ØSecond, who are its brothers and sisters, and, if the information is available, what have been their breeding and productive performances? ØThird, with what individual or individuals is it at present mated, or has it been mated in the past?ØFourth, what were the results of these matings?•The first question is concerned with preceding generations, the second and third consider the individual’s own generation, while the fourth looks forward into the next succeeding generation.•Record of ancestral pairsØThe service most commonly associated with breeding records concern the successive matings of any given individual; that is, to easily and accurately trace its pedigree.ØIt is customary to look upon a pedigree as a list of ancestral individuals. Emphasis should be given to the fact that a pedigree is a record of ancestral-that is, parental-pairs running back through preceding generations.ØIn considering a given cockerel or pullet as a possible breeder, a knowledge of the breeding performance of each ancestral pair, as well as the productive performance of each ancestral female, is a matter of first importance.•Sib record.ØIt makes considerable difference in its probable value as a breeder whether a given bird is the one outstanding product of its parents, or whether it is simply one among several almost equally good brothers and sisters. ØUnfortunately, a single great performance, or an individual show bird of unusual excellence, may mean little in the line of breeding progress, but the chances greatly favor the bird with numerous brothers or sisters nearly or quite as good as he.Ø A good system of records will not only show, but should also call attention to an individual’s brothers and sisters.•Record of matingsØThe proper pairing of birds is the foundation of the breeder’s art and the basis of improvement through breeding. The breeding unit is the pair. ØDuring any given breeding season a promising male usually will be mated or paired with several females. And in successive seasons a given female may be mated with more than one male.ØIn order to give proper consideration to the pairing of birds during a given season, one should be in a position to give intensive study, in the case of all individuals previously bred, to the results of former matings. ØIn order to do this there must obviously be available a list or record of all matings.•Progeny record.ØIn contemplating a pair of birds as possible parents, a consideration of their individuality, their ancestry, their sibs, and previous mates are of the greatest importance. Upon them hopes are built, but predictions are uncertain. ØThere is but one sure basis of judging a bird’s breeding value from the standpoint of heredity, and that it is the breeding of it. ØAfter a given pair has been mated, and progeny gotten and grown, really accurate judgments can be formed. The test of efficient mating is the character of the progeny.ØAs suggested above, the progeny test, from the standpoint of a parental pair, is a look forward into the next generation, as the study of the pedigree is a look back into past generations, and of sibs and mates a survey of the contemporary generation. ØThis forward look gives sounder and more dependable information than the other two combined.ØThe fourth service which breeding records should give, therefore, is to show the progeny of any pair in a group so that they may be readily available for study.•临时性记录临时性记录Ø手工记录手工记录: :根据育种方案事先设计好一些统一、规范的记录根据育种方案事先设计好一些统一、规范的记录表格，将测定结果直接填入表格中。

分析软件Breeding records and breeding practice•In breeding practice the managemental unit is the pen, the breeding unit is the pair. The incubating unit is determined by the size of the incubator tray, and the time unit involved is usually one breeding season.•Economic considerations generally preclude the mating of as many males as females, and one male is usually penned with several females, thus constituting a breeding pen.•While pen records are considerably better than no records and give some information regarding the breeding performance of the males, providing always that but one male is used in a pen, they do not give the information necessary for the best progress, or, in some cases, even the maintenance of a high level of excellence.•From the standpoint of breeding, a pen is a group of matings or pairs, with the male a member of each pair. •The breeder's search, with the help of progeny records, is for fortunately mated pairs, and when these are discovered there is a really fairly firm foundation on which to build. •It is necessary to trapnest all mated females during the breeding season, so that the mother of each egg may be identified, and of marking the egg so that the identification may be preserved.•It is in turn necessary to sort out the eggs of each female before hatching, and arrange means of identifying each chick that hatches with its dam, which also identifies it with its sire through the record of matings. •Each step in this series of operations must be a matter of record if the whole purpose of the record is to be served.•A further consideration in breeding practice is the fact that matings are usually made for an entire season. •Because of the great desirability of setting eggs soon after being laid, the progeny of any one pair does not appear as a single seasonal litter as in the case of swine, but are hatched periodically throughout the season. •Thus full brothers and sisters of a single season may have varying hatching dates, and individuals hatched on one date are likely, because at different stages of maturity, to be more desirable as breeders the following season than those hatched at some other date.•It is, therefore, highly desirable to make the dates of hatching a part of the record.Steps in a complete breeding record•There are five essential steps in the yearly cycle of keeping a complete flock breeding record which will furnish the information discussed above. These are:1.The recording of each mating made;2.Making a record of each breeding male’s pedigree and progeny; 3.Making a record of each breeding female’s pedigree, production, and progeny; 4.Marking each egg of each breeding female as it is laid, and pedigree hatching it; 5.Marking and recording the chicks at hatching in such a way as to identify them with their parentsRecord of matings•In order to make a record of matings, the individual breeders must be marked.•The mating record itself is simply a list of the birds in any given breeding pen, and is most useful for future reference.•A convenient form for keeping the record of a single mating is designed.•The reverse side of the form is the first page of the “Progeny and Sib Record” of that pen. This record will be discussed later.Record of matingsSire’s record•The sire’s record should furnish at least three sorts of information:(1) his ancestry (or pedigree); (2) his progeny; (3) notes on his individuality and breeding performance.•A convenient blank form for the pedigree is shown in figure 3. It is well to give his wing-band number as well as his leg-band number, as shown in the upper right-hand corner.•The breed of which a given individual is a representative should always be indicated on the pedigree of any bird sold, and it is good practice to have it on all pedigrees.•The pedigree of a male used as a breeder should be completely recorded for at least four generations back if possible. When the daughters mature and are leg-banded, their numbers may be listed in numerical order in the spaces provided on the reverse side of the“Sire’s Record”. The egg records of the respective daughters are entered later as they are completed.Dam’s record•The dam’s record should furnish the same information concerning each female as does the sire’s record, and in addition give her production record.•The blank form for the purpose consist of an “Individual Egg Record” as shown in figure 5, with spaces for her ancestral records, her daughter’s records, and for further notes on the reverse side as shown in figure 6.•The “Individual Egg Record” gives an opportunity to see and study a whole year’s production with its cycles and pauses and is to be urged in place of simply keeping monthly and yearly totals.•A further sheet is needed for each succeeding year’s production.Dam’s recordPedigree hatching•On the eighteenth day the eggs of each mated female are all put in a separate sack, small tray, or wire basket, so arranged that the chicks cannot escape after hatching and can be identified with their mother by the numbers on the shells.•In so incubating eggs that the chicks out of each hen may be identified.•The reason for this is that a proportion of the fertile eggs which die during the period of incubation. No dead eggs should be left to be carried through the pedigree hatching process.Hatching record•The record of a given female’s performance as a breeder is quite incomplete unless it includes her hatching record. •Sterility or a tendency toward sterility on the part of a male will usually be noticed because it affects the hatching record of a whole breeding pen. •But low hatching power of the eggs of an individual female are likely to go unnoticed unless the relationship between the number of eggs set from each individual and the number of chicks hatched during an entire season is a matter of record.•A convenient blank form for keeping such a record is shown in figure 14.Marking and recording the chicks•After the hatch is over, the next step is to mark the chicks. This is done by a small numbered band placed on the leg or in the wing.•Usually when leg banding is practiced, the band is later changed from the leg to the wing, where it remains during the life of the bird. •At the time the chick is banded the number on the band should be recorded with its mating number.• If the chicks are recorded by matings in the Progeny and Sib Record, the first page of which is the reverse side of the Mating Record, it is necessary only to record the wing-band number in the column of the proper dam.•It will save time by using a blank form called the “Chick Index,” and the wing-band numbers entered serially in advance.家禽育种记录家禽育种记录•蛋鸡育种基本记录项目及要求：蛋鸡育种基本记录项目及要求： 1.系谱孵化表：要求系谱清楚，可计算种蛋系谱孵化表：要求系谱清楚，可计算种蛋受精率和孵化率受精率和孵化率 2.雏鸡登记表：可辨认个体及其父母，雏鸡雏鸡登记表：可辨认个体及其父母，雏鸡重及特点重及特点 3.育雏育成鸡表：生长情况、体重变化育雏育成鸡表：生长情况、体重变化 。
