ABSTRACT
Tabatabaei SN, Taheri A., Effect of whey powder on performance and digestibility
in Holstein calves, Onl J Vet Res., 21(7):393-399, 2017. Groups of ten 7 day old
Holstein calves each were fed 5, 10 and 20% whey powder in starter basal diet.
Controls were fed basal diet. Calves were weighed at 1, 15, 30, 45 and 60 days.
Feed intake was measured daily. Samples of concentrate, hay and feces dry
matter (DM), ash, crude protein, digestible protein, crude fat, neutral
detergent fiber (NDF) were determined. There were no significant effects on
fecal consistency or incidence of diarrhea. Compared with basal diet controls,
DM, ash, crude protein, digestible protein, crude fat and NDF increased in
calves fed whey supplement (P≤0.05) with highest digestibility occurring
in those given 20% whey powder.
