Growth, Blood Metabolites, and Health of Holstein Calves Fed Milk Replacer Containing Different Amounts of Energy and Protein
This study was conducted to compare the effects of feeding high protein and low energy milk replacer (HPR; CP 25%, ME 3.6 Mcal/kg DM) with low protein and high energy milk replacer (HPR; CP 21%, ME 4.2 Mcal/kg DM) on feed consumption, body weight (BW) gain, health and selected blood metabolites in Holstein calves during the pre-weaning period. At each feeding, each milk replacer (MR) was prepar...
متن کاملEffects of Extruded Flaxseed and Conjugated Linoleic Acid on Growth Performance in Holstein Milk-Fed Calves
The aim of this study was to investigate the effects of extruded flaxseed and conjugated linoleic acid on growth performance, blood parameters in Holstein suckling calves. This experiment was carried out with 30 newborn Holstein calves with an average age of 1-8 days, and about 36±2 kg body weight, with 6 treatments and 5 replications in a completely randomized factorial design (3×2). The treat...
متن کاملEffects of milk replacer composition on growth, body composition, and nutrient excretion in preweaned Holstein heifers.
Twenty-four newborn Holstein heifer calves were fed 1 of 4 milk replacers (MR): control (20% CP, 21% fat; MR fed at 441 g/d); high protein/low fat (HPLF; 28% CP, 20% fat; MR fed at 951 g/d); high protein/high fat (HPHF; 27% CP, 28% fat; MR fed at 951 g/d); and HPHF MR fed at a higher rate (HPHF+; 27% CP, 28% fat; MR fed at 1,431 g/d). Dry calf starter (20% CP, 1.43% fat) composed of ground corn...
متن کاملEffect 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 کاملSerum Protein of Female Holstein Calves Fed Milk through Step-Down and Conventional Methods
The serum proteinograms of 10 female Holstein calves fed milk either through conventional (COV) or step-down (STP) milk feeding methods at different ages were evaluated. Calves fed using the COV method were fed colostrum during the first 24 hours that they stayed with their respective mothers and received transition milk for another 2 days and later, and then milk at four liters/day for 59 days...
