Abstract
Experiment was conducted to evaluate effects of different fat sources on breast and thigh meat chemical composition and
fatty acid proile in broilers. Treatments were 1) DF1: basal diet + soybean oil; 2) DF2: basal diet + chicken fat; 3) DF2: basal diet +
tallow; 4) DF3: basal diet + tallow and lard, and 5) DF5: basal diet + lard. Addition of different fat sources had no signiicant impact
on relative organ weight (P>0.05). Breast meat crude fat content was suppressed in DF1 and DF5 relative to DF4 (P<0.05). Total
SFA content was downtrended and total PUFA content was elevated in DF1 relative to other groups for both breast and thigh
meat (P<0.05). Total MUFA content did not differ in breast meat, however, it was lower in DF1 and DF3 compared to DF2, DF4
and DF5 (P<0.05). The n-3 PUFA was not affected by fat sources in breast meat, whereas it was elevated in DF1 relative to DF3,
DF4 and DF5 in thigh meat (P<0.05). Breast and thigh meat n-6 PUFA was improved in DF1 in comparison to DF2, DF3, DF4 and
DF5 in thigh meat (P<0.05). Ratio of PUFA to SFA upgraded in DF1 and DF3, and downgraded in DF2, DF4 and DF5 for breast
meat; and upgraded in DF1 than other groups for thigh meat (P<0.05). Breast and thigh meat n-6 to n-3 PUFA was upgraded
in DF1 group compared to other groups (P<0.05). To sum up, results indicated that dietary fat sources with different fatty acid
content can signiicantly inluence the breast and thigh meat composition and fatty acid proile without negative impact on the
relative organ weight. Where DF1 group exhibited better result based on fatty acid proile and lower breast meat fat content which
can be preferred for quality broiler meat production.

Introduction
A considerable elevation of global meat consumption (62%) has
been reported in the last 50 years, with a signiicant increase occurring
in developing countries (three-fold since 1963) and the largest
occurring in Asia (Commodity Analysis, Informa UK, 2012). he
highest global chicken meat intake is 11.8 kg per person, whereas in
Asia it is 6.4 kg per person, where the forecast average meat intake for
China, Japan, the Republic of Korea, hailand, Indonesia and India is
11.1, 15.8, 15.4, 13.9, 4.5, and 3.1 kg/person, respectively (Commodity
analysis, Informa UK, 2012). Among diferent meats, poultry is irmly
and continuously increasing worldwide due to its low-price relative to
other meat, as well as its healthy aspects. Currently, consumers are more
concerned about their food, especially nutritional aspects. Among the
nutritional aspects of food, lipid content and fatty acid proile are the
most important factors. Chicken meat contains a high protein and low-
fat content and deliberated as the principal source of polyunsaturated
fatty acids (PUFA) with paramount concentration of n-3 PUFA [1,2].
Fatty acids play a signiicant role in the health aspects of humans, with
long chain fatty acids being beneicial for maintenance of metabolic
disorders, as well as for development of the brain and retinal tissue [3-
5]. Food containing higher amounts of PUFA are considered functional
and beneicial for the prevention of coronary heart disease and other
chronic diseases [6,7]. he most desirable issue inluencing the poultry
industry is the improvement of performance while developing higher
carcass and meat quality, higher meat yield and lower abdominal fat
with better composition [8]. he fatty acid content of broiler meat
depends on the type of diet intake by the birds. Pigs and broilers fed a
sunlower based diet, which contains linoleic acid, show substantially
elevated levels of linoleic acid and arachidonic acid in the meat [9,10].
It has also been reported that the fatty acid content of poultry, especially
the PUFA (ecosapentanoic acid, C20:5n-3; and docosa hexanoic acid,
C22:6n-3), can be improved by the addition of oily ish byproducts
[11]. Replacement of ish oil with vegetable oil has resulted in a lower
level of long chain n-3 fatty acids, eicosapentaenoic acid (EPA) and
docosahexaenoic acid (DHA), and higher levels of the C:18 fatty
acids, oleic acid, linoleic acid and linolenic acid in tissues of several
aquatic studies [12,13]. Plant fats generally contain higher amounts of
PUFA, while animal fats are composed of relatively higher SFA levels.
Diferences in the fatty acid composition of the fats will vigorously afect
the digestibility and performance of birds. In addition, the composition
of dietary lipids is important to chickens because it dictates the actual
extent to which it can be utilized as a source of metabolizable energy
[14]. Fats with a higher proportion of unsaturated lipids are more
easily absorbed than those that may undergo synergism between fat
compositions [15-17].
Studies have been conducted to improve the PUFA content in
chicken through dietary addition of fat and oil sources that contains
PUFA or linoleic acid [9,17], as well as dietary feed additives such as
probiotics, prebiotics and natural plant materials [18-22]. However,
PUFA tends to be oxidized as it is the irst target for the free radical
strike upon initiation of lipid peroxidation [23]. Several studies have
investigated fat sources of livestock and poultry to investigate their
performance, digestibility, and carcass characteristics [8,17,24-26].
here are many plant and animal fat sources with large variations in
fatty acid proile or other aspects of their nutritional composition; on
the other hand, due to genetic improvement of broiler strains it urges
paramount importance of continual research on both the basal and
feed additives research. Fatty acid composition can be an important
benchmark for the quality of carcass that can potentially be inluenced
