ABSTRACT.
The objective of this study was to estimate the genetic?quantitative relationships between the beef fatty acid profile with the carcass and meat traits of Nellore cattle. A total of 1826 bulls finished in feedlot conditions and slaughtered at 24 months of age on average were used. The following carcass and meat traits were analysed: subcutaneous fat thickness (BF), shear force (SF) and total intramuscular fat (IMF). The fatty acid (FA) profile of the Longissimus thoracis samples was determined. Twenty-five FAs (18 individuals and seven groups of FAs) were selected due to their importance for human health. The animals were genotyped with the BovineHD BeadChip and, after quality control for single nucleotide polymorphisms (SNPs), only 470,007 SNPs from 1556 samples remained. The model included the random genetic additive direct effect, the fixed effect of the contemporary group and the animal?s slaughter age as a covariable. The (co)variances and genetic parameters were estimated using the REML method, considering an animal model (single-step GBLUP). A total of 25 multi-trait analyses, with four traits, were performed considering SF, BF and IMF plus each individual FA. The heritability estimates for individual saturated fatty acids (SFA) varied from 0.06 to 0.65, for monounsaturated fatty acids (MUFA) it varied from 0.02 to 0.14 and for polyunsaturated fatty acids (PUFA) it ranged from 0.05 to 0.68. The heritability estimates for Omega 3, Omega 6, SFA, MUFA and PUFA sum were low to moderate, varying from 0.09 to 0.20. The carcass and meat traits, SF (0.06) and IMF (0.07), had low heritability estimates, while BF (0.17) was moderate. The genetic correlation estimates between SFA sum, MUFA sum and PUFA sum with BF were 0.04, 0.64 and −0.41, respectively. The genetic correlation estimates between SFA sum, MUFA sum and PUFA sum with SF were 0.29, −0.06 and −0.04, respectively. The genetic correlation estimates between SFA sum, MUFA sum and PUFA sum with IMF were 0.24, 0.90 and −0.67, respectively. The selection to improve meat tenderness in Nellore cattle should not change the fatty acid composition in beef, so it is possible to improve this attribute without affecting the nutritional beef quality in zebu breeds. However, selection for increased deposition of subcutaneous fat thickness and especially the percentage of intramuscular fat should lead to changes in the fat composition, highlighting a genetic antagonism between meat nutritional value and acceptability by the consumer.

Abstract: Different nutritional management during the rearing and finishing periods can determine changes on beef fatty acid profile.
Beef lipid composition was quantified in 224 male Hereford calves weaned at 8 wk of age with an average initial live
weight (LW) of 170 ± 17 kg. After weaning, 4 nutritional treatments were imposed to obtain different daily LW gains (LWG;
kg/d) during the first winter. Nutritional management groups were high LWG in feedlot (HF), low LWG in feedlot (LF),
high LWG in pasture (HP), and low LWG in pasture (LP). The finishing phase began when each group reached a mean LW of
350 ± 28 kg. During the finishing phase, one-half of the HF, LF, HP and LP animals were finished on pasture and the other
half in a feedlot. The animals were slaughtered when calves in each treatment attained a mean LW of 500 kg. Analysis
of beef fatty acids was performed by extraction and methylation from LM, and the fatty acids were quantified using a gas
chromatography. The statistical model included the groups at growing phase (HF, LF, HP, and LP) and the groups at finishing
phase (feedlot or pasture) and the interaction between growing and finishing phase as fixed effects and LW at the
beginning of the finishing phase as a covariable. Tukey?s test was applied to compare the means (P < 0.05). There was interaction
between the growing and finishing phases for myristic acid and CLA cis 9, trans 11. Animals from HF finished on
pasture presented the highest concentration of myristic acid (2.54%) when compared with the other treatments. The LP
and HP groups finished on pasture had more CLA cis 9, trans 11 in their beef composition (0.60 and 0.58%, respectively),
whereas animals finished in the feedlot presented the lowest concentrations (average of 0.28%). Finishing phase affected
the fatty acid profile (P < 0.05). Higher concentrations of palmitic, oleic, and linoleic acids were observed in beef from
animals finished in the feedlot than in beef from those finished on pasture. However, the beef from animals finished on pasture
presented high concentrations of stearic, docosapentaenoic, and docosaexaenoic acids. Animals finished on pasture
had higher concentrations of linolenic, arachidonic, and eicosapentaenoic acids compared with those finished in feedlot. Interestingly,
the LP group presented higher concentrations of linolenic and eicosapentaenoic acids, regardless of the finishing
phase. The same results were observed in the LF group for arachidonic acid. In general, the LP and HP groups finished on
pasture resulted in healthy beefs, with the greatest CLA and omega-3 concentrations. MenosAbstract: Different nutritional management during the rearing and finishing periods can determine changes on beef fatty acid profile.
