Effect of Addition of Humic Acid on broiler chickens diets on some the performance and carcass traits

Abstract

The experiment was carried out in the poultry  at Babylon to study the effect of Humic Acid in the diet on performance of Ross 308  Broiler chicks   During the first period which extended form the 1^st to the 6^th week The period From 20/1/2017  to 5/3/2017 . A total of 180 one day old chicks were used , chicks were allocated randomly in to 4 equal treatments, 45 chicks for each treatment , each treatment was included 3 equal replicates, 15 chicks for each one. Treatments were arranged as follow:

      The T1 treatments fed of  Basal diet (Control group) and  T2 treatments fed supplemented with Basal diet + 2.4 g/kg Humic Acids  and T3  treatments fed supplemented with Basal diet + 4.8 g/kg Humic Acids  and  T4  treatments fed supplemented with Basal diet + 7.2 g/kg Humic Acids  .

     Results showed the following ; Addition of Humic Acids in the diet Broiler chicks during the period (1-6) week of the experiment , had a significant effect ) P≤0.05 (on body weights of Broiler chicks and accumulative feed consumption , accumulative weights gain and feed conversion rate as compared with the control treatment. Addition of Humic Acid significant effect  on Carcass traits (Dressing percentage , The relative weight of the various Parts and Internal organs )  in comparison with control treatment .
