Daily milk intake, weekly BW and blood metabolites (total protein, glucose, non-esterified fatty acids and plasma urea nitrogen) were monitored using Angora kids offered ad libitum (AL) or restricted (RES) intakes of acidified milk replacer (AMR) twice daily during an 11 week period. Solid feed was provided ad libitum starting on week 3. All kids were shorn at the end of the experiment and midside samples taken for fiber characteristics. Average daily gain during the experiment was 30% higher for kids fed AL compared with those fed RES (144 vs 112 g/day; P < 0.001). Average daily milk intake was 0.97 L for RES and 1.37 L for AL (P < 0.001). Pre-treatment BW (2.8 ± 0.1 kg) and blood metabolites were similar for both groups. No differences were found in clean fiber production (275 vs 279 g; P < 0.85) or in any other fiber quality characteristics. Plasma concentrations of glucose (84 mg/dl; P > 0.53), NEFA (313 Eq/l) and total protein (60 g/l; P > 0.79) were not different between groups. Plasma urea nitrogen (PUN) concentrations were higher (10.1 vs 8.5 mg/dl; P < 0.01) for the kids in the RES treatment. No detrimental effects of feeding a restricted amount of AMR to Angora kids were noted on mohair production or blood metabolites although ADG was lower. Restricting milk intake may decrease costs of kid rearing by decreasing milk costs.
