Abstract
The present study aimed to determine the effect of early feeding in Hatcher baskets & chick boxes with and without experimental material in broiler growth performance, carcass traits, blood parameters and economic efficiency. A total number of 1980 Arber Acres plus breed were incubated. Eggs were randomly divided into equal 4 groups of nearly similar means of egg weight (EW) in equal 3 replicates for each treatment. where eggs were hatched in suitable hatcher baskets with experimental materials, these eggs were hatched 1414 chicks and were sexed.
A total number of 420 day-old broilers male (AA+) chicks obtained were divided into four feeding trials. The Experimental diets were distributed as following: Control without feed at hatchery ;Boiled white eggs ; Pieces of fruit orange and Pre-starter diet were put at hatcher basket & 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 (MR). Also, European efficiency Factor; Carcass Parameters, Blood plasma constituents, Hematology and Economical efficiency (EEf).
Results obtained can be summarized in. Increasing body weight, feed intake due to early access to feed especially in OF and PS groups, meanwhile, Body weight gain, Feed Conversion Ratio and Growth Rate for early feeding groups BWE, OF and PS was significant 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 DR % ,DB %; TM% and BR% compared to chick groups fed control or BWE at the end experimental periods. Blood Hematology at different ages as affected by EF using different experimental diets, OF, PS and BWE are showed that higher in experimental treatments than control. from Economical point of view, It can concluded that, early feeding with OF and PS recorded the highest value of economic efficiency and relative economic efficiency % and improved performance followed by broiler early fed with BWE.
