ABSTRACT

Sahin K, Sahin N, Sari M., Digestibility, growth, serum and tissue selenium in lambs ingesting Astragalus spp, Onl J Vet Res., 29 (10): 627-638, 2025. We describe digestibility, growth, serum and tissue selenium in three groups of 6 month lambs each gavaged 0.2, 50, and 52 ppm selenium with Astragalus gummifer or A kurdicus of 70% forage and 30% concentrate daily for 90 days. Five controls were fed hay. In those fed  we observed ataxia, paralysis, hair loss, lacrimation, and cracked hoof walls by 30 days and by 90 days, serum and tissue selenium increased 37 to 90 and 20 to 48 times above controls (P < 0.05)  whereas feed intake and weight gain had declined (P < 0.05) 27 to 29% . The findings suggest Astralagus spp is toxic fed to young lambs.

KEY WORDS: Astragalus spp, Selenium, Digestibility, Growth, Sheep.
