ABSTRACT
Serum biochemical and meat fatty acid profile of
different chickens were studied. A total of 144 mixed sex matured chickens of Cosmopolitan
(C), Improved Horro (H), Cosmopolitan♂*Improved Horro♀(CH), Improved Horro♂*Cosmopolitan♀ (HC), Indigenous (L) and
Koekkoek (KK) were used to determine serum biochemical, of which 36 chickens were also
used for fatty acid profile study. Completely randomized design in 6 × 2 factorial arrangements was set up. Serum biochemical and fatty acid
profiles were determined by Roche/Hitachi cobas c 501 and gas liquid
chromatography (GC) procedures, respectively.
There were significant differences (P ≤ 0.001) in Total cholesterol
(TC), Triglyceride (TG), Low-density lipoprotein (LDL) and High-density
lipoprotein (HDL) among genotypes and between sexes. HDL was inversely related
with TC, TG and LDL. Male had significantly higher (P ≤ 0.001) TC, TG, LDL but
lower HDL than female. SFA, (Myristic, Pentadecanoic and Palmitic acids) had
significantly (P < 0.05) varied among genotypes. However, Margaric (P ≤
0.01) and stearic (P ≤ 0.001) acids were significantly different between sexes.
Myristoleic and Palmitoleic acids significantly vary (P ≤ 0.05) among genotypes
and between sexes. Oleic (P ≤ 0.01) and Eicosenoic (P ≤ 0.001) significantly
influenced by sex. Moreover, Linoleic had significantly (P ≤ 0.01) affected by
genotypes. Nevertheless, α-linolenic
acid significantly (P ≤ 0.01) varied between sexes. The serum biochemical
differed across genotypes and between sexes. The difference in the number of
carbons, double bond and position of the double bond could affect fatty acid
profile among genotypes and between sexes. Chicken products with higher level
TC, TG, LDL and SFA might affect human health problems. It could also be
interesting topic for future studies.
