Problems solved by technology

The traditional Peking duck sebum rate selection technology is based on the fat weight of the whole siblings to estimate the sebum rate of the remaining individual. This method requires the slaughter of a large number of live Peking ducks, which is time-consuming and laborious. In addition, some excellent individuals will be eliminated, resulting in Certain economic losses and genetic estimation deviations lead to problems such as poor accuracy of selection work and slow genetic progress

Embodiment Construction

[0031] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0032] Such as figure 1 Shown, the invention provides a kind of duck skin fat rate seed selection method, comprises steps as follows:

[0033] 1) A predetermined number of 1-day-old ducklings are raised in the first stage under the predetermined feeding conditions and feeding time; during the first stage of feeding, each duckling is equipped with a kind of bird wing number for recording; During the stage feeding period, the dead ducks and sick ducks should be eliminated.

[0034] Among them, the feeding time of the first stage is 2 weeks, and the feeding conditions are flat feeding on the Internet, feeding 15 to 20 ducklings per square meter, feeding duckling pellets to the ducklings, adopting the method of free feeding and drinking for ducklings, and continuously lighting for 24 hours , The temperature of the duck house is kept at 30-32°C when the ...

Abstract

The invention relates to a duck sebum ratio prediction method. The method is characterized in that ducks are fed by stages, the feeding time and feeding condition at each stage are fixed, the growth condition of the ducks is recorded, the body sizes of the ducks are measured, the sebum ratios are obtained by slaughtering a few ducks, a multi-element optimal regression equation for calculating the duck sebum ratio is determined according to the growth condition of the ducks, the body sizes and the duck sebum ratios of a few ducks, and the sebum ratio of living ducks is rapidly and accurately predicted by using the multi-element optimal regression equation. Varieties are reserved selectively according to the serum ratios of the live ducks, the probability of elimination of superior duck individuals can be greatly decreased, and heredity estimation deviation can be reduced; meanwhile, the variety selecting and breeding cost is saved, and the variety selecting ad breeding efficiency is improved.

Description

technical field [0001] The invention relates to a duck skin fat rate prediction method, in particular to a duck skin fat rate prediction method for assisting meat duck breeding. Background technique [0002] The sebum rate of meat ducks has always been an important indicator in the selection and breeding of Peking ducks. Through a large amount of genetic breeding work over a long period of time, there have been significant differences in the sebum rate of Peking ducks. The traditional Peking duck sebum rate selection technology is based on the fat weight of the whole siblings to estimate the sebum rate of the remaining individual. This method requires the slaughter of a large number of live Peking ducks, which is time-consuming and laborious. In addition, some excellent individuals will be eliminated, resulting in Certain economic losses and genetic estimation bias lead to problems such as poor accuracy and slow genetic progress in seed selection.
