| Abstract | ||||
| The present study aimed to investigate the effect of early feeding in hatcher baskets and chick boxes with and without experimental materials on broiler growth performance, carcass traits, blood parameters and economical efficiency. A total number of 1980 eggs produced from Arber Acres plus (AA+) breed were incubated and randomly divided into equal 4 groups of nearly similar means of egg weight (EW) each with replicates for each treatment. Eggs were hatched in hatcher baskets with experimental materials. Only 420 day-old broilers male (AA+) chicks were divided into four feeding trials. The Experimental diets were distributed as following: control without feed at hatchery; boiled egg whites; (BEW), pieces of fruit orange (OF) and pre-starter diet (PS) were put at hatcher basket and chicks boxes. Live performance measurements for each feeding period were measured and/or calculated in terms of live body weight (LBW), body weight gain (BWG), feed intake (FI), feed conversion ratio (FCR), growth rate (GR), performance index (PI) and mortality rate. Also, European efficiency factor; carcass parameters, blood plasma constituents, and economical efficiency (EEf). Increasing body weight, feed intake due to early access to feed especially in OF and PS groups, meanwhile, BWG, FCR and GR for early feeding groups BWE, OF and PS were significantly improved compared to control. Performance Index and European efficiency factor were improved with early feed by OF and PS diets groups. Gastrointestinal tract length was increased by early feeding of OF and PS diets. Data indicated that chicks in OF and PS groups recorded the best values for dressing percentage , deboning ratio; thigh meat ratio and breast meat ratio compared to chick groups fed control or BEW at the end of experimental periods. Blood parameters as affected by EF using different experimental diets (OF, PS and BEW) showed higher values in experimental treatments than control. From economical point of view, it can be concluded that early feeding with OF and PS value for hatched chicks could be recommend for realizing best results of performance | ||||
