The owner of a farmstead who is bringing up pigs, without having scales, can, having familiarized with the table, to define approximate weight of an animal.
Autumn – summarizing time in animal husbandry. Someone grew up living creatures for requirements of the family, another zabivaet animals and itself takes out meat on sale. But is also tayoky which grew up one and even several pigs or some bull-calves and want to sell them. But, that the transaction took place, neobxodimo to know weight of animals. Earlier practically in any village was weight – big scales on which without problems it was possible to weigh animals. Now in most cases such scales became unfit for use, and people resort to "weighing", or rather determination of weight of animals on measurements.
At once it is necessary to disappoint readers: determination of weight of animals on measurements gives very approximate rezultaty. And, certainly, the trained buyers of animals reduce these netochyonost in own favor. As it it is difficultly to avoid, tell.
For example, there are pigs of grease type. At them short, but a thick body, At pigs of meat type a body extended (see fig.). Or, say, the bull-calf can be thin, but the length of his body will be same, as well as at well-fad. Differently, determination of weight of animals on a measurement gives information only about very approximate weight zhivotyony, and at their sale it is desirable this way not to use. But if there is no possibility to learn mass of an animal on scales, use given tabliyotsy and the scheme of measurements. As they say: Where ours didn’t vanish!
Length of a trunk measure by a roulette to within 1 cm from the middle of a zatyyolochny crest, between ears, on the veryokhny line of a neck, withers of a back, a poyasyonitsa and a sacrum to a tail root (that is to the last kresttsovy vertebra). Thus the head of an animal should naxoditsya in such situation that the line of the bottom jaw, necks and breasts was as though line continuation zhivota and formed with it a straight line.
Grasp of a breast measure on the vertikalyyony line concerning back knots of shovels. Thus watch, that the tape didn’t run into a body of animals, but also didn’t lie freely on a bristle.
Knowing length of a trunk and a grasp grudi, it is possible to define live mass of the zhivotyony by the given tabyolitsa. Let’s assume that length tulovishha – 102 cm, a breast grasp – 104 see. In a place of crossing of these figures we find number 86. It also is approximate live weight of an animal.
