Lesson 2 • Major Livestock Species and Breeds

Surveys cattle, swine, poultry, sheep, goats, and aquaculture species by production purpose. Introduces breed classification and selection criteria for specific environments.

Lesson 3 • Animal Behavior and Ethology

Examines natural behavioral patterns, social hierarchies, and stress indicators in livestock. Applies ethological knowledge to housing design and handling protocols.

Lesson 4 • Livestock Production Systems Overview

Compares extensive, intensive, semi-intensive, and organic production models by resource use and output. Provides a framework for evaluating system suitability across climates and markets.

Lesson 1 • Ration Formulation Techniques

Applies Pearson square, linear programming, and software tools to balance rations. Integrates nutrient requirements tables with ingredient composition data.

Lesson 2 • Principles of Animal Nutrition

Introduces macronutrients, micronutrients, water, and energy metabolism in livestock. Establishes nutritional vocabulary used throughout feed formulation and ration balancing.

Lesson 3 • Feed Ingredients and Composition

Analyzes energy feeds, protein sources, forages, and feed additives by nutritional profile. Prepares students to select cost-effective ingredients meeting production targets.

Lesson 4 • Feeding Programs Across Production Stages

Designs phase-feeding strategies for growth, gestation, lactation, and finishing stages. Connects feeding programs to production performance benchmarks and economic targets.

Lesson 1 • Mating Systems and Crossbreeding

Compares purebred, crossbreeding, and rotational mating systems for heterosis and breed complementarity. Guides design of mating programs suited to production system goals.

Lesson 2 • Breeding Objectives and Selection

Defines economic breeding values, selection indices, and trait prioritization for production goals. Teaches calculation and interpretation of estimated breeding values.

Lesson 3 • Fundamentals of Animal Genetics

Reviews Mendelian inheritance, quantitative genetics, and gene expression in livestock. Provides the genetic foundation required for understanding heritability and selection response.

Lesson 4 • Genomic Selection and Modern Tools

Introduces SNP genotyping, genomic estimated breeding values, and marker-assisted selection. Evaluates practical application of genomic tools in commercial breeding programs.

Lesson 1 • Parturition and Neonatal Care

Manages normal and dystocia deliveries, placental expulsion, and immediate neonatal care. Reduces perinatal mortality through timely intervention and colostrum management.

Lesson 2 • Reproductive Physiology by Species

Details estrous cycles, gestation lengths, and hormonal regulation in cattle, swine, sheep, and poultry. Provides the physiological basis for timing reproductive interventions.

Lesson 3 • Reproductive Efficiency Metrics and Improvement

Calculates conception rate, calving interval, farrowing rate, and days open as herd KPIs. Designs corrective programs targeting nutrition, health, and management deficiencies.

Lesson 4 • Pregnancy Diagnosis and Monitoring

Applies rectal palpation, ultrasonography, and hormonal assays for pregnancy confirmation. Connects early diagnosis to management decisions that reduce non-productive days.

Lesson 1 • Biosecurity Program Design

Builds farm-level biosecurity plans covering entry control, sanitation, and movement protocols. Applies risk assessment to prioritize biosecurity investments by production system.

Lesson 2 • Major Infectious Diseases by Species

Surveys bacterial, viral, parasitic, and fungal diseases of cattle, swine, poultry, and small ruminants. Emphasizes clinical signs, transmission routes, and economic impact.

Lesson 3 • Principles of Animal Health

Defines health, disease, and immunity in the context of production animal management. Establishes the host-pathogen-environment triad as the basis for disease control strategies.

Lesson 4 • Disease Surveillance and Outbreak Response

Implements passive and active surveillance systems and outbreak investigation protocols. Prepares students to coordinate with veterinary authorities during notifiable disease events.

Lesson 1 • Housing Systems by Species

Compares free-stall, tie-stall, deep-litter, cage, and pen systems for cattle, swine, and poultry. Evaluates each system against welfare, productivity, and cost criteria.

Lesson 2 • Animal Welfare Standards in Housing

Applies the Five Freedoms framework and welfare audit protocols to housing evaluation. Prepares students to identify and correct welfare deficiencies in existing facilities.

Lesson 3 • Principles of Livestock Housing Design

Applies thermal comfort zones, space allowances, and structural requirements to housing design. Links facility design to animal performance, health, and labor efficiency.

Lesson 4 • Ventilation and Microclimate Control

Designs natural and mechanical ventilation systems to control temperature, humidity, and air quality. Addresses heat stress mitigation and cold weather management strategies.

Lesson 1 • Small Ruminant and Aquaculture Production

Covers sheep, goat, and fish production systems with species-specific performance benchmarks. Addresses niche market positioning and value-added product opportunities.

Lesson 2 • Beef Cattle Production Systems

Manages cow-calf, stocker, and feedlot phases from weaning to slaughter weight targets. Applies growth modeling and feed conversion benchmarks to optimize profitability.

Lesson 3 • Dairy Cattle Production Management

Optimizes milk yield, composition, and cow longevity through transition cow and lactation management. Integrates somatic cell count, reproduction, and culling decisions into herd strategy.

Lesson 4 • Swine Production Systems

Manages farrow-to-finish, farrow-to-wean, and wean-to-finish production flows. Targets pigs weaned per sow per year and feed conversion ratio as primary KPIs.

Lesson 1 • Supply Chain and Market Access

Maps livestock supply chains from farm to processor and retailer, identifying value capture points. Evaluates direct marketing, contract production, and cooperative selling strategies.

Lesson 2 • Livestock Enterprise Budgeting

Constructs enterprise budgets separating fixed and variable costs, revenues, and break-even points. Applies sensitivity analysis to evaluate risk under changing input and output prices.

Lesson 3 • Strategic Farm Business Planning

Integrates production, financial, environmental, and human resource goals into a five-year farm plan. Applies SWOT analysis and scenario planning to guide strategic investment decisions.

Lesson 4 • Key Performance Indicators and Benchmarking

Selects and tracks production, financial, and welfare KPIs against industry benchmarks. Uses benchmarking data to identify performance gaps and prioritize improvement actions.
