Effect of different sources of fat powder and phosphorus in diet on growth performance and carcass characteristics of male broiler

This study was conducted to determine the effects of three different fat powder sources on growth performance and carcass traits of male broiler chickens reared in cages with 4 floors to 42 d of age. 120-day-old broiler chicks (Ross 308) were randomly assigned to one of the six treatments with four replicates based on a randomized complete block design with a 3×2 factorial arrangement. The fat sources include fat powder with plant origin, pure palm and plant – animal mixed were used. Sources of phosphorus include di-calcium phosphate and phosphoric acid were used. Daily feed intake, Daily gain and feed conversion ratio not affected by the type of fat sources from 10 to 42 days (p>0.05). Two sources di-calcium phosphate and phosphoric acid in average daily feed intake, daily gain and feed conversion ratio were not significantly different (p>0.05). Daily feed intake, daily gain and feed conversion ratio was not affected by the interaction between sources of fat and source of phosphorus from 10 to 42 days (p>0.05). Dressing percentage, breast, thigh, abdominal fat and liver in birds fed the different sources fat powder was not significant (p>0.05). Compare treatments in terms of the cost of feed to one kilogram of live weight showed that diet containing fat powder with plant origin in the entire production period was more expensive than the other two sources. The results showed that, there is no significant difference between the different sources of fat powder on performance and carcass traits of birds (p>0.05
