China is the first in the world big country of raising pigs.In the industry of raising pigs, seed selection, the breeding of boar are extremely important.Whether outstanding quality and the quantity that determines the commodity pork pigs of pig farm seed selection boar out.The boar of high-quality can more, the better pork pigs of bred.Therefore, it is just extremely important how to select high-quality boar.
The boar seed selection need to be measured the pig with good Genetic lineages of 75 kilograms～115 kg body weight, will regularly survey the data such as body weight gain amount, back-fat thickness, eye muscle area of vivo porcine between test period.When measuring, need to use " boar determinator " to carry out.But, " boar determinator " of the prior art, ubiquity following problem:
1, the weighing body weight of live body pig is inaccurate;
2, reading numerical values is inconvenient;
3, the back-fat thickness of live body pig is measured inaccurate;
4, the eye muscle area of live body pig is measured inaccurate.
Defects is mainly touched by the live body pig and is caused.
For above several problems, some following solutions have also appearred in the prior art:
For the inaccurate problem of weighing, the form of available technology adopting half machinery, half-electron scale formula.Install 2 grades the mechanical edge of a knife (edge of a knife of former steelyard) additional at scale body and outside framework junction, and add flexible spring steel plate.Its objective is for buffering or after offsetting the upper scale of pig because of the movable power that has nothing to do with itself body weight that produces.This kind mode can be eliminated the external force of small part because the resetting property of stretching of the frictional resistance of the edge of a knife, edge of a knife hysteresis quality, spring steel plate.But also because the hysteresis of scale body mechanical part, frictional resistance, with being rigidly connected of outside framework, caused the impact that the pig ABW is measured.And this impact is very large.Error is mostly more than 2 kilograms.
For the problem of reading difficulty, the observing apparatus numerical value that available technology adopting is artificial need be waited until when instrument numerical value is relatively stable, grabs and reads show value.Obviously also there is error in this mode.
For surveying the inaccurate problem of back-fat thickness, use B-ultrasonic instrument for veterinary use to measure back-fat thickness, whether movable but whether the data that the B ultrasonic instrument records accurately depend on pig fully.Existing technology is more reasonable with scale body width design just, and scale body inside casing width design is 380mm.Generally speaking, the pig across back of 100 kilograms of body weight is 380mm; After the pig that body weight is 75 kilograms entered the scale body, the space, both sides was larger, and pig is very easy to touch, and caused the B ultrasonic indeterminacy; It is harder that the pig that body weight is 115 kilograms enters scale body frame, because width is little, causes and catch up with the upper scale of pig very difficult, wastes time and energy, and efficient is low.
