Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides a method for estimating the weight of pigs, which has the advantages of estimating the weight of pigs through measurement, etc., and solves the problem that weighing measurement easily causes pigs to have a stress response, thus affecting their mental state , in the future, reduce the subsequent feeding rate, and at the same time forcefully drive the pigs on the scale, it is easy to cause the pigs to injure the operator, so there are certain safety hazards

Embodiment 1

[0029] A method for estimating the weight of pigs, the specific operation steps are as follows:

[0030] S1. First, select healthy and uniform pigs to weigh at different ages, so as to obtain the actual weight of the pigs;

[0031] Among them, the weighing time periods are six months, nine months, and the time of slaughter.

[0032] Among them, the pigs were kept on an empty stomach for 10 hours when weighing.

[0033] S2. Clean up the tested pigs, and clean up the sundries attached to their fur, so as to ensure the accuracy of subsequent data.

[0034] S3. Use a tape measure to measure the chest circumference cm and length cm of the pig under test. When measuring the pig, the pig hair can be removed from the measured position of the pig according to actual needs, thus improving the accuracy of the data;

[0035] Among them, the chest circumference is the vertical circumference of the chest measured with a tape measure at the rear edge of the pig's shoulder blade, and the ti...

Embodiment 2

[0043] A method for estimating the weight of pigs, the specific operation steps are as follows:

[0044] S1. First, select healthy and uniform pigs to weigh at different ages, so as to obtain the actual weight of the pigs;

[0045] Among them, the weighing time periods are six months, nine months, and the time of slaughter.

[0046] Among them, the pigs were kept on an empty stomach for 10 hours when weighing.

[0047] S2. Clean up the tested pigs, and clean up the sundries attached to their fur, so as to ensure the accuracy of subsequent data.

[0048] S3. Use a tape measure to measure the chest circumference cm and length cm of the pig under test. Use a tape measure to measure the chest circumference cm and length cm of the pig under test. When measuring the pig, the measured position of the pig can be eliminated according to actual needs Pig hair, thus improving the accuracy of data;

[0049] Among them, the chest circumference is the vertical circumference of the chest ...

Abstract

The invention relates to the technical field of livestock breeding, and discloses a pig weight estimation method, which comprises the following specific operation steps: S1, firstly, selecting healthy pigs with uniform body types, and weighing the pigs at different day ages, so as to obtain the actual weights of the pigs; and S2, cleaning the tested pig, and cleaning sundries adhered to the fur of the tested pig, so that the subsequent data accuracy is ensured. According to the pig weight estimation method, the weight of the pig is estimated by using the method, so that when the pig is sold on a small scale, the pig does not need to be specially pulled to a weighing position for overall weighing, the stress reaction generated in the weighing process of the pig is reduced, unnecessary troublesome operation of a feeder is reduced, and the labor intensity of the feeder is reduced. The pig weighing device is simple in structure and convenient and fast to use, enables pigs to be weighed more conveniently and quickly, reduces labor intensity increase caused by manual weighing, reduces financial expenditure generated by purchasing weighing equipment, and ensures the life form stability of the pigs at the same time.

Description

technical field [0001] The invention relates to the technical field of livestock feeding, in particular to a method for estimating the weight of pigs. Background technique [0002] Pork is one of the most important animal foods on the table and the most important source of animal protein for the general public. With the improvement of living standards, people's demand for pork has changed from quantity to quality, and the demand for lean meat has increased significantly. The breeding programs of breeding pigs in various countries in the world are also turning to improve the meat production performance of commercial pigs; [0003] In the field of pig breeding, in order to better grasp the growth of pigs, such as changes in body weight, it is necessary to regularly monitor the weight of pigs. [0004] In the prior art, the weight estimation of pigs is mainly carried out by means of manual measurement such as electronic scales. This method requires a lot of labor, and at the s...
