Abstract

A total of 600 quail chicks from 3 lines (White-W, Light Brown-Lb and Dark brown-Db) were brought from Department of Animal production, Faculty of Agriculture, Sallah-Aldein University, Erbil, KR-Iraq. This work was conducted at the Poultry Farm of Animal Production Department, College of Agricultural Engineering Sciences, University of Duhok, Kurdistan region, Iraq. The aim of experiment was to investigate the productive performance of three quail lines under Duhok region environment during 2016. The birds were reared in cages and the feed was supplied manually and submitted ad libitum. The following characters were studied during growth and egg production stages: Live body weight (BW), body weight gain (WG), feed intake (FI), feed conversion ratio (FCR), sexual maturity, egg weight (EW), egg number (EN), egg mass (EM), mortality rate, fertility and hatchability. The main results from the present study could be summarized as follow: BW trait was highly significant differed (p<0.01) among the studied lines at 1, 2 and 3 weeks old; and was differed significantly (p<0.05) at 4 weeks old, where brown lines surpassed white ones. Other traits (WG, FI, FCR, EW, EN, EM, fertility and hatchability) didn’t differ significantly (p>0.05) among the studied lines at all studied ages. The lowest mortality rate was recorded to Lb line (0 %). As conclusion, the Lb line had the best productive performance.

Abstract

A total of 288 pullets, at the age of 18 weeks, were used to investigate the effect of replacement soya bean protein (SP) in ration, with animal protein (AP) on laying eggs performance of pullets up to age 34 weeks, and the economic efficiency. Pullets were distributed randomly to four diet treatments with four replicates. The treatments were, T1: Normal protein sources (AP and SP), it was considered as control; T2: 25% of normal ration replaces with SP source; T3: 50% of normal ration replaces with SP source; and T4: 100% SP (vegetable ration). The results showed that vegetable treatment (100% SP), recorded significantly the lowest values of live body weight (LBW), egg weight (EW), egg number (EN), hen day percentage (HD) and feed conversion ratio (FCR). The economic analysis showed that control treatment surpassed all other treatments.
