NUTRITIONAL EVALUATION OF OIL REFINING BY-PRODUCTS AS A SOURCE OF ENERGY AND ESSENTIAL FATTY ACIDS IN BROILER DIETS I. UNTRADITIONAL FAT SOURCES IN BROILER DIETS
One hundred and twenty five-day–old unsexed broiler chicks (Ross 500) were used to evaluate the nutritive value,some plasma components, carcass traits, some bone measurements, and economic values of traditional oil and oils and fats refiningby- product sources supplemented to its starter, grower and finisher diets starting from 7 to 35 day old. Chicks were reared in broiler fitted batteries.The tested oils/fats sources were soybean oil (SBO), palm oil (PO), dry fat (DF), fatty acids (FA) and distillated fatty acids (DFA) at levels of 2, 3 and 4% in the starter, grower and finisher diets, respectively. Chemical analysis of the experimental treatments indicated that SBO have a higher content of oleic and linoleic acids. The DFA contained a middle level of linoleic acid and higher level of linolenic acid. Results indicatedthat, different experimental treatments didn’t have any significant effect on chick performance including feed intake, body weight gain or feed conversion ratio at any period or overall period of the experiment. The same result was noted at 35 day-old for carcass traits, tibial measurements except for tibia width (mm) which recorded significant higher value with SBO and DFA treatments compared with the other treatments. The DFA treatment exhibited the highest CP% of breast meat among the experimental groups, while the highest E.E. percent of breast was recorded for both PO and DFA treatments. A significant higher percent of CP and ash content of tibia was recorded for FA and DF treatments, respectively. The CP% of drumstick meat was higherfor both DFA and FA treatments compared with the other experimental treatments. Regarding to plasma components, a significant higher values of triglycerides were recorded for FA and DFA groups; total cholesterol for DF and DFA groups, total protein for SBO, DF and FA treatments; GOT for PO and DFA treatment; GPT for DFA treatment andphosphorous for DFA group.
