Dairy Science Course

Lesson 1 • Milk Composition and Properties

Analyses the chemical and physical components of milk, including fat, protein, lactose, and minerals. It underpins processing and quality chapters.

Lesson 2 • Dairy Cattle Breeds and Selection

Examines major dairy breeds, their production traits, and selection criteria. It connects breed choice to farm productivity goals.

Lesson 3 • Overview of the Dairy Industry

Covers global and domestic dairy production systems, key stakeholders, and market structure. It provides context for all subsequent technical content.

Lesson 4 • Mammary Gland Physiology

Describes mammary gland anatomy, milk synthesis pathways, and lactation cycles. It is essential for understanding milking management and health.

Lesson 1 • Nutrient Requirements of Dairy Cattle

Covers energy, protein, mineral, and vitamin needs across production stages. It directly informs ration formulation in later sections.

Lesson 2 • Forage Production and Storage

Covers silage making, hay production, and forage quality preservation techniques. It ensures a reliable, high-quality feed supply for the herd.

Lesson 3 • Feeding Management Strategies

Addresses total mixed ration delivery, bunk management, and transition cow feeding. It connects ration design to on-farm implementation.

Lesson 4 • Ration Formulation Principles

Applies nutrient requirement data to balance rations using least-cost and software-based methods. It bridges nutrient knowledge to practical feeding decisions.

Lesson 1 • Principles of Preventive Herd Health

Introduces biosecurity, vaccination protocols, and health monitoring frameworks. It establishes a proactive approach to disease management.

Lesson 2 • Reproductive Tract Health

Addresses metritis, retained placenta, and ovarian disorders affecting reproductive efficiency. It connects herd health to reproduction management.

Lesson 3 • Responsible Antimicrobial Use

Covers antimicrobial stewardship, withdrawal times, and record-keeping requirements. It ensures compliance with food safety and residue avoidance standards.

Lesson 4 • Mastitis Prevention and Control

Covers mastitis etiology, detection methods, and control strategies including dry cow therapy. Mastitis is the costliest dairy disease, making this section critical.

Lesson 1 • Pregnancy Diagnosis and Calving Management

Covers rectal palpation, ultrasound, and blood-based pregnancy tests plus calving protocols. It ensures accurate pregnancy records and safe calving outcomes.

Lesson 2 • Artificial Insemination Techniques

Covers semen handling, thawing, and deposition techniques for successful AI. It builds practical skills essential for herd genetic improvement.

Lesson 3 • Estrus Detection Methods

Compares visual observation, activity monitors, and tail paint for detecting estrus. Accurate detection is the foundation of effective breeding programmes.

Lesson 4 • Synchronization and Timed AI Programmes

Explains Ovsynch, Presynch, and Double-Ovsynch protocols and their applications. It enables high submission rates without relying solely on estrus detection.

Lesson 1 • Milking Procedures and Cow Preparation

Covers pre-dip, forestripping, teat drying, and unit attachment protocols. Proper procedure reduces mastitis risk and maximises milk letdown.

Lesson 2 • Milk Quality Troubleshooting

Provides systematic approaches to diagnosing elevated SCC, high bacterial counts, and off-flavours. It connects quality data to corrective management actions.

Lesson 3 • Milking Equipment and Systems

Describes pipeline, parlour, and robotic milking systems and their components. Equipment knowledge is the prerequisite to effective milking management.

Lesson 4 • Raw Milk Quality Parameters

Defines somatic cell count, bacterial count, freezing point, and inhibitor tests. These parameters determine milk acceptance and pricing at the processor.

Lesson 1 • Fermented Dairy Products

Addresses yogurt, cultured buttermilk, sour cream, and kefir production processes. Fermentation extends product diversity and shelf life.

Lesson 2 • Cheese Manufacturing Principles

Covers coagulation, cutting, cooking, pressing, and salting steps for cheese production. Cheese represents the largest volume dairy product category globally.

Lesson 3 • Butter and Dried Dairy Products

Covers cream churning, butter working, spray drying, and powder quality standards. These products enable long-term storage and global trade of dairy solids.

Lesson 4 • Homogenization and Standardization

Explains fat standardization, homogenizer mechanics, and their effects on product texture. These steps determine the physical properties of fluid milk products.

Lesson 1 • Quality Management Systems

Introduces ISO-based quality management, internal auditing, and continuous improvement tools. Systematic quality management reduces defects and customer complaints.

Lesson 2 • Traceability and Recall Management

Covers lot coding, traceability systems, and product recall procedures. Effective traceability limits the scope and cost of food safety incidents.

Lesson 3 • Good Manufacturing Practices

Covers facility design, personnel hygiene, pest control, and equipment maintenance standards. GMPs form the prerequisite foundation for HACCP implementation.

Lesson 4 • Dairy Regulatory Compliance

Surveys milk grading standards, plant licensing, and inspection requirements across the supply chain. Compliance protects market access and consumer safety.

Lesson 1 • Strategic Planning and Farm Growth

Applies SWOT analysis, capital investment appraisal, and succession planning to dairy enterprises. Strategic planning aligns resources with long-term farm goals.

Lesson 2 • Herd Performance Metrics and KPIs

Defines key performance indicators for reproduction, production, and health and links them to profitability. KPI tracking enables data-driven management decisions.

Lesson 3 • Dairy Farm Financial Statements

Covers income statements, balance sheets, and cash flow analysis specific to dairy enterprises. Financial literacy is the foundation of sound business decisions.

Lesson 4 • Milk Pricing and Risk Management

Explains milk pricing formulas, component pricing, and hedging strategies for price risk. Price volatility is a primary financial risk for dairy producers.
