|January 1, 1982
Summary
Freshwater microalgae biomass supplementation in calves showed increased weight gain, particularly in hypotrophic animals. This study highlights microalgae as a potential feed additive for improving calf growth dynamics.
Area of Science:
- Animal Science
- Biotechnology
- Aquaculture
Context:
- Livestock production relies on efficient weight gain in young animals.
- Nutritional strategies are continuously explored to enhance animal growth and health.
- Microalgae biomass presents a sustainable and nutrient-rich feed alternative.
Purpose:
- To investigate the impact of freshwater microalgae biomass on calf weight gain dynamics.
- To assess the efficacy of microalgae supplementation in improving growth rates in young cattle.
- To determine the statistical significance of microalgae's effect on daily and total weight gain.
Summary:
- Ten 10-day-old calves received three subcutaneous injections of a 10% microalgae biomass suspension at 15-day intervals.
- Test calves exhibited higher weight gain on multiple observation days (10th, 25th, 40th, 60th, 90th) compared to controls.
- A statistically significant increase in weight gain was observed in twice-treated hypotrophic calves, with a 3.9g higher total gain over 30 days.
Impact:
- Microalgae biomass supplementation can positively influence calf growth performance.
- This research suggests microalgae as a viable feed additive for enhancing livestock productivity.
- Further studies could explore optimal microalgae strains and dosages for different cattle breeds and ages.
