Release of the mature egg occurs 24-30 hours from the commencement of the standing heat. The site on the ovary where the egg was released collapses, and the structure re-forms to become a corpus luteum (CL). Optimum fertility of the egg is 6 to 8 hours after ovulation (Average 6 hours for conventional frozen semen,

A clear understanding of the anatomy and physiology of reproduction in cattle is the necessary foundation for a successful artificial insemination program. Before attempting to inseminate cattle, you must have a clear picture of the anatomy of the female reproductive tract. This includes an understanding of the many signs of oestrus and when cattle should

The oestrus cycle is the hormonal regulated reproductive cycle of cattle, generally defined as a period from one ovulation to the next. In normal, empty cattle the regular oestrous cycle repeats every 18 to 24 days in response to changing levels of different hormones. Stages of the oestrus cycle Select each of the + signs
