Beginners are interested in how you candetermine the weight of pigs: the animal's live weight and slaughter weight. And how can this be calculated if the farm does not have special weights and devices that allow it to be done?
Methods to calculate the weight of pigs
Live weight of an animal is easily calculated by formulas. The most running is.
Длину туловища перемножают с обхватом груди animal and the result is divided by a constant. For greasy pigs, this will be the number 142. To calculate the live weight of the pig of the meat-and-fat breed, it is necessary to take the constant 156. If the animal is thin, then divide it by 162.
There is another formula that allows you to calculate the weight of pigs. Live weight of the animal is also calculated after taking measurements - chest girth and trunk length.
1.54 should be multiplied by the chest girth and folded with a product of 0.99 and the length of the trunk.
Sometimes farmers use a specially designedtable for determining the weight of pigs. Live weight is found all the same parameters - the girth of the chest and the length of the trunk. Having found the corresponding vertical and the necessary parallel, at the intersection they look at the figure. It just indicates the animal's live weight in kilograms.
Difference of the real indicator from the calculated
Live weight is the real weight of an animal in normal life. It usually changes during the day. Therefore, it is considered correct to talk about the live weight of a pig two to three hours before feeding.
Distinguish the net weight of the animal, that is, the massbody without contents of the bladder, intestines and stomach. Most likely, the formula to determine the difference between net weight and live will be quite difficult. Based on practice, experienced breeders still do not recommend trusting the formulas and the table for determining live weight one hundred percent. After all, the result may differ from the real by 20-30 kilograms.
Therefore, it is best to determine more precisely how much a pig weighs, using the traditional method, before buying or selling. That is, there is nothing more accurate than the good old scales.

Carcass weight without head, lower legs, tail andviscera called slaughter weight. It can be calculated in advance, that is, before the slaughter of the animal. Enough to know the live weight of the pig. Of course, the result will not be absolutely accurate, but presumptive.
Typically, the meat yield on the bone - slaughter weight - ranges from 60 to 85% of live weight. And the less fatness pig, the lower the percentage.
