This experiment was conducted to investigate the effect of adding biochar to the diet and litter on growth performance, gas concentration, hock burning and dermatitis in the foot pads of broilers. In the experiment, 300 One day old chicks were randomly distributed to 5 treatments 3 replicates each treatment , with (20) birds .T1: as control treatment. T2: (2) kg biochar / 100 kg feed). T3: (4 kg biochar l / 100 kg feed). T4: (2 kg biochar / 100 kg litter). T5: (4 kg biochar / 100 kg litter) . The results of the statistical analysis of the average live body weight and feed conversion factor of broilers showed a significant superiority of the treatments with added biochar to the feed compared to the treatments with added biochar to the litter and the control group. While the results for ammonia gas NH3 levels, the hock burn and footpad dermatitis suggested that the addition of biochar to the litter treatments produced the best results compared to the biochar-added diet group and the control group.

This experiment was conducted to investigate the effect of adding biochar to the diet and litter on growth performance and broilers the hock burn and footpad dermatitis. In the experiment, 300 One day old chicks were randomly distributed to 5 treatments 3 replicates each treatment , with (20) birds per replicate and with an average weight (39.7) g. T1: Without adding biochar in the diet and litter. T2: (2) kg of biochar / 100 kg of diet). T3: (4 kg of biochar l / 100 kg of diet). T4: (2 kg of biochar / 100 kg of litter). T5: (4 kg of biochar / 100 kg of litter) . The results of the statistical analysis of the weekly diet consumption rate indicated a significant superiority of the treatments of adding biochar to the diet over the treatments of adding biochar to the litter and the control group . While the results of relative humidity, level ammonia NH3 level indicated that adding biochar to the litter treatments recorded the best results compared to the group adding biochar to the diet and the control group. As for the results of the microbial characteristics, it was shown that the treatments of adding biochar to the diet recorded the best results compared with the group adding biochar to the litter and the control group, which recorded a decrease in the number of colon bacteria and an increase in the number of lactic acid bacteria. While the relative humidity results indicated that adding biochar to the litter treatments recorded the best results compared to the group adding biochar to the diet and the control group.
The aim of this study is to evaluate biochar as a food additive and a positive stimulant of the intestinal flora in maintaining the health of the broiler digestive system. Besides, due to its absorbent properties, it can reduce the moisture content of the litter and improve the overall environment of broiler breeding halls.

This study was conducted at Department of Animal production farm College of Agriculture University of Tikrit from 6/12/2017 until 21/2/2018 (77days) . Sixteen Awassi lambs were used, aged 4-5 months and average weight 23.38±0.14 Kg . Lambs were divided in to four groups (four lambs at each group) according to their weight, treatments distributed randomly into the groups.Individual feeding was used which included four concentrate diet with different levels of biochar (0% ,1% , 2% and 3% ).Statistical analysis results showed that there was a significant increase (P<0.05) in the final weight for second group (1% biochar) compared with fourth group, also result showed a significant increase (P<0.05) for second group in the average daily gain and final body gain and feed conversion ratio compared with third and fourth groups. Also significant increase (P> 0.05) in the second group in hot and cold carcass weight and in the percentage Dressing based on hot and cold weight, relative to live weight as well as empty body weight and in Rib-eye muscle area compared with the other groups.
