“…The increased levels of fatty acids C24:1 n9, C18:3 n3, C18:3 n6, and C20:2 n6 are desirable for protection against atherosclerosis and thrombotic disease (MULVIHILL, 2001). On the other hand, the levels of the fatty acids C18:1 n5, C19:1 n9, C18:1 n4, C18:1 n3, C20:1 n11, and C20:1 n9, which were less common and/or appeared at lower levels in beef, were not altered by castration or castration age.…”

This study aimed to evaluate the cholesterol content, α-tocopherol and fatty acids in the meat of Nellore young bulls or steers castrated at different ages, 13 or 18 months. The animals were confined for 100 days and slaughtered at 22 months of age. The experimental design was completely randomized with three treatments, using 12 repetitions. The levels of palmitic acid (26.39%), stearic (24.39%), myristic (3.01%) and total saturated fatty acids were not altered by sexual condition or castration age. Oleic was the fatty acid with the highest average participation in the meat (34.54%), and lower content in the meat of young bulls in relation to the castrated. The content of total unsaturated fatty acids was lower in the young bulls in relation to castrated at 18 months, which did not differ from castrated at 12 months. The content of total polyunsaturated fatty acids was increased by elevation of the castration age, being similar between young bulls and castrated at 18 months. The ratio ω6/ω3 was not altered by sexual condition or castration age. Castration at the beginning of the finishing period increases the content of beneficial fatty acids to health in relation to castrated in the first third of backgrounding.

ResumoObjetivou-se avaliar o conteúdo de colesterol, α-tocoferol e ácidos graxos da carne de machos inteiros ou castrados em diferentes idades (13 ou 18 meses) da raça Nelore. Os animais foram confinados por 100 dias e abatidos com 22 meses de idade. O delineamento experimental utilizado foi o inteiramente casualizado com três tratamentos, utilizando-se 12 repetições. Os teores dos ácidos palmítico (26,39%), esteárico (24,39%), mirístico (3,01%) e ácidos graxos saturados totais não foram alterados pela condição sexual e/ou idade à castração. O oleico foi o ácido graxo com maior participação média na carne (34,54%), com menor participação na carne dos inteiros em relação aos castrados. O teor de ácidos graxos insaturados totais foi menor na carne dos inteiros em relação aos castrados com 18 meses, que não diferiram dos castrados aos 12 meses. O teor dos ácidos graxos poliinsaturados foi aumentado pela elevação da idade à castração, sendo similar entre inteiros e castrados aos 18 meses. A relação ω6/ ω3 não foi alterada pela condição sexual e/ou idade à castração. A castração no início do período de

“…CLA has the same chain length as linoleic acid, but in CLA the double bonds are conjugated, rather than methylene-separated as they are in linoleic acid. Conjugated bonds are separated by one single carbon bond rather than two or more bonds (Mulvihill, 2001). The bonds in CLA can be either trans or cis configuration.…”

“…Among the essential polyunsaturated fatty acids, conjugated linoleic acids (CLAs) are the most sensitive to oxidation. CLAs are a group of geometric and positional isomers of linoleic acid (C18:2 n-6), including cis-trans, cis-cis and trans-trans fatty acids (cis-9, trans-11; trans-9, trans-11; trans-10, cis-12; trans-10, trans-12; cis-9, cis-11; and trans-9, cis-11) (Fritsche and Fritsche, 1998;Mulvihill, 2001). C18:3 n-3 and C18:2 n-6 are incompletely hydrogenated in the rumen.…”
