Title: Effect of Feeding Domestic Pre-starter Diet on Broiler Performance and Carcass Characteristics
Author: Ahmed, Faisal Mustafa Eldsogi
Abstract: The effect of feeding local pre-starter diet (Anaam) on broiler performance, carcass an non-carcass characteristics was studied versus four imported pre-starter diets ( Nutristar , Grobel , Koudijs and Wafi ) and a starter diet as control . The study was conducted at Shambat area, University of Khartoum the premises of faculty of animal production in july 2014 . Employing a CRD, the six dietary treatments were assigned to one hundred and eighty day-old un sexed broiler chicks (Hubbard classic) in pens within an open sided poultry house . Each diet was replicated three times (pens) of 10 chicks each .Through six weeks experimental period, the pre-starter diets were fed only for the first week . For the rest of the duration, all of the six experimental groups of chicks were fed adlibitum the control diet . On weekly basis, data of feed intake, body weight gain and FCR as well as daily mortality rate were recorded throughout the experimentation period . On day 43, three birds from each replicate group were randomly chosen, leg banded, weighed, slaughtered , defeathered, bled and eviscerated for determination of carcass and non-carcass parameters. The first week data indicated that the locally produced pre-starter diet compared to the imported ones had significantly (p<0.05) negative effect on all performance parameters of broiler chicks . feed intake (110 vs. 138-164) ; growth rate (75 vs. 117-144); and FCR (1.47 vs. 1.10-1.31) . Also,the negative impact on feed intake was significant (p<0.05) in comparison with the control diet although the latter diet enhanced feed intake at the expense of feed utilization efficiency. The retardation effect of the domestic produced pre-started diet on broiler performance existed throughout the experimentation period, but at lesser degree with birds, increasing age which has been reflected by significantly (p>0.05) indifferent overall birds, performance, as well as carcass and most of non-carcass cha-racteristics. The low performance of the locally produced pre-starter diet necessitates further studies for its improvement .
