Method and system for recognizing individuals with abnormal weights in poultry group

Abstract

The invention provides a system and method for monitoring weights of individuals in a poultry group. The method comprises the following steps: measuring the weight of a single poultry or the weights of lots of poultries repeatedly until the weight of every poultry in the poultry group is measured once at least, recording weight data measured every time, and recognizing poultry individuals of whichthe weights are measured every time to obtain identity data of all the poultries measured every time; forming a nonhomogeneous system of linear equations according to weight data obtained by measurement every time and the corresponding identity data of the poultries measured every time, and calculating to obtain the weight of every poultry individual in the poultry group; and calculating the average weight of the poultries in the poultry group and a normal weight range of the poultry individuals according to the individual weight of every poultry in the poultry group, and recognizing the poultry individuals of which the weights are not in the normal weight range. By the method, the poultries with abnormal weights can be assisted to be classified from the poultry group, and normal growth conditions of the whole poultry group are ensured.

Description

technical field [0001] The invention relates to the field of poultry data management, and more specifically, to a method and system for identifying individuals with abnormal body weight in poultry flocks. Background technique [0002] Live body weight is an important indicator to characterize the breeding status of chicken flocks (broilers and layers) at a specific time point. The early live body weight of the chicken flock is the basis for the future growth and development of the chicken flock, and the live body weight of the laying hen when it enters the laying period has a crucial impact on its future laying efficiency. [0003] The uniformity of the flock in terms of body weight, known as flock uniformity, has a significant impact on the flock's productive potential. Studies have shown that the uniformity of the 16-week-old flock is positively correlated with its egg production persistence and survival rate. Breeding chicken flocks with high uniformity can further deve...

Problems solved by technology

[0006] In order to solve the problem in the prior art that the weight monitoring process of poultry requires manual extraction and weighing of poultry individuals, the number of poultry that can be weighed at the same time is small, and at the same time it may cause disturbance to the growth of poultry, a poultry weight is provided.
