What’s important during this life stage?
- Maintaining the cow’s body condition score (BCS)
- Establishing calf immunity through the consumption of maternal antibodies via quality colostrum
- Reproductive performance in beef cattle
- Poor reproductive rates: This could be the result of nutritional deficiencies, particularly of trace minerals, or disease challenges.
- Forages with high mycotoxin concentrations: Mycotoxins can reduce rumen efficiency in addition to negatively impacting reproduction.
- Low-quality forages: Examining forage quality is key, as forages with poor digestibility or those that are low in protein can lead to nutrient deficiencies without proper supplementation.
- Poor colostrum quality: Colostrum is an important source of maternal antibodies and nutrients, which are essential in promoting proper immune development and growth in the newborn calf.
- Calfhood scours: Scours may be due to failed passive transfer, which is an absence of the transfer of maternal antibodies; it can also be linked to unclean calving areas.
Tips for maximizing health and performance
- Provide proper nutrition.
- Ensure that the cows’ diets are not deficient in important nutrients (i.e., protein, energy or minerals), as nutrient requirements change throughout pregnancy.
- Provide proper supplementation during times of deficiency (e.g., protein or mineral supplementation during the winter months).
- Keep in mind that mineral supplementation is important for grazing herds, as forages rarely meet the mineral requirements of the cow.
- Properly manage calving areas.
- Ensure that calving areas are clean and dry, with plenty of dry bedding available.
- Don’t overcrowd crowding pens. Overcrowding can lead to calf injury and creates a heavier pathogen load due to the increased amount of manure in the pen.
- Remove animals from the calving area according to calf age. This prevents older calves from spreading pathogens to younger calves, who have a less robust immune response.
- Stay up to date on all dam and calf vaccinations.
- Work with your veterinarian to establish a cow and calf vaccination schedule.
