Twenty-four Friesland-cross calves were reared artificially in a 22-factorial experimental design for a period of 13 weeks. The two factors and levels investigated were (1) the fat content of the milk replacer, viz. 20,8 per cent (F1) or 12,6 per…
The object of the study was to determine diet combinations consisting of soybean flour, whey powder and colostrum that can be employed in practice to decrease the pre-weaning rearing costs of dairy calves. In a mixture design experiment the soybean…
Five groups of seven Friesian bull calves received different combinations of soybean flour (S), whey powder (W), and preserved colostrum (C). On a dry matter basis, the experimental diets consisted of 20% S, 60% W, and 20% C (Treatment 1);…
Five groups of seven Friesian bull calves received different combinations of soybean flour (5), whey powder 0N), and preserved colostrum (C) until weaning at 30 days of age. A complete diet was available ad lib. from 4 days of age.…
Two trials were conducted to determine the effect of coagulation suppression of milk and milk replacers on apparent digestibility coefficients and body mass-gain of calves. In Experiment 1, two groups of five Holstein bull calves, two to four days of…
Fourteen Holstein calves, two to four days of age, were randomly divided into two groups to determine the effect of abomasal curd suppression on selected blood profiles. Calves received a milk replacer in which casein coagulation either was normal (CM),…
Two groups of eight Friesland bull calves each were used in the trial. Calves received a commercial, coagulable milk replacer in which casein coagulation either was normal (CM treatment), or was prevented by the precipitation of Ca++ with an oxalic…
