Resumo
The objective of this research was to evaluate the effects of replacing corn grain by citrus pulp on dairy cows
performance. Nine Holstein cows (three cannulated in the rumen), at 80 ± 24 milking days, and daily medium
production of 20 ± 0.58 kg/day were used. Animals were maintained in tie stall with individual feeder and
drinker. Experimental design was a 3 x 3 Latin square. Experiment lasted 21 days, being 14 days of adaptation
and seven of collection. Treatments were 100% corn grain (CG); 50% corn grain and 50% citric pulp (CG-P)
or 100% citrus pulp (P). There were no differences in nutrients (DM, OM, NDF, ADF, CP, starch) ingestion
among diets. The treatment with citrus pulp produced larger proportion of acetate in relation to the others, as
well as larger acetate/propionate ratio. The pH averages ranged between 5.86 and 7.35. The averages of N-NH3
presented larger differences in the times 2 and 3 hours after feeding. There were no differences among the diets
for total 4%-fat corrected milk production, protein, lactose, total dry extract (TDE) and milk urea nitrogen Substituição de fonte de amido por fibra solúvel em detergente neutro na dieta de vacas
