Description
Technical Field
The invention relates to the field of poultry breeding, in particular to a method for breeding egg laying pigeons in a single cage.
Background
The pigeons belong to a couple of birds, once the male pigeons and the female pigeons are successfully matched, the loyalty is high, and the pigeons are born together and undertake the tasks of hatching and feeding the young pigeons except special cases (one party dies). Early researches find that the pigeons cannot automatically ovulate and need to be mated and stimulated by male and female pigeons to lay eggs. Later researches show that under the condition of no male, after two female pigeons love each other and simulate mating, the two female pigeons can lay eggs, so that a breeding mode of breeding the egg-laying pigeons in a double female pairing mode is born in production. The egg yield is more than 1.5 times of that under the mode of 'male-female pairing'. However, the pigeon breeding cage has the same size as that of the male-female pair because the double-female pair pigeons still have the mating behavior. On the other hand, because two female pigeons are simultaneously raised in one cage, which one of the pigeons produces each time the egg is laid, the judgment cannot be made, and partial low-yield pigeons cannot be found out due to the high yield of the spouse; also in future egg pigeon breeding, there is no way to implement selection according to individual egg production, slowing down genetic progress.
The culture space is further saved, and the culture quantity is increased; meanwhile, the individual egg yield is accurately recorded, and the breeding efficiency is improved.
Disclosure of Invention
In order to realize the single-cage breeding of the egg laying pigeons and improve the breeding density and the egg yield selection accuracy, the invention provides a method for breeding the egg laying pigeons in a single cage.
In order to achieve the purpose, the method for feeding egg laying pigeons in a single cage comprises the following steps:
(1) young pigeons enter a flying shed and then are subjected to group flying feeding, wherein 15% -25% of young male pigeons are placed in each flying shed, male pigeons and female pigeons are fed in different rooms, and the male pigeons are fed in different rooms at intervals of the female pigeons.
(2) Young female pigeons are raised to 5.5-6 months old, transferred from a flying shed to a pigeon-laying house to serve as laying pigeons for raising, the laying pigeons are raised in a single cage (namely 1 cage of 1 pigeons) in the pigeon-laying house, and not less than 5% of male pigeons are scattered in each pigeon-laying house.
Preferably, in the step (1), the parent pigeon is identified before the child pigeon is transferred to the flying shed, for example, the parent pigeon is worn with an identification foot ring.
Preferably, in the step (1), 18% to 22% of young pigeons, for example, 20% are placed in each fly shed.
Preferably, in the step (2), the length, width and height of each pigeon house are 35-45 cm, 20-30 cm and 25-35 cm respectively; a flat bottom egg laying nest is arranged in each pigeon cage and is positioned on the bottom net of the pigeon cage. For example, the length, width and height of the pigeon house are 40cm, 25cm and 30cm respectively.
Preferably, the radius and the height of the flat-bottom egg laying nest are 8-12 cm and 3-7 cm respectively. For example, the radius and the height of the flat bottom egg laying nest are respectively 10cm and 5 cm.
The invention has the beneficial effects that:
(1) in the pigeon breeding house, female pigeons are bred in a single cage, the volume of the pigeon breeding cage is only 1/3 matched with two female pigeons, a large amount of breeding space is saved, and the breeding amount of the pigeon breeding house with the same area can be increased by 1/3;
(2) the female pigeons are fed in a single cage, the egg laying condition of each laying pigeon can be timely and accurately known, the pigeons with low laying rate can be timely found and treated or eliminated, the high-yield pigeons are supplemented, the feed waste can be reduced, and the production efficiency is improved;
(3) in breeding, the female pigeons are raised in a single cage, the egg laying condition of each laying pigeon can be accurately recorded, high-yield pigeons are selected and reserved according to the yield, and the breeding process is accelerated;
(4) compared with male and female paired egg laying pigeons, the female pigeons are fed in a single cage, so that the burden of feeding male pigeons is saved, the cost is reduced, and the production benefit is improved;
(5) the elimination of male and female paired pigeons is generally carried out in pairs, the single cage breeding of female pigeons can be carried out by single cage precise elimination, and the single cage breeding death and elimination rate of female pigeons is low;
(6) the female pigeons are raised in a single cage, so that complicated pairing work is not required, and the operation is simple and convenient;
(7) the female pigeons are fed in a single cage, the behaviors of mating and fighting between the double female pigeons and the male female pigeons are avoided, and the breakage rate of the pigeon eggs is reduced;
(8) the double-female and male-female paired pigeons spit and feed food mutually, and share a feeding trough and an egg laying nest, so that the risk of infectious diseases is greatly increased, and the incidence rate is higher than that of the single-cage feeding of the female pigeons.
Detailed Description
In order to clearly understand the technical contents of the present invention, the following examples are given in detail.
Example 1
Young pigeons which are mixed and fed in the same batch of flying sheds are subjected to sex identification, and the female pigeons are worn with red foot rings. At 5 months of age, 30 young pigeons and 60 female pigeons are randomly selected. Wherein 30 male pigeons are matched with 30 female pigeons; in addition, 30 female pigeons are fed in a single cage, and the cages are completely shielded by a paper board, so that the pigeons cannot be in physical contact with each other. The pigeon houses are distributed, and the feeding management is the same. And recording the egg laying condition of each cage. And collecting blood from the wing vein of female pigeons transferred to a flying shed (2 months old), before pairing (4 months old before cage), male and female pairing (5 months old after pairing and before egg laying), and single female pigeons (5 months old, 6 months old, 7 months old), respectively, and separating serum to determine gonadotropin releasing hormone (GnRH) and gonadotropin inhibiting hormone (GnIH).
The hormone assay results were: the levels of two hormones of young pigeons and female pigeons at 2 months are lower; with the increase of age, until after the female pigeons leave the fly shed and before cage pairing (4 months of age), the change of serum GnRH hormone level is small, the GnIH hormone level is greatly increased (P <0.01), and the GnIH of the female pigeons is greatly increased relative to the GnRH hormone level (P < 0.01). And (3) male and female pairing: the serum GnRH hormone level of the female pigeons before post-laying (5 months old) is extremely remarkably increased (P <0.01), the GnIH hormone level is in a descending trend but does not reach the remarkable level, and the GnIH is extremely remarkably reduced relative to the GnRH hormone level (P < 0.01). A single female pigeon: the GnRH hormone level in the serum is obviously increased at the age of 5 months, and then the GnRH hormone level reaches the obvious level even though the GnRH hormone level fluctuates up and down until the age of 7 months; the GnIH hormone in the serum is still at a higher level at the age of 5 months, and is reduced remarkably until the age of 6 months; serum GnIH levels were at higher levels relative to GnRH hormone levels by 5 months of age, and did not decline very significantly until 6 months of age. Compared with the change rule of male and female paired pigeons and single female pigeons, the change of GnIH/GnRH level can be triggered by paired stimulation, and the change of the relative level of the two hormones is an important factor for regulating and controlling the laying of female pigeons. Whether paired or single female isolation pigeons, the serum GnRH hormone level rises significantly at 5 months of age, possibly related to the sexual maturity of the female pigeons at this stage. The initiation of bird reproduction is controlled by hypothalamus-pituitary-gonad axis (HPG), GnRH is a neuropeptide secreted by hypothalamus, and plays a role in promoting development and ovulation of bird follicles, and GnRH stimulates the anterior pituitary of the pituitary to secrete Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH) by binding with GnRH receptor on the pituitary, thereby promoting gonad maturation, sex hormone secretion and sexual behavior. The GnIH hormone acts as another neuropeptide in the hypothalamus, with a completely opposite effect to GnRH. The sound of bird singing also plays an important role in reproductive function, and bird corrus sound-specific neurons are found in the anterior optic lobe and anterior hypothalamus of birds, and are capable of receiving centrally-specific androgenic or androgenic corrus sounds, which indirectly stimulate the increase of LH levels in the pituitary. In the experiment, the single female pigeons are isolated by the partition plates so that the single female pigeons cannot be in physical contact, the pairing behavior is avoided, but the single female pigeons can still contact the singing sounds of other pigeons in the surrounding environment, and the singing sounds of the same kind finally stimulate the development of sexually mature single female pigeons. In the experiment, although the paired pigeons and the single female pigeons show the rise of the serum GnRH hormone level when reaching sexual maturity, the serum GnIH of the female pigeons before egg laying (5 months old) is extremely obviously reduced relative to the GnRH hormone level after pairing, while the serum GnIH of the single female pigeons at 5 months old is still at a higher level relative to the GnRH hormone level and is extremely obviously reduced until 6 months old, so the single female pigeons start to lay late.

And (4) conclusion: the single-cage breeding of the egg laying pigeons is feasible, the egg laying number is slightly lower than that of male and female paired egg laying pigeons, but the breeding of the male pigeons with the same number is not needed, and the breeding cost is greatly reduced. Laying pigeons are raised in a single cage and are laid for about 7 months later.
Example 2
After sex identification, the female pigeons are worn with red foot rings. 1000 young pigeons in the same batch, wherein 200 male pigeons and 800 female pigeons are transferred to a flying shed group for flying and feeding. 100 male pigeons are distributed in each room, and 200 female pigeons are distributed in each room according to the sequence of female, male, female, male and female … …. And (5.5) at the age of month, randomly selecting 96 male pigeons and 288 female pigeons, transferring the pigeons into an egg laying pigeonry, and starting an experiment. And when the pigeons are put into cages, three groups of male-female pairing (G), double-female pairing (S) and single-female pigeons (D) are arranged, each group is provided with 4 repetitions, and each repetition is 24 pairs (for a single-female pigeons group, each repetition is 24). The pigeon houses in each group are distributed, and the feeding management is the same. And (4) recording the egg laying condition, recording the egg laying number and the egg breaking number of each cage of pigeons independently, and counting the average value of each group in each month on the basis of single cage data.
The egg breaking rate is equal to the number of broken eggs/egg yield multiplied by 100 percent
The dead elimination rate is the eliminated pigeon number/caged pigeon number multiplied by 100 percent

And (4) conclusion: the egg laying persistence of the single-cage breeding egg laying pigeons is equal to that of the male and female paired egg laying pigeons, the egg laying amount is slightly lower than that of the male and female paired egg laying pigeons, but the breeding cost of the male pigeons is greatly reduced because the male pigeons do not need to be bred; the egg laying stability and the egg laying amount of the single-cage breeding egg laying pigeons are superior to those of double-female paired egg laying pigeons. The death rate of laying pigeons raised in a single cage is only half of that of male-female paired laying pigeons and double-female paired laying pigeons.
Example 3
After sex identification, the female pigeons are worn with red foot rings. 2000 children pigeons in the same batch, wherein 400 male pigeons and 1600 female pigeons are transferred to a flying shed group for flying and feeding. 100 male pigeons and 200 female pigeons are respectively arranged in each room; the number of the rows is 10, and the rows are 2, and each row is arranged at intervals in the order of female, male, female, male and female … …. And 5.5 months old, randomly selecting 80 male pigeons and 1500 female pigeons, transferring the male pigeons and the female pigeons into an egg laying pigeonry, and feeding the pigeons in a single cage. The male pigeons are scattered and distributed among the female pigeons in a scattered manner, and the more uniform the distribution in the pigeonry, the better. And (4) recording the egg laying condition, recording the egg laying number and the egg breaking number of each cage of pigeons independently, and counting the average value of each group in each month on the basis of single cage data.

Unit: day,%
And (4) conclusion: in the pigeon laying period, the effect of laying eggs by feeding large-scale female pigeons in a single cage is good. But a small number of male pigeons are needed to continuously stimulate the female pigeons through sound. Compared with the single-cage breeding of the small group of female pigeons, the single-cage breeding of the large-scale female pigeons has equivalent egg laying effect and slightly low death and culling rate.
In this specification, the invention has been described with reference to specific embodiments thereof. It will, however, be evident that various modifications and changes may be made thereto without departing from the broader spirit and scope of the invention. The description is thus to be regarded as illustrative instead of limiting.
