Effect of using dry fat on performance, nutrients digestibility, carcass traits and blood constituents of broiler chicks
Abstract: An experiment was conducted to study the effect of using different sources of dry fat (Kem dry fat, KDF; calcium dry fat, CDF and Duna dry fat, DDF) at the rate of 4% either individually or in double or triple mixture in broiler diets on their growth performance, nutrients digestibility, carcass characteristics, tibia calcium and phosphorus retention, blood constituents and economical efficiency. A total number of 480 one day old Arbor Acres broiler chicks were used They were divided equally into 8 groups each of 6 replicates (10 birds/ replicate). The results revealed that the chicks fed KDF diet recorded numerically the best growth performance including final live body weight (LBW), body weight gain (BWG), feed intake (F1), feed conversion (FC) and performance index (P1) compared to the control diet and other treatments. Concerning digestion coefficients, also KDF diet showed numerically the highest CP and NFE digestibility, while KDF, KDF+ CDF and KDF+ CDF+ DDF significantly improved EE digestibility compared to the control diet. Results of organic matter (OM) digestibility and nitrogen balance (NB) % showed no significant differences among the experimental groups. It was noticed that all groups of chicks fed diets supplemented with all dry fat sources (either. solely or in combination) resulted in better carcass measurements than the unsupplemented group (the control). However, control group recorded significantly the lowest plasma values of total cholesterol, total lipids, high density lipoprotein (HDL) and low density lipoprotein (LDL), while it showed the highest values of plasma calcium and phosphorus compared to dry fat-supplemented groups. No significant differences among all dietary groups for tibia calcium and phosphorus percentages were observed.
It is concluded that supplementing broiler diet with 4% Kem dry fat (KDF) is beneficial to improve growth performance, carcass characteristics and return from feeding compared to the other dry fat sources.
