Secondary Data (Leaving Cert Agricultural Science): Flashcards

Information already collected by researchers/agencies to analyse animal performance and trends

Weight an animal gains per day during a specific period

Efficiency of converting feed into live weight gain

$\frac{\text{Final weight} - \text{Initial weight}}{\text{Days}}$

$\frac{\text{Total feed intake (DM)}}{\text{Live-weight gain}}$

Better efficiency - less feed needed per kg of weight gain

Good nutrition and management practices

Evening higher: 4.2% vs 3.7%

Evening higher: 13.02% vs 12.52%

Fresh weight or dry matter basis
