Dried poultry droppings as a non¬conventional feed ingredient in broiler diets (with 10 tables) [electronic resource]

Includes references.

Dried poultry droppings (DPD) was incorporated in broiler chick diets at levels of 5, 10 and 15% as a non protein nitrogenous source in four experimental trials. Two hundred, one day old Arbor acre broiler chicks were randomly distributed into ten equal experimental groups of 20 chicks each. A control group in the first trial was fed on three diets, the starter, grower and finisher, based on com and soybean meal and free from dried poultry droppings. In the other three trials, three groups were assigned for each. The first group in each trial was fed three phases diets containing 5, 10 and 15% DPD, while in the second group, the grower and fmisher diets were both had DPD and in the third one, only the finisher diet was contained DPD. The growth performance, body weight development, weight gain, feed intake and feed conversion efficiency were assessed. The chicks appeared to be affected differently by the dietary regimens. In the first group of 5, 10 and 15% DPD test trials in which chicks fed on DPD throughout the whole experimental period, there were a reduction in the growth rate by about 8, 27 and 36 % than control respectively, consuming less amount of food and had high feed conversion indices (2.92, 3.37 & 3.21) compared with 2.66 in control group. In the second group of all trials where birds raised on DPD during growing-finishing periods, feed consumption and weight gain were less than control group. In the third group of all treatments in which DPD was limited to the finishing period, growth rate was nearly less, while more feed consumption resulting in a feed conversion indices slightly higher than the control one. Thus, It could be concluded that, the cost of poultry diets can be reduced by using DPD up till 15% of the chick diets through the finishing phase without any adverse effect under the experimental condition.
