Description
Technical field
The invention mainly relates to cultural technique field, more particularly to a kind of method for improving free range chicken fertility rate of hatching egg.
Background technology
Free range chicken is also named hen, stupid chicken, refers to put the broiler chicken in hill woodland, orchard in a suitable place to breed, with it is resistance to it is thick raise, broodiness it is strong and
The characteristic, delicious meat such as premunition is strong.The egg nutrient of free range chicken enriches, and mouthfeel perfume (or spice) is tender, the fine and tender taste of chicken, and flavour is delicious,
It is nutritious, containing abundant protein, amino acid, vitamin, phosphorus, iron, copper and zinc, immunity can be improved with physical fitness,
Promotion intelligence development, tonifying kidney and benefiting sperm, fatigue-relieving, with the enhancing of people's health care consciousness, free range chicken is increasingly by the joyous of people
Meet, cultivation scale is also constantly expanding.
In the cultural method of present free range chicken, the embryonated egg of hatching egg can only achieve 80% or so, show the aquaculture cost of free range chicken
Write and improve, and there is presently no the method that can significantly improve free range chicken fertility rate of hatching egg.
The content of the invention
In order to make up the defect of prior art, it is an object of the invention to provide a kind of side for improving free range chicken fertility rate of hatching egg
Method.
A kind of method for improving free range chicken fertility rate of hatching egg, comprises the following steps：
（1）Breeder is selected：Selection is well-proportioned, strong, the maturity period the young chicken of health, and the quantity ratio of cock and hen is 1:14
~1:16, the distribution hen number of seminal fluid is improved, the rate of fertilization of hatching egg is improved, obtains breeder；
（2）Breeder is raised together with：Plant with 10 ~ 12 days before the phase, by cock and hen mixed breed, cultivation density is 2 ~ 3/m2, temperature
For 24 ~ 25 DEG C, humidity is 73 ~ 75%, and illumination is 1300 ~ 1400lx, and illumination 5 hours is dark 3 hours, and increase breeder is to environment
Adaptability, accelerates breeder heat, and the time is neat, is easy to concentrate semen collection and semen deposition, saves aquaculture cost, must raise together with breeder；
（3）Breeder point is supported：Plant with 4 ~ 5 days before the phase, eliminate underproof breeder, the quantity ratio for keeping cock and hen is 1:14~
1:16, the cock and hen that raise together with breeder are separately cultivated, cultivation density is 4 ~ 5/m2, temperature is 22 ~ 23 DEG C, and humidity is 75
~ 77%, illumination is 1000 ~ 1100lx, and illumination 3 hours is dark 1 hour, respectively feeding cock feed and food stuff for chicken laying, it is to avoid public
Chicken and hen self-copulation, the different feed of feeding, the pH of regulation breeder reproduction cell local environment is 7.6 ~ 7.8, reduction temperature
Degree, dim light frequent intermittent illumination extends light application time, accelerates the metabolism of breeder, enhancing adaptive capacity to environment and resistance,
The maturation of cock and hen reproduction cell is respectively facilitated, reproduction cell vigor is improved, promotes the raising of embryonated egg, score, which is supported, plants
Chicken；
（4）Cock semen collection：18 ~ 20 hours before semen collection, to cock gavage intestine cleaning liquid, free water removes the excrement in cock enteron aisle
Just, enhancing gastrointestinal function and resistance against diseases, semen collection take a step forward and reduce temperature, increase cock muscle tone, are easy to semen collection,
Progress is jejunitas, 2 ~ 3 hours before semen collection, is 16 ~ 18 DEG C by temperature adjustment, semen collection every other day 1 time adds seminal fluid weight immediately after semen collection
20 ~ 25% sodium bicarbonate solution, keeps the vigor of seminal fluid during cock semen collection, is well mixed, obtains seminal fluid；
（5）Hen semen deposition：It is molten for 12 ~ 14mg/L levodopa to hen gavage mass concentration 6 ~ 8 hours before hen semen deposition
Liquid, makes the of flaccid muscles of hen, reduces semen deposition difficulty, increases after adaptability of the seminal fluid to hen reproductive organs, gavage 5 ~ 6 hours
Use step（4）Obtained seminal fluid carries out semen deposition twice, semen deposition twice at intervals of 4 ~ 5 hours, improve rate of fertilization, obtain semen deposition female
Chicken；
（6）Breeder is conserved：After semen collection in 7 ~ 9 hours, to the vitamin c solution that cock gavage mass concentration is 0.12 ~ 0.14%,
Have additional nutrients, adjust the pH of cock, promote seminal fluid to be formed, it is ensured that the quality and quantity of seminal fluid during next semen collection, strengthen spermatid
Vigor, rate of fertilization is improved, based on cock weight, gavage amount is 3 ~ 4ml/kg, after second of semen deposition, to hen gavage quality point
Number is 3.4 ~ 3.6% calcium gluconate solutions, based on hen weight, and first time gavage amount is 5 ~ 6ml/kg, is spaced 28 ~ 30 hours
Afterwards, second of gavage amount is 5 ~ 6ml/kg, improves energy, and supplementing calcium element promotes the formation and differentiation of embryonated egg, must conserve public affairs
Chicken and maintenance hen；
（7）Hen is fed：Maintenance hen is individually fed, after semen deposition in 10 days, feeding feed is and step（3）Identical hen
Feed, temperature, which are 24 ~ 25 DEG C, humidity is that progress is normal after 78 ~ 80%, 10 days feeds to laying eggs, and improves seminal fluid to hen genitals
Official's adaptability, improves the survival rate of embryonated egg, must feed hen.

It is an advantage of the invention that：A kind of method for raising free range chicken fertility rate of hatching egg that the present invention is provided, method is simple, makes soil
The embryonated egg of hatching egg of a chicken is improved to 97.6%, hence it is evident that improve cultivation efficiency, and income improves 10.3%；Increase cock and hen
Ratio, improves the distribution hen number of seminal fluid, improves the rate of fertilization of hatching egg；Plant with 10 ~ 12 days before the phase, cock and hen are mixed and supported
Grow, proper temperature, carry out intermittent illumination, increase breeder accelerates breeder heat to the adaptability of environment, and the time is neat, is easy to collection
Middle semen collection and semen deposition, save aquaculture cost；Plant with 4 ~ 5 days before the phase, cock and hen are separately cultivated, it is to avoid cock and hen are certainly
Row mating, the different feed of feeding, the pH of regulation breeder reproduction cell local environment is 7.6 ~ 7.8, reduces temperature, dim light is frequent
Intermittent illumination, extends light application time, accelerates the metabolism of breeder, enhancing adaptive capacity to environment and resistance, respectively facilitates public affairs
Chicken and the maturation of hen reproduction cell, improve reproduction cell vigor, reduce the abnormal rate of sperm, promote the raising of embryonated egg；Adopt
First 18 ~ 20 hours of essence, to cock gavage intestine cleaning liquid, removes the excrement in cock enteron aisle, enhancing gastrointestinal function and resistance against diseases, adopts
Essence takes a step forward and reduces temperature, increases cock muscle tone, is easy to semen collection, adds sodium bicarbonate solution after semen collection immediately,
The vigor of seminal fluid during holding cock semen collection；6 ~ 8 hours before hen semen deposition, gavage levodopa solution makes the muscle of hen
Relaxation, reduces semen deposition difficulty, and increase seminal fluid carries out semen deposition twice to the adaptability of hen reproductive organs, improves rate of fertilization；Semen collection
Gavage vitamin c solution, has additional nutrients afterwards, adjusts the pH of cock, promotes seminal fluid to be formed, it is ensured that the quality of seminal fluid during next semen collection
And quantity, strengthen the vigor of spermatid, improve rate of fertilization；Hen gavage calcium gluconate solution twice, improves energy, supplements calcium
Element, promotes the formation and differentiation of embryonated egg；Feeding hen special feed in 10 days after semen deposition, improves seminal fluid to hen genitals
Official's adaptability, improves the survival rate and vigor of embryonated egg.
