| titleOfInvention | Breeding method of laying hen variety with low excrement water content |
| abstract | The invention discloses a breeding method of a laying hen variety with low excrement water content, which comprises the following steps: 1) continuously observing the water content of the layer chicken manure and recording; 2) counting the grading condition of the water content of the layer excrements of each family; 3) grading the laying hens according to the grading condition, eliminating the laying hens with low scores, and selecting the remaining male and female chickens to establish a pure family; 4) repeat operations 1) -3) for G1, G2, and subsequent generations. By adopting the breeding method of the chicken breeds provided by the invention, the water content of the excrement of the laying hens in each generation is obviously reduced, after the breeding of 3 generations, the number of the laying hens with higher excrement water content is less than 5% of the total number, and the problem of high excrement water content of the laying hens can be effectively solved, so that the feed utilization efficiency is improved, the medicine use is reduced, the death rate of the laying hens is reduced, and the income of a large number of laying hen farmers is increased. |
