AB  - Oleaginous plant by products are widely used to improve ruminant growth performance for high energy or protein composition, however, few article reports the suitable fit amount for oleaginous by products
to the ruminant diets in a large supplementation range. Therefore, this research was conducted to evaluate the effect of Safflower meal (<I>Carthamus tinctorius</I> L., SFM)/Canola seed (<I>Brassica napus</I>, CAS) with sorghum seed in theoretic proportion (0, 25, 50, 75 and 100%, respectively) in a specific concentrate-roughage ratio of (1:1) on in vitro ovine rumen fermentation performance such as the kinetics of gas production, ammonia nitrogen (NH<SUB>3</SUB> -N), pH, methane production (CH<SUB>4</SUB>) and In Vitro Dry Matter Disappearance (IVDMD) of maize stover. The results showed that gas production performance and methane production were significantly decreased but IVDMD and pH were obviously increased with the increasing proportions of both SFM and CAS in concentrated feed. To take a consideration offermentation performance and environment/cost factors, our results suggest that most suitable supplementation dosageof canola seed and safflower meal in concentrated feed are from 25-50 and 25-75%, respectively. However, in practical production of completed feed, the supplementation amount of safflower meal/canola seed also depend on concentrate-roughage ratios.
