ANPROD PREFINALS

Animal Production: Understanding principles and practices of animal husbandry and how they affect productivity and animal welfare.

Vet perspective on animal behavior: Will Rogers quote highlights the importance of understanding animal behavior in veterinary medicine, emphasizing that a successful vet must not only know disease treatments but also animal instincts and behaviors to provide comprehensive care.

Definition: The scientific study of animal behavior in their natural habitat, focusing on the ways behavior is shaped by natural selection.
Key Concept: Understanding behaviors without anthropomorphism (attributing human traits to animals), which is critical in accurately interpreting animal actions in various contexts.

Focuses on the interactions between animals and their environments, aiming to understand how these interactions influence the evolutionary adaptations of behaviors.
Seeks to understand how behaviors enhance reproductive success and survival, contributing to the overall fitness of the species.

Encompasses all actions and reactions of animals in response to stimuli, including environmental interactions, which are crucial for survival and reproduction.

Definition: Inherited and instinctive behaviors that do not require learning through experience.
Examples: Nursing behavior in mother animals, survival instincts like fleeing from predators, and mating rituals.

Definition: Behaviors acquired through experience that exhibit flexibility and adaptation.
Description: Learned behaviors develop from trial and error and can be modified based on changing circumstances.

Evolutionary perspective links behavior to reproductive success and fitness, showing how natural selection can favor certain behaviors.
Understanding behaviors aids in animal management and welfare, allowing for better practices in care and handling affected by behavioral science.

Innate behaviors: Allow for quick responses vital in survival situations, requiring no prior learning.
Learned behaviors: Demonstrate adaptability and responsiveness to changing environments, enhancing survival chances in dynamic situations.

Habituation
- Decreased response to repeated stimuli (e.g., baby birds not fearing falling leaves after repeated exposure).
Imprinting
- Irreversible learning occurring during a critical period (e.g., salmon recognizing their birth stream which aids in migration).
Associative Learning
- Connecting behavior with rewards or punishments.
- Operant Conditioning: Learning through trial and error; behaviors are guided by rewards and punishments.
- Classical Conditioning: Linking a neutral stimulus with a significant one (e.g., Pavlov's dogs learning to salivate at the sound of a bell).
Observational Learning
- Learning by mimicking others (e.g., killer whale calves imitating their mothers’ hunting techniques).
Insight Learning
- Reasoning to solve problems or adapt behaviors successfully without prior experience or trial and error approaches.

Fixed-Action Patterns (FAP)
- Innate, preprogrammed responses to stimuli that are often species-specific (e.g., nest building in certain bird species).
Agonistic Behavior
- Involves competitive behaviors such as aggression, defense, and establishment of social hierarchies crucial for survival.

Dominance Hierarchies: Structured social ranking through which animals establish access to resources and mating opportunities.
Roles such as Alpha and Beta within groups, influencing group dynamics and interactions.

Chemical: Utilization of pheromones for triggering behaviors, mating processes, and physiological changes.
Visual: Displays during aggressive encounters or courtship that convey signals and intentions.
Auditory: Long-distance communication mechanisms (e.g., bird songs) for attracting mates and warning others.
Tactile: Greetings through touch (e.g., primate grooming behaviors reinforce social bonds).

Types of Production Systems:
- Extensive: Low input and low efficiency; heavily reliant on natural grazing and resources available in the environment.
- Intensive: Characterized by high input and high efficiency; productivity maximized through resource management, including feed and housing.
- Semi-Intensive: A hybrid approach combining elements of extensive and intensive practices.

Essential to consider climatic variations and human influences on animal production including practices that ensure environmental protection and resource conservation.

Provides essential protection, minimizes energy loss, ensures comfort, and promotes health standards for animals during production phases.

Factors to consider: Soil quality, water availability, protection from environmental hazards, accessibility to markets, to promote optimal animal productivity.

Profitability Analysis: Evaluates cost-efficiency and helps identify areas for resource management improvement leading to increased profitability.
Cost Structures:
- Explicit vs. Implicit Costs:
  - Explicit costs: Direct financial expenditures like feed or veterinary care.
  - Implicit costs: Opportunity costs affecting resources that aren’t directly paid out of pocket but must be considered in budgeting.
- Variable vs. Fixed Costs:
  - Variable Costs: Costs that change with production levels (e.g., feed costs depending on the number of animals).
  - Fixed Costs: Costs that remain constant irrespective of production levels (e.g., land lease payments).

Essential for effective budgeting and financial management include Average Cost, Total Cost, and Marginal Cost calculations.

Identifying Disease Causes: Understanding factors such as host susceptibility, infectious agents, nutritional status, and environmental conditions that contribute to disease.
Preventive Strategies: Encompasses proper nutrition, optimized housing logistics, regular veterinary care, and stringent sanitation protocols that are crucial for maintaining overall animal health.
