Introduction and Objective: The aim of this study was to investigate the effect of potato waste on growth performance and carcass traits of broiler chickens.
Material and Methods: The study carried out in a completely randomized design with five treatments, four replications, 14 broiler chicks each. The experimental diets were consisted of three levels of potato wastes (0, 15 and 25%) and two levels of multi-enzyme (0 and 0.2%).
Results: Feed intake was not affected by the type of experimental diet during the growth period, the final period and the whole rearing period. Daily weight gain was not significantly different between the experimental groups but at the end of the experiment and the control group was better than other treatments. Growth conversion factor was lower in the potato-treated groups than in the control group. In the final period, the feed conversion ratio in the control group was significantly lower than the other experimental groups and this was also observed throughout the rearing period. It had no effect on carcass percentage, and relative weights of pancreas, liver, bursa Fabricius, spleen and heart. The ratio of intestinal length to live weight in birds fed 25% of potato lesions was higher than other groups. Potato lesions in the diet increased the relative weight of the gizzard and decreased abdominal fat compared to the control group (P<0.05).
Canclusion: According to the results of this study, the use of potato plus enzyme in relation to different levels of non-enzyme potato wastes had a positive effect on HDL cholesterol, intestinal morphometery and body weight gain in broilers.
