Non-human animals and offspring thereof comprising at least one modified chromosomal sequence in a gene encoding a CD163 protein are provided. Animal cells that contain such modified chromosomal sequences are also provided. The animals and cells have increased resistance to pathogens, including porcine reproductive and respiratory syndrome virus (PRRSV). The animals and offspring have chromosomal modifications of a CD163 gene. The invention further relates to methods of breeding to create pathogen-resistant animals and populations of animals made using such methods.

A method for determining a matchmaking quality for a first mammal in relation to a plurality of different second mammals by comparing genotypes thereof, comprises steps of providing a first database and second database. The first database comprises genotyping data of known traits and coefficients weighting severity of said traits, and the second comprises genotyping data for at least certain loci common to each of said mammals to be matchmade. In determination of value of the match first results of the coefficients weighting the severities of the traits are determined for each potential breeding pair of the first mammal with each of said plurality of the different second mammals, and second results relating to a diversity are determined for each potential breeding pair of the first mammal with each of said plurality of the different second mammals. A total result determining the matchmaking quality for each potential breeding pair is determined by combining said first and second results for each of said potential breeding pair.

A mouse model may be used in evaluation of the change in intelligence level. The mouse model may be a mouse model with high intelligence level. The mouse chromosome of the mouse model with high intelligence level at least includes all or a portion of chromosome 1 originated from wild-type mouse. The evaluation includes performing a test which may be an open field test, sucrose preference test, water maze test, space exploration Y maze test, active avoidance Y maze test, and/or fatigue rotarod test.

An animal containment system includes a frame and a set of animal beds (e.g., plastic bins or similar) that are held in the frame for growing, mating, demonstration, sales, etc. When the animals are no longer present, the frame collapses, either horizontally or vertically, to reduce the amount of space consumed by the frame, as it is often possible to stack the animal beds, one inside each other, thereby reducing storage and transportation space requirements.

Embodiments of the present disclosure provide systems, apparatuses and methods for regulation hormone production in mammals. Examples include but are not limited to by creating electro-magnetic wave emission pulse trains (photons) of individual color spectrums in sufficient intensity to drive hormone production in a mammal, using a characteristic frequency or pattern to minimize the required input power necessary to regulate hormone production, while also allowing for the monitoring of the power consumption and other variables of the system. By controlling the duty cycle, intensity, wavelength band and frequency of photon signals to a mammal, production of specific hormones can be regulated through the cycling between blue, green, yellow, near-red, far-red, infrared and ultra violet photon modulation.
