Problems solved by technology

[0005] At present, in production practice, the weight of sows is measured by weighing, which is highly accurate, but for large-scale pig farms, weighing each sow individually will greatly increase the workload of employees During the process, it is easy to cause stress response to the sow, which greatly increases the labor intensity
The sow weight me

Embodiment Construction

[0038] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0039] refer to figure 1 , figure 1 A flow chart showing a method for gilt weight estimation; as figure 1 As shown, the method S includes steps S1 to S2.

[0040] In step S1, the morphological index data of the gilt is obtained, and the morphological index data includes chest circumference, age in days, backfat thickness at point P2, body length, hip height and leg width;

[0041] Among them, the bust is the circumferenc...

Abstract

The invention discloses a replacement gilt weight estimation method. The method comprises the steps of acquiring morphological index data of a replacement gilt, wherein the morphological index data comprise a chest circumference, a day age, a P2 point backfat thickness, a body length, a hip height and a leg width, a step of calculating the weight of the replacement gilt by using a constructed regression equation for estimating the weight of the replacement gilt, wherein the regression equation is as follows the body weight = -140.659 + 1.298 * chest circumference - 0.019 * day age - 0.034 * P2point backfat thickness + 0.408 * body length + 0.285 * hip height + 1.220 * leg width, R2 of the regression equation is equal to 0.929, and P is smaller than 0.001. According to the scheme, the bodyweight of the replacement gilt can be accurately estimated through the mutual combination of the morphological index data and the regression equation.

Description

technical field [0001] The invention relates to a technology for monitoring animal growth, in particular to a method for estimating the body weight of a gilt. Background technique [0002] Based on the significant benefits of intensive farming and the expansion of the market demand for livestock products, my country's breeding industry is developing rapidly in the direction of intensive management. At present, the scale level in my country has reached more than 60%, and the proportion of domestic scale breeding of more than 500 pigs per year has accounted for 45%. However, the current level of pig production in my country is still relatively backward, and it is very common for gilts to not come into heat or to come into heat late. Provide precise nutritional supply to gilts, resulting in overfat or underweight gilts, reducing the estrus rate of gilts. [0003] In large-scale pig farms, it is difficult to monitor the weight of gilts in real time. First, due to the large numb...
