Question Title

* 2. Based on Canadian Cow-Calf Survey data presented in the webinar, what is the average total calf loss from birth to weaning in mature cows across Canada?

Approximately 2%

Approximately 3%

Just under 5%

Greater than 8%

Question Title

* 3. Which benchmark reflects top-performing Western Canadian herds (top 25%) for calf loss within the first 24 hours of life?

Less than 3% for cows and heifers

Less than 1% for both cows and heifers

Less than 2% for cows only

Less than 0.5% for heifers only

Question Title

* 4. Which of the following is considered a major non-infectious cause of stillbirth in beef cattle?

Copper deficiency

Poor biosecurity

Dystocia

Heat stress

Question Title

* 5. When investigating abortion or stillbirth cases, which combination of samples provides the best chance of reaching a diagnosis?

Fetus and placenta, submitted fresh

Placenta alone

Fetus alone, regardless of condition

Blood samples from the dam only

Question Title

* 6. Which statement best describes the concept of fetal programming as discussed in the webinar?

Calves compensate fully for poor in-utero conditions if born at a normal weight

Stress during pregnancy can influence lifelong metabolism, immunity, and reproduction

Fetal programming only affects carcass quality

Effects are limited to the neonatal period

Question Title

* 7. Which nutrient deficiencies were highlighted as being more common during drought conditions in Western Canada?

Zinc and selenium

Calcium and phosphorus

Vitamin A and vitamin E

Iron and iodine

Question Title

* 8. Which of the following physiologic consequences may occur in calves following dystocia?

Hyperglycemia and alkalosis

Increased colostrum absorption

Accelerated immune system maturation

Hypoxia, metabolic acidosis, and trauma

Question Title

* 9. Why is timing of colostrum intake critical for newborn calves?

Antibodies are absorbed efficiently for several days

Intestinal absorption of antibodies declines rapidly after birth

Colostrum primarily provides hydration rather than immunity

Passive transfer is unaffected by hypothermia

Question Title

* 10. Which serum total protein value indicates successful passive transfer in a calf aged 2–7 days?

≥ 4.5 g/dL

≥ 5.0 g/dL

≥ 5.5 g/dL

≥ 6.5 g/dL

Question Title

* 11. Which statement best reflects the role of vaccination programs in reducing calf losses?

Vaccines can reduce adult disease, reproductive loss, and neonatal disease when appropriately timed

Vaccination primarily protects calves directly in utero

All herds should follow an identical vaccination protocol

Modified-live vaccines are always safe for use in naïve pregnant cows
