Influence of different dietary oil and fat sources on broiler performance

|
Abstract: An experiment was conducted to study the effect of substituting soybean oil (SO) with different sources of oils {corn (CO) or sunflower oils (SFO) } and fats, {camel fat (CFA) and margarine (MF)}, in addition to diet containing extruded full fat soybean (EX.FFS).on broiler performance, carcass characteristics, blood constituents, economic efficiency and to evaluate the nutritive value of the tested sources.
A total number of 192 unsexed 7-day old Arbor Acres broiler chicks were distributed into 6 treatments of 32 chicks each in four replicates (8 chicks per replicate ). The diets were formulated to be nearly iso nitrogenous (22% and 18% CP) and iso-energetic (3200 kcal ME/kg diet )at starter and finisher period, receptively. The results are summarized as follows:
1- Vegetable oils contained high amount of unsaturated fatty acids and low amount of saturated fatty acids and the reverse was noticed with animal fats. Sunflower oil contains high amount of linoleic acids C18:2
(67.4%) compared to the other tested oils.
2- Vegetable oils (SO,CO and SFO ) improved growth rate and feed conversion of broiler chicks compared to animal fats(CFA and MF ). However, chicks fed either SFO or extruded full-fat soybean recorded the best feed conversion. Mortality rate was not affected by different dietary treatments.
3- Insignificant differences were observed among different treatments in nitrogen balance, ME, and digestion coefficients of CP,CF,NFE, and OM, however, chicks fed extruded full-fat soybean were significantly more efficient to metabolizable ether extract ( EE) compared with the other treatments ( SO,MF or CFA).
4- No significant effect was observed on carcass characteristics or plasma total cholesterol concentrations due to oils or fats, however, camel fat or margarine showed significantly the highest total lipid values compared with vegetables oils (SO,CO, or SFO).
5- Sunflower oil gave the best economic efficiency (E.E) and the reverse was noticed with used camel fat, however, soybean oil gave close E.E for extruded full fat soybean.
In conclusion, chicks fed diets containing extruded full-fat soybean or sunflower oil performed better than those fed the other oil/fats sources.
