Quiz 1 Animal Management Flashcards
What are ruminants?
Herbivores with a four-chambered stomach that can digest fibrous plant materials
What is a monogastric?
Animals with a single-chambered stomach typically requiring grain based diets
How much of grain product is fed to animals and how many people could this feed?
1/3-1/2 which could feed 3.5 billion people
What is blue water?
Water in rivers and lakes and groundwater
What is green water?
Water found in plants, the soil and rain
What is more efficient meat or milk?
Milk
What also impacts the efficiency of animals?
Maturity
What are legumes beneficial for?
They counteract depletion of nutrients in soil
What are the four key contributions of livestock production to society?
Food supply, economic value, cultural significance, and ecosystem services.
How do intensive livestock production systems differ from extensive systems?
Intensive systems have high inputs/outputs and are often controlled, while extensive systems use larger areas with lower inputs and rely on natural environments.
What is a mixed livestock production system?
A system that integrates both crops and livestock, where animals contribute to soil fertility, and crops provide feed.
How do different livestock species utilise feed resources?
Ruminants (e.g., cattle, sheep) digest fibrous material like grass, while non-ruminants (e.g., pigs, poultry) require grains.
What are the major resource requirements in livestock production?
Feed, water, and land usage.
Why is waste management important in intensive livestock systems?
To prevent pollution from large amounts of waste and to use manure as fertiliser responsibly.
How can livestock production impact greenhouse gas emissions?
Ruminants produce methane, but feed efficiency improvements and breeding for lower-emission animals help mitigate this.
What are three environmental management practices in livestock production?
Rotational grazing, waste management, and water conservation.
What are dual-purpose livestock production systems?
Systems designed to produce more than one product, such as dairy cows that also provide meat.
What are controlled environments in intensive livestock production?
Systems with regulated temperature, humidity, and light to optimise production, often with automatic feeding and waste management.
What are the infrastructure demands of intensive livestock systems?
Buildings, ventilation, sanitation, feed storage, and biosecurity measures
What are some animal welfare concerns in intensive livestock production systems?
Overcrowding and lack of stimulation, which can lead to stress, despite high production efficiency.
What characterises extensive livestock production systems?
Use of natural pastures, forests, or rangelands, with fewer inputs and more resilience to environmental changes.
What are the potential environmental impacts of extensive livestock production systems?
Overgrazing can cause soil erosion and loss of vegetation, but well-managed systems promote soil health and biodiversity.
Why are husbandry procedures like castration important in the Australian beef cattle industry?
Castration helps prevent indiscriminate breeding, improves management and handling, and reduces aggression. However, it is painful, and different methods cause different types of tissue damage.
What are the purposes of ear tagging and ear notching in beef cattle and what do they involve?
They are used for identification purposes. Ear tagging involves colour-coded tags based on the year of birth, while ear notching involves a unique cut-out pattern in the ear.
