Animal Production and Management
Core concepts
Animal production depends on genetics, nutrition, health, welfare and environment, and the producer's job is to convert feed into product efficiently. Understand feed intake and digestibility, metabolisable energy and protein, the difference between maintenance and production requirements, and how feed conversion ratio and average daily gain measure performance. Know the ruminant digestive system (rumen fermentation, microbial protein, rumination) and why ruminants can use fibrous pasture while monogastrics cannot.
Management
Be able to discuss breeding objectives (estimated breeding values, heritability, selection for growth versus fertility versus carcass quality), reproductive management (joining, gestation length, condition score, weaning), animal health (biosecurity, vaccination, parasites, notifiable disease reporting), welfare (the five domains, low-stress handling) and grazing management (stocking rate, rotation, rest periods, ground cover).
Traps
- Confusing stocking rate (animals per hectare) with stocking density (animals per unit area at a moment).
- Treating feed conversion ratio as lower-is-better confusion - lower FCR is more efficient.
- Assuming high growth rate always equals high profit; feed cost and market specification matter.
- Ignoring condition score as a predictor of fertility.
Rule of thumb
Profit per head is not profit per hectare. Compare enterprises on gross margin per hectare and per dry sheep equivalent, and remember that in a pasture system, ground cover above about 70% protects soil and sustains pasture recovery.
