Abstract

The research trials were carried to evaluate the effect of replacement of corn by parboiled rice meal in the diet of lactating dairy cows. Nine lactating Holstein cows, 80 ± 24 days in milk, 20 kg of milk per day at beginning of the trial were use in a 3 x 3 latin square design. The experimental diets varied in the concentrate and forage composition: forage based on sorghum silage and concentrate based on corn grain cracked (CGC); forage based on sorghum silage and green corn by-product silage and concentrate based on corn grain cracked and parboiled rice meal in equal parts (CGC + PRM) and forage based on sorghum silage and green corn by-product silage and concentrate in which 79.3% of replacement of corn grain cracked for parboiled rice meal (PRM). The replacement of corn by parboiled rice meal didn’t affect the dry mater, crude protein, mineral mater and starch intakes; the diets with parboiled rice meal had hither intakes of NDF, ADF and ether extract.

KEY WORDS: By-product, lipids, lactation period.
