Feed conversion efficiency does not negatively affect young sheep and ewe performance. (Original Research article).

ABSTRACT.- Introduction: Improving the feed efficiency (FE) in ruminants offers significant potential for optimizing the use of natural feed resource while simultaneouslyenhancing food and wool production. However, selecting for FE and high productivity may negatively impact the robustness traits, s...

Achoimre:ABSTRACT.- Introduction: Improving the feed efficiency (FE) in ruminants offers significant potential for optimizing the use of natural feed resource while simultaneouslyenhancing food and wool production. However, selecting for FE and high productivity may negatively impact the robustness traits, such as reproduction, health, and fat deposition, indicating potential antagonisms. This study evaluates the relationship between residual feed intake (RFI) and the productivity of yearling and adult ewes in extensive outdoor pastoral systems of three breeds. © 2024 De Barbieri, Navajas, Ramos, Ferreira, Velazco and Ciappesoni.
