Effect of barley and oats on feed intake, live weight gain and some carcass characteristics of fattening lambs

The influence of whole, crushed and ground barley and oats on intake, performance and carcass characteristics of lambs was examined. A comparison of diets was conducted with individually-fed male and female lambs in six groups. The study was repeated in three successive years (1995–1997) using the s...

Description
Summary:The influence of whole, crushed and ground barley and oats on intake, performance and carcass characteristics of lambs was examined. A comparison of diets was conducted with individually-fed male and female lambs in six groups. The study was repeated in three successive years (1995–1997) using the same experimental design. A total of 192 lambs of a mean initial age of 74 days (SD 13.0) and live weight 20.6kg (SD 4.54) were daily fed their respective concentrates, 72g dry matter (DM)/kg metabolic live weight (kgW0.75), for 98 days from weaning to slaughter. Hay was provided ad libitum. The lambs adapted more quickly to diets containing barley than to those containing oats. Compared to oats, the total daily DM intake was higher on barley (1162 vs. 990g DM/lamb, 89 vs. 78g DM/kgW0.75, P
