Abstract

A total number of 128 laying pullets and 16 cocks of Matrouh local strain at 140 days of age (20-24 weeks) were randomly divided into four treatment groups (32 females and 4 males / group) in completely randomized design. The injections were carried out once a week for a month (4 times injection) before sexual maturity from 20 to 24 weeks of age. The 1st treatment group of pullets was injected with a saline solution 0.9% and was considered as a control group. The 2nd group, was administrated into the mouth, with 0.2 ml of distill water, which containing 200 μg royal jelly (RJ) /kg BW. While, the 3rd and 4th groups were injected subcutaneously with 0.2 ml of saline solution 0.9%, which containing 200 μg/Kg BWof each of gibberellic acid (GA3) or testosterone (Ts), respectively.          The obtained results revealed that the final body weight, daily feed consumption (DFC) and feed conversion ratio (FCR) of Matrouh pullets treated with 200 μg Ts, or GA3, /kg BW, as well as egg production rate (EPR), egg mass (EM) and egg weight (EW) were improved significantly (P≤0.05) as compared with the control at the whole experimental period (24-48 weeks of age) compared to the control group. The lowest mortality rate (MR) 9.38 and 12.50% was significantly with Ts and RJ treated groups, respectively. While, the highest MR (%) was 18.75 and 15.63% recorded in GA3 and control groups, respectively in laying pullets, during the total period (24-48 weeks of age). Moreover, egg shape index and egg albumin index were significantly (P<0.05) increased for pullets injected with 200 μg GA3 and Ts/kg BW, respectively when compared to the control group, during the period from 24-48 weeks of age. However, results obtained revealed that treated pullets with Ts and RJ increased significant (P<0.05) egg albumin weight % than the control group in the same period. The best economic efficiency and the highest net return were recorded with GA3 followed by the RJ group, while the control group recorded the lowest values during the whole experimental periods (20-48 weeks of age). Conclusively, pullets treated with 200 μg GA3 or RJ /kg BW during pre-sexual maturity of age (20-24 weeks) were recommended for improving most of the productive  performance, as well as egg quality, highest net return and economic efficiency of  Matrouh local strain during summer season in Egypt
