Learn about the pros and cons of artificial insemination (AI) in dairy cattle, from safety and genetic selection to heat detection and cost considerations.

Learn how block calving systems streamline dairy farm management, lower production costs, and improve efficiency, along with key challenges to consider.

Learn about the three trimesters of bovine foetal growth and gestation, and see how maternal nutrition directly impacts calf development and birth health.

Compare reliable pregnancy diagnosis methods for cattle—including rectal palpation, ultrasound, progesterone testing, and PAG tests to improve herd fertility.

Understand the 21-day bovine oestrous cycle, primary behavioural signs of standing heat, and how progesterone testing accurately identifies fertile windows.

Learn about the critical role of progesterone in cow oestrous cycles, pregnancy maintenance, and how rapid milk tests improve heat detection on the farm.

Explore the causes, risk factors, and diagnosis of Cystic Ovarian Disease (COD) in dairy cows, and learn how it impacts herd fertility and profitability.

Learn about how genetic selection and indexes like EnviroCow help breed lower-emission dairy cattle with better feed efficiency and higher milk yields.

Explore essential dairy herd fertility metrics—including calving-conception intervals, submission rates, and conception rates to benchmark performance and boost farm profitability.

Understand the challenges of visual heat detection and learn how chemical and lateral-flow confirmation methods can improve submission rates and herd fertility.

Learn how timed artificial intelligence (TAI) and estrous synchronization protocols optimise dairy herd fertility, reduce fixed-time breeding errors, and improve farm profitability.

Trace the evolution of milk progesterone testing from early radio-immunoassays to modern rapid on-farm tests, and discover its impact on dairy cattle fertility management.
