The evaluation of the effect of the different starters on body measurements of dairy calves

The objective of this study was to determine the effect of different starters for calves (including dried whey and protein sources whit low ANFs) on the variability of the birth weight, body weight and body measurements (birth weight, body weight, withers height, hip height, body length, chest depth, chest width, heart girth, cannon bone circumference and hip width). Accordingly, to feeding, calves were divided into four groups ; control (control starter), E1 (starter with added dry whey), E2 (starter whit added protein sources whit low ANFs), and E3 (concentrate whit added dry whey and protein sources whit low ANFs). Calves were individually housed in a boxes with feeders and drinkers. Average birth weight of calves were 41.21±3.22 kg. Based on obtained results it could be concluded that different starters significantly influenced following traits: body weight, withers height, body length and hip width while the variability of other analysed due to different feeding groups were not statistically significant.
