Effect the Addation the Vegetative Growth for Diet and Exudates for drinking water of Pleurotus ostreatus Fungus on the Productivity and Physiological Traits of Broiler Chicken

The study was conducted in the field of poultry of the Department of Livestock - Faculty of Agriculture - University of Kufa For the period from 15 September to 20 October 2014. The purpose of the study was to test the effect of addition the biomass to the feed and exudates to the drinking water of Pleurotus ostreatus fungus on some productive and physiological traits for broiler chicks. A total of 360, one day old, Ross 308 broiler chicks were randomly allocated into eight treatment groups chicks in each treatment group were sub-divided into three replicates. The eight treatment groups were as follow T1 the control treatment without any additives. T2 Add Vegetative growth of P. ostreatus 25 g / kg feed. T3 Add Vegetative growth of P. ostreatus 50g / kg feed. T4 Add Vegetative growth of P. ostreatus 100 g / kg feed. T5 Add exudates of P. ostreatus 25 ml / liter in drinking water. T6 Add exudates of P. ostreatus 50 ml / liter in drinking water. T7 Add exudates of P. ostreatus 100 P. ostreatus / liter in drinking water. T8 Add Vegetative growth 50g / kg to feed and 50 ml / liter exudates of P. ostreatus in drinking water. The data showed the following results There are significant differences between treatments in the rate of body weight, where the results of the fifth week indicate superiority seventh treatment ( add exudates P. ostreatus rate of 100 / liter in drinking water) significant on all treatment where the average body weight of living (2287.5) g while the control treatment that amounted to (1809.1) g. Results shown the existence of significant differences in the rate of weight gain of the various treatment, where gave the seventh highest increase treatment weight gain weekly was (2133.7) g, while the increase of the weight weekly in the control treatment (1655.2) g. The highest amount of Feed consumption was in fourth treatment Where the average of Cumulative weekly feed intake at (3305.82) gm While the control treatment amounted (3045.11). the results of total feed efficiency indicate superiority treatment seventh significant on all treatment Where it reached (1.38).
