Recently visited several pig farms and found that pig ears are not the same number, ask the breeder some I do not know how much? What does each gap mean? Although each field can be defined according to its own situation, there are two methods that are currently used.
The purpose of the ear number is to number individual piglets and record their origin, kinship, growth rate, and production performance. The ear number should be heard within 1-3 days after the piglet is born. The ear number is used to use ear clamps to make a gap in different parts of the ear. Each gap represents a piece of data. Adding all the data is the ear number of the pig. At present, there are two kinds of pig's ear number, one is the big number, the other is the nest number method. However, there must be a unified use of an ear number method to prevent the confusion of the ear number. The general lack of a tip of the ear is 3, the ear is missing a 1, not playing 0, the front of the right ear is a thousand, the trailing edge is a bit, the front edge of the left ear is a hundred, and the trailing edge is a ten.
(1) Large numbering method: To remember the numbers represented by the left and right ears and the gaps on the upper and lower sides, the sum of the number of gaps on both ears is the number of the pig.
(2) WoW method: The left ear is the symbol for the nest number, and the right ear is the individual number for the pig. Record the number of gaps on the ear, the sum of the number of gaps in the left ear is the socket number, and the sum of the number of gaps in the right ear is the individual number of the pig.
Precautions
(1) Prevention of inflammation of notch infection results in deformation of gap adhesion.
(2) The pigs are forbidden to be fostered, especially among colorless breeds, before the earings are not completed.
(3) Each ear of a farm is unique.
(4) The distance should be larger than the spacing: The gap between the ear and the ear tip must be larger, at least larger than the gap between the ear root or the tip of the ear, so as to distinguish the gap between the ear root and the ear tip. It also requires that the depth of the gap is consistent, but it is deep and shallow, clear and easy to identify, and the spacing between the gaps is basically the same, sparsely uniform, and neatly arranged.
(5) The blood vessels should be avoided as much as possible. All ears should be cut to the ear marginal bones moderately, not too deep and not too shallow.
