We describe the occurrence of dystocia and stillbirths in Brangus Aberdeen Angus cows heifers within context mineral deficiencies a beef farm located Buenos Aires province, Argentina. Water, forage, blood samples were collected for chemical, serology, quantification, respectively. Birth weight, sex presentation calves monitored at birth, calving ease was evaluated. A stillborn female examined postmortem. The subsequent recorded 6.11% (32 out 523) dams with subclinical hypomagnesemia. During...
This study investigates the newborn thermoregulatory responses to cold and performance of calves fed different colostrum volumes. Thirty Holstein were blocked by birth body weight (BW; 39.4 ± 6.5 kg) high-quality volumes: 10%, 15%, or 20% BW, which was split at 2 8 h after birth. At 24 life, placed in a chamber 10 °C for 150 min. Skin rectal temperature (RT), heart respiratory rate, shivering measured every 15 Blood samples taken 30 After challenge, housed ambient (26.8 5.9 °C), with free...
Oxidative stress may affect new born calves due to high suffered around birth. We hypothesized that maternal supplementation with micronutrients and vitamins in late gestation enhance the neonatal calf’s antioxidant system, decreasing occurrence duration of diarrhea, improving growth from birth through weaning. To test this hypothesis, 80 multiparous cows were cluster-assigned treatment groups. Treated group (TG) received mineral vitamin while control (CG) saline solution. Feed intake fecal...
ABSTRACTThis study aimed to evaluate performance, gut health and metabolic changes in dairy calves receiving milk replacer supplemented with lysine methionine 0.6% or 1% AminoGut (10% Glutamate 10% Glutamine). Forty-five Holstein were blocked distributed the treatments: (1) Control: no supplementation; (2) Lys, Met, 0.6%; (3) 1%. Animals individually housed, free access water concentrate. Milk (6 L/d) was fed until eighth week of life. Feed intake faecal score monitored daily. Calves...

The objective of this study was to evaluate passive immunity transfer, health, performance, and metabolism Holstein calves fed colostrum supplement associated with medium-quality colostrum. After birth, were blocked according birth weight date distributed into the following treatments: high-quality (> 50 mg Ig/mL; n = 15; 150 g kg−1 BW; positive control group); (30-40 14; BW), BW) + (15 mL) given Colostrum within first 12 h life in two meals by nipple bottle, replacer administered a blister...
This study aimed to evaluate the performance and metabolic changes in dairy calves supplemented with lysine methionine milk replacer (MR) or starter concentrate (SC). Male Holstein (n = 45) were blocked distributed Control without supplementation (1) and; Lysine Methionine achieve an intake of 17 5.3 g/d SC (2) MR (3). was fed (6 L/d) until 8th week life when weaning occurred. Calves followed 10th age. Feed measured daily. Weight body measurements registered weekly. Blood samples collected...
This study aimed to evaluate the performance and metabolic changes in dairy calves fed a step-up/step-down program supplemented with lysine methionine milk replacer (MR) or starter concentrate (SC). Male Holstein (n = 45) were blocked distributed control without supplementation (1) SC achieve an intake of 17 5.3 g/d, respectively (2), MR same daily (3). was 4 L/d until 2nd week, 8 from 3rd 6th 7th 8th when weaned. The followed 10th week age. Feed measured daily. Weight body measurements...
Due to the synepitheliochorial placental structure, bovines show no maternal antibody flow from mother fetus during pregnancy, resulting in an agammaglobulemic newborn [...]
The use of milk replacer instead whole may be an economical alternative to calf-rearing systems. However, together with the volume fed, its composition is critical for high performance, especially regarding origin protein. Two replacers different protein content were evaluated see effect on performance calves. Thirty-three Holstein calves distributed in treatments: (1) High Volume and Low Protein (HV/LP), control group: 8 liters, 19.5% CP; (2) (HV/HP): 23.7% CP (3) (LV/HP): 6 CP. Calves...
Regardless of the causative agent, diarrhea results in large loss water and electrolytes, which leads to reduced performance mortality. The aim this study was evaluate oral rehydration solutions order determine most effective restoring electrolytes while maintaining animal performance. Forty two calves (14 per treatment) were distributed one three treatments (1) Common solution (dextrose, sodium bicarbonate chloride; 507±2 mOsm), (2) Glutellac® (sodium acetate, glucose potassium 665±1 mOsm);...
RESUMO Foram utilizados 24 bezerros que receberam 4L/dia de sucedâneo, além livre acesso a água e concentrado até 8a semana. Os animais foram distribuídos em delineamento blocos casualizados, dois tratamentos: 1) Controle: sem suplementação probiótico; 2) Suplementação 2g/d Bacillus subtilis licheniformis via sucedâneo lácteo. Semanalmente os pesados aferidas as medidas corporais; também realizadas colheitas sangue para determinação glicose, proteína total, ureia albumina, hematócrito....
Colostrum is an important immunity supply that protects calves against infectious diseases. Additionally, colostrum excellent energy source for thermogenesis the newborn calf. However, amount of required to promote heat not well established. The objective this study was evaluate thermoregulation, performance, and blood metabolites in fed different amounts colostrum. Thirty Holstein male were blocked by birth weight (BW) a randomized experimental design high-quality 3 volumes: 10, 15, 20% BW....
The aim of this study was to evaluate the transfer passive immunity, performance, and health Holstein calves fed colostrum supplement associated with a medium-quality colostrum. After birth, 44 newborn male were blocked according birth weight (BW) date distributed in following treatments: 1) 15% BW high-quality (70.6 mg immunoglobulin/mL; n = 15; 39.2 kg), 2) (42.7 14; 38.0 3) (41.7 39.1 kg) + (Feedtech Colostrum Supplement; DeLaval, São Paulo, Brazil). within first 12 h life two meals.
