Extract

Safflower meal proteins are extensively degraded in the rumen. Attempts to decrease the degradability of feedstuffs proteins have involved treatment with heat, formaldehyde, tannic acid, acetic acid, xylose, and microwave (Sadeghi et al., 2006). To our knowledge, no information is available concerning effects of gamma irradiation on ruminal protein degradation and type of safflower meal proteins that leave the rumen undegraded. The objectives of this study were to investigate effects of gamma irradiation on ruminal degradability and intestinal digestibility of safflower meal crude protein, and to monitor fate of true proteins of safflower meal in the rumen by using SDS-PAGE methodology.
