المستخلص The poulty industry is considered among of the most important element in the field of production of animal protein. This study aims to evaluate economical using of gamma rays and some feed additives on improving poultry hatchability and performance. This study included the following chapters: Chapter J : Contains the introduction and review. Chaptar II : Focuses on the production and consumption poultry in CA.R. -< ) • Chapter Hl.Contains the samples of study and six experimental methods including the lower doses of gamma irradiation on improving poultry hatchability and performance . l-The first experiment : Studied the effect of gamma rays radiation on hatchability in chickens. 2- The second experiment : Displayed the effect of gamma radiation on hatchability in Japanese Quails. 3- The third experiment: IlIustrats the effect of gamma rays on improving hatchability percccntagcs 01” chickens stored fertile eggs . 4 the fourth experiment : As essed the effect of gamma radiation on hatchability in quails which stored of J 2 0 C . 5- The fifth experiment: Evluated the effect of gamma radiation and feed additives on improving growth of broiler chicks. 6- The six experiment: Studied the effect of gamma radiation on improving the growth of Japanese Qualis . This study clarified that: ’ I-By using the dose 100 Rad of gamma rays the ratio of hatching for some classes of chickens which have given ahatching rate about 89.0 % in cornparsion to the control group in which the hatching rate mount to 79. 74% this rate has increased with the range of9.22 % . 2- By using radiation dose 25 Rad of gamma rays the ratio of haching of the Japanese Quails which is fertilized 94.6 % Summary instead of 79.29 % of the control ’group which on increase of 14..31%. 3- By using the dose 100 Rad of gamma Rays the hatching ratio of the fertilized stored chickens at adegree of 12 0 C has increased to 90.66 % with comparison the control group in which the hatching ration mantled to 76 % with an increase or 14.66 %. 4-By using the dose 100 Rad of gamma rays the hatching ratio of the Iertil ized stored Japanese Quails at a degree of 12 0 C has increased to 90 % with comparison the control group in which’ the hatching ration mantled to 78 % with an increase of 12% . 5- By using the dose 25 Racl of gamma rays with some feed adclitves the weight of the brid mounted 1161 . 22 gram while it to 1127 .89 gram. 6- By using the dose 25 Rad of gamma raise then the rate of the growth of the Japanse Quail increases with a rate of 10.7 gram furiliebrid. . Chapter IV: Economic analysis had been done on the cxperimcnts of study besides the analy is of investment in the field of radiation dose 100 Rad of gamma rayes before hatching the egge (poultry - quails ) increases the investment revenues in this field from 31.5 % to 57 % , also the use of gamma rays 25 Rad increases the investment revenues in the production of Broiler chicks from 14.83 % to 19.83 , more over the same doses increases the investment revenues in the field of growing Qualis from 29.88 % to 38. 89 % to 48.22 % . The study clarified that we can increase the production of hatching hen eggs by using the radiation dose (100 Rad ) frame 72 % hatching average to 89 .06 % and that leads to the increase of income of hatching hen eggs an the national level from L.E (6.3 Million to L. E 118 Million) . Also it leads to the increase of revenue on investment in this field from 31.5 % to 57 % . Also we can increase the revenue on national level in the field of hatching quail egge from L.E 1.6 milli n to L . 2.6 million with the increase of revenue on investment in this field 1).~ ’% to 36 n~ It is estimated that hatchapility is reduced 4%) for each day egge are stored after 5 day . This increase in hatching of stored egge would result in an increase in national incomefrome 1. 171.9 million , to 1. E 210 million with an increase in inv stment revenuce from 22.6 % to 48.5% for chicken eggs. Also we can increase the production or fattening poultry by u ing the does (25 rad) four limes 0 that th revenue or investment will increa e is th field of production of (Broiler chicks) from 14.83 % to 19.38 and the increase of the production of fattening quails by using the does (25 Rad ) as it is expected that the revenue will increase from L. E ( 17 153 ) to L. r: (2440 ). with the increase of revenue of in esuncnt in the field of fattening quails from 38.89 % to ~(8.22 % . The study clarified in th fourth chapter an economic study to establish a multipurpose radiation unit a the total costs of fundamentals mounted to L..E (5.3 Million) and the annual operation (work) expenses mounted to L . E ( 1.27 Million) , the peri h and the consumption of capital fundamentals were valued by (0.34 Million pounds) and the total in estment costs of the enter price were valued by (6.3 Mil1ion p und ). The enter price can be financed by capital mounts to ( 2.9 Million pound ). Along loan to be paid beck in five years time with an interest of 7 % with the sum of 340000 L . E and the financial flow but of this project in the frist year mounts 1.25 million L.E taking into consideration that the project will work with the half of its labour capacity, in the second year the financial Dow out mount to 1.65 million L. the taxes and will mount to 5.61 million L . E in the twenty, in the twent fifth par ofthe project. This study demonstrated that the cost of radiating of hatching egge broiler chicks according to the fundamental suppositions of the research increase of laboring a bout half the productive capacity of the radiation unit we conducted the cost of the radiating of hatching egges broiler chicks with a dose of 100 Rad mounts to 8.40 pount per ton, and the cost will decrea e to the half increase of laboring the radiation unit completey with allits capacity ( 4.20 pount / per ton) . before discounting the taxes were 23 % increase of taboring the unit with 50% . Chapter V : Contain the summary and rec mmendations. |
