主　　题：Okara Protein Lactating ewe Suckling lamb 

摘      要：Evaluating the feeding value of wet okara as a protein supplement for lactating ewes with twin lambs was the objective. A 4 x 4 Latin square replicated 2 x(4 sheep, 4 treatments, 4 periods per square; 2 squares) was conducted to examine the influence of concentrate mix(okara or not) and type of forage(silage or hay) on ewe milk composition and growth of their lactating lambs. Treatment periods were 14 days(7 days adaptation and 7 days collection). Ewes(55 to 74.8 kg BW) were fed 1 of 4 diets: wheat middling and corn concentrate with mixed grass hay(TSH), okara and corn with mixed grass hay(OSH),soybean and wheat middlings with hay crop silage(TSS), and okara and corn with hay crop silage(OSS).Ewes fed hay diets had lower forage dry matter intakes than ewes fed silage. Intake of okara supplement was higher(P 0.05) with OSH(3.64 kg/d) than with OSS(1.70 kg/d). There was no difference in supplement intake between TSH and TSS. There were no differences among diets for lamb daily gains or in ewe milk compositions among the diets. Okara is an effective source of protein for lactating ewes and their twin lambs.
