The invention relates to a compact, comfortably wearable system (1) comprising a plaster (2) and a radiation device (3) in a stacked position on top of the plaster. The radiation device (3) comprises a light-guide (9) which is optically connected and edge-lit by a radiation source (10). The radiation source (10) is electrically connected to an energy source (11), which is stacked on top of the light-guide 9. A reflector (12) is provided to reflect radiation in the direction of a target area (6). Due to total internal reflection (TIR) inside the light-guide (9) and multiple reflections a spreading is obtained of each of the radiation rays (15) generated by the radiation source (10), which results in the target area to be evenly irradiated.

The invention relates to a livestock synchronous ovulation and fixed-time artificial insemination method. The method includes: intramuscularly injecting GnRH (gonadotropin releasing hormone) or analogues thereof to cows in any day of an estrus period, injecting PG (prostaglandin) or analogues thereof after 7-8 days, and injecting the GnRH or the analogues thereof for the second time after 2-3 days. Twice fixed-time artificial insemination in advance or twice fixed-time artificial insemination in delay is carried out respectively according to follicular development conditions of the cows. By regulation of follicular development time of the cows, fixed-time artificial insemination is carried out in relatively fixed estrus time to increase sperm-egg binding probability and the estrus conception rate of the cows, and accordingly reproduction efficiency of the cows is improved. In addition, compared with a conventional OFAI (ovsynch and fixed-time artificial insemination) technology, the livestock synchronous ovulation and fixed-time artificial insemination method has the advantage that the estrus conception rate is increased by 10%-15% due to avoiding of estrus diagnosis before insemination, thereby having promising market application prospect.
