The objective of the present study was to examine the effects of replacing wheat grain with two physical forms with corn on starter intake, average daily gain (ADG), feed efficiency, rumen pH, weaning weight, skeletal growth, and blood parameters of neonatal dairy calves. For this purpose, thirty two male of Holstein dairy calves (n=8 calves per treatment) were used in a completely randomized design. At d 3 of age, individually housed calves were randomly allocated to different treatments consisting of: starter with 60 % ground corn (GC), starter with 60 % whole corn (WC), starter containing 30 % ground corn plus 30 % ground wheat (GCGW) or a starter containing 30 % ground corn with 30 % whole wheat (GCWW). Starter intake, growth and blood parameters were monitored during pre-weaning (d 1 to 52) and post-weaning (d 52 to 70) periods. The starters were formulated to be equal in CP and energy. Calves received milk in trial fixed and equal to 10% of BW/D (half in the morning and half in the evening). After birth, all calves were fed enough amounts of colostrums daily for the first 3 d. All calves was weaned 52 d. Calves received every day feed and were weighed per 10 d before the feeding and then bleed blood samples of calves in age 30, 40, 50, 60 and 70 d. Data from trial were analyzed using SAS statistical software and the MIXED procedure as a completely randomized design, and initial body weight was considered as a quvariate variable. The data show that daily starter intake of GCWW group significantly was higher in comparison to other groups in post-weaning period. Calves fed whole wheat had significantly greater ADG comparison to other groups in total experiment. The data in pre weaning show that Average daily gain of GCWW group was significantly greater compared with WC group (p= 0.03). At post weaning, average daily gain was greatest in calves fed GCWW and followed by WC group, but GCWW group significantly had a greater ADG compared with calves fed GC and GCGW groups (1.063 kg Vs 0.736 and 0.617, respectively). There were no differences at pre weaning in body length, hip width, hip height and wither height among the treatments, but differences were significant in heart girth and body girth. At post weaning, some of body measurements (body length, hip height, hip width, heart girth, and wither height) were the greatest in calves fed GCWW diet, however WC group had greater body girth in comparison to other groups. Feed efficiency in calves fed GCWW diets was only significantly higher in compared to GCGW group (p=0.04), but not with others. Blood glucose reduced with age in calves, however blood BUN, BHBA, Albumin, and Total protein increased with time (p 0.01). Comparing the fecal score showed that, no difference were observed between treatments.In Conclusion, results of current study showed that feeding starters with whole wheat and ground corn improve performance of new born dairy calves in comparison to GCGW, WC and GC diets.
