Problems solved by technology

In summer, the outside temperature is high, and the normal cooling process cannot be realized. The temperature in the house is often 5 degrees higher than the actual temperature of the chickens, and the feed intake of the chickens is seriously affected. Therefore, the weight of the summer chicks is qualified at 5-9 weeks. The rate is not up to standard

Embodiment 1

[0046] S1) The weight screening of 1-day-old chicks, elects a large weight greater than 35g, and then observes the chick body in the daily chicks and randomly samples 3 chicks to check the ovaronia absorption, and squeezed out of the ovals at three days. Two chicks were absorbed, and high-temperature breeding, the above high-temperature brooding was found that the above-mentioned situation was 1 degree, the temperature drop was 0.5 degrees daily, to 14 days, and recorded the 14-day chick body weight average value of 125g. This week's standard weight is 120g;

[0047] S2) The chick is 5-9 weeks to heat the temperature, non-summer.

[0048] S3) were ILT immunity to 9-week-old chicks, one week before immunization at intervals of 1 day in respiratory auscultation, confirmed that no respiratory symptoms, and found a higher risk of secondary infection, the use of doxycycline and wonderful Thai streptozotocin mixed feeding to prevent secondary infection on the day of vaccination and improv...

Embodiment 2

[0052] S1) for screening for weight 1 day old chicks, the chicks weighing more than 35g select a breeding cage, chickens were observed daily after physical random sampling and 3 chicks necropsy examination yolk absorption, chicken yolk malabsorption does not appear , but was found in 4 of weak chicks, brood temperature take the temperature of the date brood was found that the above temperature by 0.5 degrees brooder houses, cooling rate of 0.5 degrees per day, to 14 days of age, and body weight was recorded 14 chicks an average of 119g, this week, the standard weight is 120g;

[0053] S2) 5-9 weeks off the chicks warm, non-summer.

[0054] S3) were ILT immune to 8-week-old chicks, one week before immunization at intervals of 1 day in respiratory auscultation, confirmed that no respiratory symptoms, and found a lower risk of secondary infection, the use of doxycycline and wonderful Thai streptozotocin mixed feeding to prevent secondary infection on the day of vaccination and improv...

Embodiment 3

[0074] This embodiment is a summer feeding

[0075] S1) for screening for weight 1 day old chicks, the chicks weighing more than 35g select a breeding cage, chickens were observed daily after physical random sampling and 3 chicks necropsy examination yolk absorption, and at the time of sampling the yolk 4 malabsorption two chicks, brood temperature take the temperature of the date brood is found out that the temperature increase of 1 degree brooder houses, after cooling rate of 0.5 degree per day to 14 days, and recorded as the average weight of chickens 14 126g, this week, the standard weight is 120g;

[0076] S2) chicks 5-9 weeks off temperature, the temperature during removal gradually determined by the minimum tidal volume ventilation transition to determine the amount of ventilation by "apparent temperature" mode, and recording the average weight of chickens at 9 weeks 936G, week standard weighs 720g.

[0077] S3) for 9 weeks old chicks to infectious laryngotracheitis immuniz...

Abstract

The invention relates to a breeding method for egg breeding hens. The breeding method comprises the following steps: S1) carrying out weight screening on one-day-old chicks, feeding the chicks with qualified weight into a cage for breeding, observing the chicks every day within two weeks of feeding the chicks into the cage, and randomly selecting the chicks for dissecting and checking the egg yolk absorption condition; S2) carrying out heat supply stopping on the chicks in the fifth week; S3) carrying out infectious laryngotracheitis immunization on the chicks in the 8th-9th weeks, carrying out respiratory tract auscultation before immunization to confirm that no respiratory tract symptom exists, feeding the chicks with antibiotics to prevent secondary infection, and increasing the house temperature on the day of inoculation; and S4) adjusting the breeding density in the 14th weeks. According to the breeding method provided by the invention, corresponding means are implemented in different growth stages of different egg breeding hens, so that the weight of the egg breeding hens in each stage in the growth process can reach the standard.

Description

Technical field [0001] The present invention relates to poultry culture techniques, and more particularly to an egg-rated chicken breeding method capable of ensuring a variety of body weight. Background technique [0002] Egg hns have different sides of the organ growth and development of each growth stage, and weight is an external manifestation that reflects the overall development of the organism. The pass rate of body weight does not meet the standard means that the organ development is not up to standard, and it is necessary to have a serious impact on the production performance of the egg period. [0003] The applicant of the present invention is summarized by the mass weight gain law of egg seed chickens, and the body weight is subject to the feeding period and the feeding season has the greatest effect. [0004] Zhouling is the first influencing factor of body weight. Combined with practice, it is found that the weight of the chicken is 1-2 weeks old, 8-9 weeks and after ...
