Calves are born with a mostly inadequate essential amino acid (EAA) status. Studies were designed to test the hypothesis that delaying the intake of the first colostrum for 24 h, besides its early effects, also has late effects on plasma free amino acid levels and on the protein status. There were marked and rapid elevations (within 2 h) of plasma levels of various amino acids, and especially of EAA, after the intake of the first colostrum, whereas changes after the intake of mature milk on day 28 of life were mostly absent or concentrations even decreased. The EAA and non-essential amino acid (NEAA) status was rapidly normalized after intake of the first colostrum, but normal plasma levels of some amino acids were also reached during the first 24 h of life even when the first meal was withheld. Delaying colostrum intake had only transient effects on EAA and NEAA (except hydroxyproline), in contrast to its effects on plasma immunoglobulin G and total protein levels.

“…The respiratory exchange ratio values (RQ) previously determined by Vermorel et al [46] for newborn calves were used for calculations: RQ = 0.80 for blood gas analyses performed before 12 hours old and RQ = 0.76 at 18 and 24 hours old. The analyser was calibrated every three hours with a two-point calibration using certified gas mixtures for oxygen and carbon dioxide partial pressures.…”

Sternal recumbency or suspension by the hind legs immediately after delivery improves respiratory and metabolic adaptation to extra uterine life in newborn calves delivered by caesarean section

-The aim of this study was to evaluate the effect of body positioning immediately after delivery on respiratory and metabolic adaptation to extra-uterine life in newborn calves. One hundred and one Belgian White and Blue calves were delivered at term by an elective caesarean section and were assigned into three categories according to the body position imposed immediately after umbilical cord rupture: 71 calves were placed in lateral recumbency; 16 calves were placed in sternal recumbency and 14 calves were suspended by the hind legs for less than 90 seconds (75 ± 5 s). Following this initial body position, the calves were allowed to move without restraint. They were examined at birth, 5, 15, 30, 45 and 60 minutes, and 2, 3, 6, 12 and 24 hours after birth by the following measurements: physical examination, heart rate, arterial blood gas analysis, pulmonary function tests using the esophageal balloon catheter technique, arterial and venous blood acid-base balance analysis, rectal temperature, jugular venous blood sampling for the determination of blood glucose, plasma lactate and serum cortisol concentrations, haematologic variables and passive immune transfer variables. Body positioning immediately after delivery clearly influenced respiratory and metabolic adaptation to extra-uterine life in term calves delivered by an elective caesarean section. Systematic sternal recumbency and suspension by the hind legs for less than 90 seconds immediately after umbilical cord rupture had a positive functional impact on postnatal pulmonary mechanics and gas exchange and on postnatal correction of mixed acidosis present at birth, contributing in turn to an enhanced passive immune transfer. These two body positions should be encouraged to improve adaptation at birth in healthy term calves delivered by an elective caesarean section. Evaluation of possible side-effects is required before application in severely asphyxiated calves. Résumé -Confiner le veau en décubitus sternal ou le suspendre par les membres postérieurs à la naissance améliore son adaptation respiratoire et métabolique à la vie extra-utérine. L'objectif de cette étude était d'évaluer l'effet du décubitus sternal ou de la suspension systématique par les membres postérieurs immédiatement à la naissance sur l'adaptation respiratoire et métabolique chez le veau nouveau-né sain. Cent et un veaux de race Blanc-Bleu Belge à terme nés par césarienne ont été répartis en trois catégories selon la position dans laquelle ils ont été délibérément placés immédiate-ment après la rupture du cordon ombilical. La première catégorie comprend les veaux placés en décu-bitus latéral (n = 71) ; la seconde, ceux placés en décubitus sternal (n = 16) ; et la troisième, les veaux suspendus par les membres postérieurs pendant moins d'une minute trente secondes (75 ± 5 s) (n = 14). Les veaux ont été examinés à la naissance, à l'âge de 5, 15, 30, 45 et 60 minutes, 2, 3, 6, 12 et 24 heures après la naissance au moyen des tests suivants: un examen clinique, une analyse des gaz sangu...

“…In neonatal calves, standing and related spontaneous physical activity may represent an increase in energy expenditure (EE) of up to 46% above lying (Nienaber et al, 1987;Vermorel et al, 1989). In addition, the activity pattern of animals and probably the energy cost of standing (ECS) vary within the day (Toutain et al, 1977).…”

ABSTRACT:An experiment was conducted with and its standard error were lower than values four preruminant calves to measure the energy cost obtained by regression (2,131 cal-kg BW-I-h-l, SE = and the diurnal pattern of physical activity in 862.2, n = 8 ) . The energy cost of standing was highest tethered, fed calves and to determine whether differafter meal times and lowest at night. These variations ences in activity could interfere with the interpretacould reflect the nonuniform activity patterns of calves tion of circadian changes in heat production. Measurewhile standing. The time spent standing per hour ments were carried out in large respiration chambers showed the same variations during the day as the (3,650 L of inner volume), and a computation method energy cost of standing. Noteworthy, the elevated was presented that allowed the calculation of the energy expenditure measured in the 1st h after the energy cost of standing for each standing period. This morning meal was due to activity cost rather than to cost averaged 449 cal.kg BW-l.h-l (SE = 41.6, n = 4 ) .meal thermogenesis. Standardization of diurnal heat It represented a 23 to 27% increase in heat production production profiles to a given activity pattern thus above that measured in the lying state. This estimate seemed to be necessary.
