This study was carried out at the poultry experimental station, Technical
Institute of Agriculture, Damascus University, Kharbo. 270 of Japanese Quail
birds, one day of age were divided equally into 3 similar groups (90each). Every
group comprised
of 3 replicates of 30 each, each replicates contained 10 cages.
Birds were housed and managed under similar conditions throughout the
experimental period which lasted from the 8 to 22 weeks of age. The birds were
fed on rations recommended by NRC and contained 1, 0.65 or 2 of DLmethionine
g/kg of ration in the first (the control), second and third groups
respectively. Results showed that using ration contained 2g DL-methionine/
1kg of ration gave a significant increase in egg weight, production and
economical efficiency value as compared to the other used rations.
The influence of Red Paprika and Local Safflower in the diets on yolk color
was studied in two experiments of ٨ and ٥ weeks using ٩٠ and ٢٤ laying hens,
respectively; Loghorn hybrids of Lohmann brown and Hy- Lain Brown strain,
were used.
In the f
irst experiment, yellow corn was substituted totally by rye and wheat
and ٤ different amounts of paprika or safflower were tested (٠,٢, ٠,٣, ٠,٤ and
٠,٥٪). In the second experiment the effect of sweet red paprika or hot red
paprika in the diet (٠,٥٪) on yolk color or some of production parameters was
studied.
