Comparison of Two Conventional Restricted Daily Milk Allowance Methods in Dairy Calf Rearing with Respect to Growth and Behavioural Responses 1. Growth Responses

Authors : Ibrahim Tapki

Abstract: This study was carried out to investigate the differences between two milk feeding methods (allowances) based on 10% of birth weight or 10% of weekly adjusted live weight of dairy calves in respect to growth performance. Twenty Holstein Friesian calves (14 males, 6 females) were allocated into two different milk feeding schedules, one was based on 10% of birth weight (IBW, n = 10) and another was 10% of live weight which was determined on weekly basis (ABW, n = 10), for feeding whole milk during the rearing period. All calves were kept in individual pens located in a semi-open barn for 60 days. Feed intake, live weight, body length, withers height, heart girth, chest depth and rump height and width measurements of calves were determined for both groups. Daily calf starter intake were 490 vs 640 g (p< 0.01), daily hay intake 150 vs 220 g (p< 0.01), daily total feed intake 640 vs 860 g (p< 0.01), daily milk allowance 5.06 vs 3.24 kg (p< 0.01), daily live weight gain 530 vs 515 g (p>0.05), daily body length gain 0.213 vs 0.219 cm (p>0.05), daily withers height gain 0.176 vs 0.164 cm (p>0.05), daily heart girth gain 0.288 vs 0.280 cm (p>0.05), daily chest depth gain 0.119 vs 0.114 cm (p>0.05), daily rump height gain 0.163 vs 0.154 cm (p>0.05) and rump width gain 0.069 vs 0.062 cm (p>0.05) were determined in ABW and IBW calves respectively. Starting time of calf starter intake, hay intake and rumination were 12 vs 9 days (p< 0.01), 13 vs 11 days (p< 0.01) and 14 vs 11 days (p< 0.01) for ABW and IBW calves respectively. In conclusion, milk allowance during calf rearing by criterion of 10% of birth live weight basis encouraged calves better than that of 10% of adjusted live weight basis to compensate their increased nutritional requirements by consuming other foods calf starter and alfalfa hay.
