- This study was conducted to investigate the effect of feeding citrus wood charcoal on the performance, feed intake and feed conversion efficiency of broiler chicks. A total of 120 broilers of Habbard strain at 22 days of age were used in the experiment and were divided into four groups of 30 birds in each. Each group was divided into five replicates with six chicks per replicate. Birds in the experimental groups were fed citrus wood charcoal at rates of 0, 2,4 and 8% of the ration DM in replacement of yellow corn. The results showed that inclusion of citrus wood charcoal at rate of 2% had an effect on body weight gain, feed intake and feed conversion efficiency. The results indicated that the effect of citrus charcoal is an age dependent as it had no effect at ages of more than 29 days. However, inclusion of citrus wood charcoal increased birds abdomen fat.

- A total of 210 twenty-day-old broiler chicks were used in this programme to investigate the performance, feed intake, digestibility and visceral organ mass of broiler chicks fed with high level of olive pulp supplemented with two antibiotics: streptomycin and tylosin. The two antibiotics were added to supply 150 mg/kg of the active ingredient. Chicks which consumed the medicated dietshad more (p,0.05) gain compared to chicks which consumed the basal diet. However, streptomycin caused more (p,0.05) gain compared to tylosin. Antibiotics had no effect on feed intake. The chicks that consumed the antibiotics had heavier (p0.05) weights of edible, inedible organs and small intestine but lower weights of large intestine and cecum. The digestibility of dry matter, crude protein and nitrogen free extract increased (p0.05) in chicks fed with the medicated diets compared to the chicks fed with the basal diet. It is concluded that antibiotic supplementation had a positive effect on chick\'s performance and digestibility

- A total of 150 birds were used in this experiment in summer 2002 to investigate the effect of feeding starter diets for different periods on the performance and the economical advantages on broiler chicks. Birds were fed starter diets for two, three and four weeks prior to feeding the finisher diets. Birds fed the starter for four weeks had higher (p<0.05) average final weights, more (p<0.05) gain per day, more (p<0.05) feed intake and lowest (p<0.05) feed conversion efficiency. Feeding the starter for two weeks caused the lowest (p<0.05) cost of gain as opposed to other feeding groups. The results of the experiment showed that feeding starter rations for more than two weeks had no economical advantages according to the local starter feed prices.
