Abstract
The invention relates to a method for selecting a low-laying-rate hen in a feeding process of cage culture laying hens. The method comprises the following steps: dividing a plurality of groups of hens in a hen group, recording the egg laying quantity of each group for successive days, calculating the laying rate per day of each group, and calculating the group average laying rate of a group which does not achieve 100 percent laying rate; taking a group of which the group average laying rate is lower than a certain value as an alternative elimination group; observing the egg laying situations of individual hens in the alternative elimination group within several days; if the egg laying quantity of a certain hen within individual observation days is zero, eliminating the hen. According to the method provided by the invention, traditional selection of the low-laying-rate hen is converted from experience-based selection to data-based selection, and mass selection is transformed into small-scale directional selection, so that the accuracy rate, the efficiency and the convenience in hen selection are remarkably improved, not only a great number of feeding costs and expenses are reduced in time, but also a potential epidemic disease risk on other healthy hens in the whole hen group caused by a small number of hens in a disease status or a sub-health status is remarkably reduced.
Description
Technical field
The present invention relates to a kind of few selection method producing chicken, belong to the daily feeding management technique field of scale laying hen and laying breed.
Background technology
In layer breeding, the laying rate of laying hen is one of important indicator weighing chicken group's production efficiency, have impact on the height raising input-output ratio, directly determines the economic well-being of workers and staff of culturist.But in feeding process, chicken group always there will be the chicken that egg laying performance is relatively low, we average 3 days are laid eggs piece number lower than 1 piece and the continuous chicken do not laid eggs for 7 days be called and few produce chicken.Facts have proved, these chickens are when normal raising, and egg laying performance is difficult to improve, but still to take feedstuff, rearging cage position, epidemic prevention, the multinomial cost such as artificial, but it is with or without economic benefit less to produce, therefore reduces the input-output ratio that chicken group totally raises.
For raising chicken group's laying rate, raiser takes various measure, and a kind of is realized by the feeding environment of cultivation good quality and high output laying hen Creating Comfort, and another kind is to strengthen daily management, realizes by finding and eliminate widow product chicken in time.The former is system engineering, needs continuous Continual Improvement to realize, and consuming time longer, the latter then acts on substantially, instant effect, is used for remedying in time of the chicken group that egg laying performance is relatively low.
Few product chicken is from being divided into two types in appearance, and the first is the weak sick chicken of leprosy can substantially told by outward appearance, it is easy to being identified by people, and eliminate from chicken group, this is also the method that the superseded widow often used in present breeding layer chicken process produces chicken；The second is that appearance is healthy but the very low chicken even having no harvest of laying rate, is little to be identified by people, can only differentiate whether there is this kind of few chicken that produces jumpbogroup from the laying rate height of chicken group, but to find out and to eliminate that this few to produce chicken highly difficult.
Summary of the invention
In order to overcome the drawbacks described above under prior art, it is an object of the invention to provide the few selection method producing chicken in a kind of batterylaying feeding process, selecting of tradition few product chicken is converted to data type by the method by empirical, " mass-election " is changed into little scope " orientation " select, significantly improve the accuracy rate and efficiency and convenience of choosing chicken, particularly the aforementioned the second type widow not having external appearance characteristic can be produced chicken and pick out.
The technical scheme is that
The few selection method producing chicken in a kind of batterylaying feeding process, it is that the chicken of chicken group is divided into some groups, general with a cage for one group, the egg production recording each group in continuous many days, calculate often group laying rate every day, the group calculating group again average egg production of 100% laying rate will not occur, group average egg production is alternately eliminated group lower than the group of certain value, single the chicken of described alternative superseded group is individually observed some skies lay eggs situation, if individually observing the egg production of certain chicken in natural law is zero, then eliminate this chicken.
Choosing time of chicken should be selected in chicken and all open puerperal, particularly as follows: spring and summer carries out preferably in after chicken 25 week old season, autumn and winter season carries out preferably in after chicken 30 week old.
Natural law for determining the alternative superseded group of egg production recording each group continuously is preferably 5 days.
Each record time of laying eggs was preferably no more than 30 minutes.
Preferably by every every day the average egg production group lower than 50% alternately eliminate group.
Preferably being fixed on record egg production of identical time every day and collect egg, the record of egg production is preferably between morning 10-11 point.
Individually observe natural law and be preferably 2 days.
Often the chicken quantity in group is identical or different.
Often the chicken quantity in group identical and often the chicken quantity in group be preferably 4.
Chicken group all open puerperal, when laying rate is lower than standard laying rate, starts to select by above-mentioned chicken method of choosing, eliminate widow product chicken.
The invention have the benefit that
By the analysis of each cage laying rate, select, eliminate the widow producing degraded performance and produce chicken, direct saving feedstuff, raising, epidemic prevention, every feeding cost and the expense such as artificial.To save feedstuff; every few product chicken average specific health chicken raises 100 days less; within 110g/ days, calculate by feed consumption; average saving feed consumption 11kg after eliminating in time; chicken reduces cost 25 yuan; the ratio that in the chicken group of large-scale breeding, few product chicken on average occurs is about 5%, and therefore every ten thousand chickens can eliminate the few chicken 500 that produces, and saving feed cost is up to 12500 yuan.
Laying rate directly weighs the production performance of laying hen as quantitative index, but is commonly used to weigh the production performance of colony, and ignores its meaning in individual performance.The present invention, by the change of Continuous Observation list cage laying rate, sums up laying rate and the few corresponding relation producing chicken, directly according to laying rate index reduce few produce chicken select scope, significantly improve and few produce accuracy rate and the efficiency that chicken selects.
Selecting of tradition few product chicken is converted to data type by the present invention by empirical, or empirical converted to the mode incorporated experience on statistical data basis by pure, significantly improve and select precision and accuracy rate, can quickly choose few product chicken in the short period of time, especially can that accurately and quickly pick out the widow by virtue of experience almost not can not selected out and produce chicken, thus improving efficiency and the effect of choosing chicken.
The present invention utilizes laying rate index to adopt the method that little scope " orientation " is selected, can will need to select the few chicken group's scale down producing chicken to less than the 10% of original raising scale, compare " mass-election " and greatly reduce the colony choosing chicken, improve the accuracy rate and convenience selected.
Additionally; applicant further found that; along with widow produces the timely rejecting of chicken; what improve is not only the laying rate of scale laying hen chicken group; also significantly improve the health level of chicken group; the sickness rate of chicken group substantially reduces, and compared with the identical chicken group (comparison chicken group) being provided without this method, the sick chicken total amount eliminated in advance in laying period decreases about 50%.According to part anatomy experiment and theoretical supposition, the widow healthy for aforementioned the second appearance produces chicken, they are likely to be in sub-health state or the unconspicuous morbid state of outward manifestation, internal viscera is grown imperfection or there is sufferer, vulnerable to outside infective agent, internal be likely to survive have the pathogenic microorganism of relatively multiple types sum amount, it is easy to become starting point and the node of some pathophoresis, all the other healthy chickens in chicken group be only possible to and cause great potential epidemic disease to threaten.The widow that cannot reject for this traditional methods produces chicken by after adopting the method for the present invention to be rejected efficiently and accurately, hence it is evident that reduce the risk of the source of disease content in chicken group and healthy chicken flock.
Detailed description of the invention
The invention provides the few selection method producing chicken in a kind of batterylaying feeding process, it is that the chicken of chicken group is divided into some groups, general with a cage for one group, the egg production recording each group in continuous many days, calculate often group laying rate every day, for the group calculating group again average egg production of 100% laying rate does not occur, group average egg production is alternately eliminated group lower than the group of certain value, single the chicken of described alternative superseded group is individually observed some skies lay eggs situation, if individually observing the egg production of certain chicken in natural law is zero, then eliminate this chicken.
The Layer Production Performance standard alternately eliminating group can be determined according to practical factors such as the varieties and characteristics of chicken group, feeding environment conditions.In the present embodiment preferably by every every day the average egg production group lower than 50% alternately eliminate group, select the few standard of laying eggs producing chicken by 50% as Layer Production Performance.
The selection method of the present invention is general survey list cage chicken egg laying performance, and the widow eliminating egg production relatively low by record of laying eggs produces chicken.Select flow process to include:
1, determine that choosing widow produces chicken week old and standard
Choosing time of chicken should be selected in chicken and all open puerperal, namely chicken group lays eggs after upper peak, and concrete week old affects chicken group actual according to seasonal factor and opens product situation and determine, and spring and summer opens the upper peak of chicken group of product season relatively early, 25 week old reach peak value of laying eggs substantially, it is possible to start to select few product chicken；Autumn and winter season opens the chicken group producing evening and can postpone to 30 week old and selecting.
2, the preparation before selecting
The present embodiment is less with chicken group's scale, or the situation choosing chicken personnel amount sufficient is example.
First adjusting chicken group before selecting few product chicken, namely to all chicken packets of chicken group, often the chicken quantity in group can be identical, it is also possible to different, different also should keep quantity to be more or less the same as far as possible.In the present embodiment often the chicken quantity in group identical and often the chicken quantity in group be preferably 4, be adjusted to 4 by each cage chicken.Selecting few the previous day producing chicken, laying eggs before cleaning record, the time, at the morning or noon, namely lays eggs after peak period, is collected by egg complete with prestissimo within the shortest time, and all laying eggs hereafter selects record by charging to.
3, flow process is selected
3.1 personnel's packets
