Cystic Ovarian Disease

Infertility in Cows: Cystic Ovarian Disease What is Cystic Ovarian Disease in cattle? Cystic ovarian disease (COD) is a major problem associated with poor fertility in dairy cattle. Reportedly, from 6 to 19% of dairy cows develop cysts. It is possible, however, that the incidence of the disease is as high as 60%, as many heifers recover without intervention1, meaning they may go undetected. It is characterised by the presence of at least one enlarged anovulatory follicle on one or…

Heat Detection: Is Your Heat Detection Method Ineffective?

Heat Detection: Is Your Heat Detection Method Ineffective? Why do we need heat detection? Heat detection is an essential component of the dairy industry. Missed or mistimed heats lead to increased calving periods and a resulting financial burden. Similarly, wasted Artificial Insemination (AI) and loss of pregnancies caused by mistiming of AI adds to this financial burden.  There is a plethora of heat detection aids on the market, ranging from simple mount detectors to fully automated robotic in-line systems. These…

Progesterone in Dogs: Assessment of Heat and Whelping

Progesterone in Dogs: Assessment of Heat and Whelping For dog breeders, one of the most difficult parts of breeding can be identifying the right time to mate. Female dogs usually have just two seasons a year, and the fertile window can be very small. Even though a bitch might show bleeding and behavioural signs of heat for over 2 weeks, her fertile window might be as narrow as just a few days. progesterone testing is one of the ways breeders…

Milk: an incredible life perpetuating commodity which can also be used as a health monitoring tool.

Milk: an incredible life perpetuating commodity which can also be used as a health monitoring tool. What is milk? Milk originates as the special fluid produced by mammals to feed their young – young that range from Wildebeest young where the precocious new born calf is ready to run with the herd within hours of birth to mammals where the young has to be supported by its mother or parents for years (as is the case with humans!). What are…

Milk and its many uses

Milk and its many uses An introduction to milk Years ago, a cow’s milk was produced for the sole purpose to be suckled by her calf.

International Women’s Day: Female African Dairy Farmers

International Women’s Day: Female African Dairy Farmers The numbers on a poster on the Health For Animal website marking International Women’s Day on the 8th March, caught my attention: two thirds of the 600 million poorest livestock keepers globally are women. 90% of the income they earn is ploughed back into their family or society. In East Africa, dairy is the biggest industry for female livestock keepers. This is a population of small holder farmers that produce milk for their family and…

Progesterone profiles in dairy cows: what can they tell us?

Progesterone profiles in dairy cows: what can they tell us? The previous article in this series from Ridgeway Science reviewed the dairy cow oestrus cycle and we’re following that with a more detailed look at the progesterone-dominated luteal phase of the cycle, reported by Blavy and colleagues in 2016. What is Progesterone? Progesterone is a steroid hormone and is produced by the corpus luteum in the ovary after ovulation. If a cow becomes pregnant, the corpus luteum will be maintained…
