated capacity is crucial for maintaining product safety and quality.
It ensures the sale of fresh milk, preventing spoilage and contamination.

Animal Mating Considerations

Ideal weight for animals at mating is between 300-350 kg.
Animals should ideally reach puberty at around 15 months to facilitate timely mating.

Livestock Management Traits

Docile temperament is preferred for easier livestock management, reducing stress for both animals and handlers.

Udder Health & Production

Good udder health is essential for optimal milk production.
It reduces the risks of health issues in livestock, ensuring better productivity.

Body Conformation & Health

Good body conformation contributes significantly to the overall health and productivity of livestock.
Healthy conformation supports better reproductive performance and milk yield.

Foot Health Significance

Maintaining good foot health prevents lameness in animals.
Healthy feet ensure adequate mobility, essential for grazing and overall well-being.

Importance of Colostrum

Colostrum is vital for a calf's early life, providing essential immunoglobulins.
Higher protein content in colostrum boosts the calf's immune system, aiding in disease prevention.

Feeding Transition for Calves

Calves are introduced to transition feeds around 3-4 weeks of age to stimulate rumen microflora development.
Gradual introduction helps prepare the digestive system for solid feeds.

Calf Housing Conditions

Proper housing protects calves from environmental stressors and diseases.
Adequate housing is vital for calf growth, health, and development.

Characteristics of Milk Replacer

Milk Replacer is a powdered milk formula mixed with warm water.
It is used after the initial colostrum and fresh milk feeding to provide balanced nutrition.

Calf Feeding - The '3-2-1 Rule'

The '3-2-1 Rule' indicates that calves should receive 3 quarts of colostrum within 2 hours of birth.
This approach ensures timely nutrient absorption essential for survival and health.

Culling Factors for Older Cows

Older cows should be culled based on declining milk yield, health problems, or age.
Replacing them with younger heifers maintains herd productivity.

Grading Up in Dairy Herds

Grading up improves the genetic quality of dairy herds.
It involves replacing lower yielding cows with higher yielding heifers for enhanced production.

Bovine Viral Diarrhoea (BVD)

BVD is a viral infection that significantly impacts calf management.
Affected animals must be identified and culled to prevent the spread within the herd.

Body Condition Score (BCS) for Heifers

Target Body Condition Score (BCS) for heifers at mating is 3.25.
Proper condition is vital for reproductive success.

Mating Weight for Heifers

Heifers should reach a target weight range of 300-330 kg by mating.
Adequate weight ensures optimal reproductive health.

Live Weight Gain for Replacement Heifers

Replacement heifers should achieve a appropriate daily live weight gain (LWG) for development, though specific target figures weren't provided.
