Abstract
This study was conducted in the animal farm at college of agriculture and forestry / Mosul university by using three multiparous cross breed friesian cows in the first month of lactation, average body weight 392.3 kg. The cows was placed in an individual pen and fed on three experimental rations using latin square design ( 3 × 3 ) with three period each was lasted 21 days. First ration ( T1 ) was the control consist mainly of barley, wheat bran, yellow corn and soybean meal, second ration ( T2 ) was similar to the control but contained formaldehyde treated soybean meal, while T3 was similar to T2 , but increased in energy content. Results showed that the treatment had no significant effect in milk production which were 8.67 , 7.91 and 8.81 kg/day for T1 , T2, and T3 respectively, although milk production decreased by 9.6 and 11.37 % in T2 as compared T1 and T3, milk fat , protein , lactose , total solids and energy were not affected significantly by dietary treatments, but it was noted that fat percentage increased by 22.5 and 18 % in T2 and T3 as compared with T1. Also, blood parameters were differed between treatment but not significantly.
