Abstract: A solar inner red dot sight includes a body, a power supply and a solar cell arranged on the body, a control circuit board and an LED light-emitting chip arranged on or in the body, a photoelectric sensor arranged on a side of the LED light-emitting chip, wherein the photoelectric sensor is used to collect illuminance signals of a shooting target or surroundings thereof; the control circuit board obtains power supplied to the LED light-emitting chip according to the signals of the solar cell and the illuminance signals of the photoelectric sensor, and compares the power with the solar energy, when the solar energy is less than the power energy, the control circuit board turns on the power supply to power the LED light-emitting chip; or when the solar signal is strong, the LED light emitting chip is powered by the solar cell only.

Abstract: An LED mounting base, an adjustment mechanism with the LED mounting base and a red dot sighting device with the adjustment mechanism are provided in the present disclosure. The LED mounting base includes a sliding block base and a pedestal in which an LED chip is mounted at the middle of the front end surface thereof. A sliding slot parallel to the length direction of the pedestal is disposed on the front end surface of the sliding block base. One end of the sliding slot is a blind end, and the other end of the sliding slot is an open end. After the pedestal being disposed in the sliding slot, the front end surface of the pedestal is parallel to the front end surface of the sliding block base. The LED mounting base which is modular in design and more compact, is less affected by the gap. The resultant force generated when adjusted in the two-dimensional directions of up and down as well as the left and right is decomposed into a single direction.

Abstract: Methods are provided for screening pigs to determine those more likely to produce larger litters. The screening method detects the presence of particular alleles in the genome, and in a preferred embodiment, the screening is performed by nucleic acid analysis. Specific primers as well as kits for carrying out the methods of the invention are also provided.
