Veal Calf Waste Production and Composition
Applied Engineering in Agriculture, 1989Volume and composition of fresh waste were deter-mined from 12 newborn male Holstein veal calves during a 14-week trial. Total waste (feces and urine) was collected daily from beneath the slatted floors of each individual wooden calf pen, weighed, and a subsample obtained for analysis. Daily composite aliquots of fresh waste from all calves were placed

American Association of Bovine Practitioners Conference Proceedings, 1990
The use of records in a production medicine program can vary from the simple to the complex. Regardless of the degree of sophistication in the system, records should accurately document events occurring in the herd. Historians and politicians frequently use the phrase.

Biosecurity in dairy calf production: A scoping review
Preventive Veterinary MedicineInfectious diseases pose a persistent threat across all stages of the dairy production chain, with calf rearing being particularly vulnerable due to the calves' immature immune systems. Effective biosecurity measures are crucial in mitigating the risk of pathogen introduction and spread among calves. The recent influenza outbreak in U.S.

The production of calf pneumonia with Escherichia coli and a bovine picornavirus
Journal of Comparative Pathology, 1971Six calves were inoculated intratracheally with tissue culture fluid containing bovine picornavirus 63 355, and one day later with a broth culture of Escherichia coli. All 6 calves developed a purulent bronchopneumonia. One of 5 calves inoculated with sterile tissue culture fluid and then with E.

Pathways of Adenosine Triphosphate Production by Calf Lens Homogenates
Nature, 1962IN previous work we investigated the phosphorylations occurring in homogenates of various zones of the crystalline lens of a calf incubated with glucose-6-phosphate1. The transformation of adenosine diphosphate (ADP) into adenosine triphosphate (ATP) was measured by isolation of the nucleotides by column chromatography ‘Dowex 1 × 8’ 200–400 mesh ...

Effects of Energy and Lasalocid on Productivity of First-Calf Heifers
Journal of Animal Science, 1989One hundred forty-three crossbred, fall-calving first-calf heifers were used to determine the effects of two levels of energy and two levels of lasalocid on cow-calf productivity. Diets fed for approximately 110 d prepartum were calculated to provide a daily intake of 15.3 (LE) or 18.0 (HE) Mcal ME; diets fed for approximately 130 d postpartum were ...

Cerebral ammonia production during hypoglycaemia in the newborn calf
Experientia, 1979The effect of insulin hypoglycaemia on cerebral blood flow, and cerebral metabolic rates of glucose, oxygen and ammonia was investigated in the unanaesthetized newborn calf. A net loss of ammonia from the brain occurred during hypoglycaemia, and was greater in convulsing than in comatose animals.

Production records in cow-calf operations
American Association of Bovine Practitioners Conference Proceedings, 2013Production records can be used to measure herd performance. They identify potential areas for improvement and lead to management decisions to address these areas. These decisions are then evaluated by monitoring performance with production records, continuing the cycle. A variety of software programs can be used to manage production records ...

Preventive Veterinary Medicine, 1995
Abstract A random sample of 651 assumed-pregnant cows was drawn from 26 randomly selected beef herds in Northwestern Quebec, Canada. The cows were followed with their calves (n = 568) for one production period. Data were collected on calving conditions, calf mortalities, and the presence of diarrhea and pneumonia in calves during the first 2 weeks of

Effects of twinning on dystocia, calf survival, calf growth, carcass traits, and cow productivity.
Journal of Animal Science, 1996This paper reports results from a long-term experiment with a primary objective to increase twinning rate in cattle at the Roman L. Hruska U.S. Meat Animal Research Center. Survival of singles was 13% higher (P < .01) than that of twins at birth, and the difference in survival in favor of singles was of similar magnitude at 72 h (12.9%, P < .01), 150 d
