The key drivers of profitability and reproductive efficiency in your dairy herd is in submission and conception rates.
Target for submission rate should be +90% meaning that 90% of the herd coming into heat and inseminated in the first three weeks from the beginning of the breeding season of the portion of the herd you want to breed.
Factors influencing the submission rates on all farms are:-
- Cow Reproductive Cycle
Averagely cycling should return to a dairy cow 15-20 days post-calving and the first cycle or heat should appear within 25 days and return every 18-24 days after that. Poor reproductive efficiency in farms has to do with problems of both accuracy and efficiency in detection of oestrus.
- Cow Health
Sound cow health improve efficient submission and conception rates. Good oestrus cycle is determined by positive energy balance and a healthy uterus. Having cows in good physical shape with regards to hooves, legs and muscle is also essential.
- Conception Rates
Conception rate is determined by effective timing of insemination. It’s important to achieve 90% submission rates on your farm, you need to consider twice-a-day insemination or at least altering the time of insemination.
Inseminating cows at the right time matters to your dairy’s bottom line, it’s important for farmers to catch cows in heat when it’s most productive to breed them. There tools farmers can use to track heats effectively so that they won’t spend time watching for heats or worry about missing a heat.
- Monitoring Breeding Season
Farmers need to monitor cows prior to the breeding season to maximize efficiency. Farmers must know that all cows that are not cycling by day 42 must be examined by an experienced veterinarian. A cow’s heat lasts for 6 – 8 hours, therefore there are easier technologies that help farmers manage millions of dairy cattle 24 hours a day monitoring every cow in the herd for: heat activity; resumption of cyclicity; and conception.
