Effects of different vegetable oils and animal fat on performance and carcass traits of broiler chicks

This study was carried out at the Poultry Farm of Animal Sciences Department College of Agriculture Sciences, the University of Sulaimani to find out effects of different vegetable oil and animal fat on broiler performance. The aim of this research was to identify the effects of different sources of oils on productive performance of broiler chicks. The experimental period was from 8th March 2017 to 27th April 2017. An overall of two hundred sixty, one-day-old of Ross 308 broiler chicks were distributed randomly on five treatments (4 replicates each with (13 chicks/ replicate). The treatments include T1: Control (without oil and fat addition); T2: Canola oil (%4); T3: Corn oil (%4); T4: Animal fat (%4); T5: Sunflower oil (%4). During the period of study, three types of diets were applied: Starter diet (from the one to 20day of the study), grower diet (from 21 to 42 days of study) and finisher diet (from 43 to 49 days of the study). Results indicated that supplementation of diets with different types of oil and animal fat significantly (p<0.05) improved live body weight and weight gain and feed conversation ratio and feed intake and production index, at periods (1-49) day. However, the effect of different vegetable oil and animal fat had no significant effect on abdominal fat and dressing percentage at period (1-49) day.
