Abstract

The invention provides an egg to be hatched weight determining method. The egg to be hatched weight determining method mainly comprises monitoring the weight loss during a process of hatching hatching eggs into chicks to obtain a chick-egg ratio, monitoring the weight loss during a chick storage process to obtain a first weight loss rate, monitoring the weight loss during a chick transportation process to obtain a second weight loss rate, and according to the chick-egg ratio, the first weight loss rate and the second weight loss rate to determine the relationship between the weight of chicks required by customers and that of the hatching eggs; according to the weight of chicks required by the customers, determining the required weight of eggs to be hatched. By studying the weight losses during hatching egg hatching, chick storage and chick transportation, the egg to be hatched weight determining method controls and determines the weight of the eggs to be hatched, reduces hatching of low-weight hatching eggs, improves the proportion of qualified chicks and accordingly increases the annual economic benefits of the eggs to be hatched. The egg to b hatched weight determining method improves the quality of the chicks, enables the customers to receive the chicks meeting the requirements on weight, and further enhances the customer satisfaction.

Description

technical field

[0001] The invention relates to the technical field of breeding feed, in particular to a method for determining the weight of hatched eggs. Background technique

[0002] Customers are the foundation of an enterprise's survival, and product quality is a prerequisite for ensuring customer satisfaction. As customers have higher requirements for Yukou chicks, in order to meet customer requirements, the hatchery is committed to research on how to improve the quality of chicks.

[0003] Among the customer's requirements for chick quality, the most basic requirement is to require the chick to have a weight of more than 33g from the factory, and the weight of the chick to be delivered to the farmer should not be less than 30g. , may cause some chicks to be thin and small when they reach the customer, and customer satisfaction is low. Therefore, how to control the body weight of chicks has become an important task for hatcheries. Contents of the invention [0004...

Examples

Embodiment

[0038] 1S: Monitoring the weight loss of the egg hatching process:

[0039] Eggs of different varieties and ages were hatched, and 9 batches of embryonated eggs were randomly sampled to monitor the weightlessness of embryonic development. 168 breeding eggs were sampled for each batch of breeding eggs, and the weight of the hatching eggs was weighed when the eggs were hatched. They were hatched at the first predetermined temperature of 37.6-38.2°C and the first predetermined humidity of 49-70%. After the eggs hatched into chicks, weighed Weight, calculate chick egg ratio A. The calculation formula is: chick-to-egg ratio = chick hatching weight / incubating egg weight.

[0040] See Table 1 below for the monitoring results of egg hatching weight loss rate and chick egg ratio:

[0041] Table 1

[0042]

[0043]

[0044] Result analysis: After hatching for 21 days, the weight of the chicks accounts for 65.9-70.4% of the weight of the hatched eggs. There is little difference ...
