Low (re)productive efficiency on cow-calf farms are associated with lower financial returns and affect significantly the economic result of the productive sector constituting a limitation to expected growth. Therefore, it is necessary to identify what is causing low (re) productive efficiency in order to allow application of corrective techniques. A relevant factor able to improve (re)productive efficiency is having adequate calving intervals which have a positive impact on financial returns and a positive impact on costs. Looking for one delivery every 365 days, with fertile beneficiation right after leaving the bull to the herd; and the minimum time to eat without being re-productively functional (385 days, 100 days, 0 * 0.75 respectively). This is essential in a global market: to have animals and techniques that lead to efficiency. The difference between an annual fertility of 85% and 90%, could simply mean the abandonment of activity. Improve (re)productive efficiency is identified as a good practice to improve financial and economic results.
The perception that having a difference between an annual fertility of 85% and 90%, could simply mean the abandonment of activity. Through a careful reproduction management plan it is possible to have a cow-calf herd having a delivery within one year. Looking for one delivery every 365 days, can be done with fertile beneficiation right after leaving the bull to the herd; and the minimum time to eat without being re-productively functional. A cow with a lower calving interval will be more efficient since it will deliver a higher number of calfs in its productive life. Therefore for the same cost of maintaining the cow, the return will be higher. On a cow-calf herd having a delivery within one year, and the calf with the appropriate weight for the market, are part of the key factors identified for business success.
Main challenges and bottlenecks in the implementation process can be identified. A high awareness of the need for cow-calf farmers to take records of all cows, concerning delivery dates and other information, so that the calving interval of each cow can be properly monitored and registered. This awareness can be triggered by beef cattle farmers’ organizations, consultants and public animal health services. Main bottlenecks are the capability of having updated, correct and reliable records. Key success factors in the implementation process are keep up-to-date, as well as accurate and reliable records.
This innovation can impact on other thematic areas. Adequate calving interval according to each farm reality identified as a key factor for a successful business can have a positive impact on animal health and welfare. By improving fertility and replacement rates it can also have an impact on production efficiency.
