Farmers using more technologies in cow-calf production systems achieve higher weaning rates. Adopting improved pasture, artificial insemination, and better nutrition can boost herd efficiency for all farmers.
Area of Science:
- Animal Science
- Agricultural Economics
Background:
- Cow-calf production systems are crucial for beef supply chains.
- Optimizing weaning rates is essential for economic viability in cattle farming.
- Technology adoption varies significantly among producers, impacting herd performance.
Purpose of the Study:
- To analyze the relationship between technology adoption and weaning rates in Brazilian cow-calf operations.
- To identify specific technologies associated with higher reproductive performance.
- To categorize farmers based on their technology adoption and weaning success.
Main Methods:
- Surveyed 73 farmers in Rio Grande do Sul, Brazil, regarding 48 reproductive performance technologies.
- Employed multivariate analysis with a non-hierarchical cluster method to group farmers.
- Set the significance level at P < 0.05.
Main Results:
- Three farmer clusters emerged: low (LWR, 59% weaning rate), intermediate (IWR, 72%), and high (HWR, 83%).
- IWR and HWR groups utilized improved pastures, fixed-time artificial insemination, birth weight selection, and proteinated salt more than LWR.
- HWR farmers used stocking rate control, while IWR farmers employed ultrasound more than LWR.
Conclusions:
- Higher technology adoption in cow-calf farms correlates with increased weaning rates.
- Nutritional and reproductive technologies are key drivers of improved herd performance.
- Disseminating successful technologies can enhance efficiency for less productive farmers.
