Sexed pig semen may be a step nearer to commercial application after a successful European experiment. The trial used a new artificial insemination catheter to inseminate three sows, one with female sexed semen and two with unsexed semen. One of the sows inseminated with unsexed semen produced six male and two female piglets at 113 days after insemination. While previous sexed semen trials have yielded successful results, they relied on surgical insemination methods. Semen for the trial was sexed by flow cytometry. Using a new insemination catheter, semen was delivered to the uterine horn, reducing the number of sperm required.

    microRNAs (miRNAs) are a class of negative regulators that take part in many processes such as growth and development, stress responses, and metabolism in plants. Recently, miRNAs were shown to function in plant nutrient metabolism. Moreover, several miRNAs were identified in the response to...
