Effect of addition of different levels of humic acid to drinking water on productive and carcass characteristics of broiler chick

Abstract

This experiment was carried out at the which poultry farm of Babylon to study the effect of adding humic acid to the drinking water on performance of Ross 308 broiler chicks . The experimented the period from 20/1/2017 to 5/3/2017of birds age , A total of 135 one day old chicks were used in this experimented , chicks were allocated randomly in to 3 treatments, 45 chicks for each treatment , each treatment was included 3 equal replicates, 15 chicks for each one. 
 The treatments , were: -
 Treatment (T1) basal diet + fresh water without addition (Control group).
 Treatment(T2) basal diet + fresh water supplemented with Humic acids in ( 3.6 g/l liter water .
 Treatment(T3) basal diet + fresh water supplemented with Humic acids ( 7.8 g/l liter water .
 The results of this experiment indicated that supplemented of Humic acids in the fresh water during the period (1-6) week of the experiment , had a significant effect ) P≤0.05) on body weights rate of chicks and accumulative feed consumption , accumulative weights gain of the birds and significant effect) P≤0.05) of feed conversion rate as compared with the control treatment. Addition of humic acid has an significant effect of the birds ) P≤0.05) on the carcass traits of birds (The relative weight of the various carcass cuts and Internal organs ) in comparison to the birds of control treatment.
