In conclusion, there is no significant relationship between estrogen concentration and cervical mucus viscosity levels in Aceh cattle. An examination of cervical mucus showed different consistencies: five cows had mucus with a thick viscosity, with a 20% pregnancy rate two had mucus with a moderate viscosity, with a 50% pregnancy rate and one had mucus with a thin viscosity, with a 100% pregnancy percentage. Meanwhile, the groups with a cervical mucus pH 7 and 8 had a pregnancy rate of 50%. The pregnancy rate in cows with a cervical mucus pH of 6 and 9 was 0%. The estrogen concentrations of each type of cervical mucus, namely thick, moderate, and thin were 29.39☖.29 23.24±4.62 and 30.93 pg/mL, respectively. Blood and cervical mucus samples were collected during the first cervical mucus secretion.

Afterward, observation of estrus signs was performed for 30 minutes at 06:00 a.m. Eight females Aceh cows aged 3-7 years old, with body weights of 150-250 kg were synchronized using a 25 mg single dose injection of PGF2 α. He was elected a Fellow of the American Academy of Arts and Sciences in 2014.Abstract | This study aimed to investigate the relationship between cervical mucus viscosity and estrogen concentration, several blood biochemical profiles, and blood macro-mineral levels, as well as to determine the effect of cervical mucus viscosity and pH differences on pregnancy rates in Aceh cattle.

His most recent book, The Shark Handbook, is a must buy for all shark enthusiasts. He has written dozens of scientific research papers and has appeared in a number of film and television documentaries, including programs for National Geographic, Discovery Channel, BBC, and numerous television networks. Greg has been an avid SCUBA diver and underwater photographer since 1978. Much of his current research centers on the use of acoustic telemetry and satellite-based tagging technology to study the ecology and behavior of sharks. His shark research has spanned the globe from the frigid waters of the Arctic Circle to coral reefs in the tropical Central Pacific. For more than 30 years, Greg has been actively involved in the study of life history, ecology, and physiology of sharks. He holds a master’s degree from the University of Rhode Island and a Ph.D. He is also adjunct faculty at the University of Massachusetts School for Marine Science and Technology and an adjunct scientist at the Woods Hole Oceanographic Institution (WHOI). He has been a fisheries scientist with the Massachusetts Division of Marine Fisheries since 1987 and currently heads up the Massachusetts Shark Research Program.
