  • Level 2 core unit in the Agricultural Science major sequence
  • The area of knowledge for this unit is Life and Health Sciences
  • Category B broadening unit for students
Content
The focus of this unit is the matching of livestock energy demand to supply of feed, particularly forage, within Australian agricultural systems. Pasture production is first focused upon with an emphasis on the ecology of the major pasture legumes and grasses, especially in a Mediterranean climate, as is typical of Western Australia. Breeding of annual pasture legumes is examined. The ruminant digestive system and reproductive cycle are explored along with the factors that determine diet, feed quality and feed intake. Current challenges and innovations in livestock systems, including in the rangelands of Western Australia, are explored in lectures and through visiting the UWA Future Farm and Shenton Park Research Station (e.g. saltland pastures, perennial native shrubs, novel annual pasture legumes, legume breeding, oestrogenic pastures and low stress livestock handling). Laboratories are used to explore key concepts in more detail and the skills needed to design experiments and collect and explore data using Excel and the statistical package R are emphasised throughout the unit.
Outcomes
Students are able to (1) list the key characteristics of the current common pasture and livestock species grown in Australia; (2) demonstrate understanding of the ruminant digestive system and how livestock energy demand can be matched to feed type and availability; (3) communicate the key factors influencing the economic viability of grazing systems in Western Australia; (4) demonstrate a capacity for broad and critical thinking in relation to how pasture and livestock systems in Western Australia could implement innovative solutions to current economic and environmental challenges; (5) demonstrate understanding of the basic principles of experimental design, data collection and data exploration for pasture and livestock experiments; and (6) build a simple computer model of an agricultural system using Excel and the R statistical package to predict outcomes from various scenarios.
Assessment
Indicative assessments in this unit are as follows: (1) project; (2) laboratory reports; and (3) examination. Further information is available in the unit outline.

Supplementary assessment is not available in this unit except in the case of a bachelor's pass degree student who has obtained a mark of 45 to 49 overall and is currently enrolled in this unit, and it is the only remaining unit that the student must pass in order to complete their course.

  • The availability of units in Semester 1, 2, etc. was correct at the time of publication but may be subject to change.
  • All students are responsible for identifying when they need assistance to improve their academic learning, research, English language and numeracy skills; seeking out the services and resources available to help them; and applying what they learn. Students are encouraged to register for free online support through GETSmart; to help themselves to the extensive range of resources on UWA's STUDYSmarter website; and to participate in WRITESmart and (ma+hs)Smart drop-ins and workshops.
  • Books and other material wherever listed may be subject to change. Book lists relating to 'Preliminary reading', 'Recommended reading' and 'Textbooks' are, in most cases, available via the Booktopia Textbook Finder, which has the functionality to search by course code, course, ISBN and title, and may also be posted or available at the appropriate school's administrative offices. Where texts are listed in the unit description above, an asterisk (*) indicates that the book is available in paperback.
