The way the content of breeding birds

 

(57) Abstract:

Usage: in the poultry industry for the maintenance of breeding birds, for the fastest valuable breeding lines and crosses, their perfection. Throughout the biological cycle of egg production of laying hens kept in individual cages with limited space not less than 1.5 m2with Autonomous watering and feeding, manufacturer hoisted to the layers with a periodicity for every 4 - 5 days with sexual load per manufacturer 4 to 5 hens, 1 Il.

The invention relates to a process and devices for the maintenance of breeding birds.

There is a method group housing of breeding birds and their selection for mating in direct and reverse combinations, the definition of General and specific combining ability and mating choices of (paternal and maternal lines), the abstraction of linear young, carrying out of selection for increased compatibility, selected as analog. [1].

There is a method of creating breeds of poultry, consisting in an individual in vivo selection for feed conversion, containing from 1 to 21 days of the conclusion together with 21 to 49 day - in individual cages with weekly definition is Rania breeding birds using habitats in the house, including floors and deep litter, selected as a prototype. [31].

The disadvantage of these methods [1, 2, 3] is their low efficiency because of the impossibility of predicting the compatibility of lines without experimental crosses, reducing the accuracy of the accounting productivity, high labor intensity. If this is not possible with high reliability to assess the origin of the offspring, the assessment of the compatibility of the lines requires a considerable time. The inefficiency of the method is associated with additional costs for planting birds in the nest at a certain time of day, usually at night, to determine individual egg production and productivity, but also in the DIN that the bird twice is under stress. In addition, when the coupling manufacturer with laying some specimens may show selective field capacity, which reduces oplodotvorennogo eggs, and therefore productivity.

The aim of the invention is to increase the efficiency of the method of the contents of breeding birds.

This objective is achieved in that in the method of maintaining breeding birds using habitats in the house, including floors and deep litter, the difference is located to the limited space of not less than 1.5 m2, self-watering and feeding, manufacturer hoisted to the layers with a periodicity for each 4 to 5 days sexual load per manufacturer 4 to 5 hens.

The advantage of the proposed method of maintenance of breeding birds is as follows. Throughout the biological cycle of egg production of laying hens kept in individual sections with independent watering and feeding, which improves the accuracy of the account in selection for feed conversion in the individual control of the content and productivity of breeding birds. In addition, for an accurate assessment of egg production and productivity of laying hens, and to exclude the factor electoral capacity for it is implanted manufacturer intervals for each of not less than (4 - 5) days from the sexual load of not less than (4 - 5) hens per manufacturer restriction of space habitats not less than 1.5 m2. At the same time combines the combined conditions of habitat: breeding mating with the individual assessment of each individual. The proposed techniques allow selection with 100% accuracy to determine the origin of the seed.

However, based on the foregoing, we can conclude that podsazhivanie polowy 1.5 m2and simultaneous monitoring of individual feed intake meets the criterion of "novelty", "inventive step" and "industrial applicability".

The drawing shows the layout of the individual cells and nests to host hens and manufacturer.

The way the content of breeding birds is as follows.

The bird put 6 goals (5 hens and 1 manufacturer) each hen put in a separate cage 1 forming section 2, consisting of five cells 1. Five cells 1 or section 2 form a breeding chamber 3. Section 2 is placed in a two-row array 4. Depending on the size of the premises and of the formation of breeding nests 3 place the appropriate number of arrays 4. As the source data for the operator on the corresponding array made of two-dimensional symbol M is the sequence number of the section, N is the number of cells. The operator uses the legend, maintains records of feed intake. At the same time in each section 2 operator podzuzhivaet manufacturer to the next hen with a frequency of 4 to 5 days with sexual load per manufacturer 4 to 5 hens, in addition, maintains records of egg production by alandotu, significantly shorten the duration of the selection process, to improve the accuracy of individual metering of feed intake and productivity.

FIELD: agriculture, in particular, poultry farming.

SUBSTANCE: apparatus has axial-flow draft fans arranged in longitudinal-vertical coordinate planes extending through middle portion of doubled cage batteries. Guiding screens mix air flows while hazard gasses generated by birds and released from bird dung are fully assimilated. Before being discharged from poultry house, contaminated air is disinfected with disinfecting solution sprayed by nozzles positioned above each draft fan, to thereby disinfect air delivered into ambient air.

EFFECT: improved sanitary and hygienic bird keeping conditions, reduced consumption of power, increased efficiency in ventilation of space inside cage and disinfection of contaminated air at poultry house outlet opening.
