Validation of a luciferase bioassay to detect the progestative activity in gilts whose estrus was induced by an uterotonic herb ; Ligusticum chuanxiong

, 2014
[[abstract]]Ligusticum chuanxiong (LC) is an uterotonic herb. Ethanol extract of LC has potent progestative activity. The progestative activity in rat serum was well documented after oral and subcutaneous administration of LC. The objective of this study

Synchronization of Estrus in Dairy Heifers: A Field Demonstration

Journal of Dairy Science, 1986
Use of prostaglandin F2 alpha to synchronize estrus was demonstrated over 3 yr with 2966 dairy heifers in 45 herds. Reproductive status of all heifers was determined before any injections occurred. Anovulatory heifers (8.3%) were not injected or inseminated. Ovulatory heifers received one intramuscular injection and most heifers received two injections

Synchronization of estrus and insemination time in beef cows

, 1977
What's Ahead for Cattlemen? is known as Cattlemen’s Day, 1977We used 76 cows to determine the effect of inseminating at different times after detecting estrus and to evaluate Synchronization B as an estrus synchronizing agent. Cows were divided into five
