J Vet Res., 22 (8):727-735, 2018. Capon is
the surgical removal of testes from roosters which promotes the accumulation of
intramuscular fat and affects fatty acid composition of poultry meat. We report
effect of caponization on muscle, liver and adipose tissue
fatty acid composition, lipid peroxidation and cholesterol content in breast muscle
of broilers. Groups of 30 male 1-d old commercial Cobb 500 broilers were caponized
at 21 days of age. Controls were 30 intact birds. Each treatment group
consisted of 6 replicates (cages) with 5 birds in each cage. Broilers were fed
commercial feed and slaughtered at 40 days. Major fatty acids in breast muscle
and adipose tissue were oleic (C18:1, n-9), palmitic (C16:0) and linoleic
(C18:2, n-6) and stearic (C18:0). Caponization did
not affect fatty acid composition of muscle, liver or adipose tissues or lipid
peroxidation of meat. However, we did find lower (P < 0.018) cholesterol (0.66 ± 0.02mg/ml) in breast muscle from caponized birds
(n=9) compared with 9 intact controls (0.77 ± 0.04mg/ml). Our findings
suggest that caponization does not affect free fatty
acid composition or lipid peroxidation but may reduce cholesterol in tissues of broilers.
