Effect of curd suppression of a calf milk replacer fed at increasing levels on nutrient digestibility and body mass-gain
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 acid-sodium hydroxide buffer (NCM treatment). In both treatments, the daily milk replacer feeding level (percentage of birth mass) was increased fro...
متن کاملUrea recycling contributes to nitrogen retention in calves fed milk replacer and low-protein solid feed.
Urea recycling, with urea originating from catabolism of amino acids and hepatic detoxification of ammonia, is particularly relevant for ruminant animals, in which microbial protein contributes substantially to the metabolizable protein supply. However, the quantitative contribution of urea recycling to protein anabolism in calves during the transition from preruminants (milk-fed calves) to rum...
متن کاملDigestibility and blood parameters in the preruminant calf fed a clotting or a nonclotting milk replacer.
Eight male Holstein calves 7 to 10 d of age were fed a milk replacer containing a skim milk powder subjected to low-temperature drying either with or without addition of an oxalate-NaOH buffer known to prevent curd formation. The calves were used in a completely randomized design to study the effect of milk clotting on digestibility and blood parameters. Plasma glucose and plasma insulin were s...
متن کاملGrowth, Nutrient Utilization and Amino Acid Digestibility of Dairy Calves Fed Milk Replacers Containing Different Amounts of Protein in the Preruminant Period*
This study was designed to examine the effects of different dietary protein levels on growth performance, nutrient utilization, amino acid (AA) digestibility and serum biochemical parameters of preruminant dairy calves. Fifteen healthy new-born calves were randomly allotted to three experimental groups and fed with different milk replacer that contained 18% (LP), 22% (MP) or 26% (HP) of protein...
متن کاملUtilization of Soymilk as Milk Replacer for Calves
An experiment was conducted to study the utilization of soymilk as milk replacer for raising calves. Nine crossbred calves were selected and divided into three groups on the basis of their body weight and genotype. The calves of group A were reared by cow milk, group B reared by strained soymilk and group C reared by unstrained soymilk. It was found that, total body weight gain of group A, B an...
