Summary
The combined use of sodium selenite, vitamin E, and dexamethasone is most effective for inducing calving in cows, improving calving duration and reducing complications. Lowering calf birth weight in heifers also prevents difficult births and shortens the postpartum period.
Area of Science:
- Veterinary Medicine
- Animal Reproduction
Context:
- Inducing parturition in cattle is a common practice to manage calving.
- Various hormonal and nutritional interventions are used, but optimal protocols require further investigation.
Purpose:
- To evaluate the efficacy of different preparations for inducing calving in cows and heifers.
- To assess the impact of specific treatments on calving outcomes and postpartum recovery.
- To determine the influence of calf birth weight on dystocia and postpartum duration.
Summary:
- Combined administration of sodium selenite, vitamin E, and dexamethasone resulted in improved calving duration, reduced postpartum complications, and shorter service periods in cows.
- Injecting heifers with 30 mg of fortecortin and managing calf birth weight (average decrease of 6 kg) helped prevent dystocia and shorten the postpartum period.
- Monitoring progesterone and estradiol levels in cows undergoing induced parturition provided insights into the physiological changes associated with these interventions.
Impact:
- The findings provide evidence-based recommendations for optimizing induced calving protocols in cattle.
- Improved calving management can lead to better animal welfare, reduced economic losses, and enhanced reproductive efficiency in dairy and beef herds.
- Understanding the hormonal dynamics during induced parturition can aid in developing more refined reproductive strategies.
