An electrical system having an underlying structure having a helical shape is used to produce useful electromagnetic effects for agricultural applications, including promoting growth of animals.

An attachment apparatus for use in combination with a known low-level laser therapy device. The apparatus is attachable to the front portion of, and operable with, a low-level laser therapy device for passing coherent light past the fur of an animal patient. The apparatus has a body with a plurality of pins that can be pushed through the fur, and which transmit a low-level laser therapy light to skin of the animal. The pins are composed of material that transmits the required light wavelength to the animal's skin.

The disclosed sleeve according to various aspects of the present technology may comprise a tubular body adapted to be fitted around a barrel of an injection gun. The tubular body may comprise an interior surface and an exterior surface. The interior surface may define a cavity in the tubular body for receiving the barrel of the injection gun, wherein the interior surface may be configured to enclose the barrel of the injection gun. The exterior surface may comprise at least one marking formed thereon. The sleeve may also comprise an open first end terminating in a first peripheral annular edge and an open second end opposite the open first end and terminating in a second peripheral annular edge.

System for detecting the level of discomfort of aquatic animals during experimental studies, with a water tank, a reference electrode placed at one of the sides of the tank, at least one recording electrode placed at another side of the tank, a bio amplifier for amplifying a received bio-signal at the recording electrode, a microprocessor for treating the signals and a low-pass filter for filtering the signals received. The system can provide a precise, quantifiable and specific indication of the level of stress/wellbeing of aquatic animals in normal living conditions as well as in experimental conditions without interfering with the animals' life.

Methods and systems for detecting the presence of irregularities in milk, and for assessing a health state of a lactating mammal, are provided. A sample of milk is illuminated with a light beam. Scattering data resulting from an interaction between the light beam and the sample of milk is collected. The scattering data is processed to detect the presence or absence of light scattered at a predetermined angle relative to a normal orientation, for instance to determine at least one characteristic of the sample of milk. Based on the presence or absence of light, the presence of irregularities in the sample of milk can be determined, for instance to assess the health state of the lactating mammal based on the at least one characteristic of the sample of milk.

A system is provided for collecting cellular material from fish for subsequent DNA analysis. A channel includes a sample collection zone. A fluid ejector is directed into the sample collection zone. A fluid collector is communicated with the sample collection zone. A controller is configured to coordinate ejection of a fluid jet from the fluid ejector and collection of a fluid sample by the fluid collector. The fluid jet dislodges cellular material such as scales and mucous from the fish. The fluid collector collects that cellular material in a fluid sample for subsequent DNA analysis.
