INTRODUCTION Dominant CZ firm offers for white egg layers feathersexing programme: DOMINANT LEGHORN D 229 feathersexed through slow-fast feathering K/k alleles of K gene. These original layers programme can be used in different - rural - organic - extensive - industrial - production conditions. He has high adaptability to possible feeding and environment conditions, answering common changes of conditions by selection of pure lines in original stocks in the last generations. Management guides for final hybrid stock will be oriented for cages technology and for litter technology in closed halls with controled lighting programme, because it is the most common producing system, garanting high performans, good health status and high quality of table eggs. We offer to Your attention common principles, which are recommend as optimal for the achievement of profit by producing of table eggs. If the other technology for the rearing or laying period of final hybrids stock is used, this management guides could be used as fundamental information, which could be apply in all types of environment. There must be tendency of a good breeder try to establish optimal conditions for his final hybrid stocks.next information can help You to reach it. Detail parameters of productivity of commercial stock DOMINANT LEGHORN D 229 is described in tables on pages 2, 7, 8 and 10. 1

2. PRINCIPLES OF PROSPEROUS REARING AND LAYING PERIOD I. Cleaning and washing of the rearing and production halls and also all technological equipments before delivery day. II. Disinsectization, desinfection, deratization of the rearing and producing halls after last stock in hall. III. Observance technological recommendations and requirements for commercial stocks DOMINANT CZ IV. Quality of rearing period determine the achievement of performance potential in laying period for productivity of table eggs with high quality. 3. LIVING SPACE FOR CHICKENS AND COMMERCIAL LAYERS It is optimal for rearing to keep chickens first 8 weeks in isolation from older birds. 1-10 weeks of age: 10 birds / m 2 of floor area Male / Female ratio: 15 males for 100 females 11-18 weeks of age: 8 birds / m 2 of floor area Male / Female ratio: 12 males for 100 females 19-78 week of age 5 birds / m 2 of floor area Male / Female ratio: 10 males for 100 females 4. FEEDING SPACE week 1-10 7 cm per individual week 11-78 12 cm per individual For feeding of Dominant CZ commercial stocks is recommended to use system ad libitum, without restrictions. Dominant CZ commercial stocks chickens usually do not require beak triming and are quiet, especially in fixed conditions without stress factors. 5.

DRINKING SPACE Week 1-10: 2 cm per individual and later increase to 3 cm per chicken, if it is used drinking system with niples, it would be better for first week place one drinker per 100 chickens equally in the whole place of rearing hall and use it no more than 1 week. In drinking system for chickens and for adult parents the watter must be available all the time. 7. BROODING TEMPERATURE Optimal temperatures for chickens reared on the floor (in the height of chickens) are: 1 st week 32-34 C 2 nd week 31-27 C In following weeks reduce by 2 C gradually till 20 C. The temperature near 20 C must be kept till the 18 th weeks and this temperature is optimal for the laying period as well. 8. LIGHTING PROGRAMME Light requirements are described in the lighting schedule attached on the page 6. This is the most important for the achievement of required production of table eggs in halls with controlled lighting programme to control number and weight of eggs between 20 th and 30 th weeks and to correct lighting programme especially between 22 th and 26 th week. It is better for obtaining higher weight of table eggs to keep lighting period for 13 hours. If weight of table eggs is optimal, could be better add every week half of hour of light and finally achieve 16 hours at 28 week. Between 22 th and 26 th weeks is possible to correct egg weight through correctures of lighting programme. Light intensity needed: 1-3 week 3-4 W / m 2 4-16 week 1-2 W / m 2 17-78 week 2-3 W / m 2 9. FEEDING PROGRAMME Minimally 4 periods with special feed mixtures: 0-4 week starter for layers 5-10 week grower for layers 11-18 week feed mixture for pullets 19-78 week feed mixture for layers Recommended requirements of nutrients and energy for commercial stocks of DOMINANT CZ programmes is described in schedule attached on the page 5. 10. WEIGHTING PROGRAMME It is recommended in the rearing period to weigh from 5 th week of age every week or 1x after 2 weeks. Well-balanced flock is, when 80 % of individual body weights has be in the interval +/- 10% of real average body weight. Important for the well balanced flock is ad libitum system of feeding, optimal concentration of chickens in hall and adequate dislocation of the technology in the whole area of hall. 3

11.VACCINATION PROGRAMME Routine vaccination programme must be discussed with local Veterinary Advicer and he must recommend optimal vaccination for Your place and actual epidemiologic situation in Your teritory. You must cooperate with Your hatching expert and discusse optimal Marek vaccine and finally to obtain information about maternal immunities of Your chickens. It is optimal, if every commercial stock should be under control of Poultry Veterinary Adviser for the control of imunity after vaccination, there should be a quick reaction in the case of infection in the flock. 12. TRANSFER OF PULLETS FROM THE REARING HALL INTO THE PRODUCTION HALL It is recommended to make the transfer in the age of 17 weeks optimaly and following principles must be respected: 1. Before the transfer tranquillizers should be delivered 2. No vaccination of poultry one week before and one week after the transfer 3. ransfer in early morning hours is recommended 4. Use suitable transport boxes only with optimal number of birds placed for preventing losses by crashing and stifling 5. Leave free space of 15 cm between the boxes during the transfer for good ventilation. Protect the front boxes from draught 6. The boxes must be under control during the transport 7. In the productin hall the drinkers with sufficient water supplies must be installed 8. It is recommended to use at least for the first week after transfer pullets the same feed mixture as in the rearing period 13. CLIMATISATION AND VENTILATION Sufficient aeration should be without draught, hall temperature should be from 18-24 C. Temperature under 15 C for longer period negative affects the quality of litter and the laying performance. Temperature higher than 30 C causes less feed consumption and less eggs productivity. It is optimal for the change of fresh air the quantity from 1-6 cubic meter of air per one hour per one kg of live body weight of chickens or hens, depenting temperature and humidity. Optimal humidity in the hall is from 40-60 %. 14. EGG COLLECTING BY LITTER TECHNOLOGY It is important for the collecting to clean eggs to minimalize eggs losed from floor. This eggs must be frequently collected. Nest must be distributed equable in the whole hall and one nest must be for 4-5 hens. 15. DAILY CONTROL OF EVERY SEPARATED FLOCK There must be every day controlle of mortality and health status in each flock and technological parameters temperature, ventilation, drinking and feeding. 16. INDUCED MOLTING DOMINANT LEGHORN D 229 cen be used for molting and eggs production in second cykle. It can be used for molting variety of methods and farmers can use own optimal method, which is best for him and for his specific farm and hall conditions. 4
