First, light program. At the end of June, first the male and female groups were grouped to begin the dark period, respectively, and the lighting time was reduced from 17 hours before the egg production in June to 8 hours per day. The total implementation lasted from 2 months until the end of August; the pheasants were noted during the period. Heat protection work.
Two months later, a new light program was started, and it was appropriate to increase it by 1.5 hours per week, gradually returning to 17 hours of light per day. Special attention should be paid to the fact that male pheasants must implement dimming procedures with female pheasants at the same time, otherwise the male pheasants will not have the ability to copulate.
Second, feeding. During the dark period, it can be fed with the pre-preparation material of commercially-available breeder chickens, plus corn, sorghum, rice, wheat and other roughages to ensure the supply of green feed. Before the end of the dark period until the laying of eggs, in addition to the early feeding of breeding chickens, the intake of animal protein should be increased. During the laying period, commercially available chicken eggs should be fed, and appropriate additions such as soybean meal, fish meal, bone meal, and methionine should be added. , lysine, compound multidimensional and other nutrients. At the same time, supply sufficient green feed to ensure drinking water hygiene.
Third, gregarious. When the dark light period expires, the male and female can be grouped together, and the male-female ratio is 1:4.
Fourth, prevention of disease. Full group injection of Newcastle disease when gregarious] is a vaccine, pay attention to environmental health, keep quiet, weekly with a "hundred poisonous" chicken spray disinfection.
Fifth, guarantee the temperature. In winter, it is relatively cold. It is necessary to artificially create a spring environment for the pheasants. It is advisable for the temperature to be not less than 10°C.
Through the above measures, the pheasants can lay eggs again approximately at the end of October. Each pheasant can produce as many as 180-200 eggs per year, and the fertilization rate of eggs can reach 90%. This application of off-season production technology greatly improves the pheasants. The production performance.
The normal production period of pheasants is from February to August, and the peaks of egg production are mainly concentrated from February to June. With the increase of temperature, although the egg production has not been stopped in July-August, the number has decreased rapidly, and the fertilization rate of eggs is also increased. Extremely low, that is, at the end of June it is time to change the feeding method.
