چکیده: The aim of present study was to investigate the effect of 2 liquid feeds and 2 protein sources in starter
on the performance and blood metabolite responses of Holstein neonatal calves from birth to 6 wk of age.
Calves (20 males and 20 females) based on sex were randomly assigned to 4 treatments in a 2 × 2 × 2
factorial arrangement, including soybean meal (SBM) and meat and bone meal (MB) with either fermented
colostrum (or fresh milk. Although sex and liquid feed
had no significant effect on feed intake, calves consumed
more feed intake on the diet containing SBM (15 ± 0.2
kg) than MB (13 ± 0.2 kg) during the experimental
period; also, weight gain was affected by both liquid
feed and starter. Liquid feed and starter had significant
effects on calf body size, including pin width, hip
width, withers height, hip height, and stomach size,
but no significant effects were observed on calf body
size between the sexes. Plasma glucose concentration
was not affected by sex, liquid feed, or starter. Plasma
urea nitrogen concentration decreased in the first 3 wk
and then started to increase during the last 3 wk, but it
was only affected by starter and calves receiving SBM
(10.18 mg/dL) had a higher concentration of plasma
urea nitrogen than calves receiving MB (9.6 mg/dL) at
the end of the experiment. Plasma growth hormone and
insulin-like growth factor I concentrations decreased in
all treatment groups from d 0 to the end of the study.
No significant effects were observed on plasma growth
hormone and insulin-like growth factor I concentrations
between the 2 sexes, but they were significantly affected
by both liquid feed and starter. Results of the present
study provide useful information to apply to Holstein
neonatal calves during the first 6 wk of life when liquid
feed and 2 sources of protein in starter are considered.
