“…Greater concentration of PUFA (10.40%) that was observed in the ingredient (CSFA) by Silva et al (2009), compared with the reduced value (2.96%) of these acids in the PL (ingredient) of the present study, certainly collaborated with increased PUFA levels observed in the meat and caused by greater ingestion of PUFA by the cattle, leading to increased flow of unsaturated fat into the duodenum. Similar study by Andrade (2014) who fed 60% concentrate in a corn-based diet to confined animals diets containing PL or not, observed reduced PUFA contents in the meat when PL was included in the feed. The quantity of corn-based concentrate may have collaborated for a more acid rumen environment, leading to the dissociation of the protected lipid in the rumen and, consequently, to the saturation of part of the PUFA.…”

“…Several authors (Andrade, 2014;Fiorentini et al 2012;Souza et al 2007) observed that the lipid sources in the diet did not change most of the FA in cattle meat. According to Patil et al (1993), when ruminants are fed high concentrations of fat, either partially or completely protected from the microbial action of the rumen, there may be an increase in percent intramuscular fat and changes in the fatty acid profile.…”

The objective of this study was to determine the effect of the dietary inclusion of lipid-based diets (whole cottonseed and protected fat) on the centesimal composition, fatty acid profile, and sensory properties of meat from finishing Nellore cattle. The study was carried out from August to October 2009. Thirty nine uncastrated Nellore males with average initial body weight of 494.1 ± 10.1 kg and 36 months of age were housed for 63 days in pens with thirteen animals each. A completely randomized design with three treatments and thirteen replications was used. The treatments evaluated were: feed with 2.50% cottonseed (control diet); feed with 11.50 % cottonseed; and feed with 3.13% cottonseed added of protected lipid (PL), all on a dry matter basis. No differences between treatments were observed for moisture, protein, and ash contents. However, the addition of protected fat caused an increase in the percentage of ether extract in the meat. Diets containing cottonseed or protected lipid did not affect fatty acid concentration in the meat. The intensity of the aroma, strange aroma, flavor, strange flavor, juiciness, color, and overall appearance were similar between treatments, except for tenderness, which was positively affected in cattle fed a diet in which the only lipid source was cottonseed. The study demonstrated that the addition of PL in the diets of finishing cattle led to greater levels of intramuscular fat, but to less tender meat than the other treatments.

“…However, palmitic (C16:0), stearic (C18:0) and oleic (C18:1 cis-9) fatty acids, that account for more than 70% of all beef lipid composition, presented high degree of consistency among those results. Major variations were observed for linoleic (LA; C18:2 cis-9,12) and arachidonic acids (AA; C20:4 cis-5,8,11,14) concentrations compared to those presented by Andrade et al (2014), Padre et al (2006) and Fredriksson, Eriksson and Pickova (2007). Although these fatty acids showed higher amounts than observed by previous authors, Brugiapaglia et al (2014) showed similar results compared to those found by these authors and higher concentrations than reported by San Vito et al (2015) and Andrade et al (2014).…”

“…Identified fatty acids (Table 1) shows high variability concentration among those previously reported for Nellore breed or crossbreed animals (ANDRADE et al, 2014;GAMA et al, 2013;PADRE et al, 2006;SAN VITO et al, 2015). However, palmitic (C16:0), stearic (C18:0) and oleic (C18:1 cis-9) fatty acids, that account for more than 70% of all beef lipid composition, presented high degree of consistency among those results.…”

“…However, beef meat has the challenge to become more competitive in relation to meats from other species like poultry and swine, which have their primal cuts standardized. To achieve this goal, the industry should invest in qualitative aspects, producing high-quality carcasses and meat in an attempt to captivate the Brazilian consumer and broaden its competition in the external market, which has been the ultimate lever for the incentive and growth of this activity (Andrade, Polizel, Roça, Faria, Resende, Siqueira & Pinheiro, 2014). In this regard, primal cuts deserve the attention of slaughterhouses, since both the internal and the external markets require minimum weights of certain muscles that make up these cuts.…”

The aim of this study was to evaluate the boneless yield of the carcass of 64 feedlot-finished young Nellore bulls fed diets containing coated or uncoated urea and slaughtered at five body weights (350, 455, 485, 555, and 580 kg). A completely randomized design with a 5 × 2 factorial arrangement was used. No significant effect was detected for the interaction between slaughter weight and diet; therefore, the variables were analyzed separately, compared by polynomial contrasts and the F test, respectively. The absolute weights of the primal cuts from the fore-and hind-quarter increased linearly as the slaughter weight of the animals increased. Increasing slaughter weights elevated the percentage of rump cap in the pistola hindquarter as well as its yield. The percentages of the rump cap and rump skirt increased linearly, whereas those of knuckle, tenderloin, flank steak, rump, and outside flat decreased and the sum of prime cuts had a quadratic effect in relation to the weight of the right 1/2 carcass. Increasing slaughter weights led to a higher percentage of fat from the trimming of the hindquarter cuts relative to the weight of the 1/2 carcass. The weight of meat cuts was similar between the groups of animals fed coated and uncoated urea. Higher slaughter weights generate heavier meat cuts but lower percentages of primal cuts from the pistola hindquarter relative to the carcass weight.Key words: Animal products; cattle; meat; prime cuts; Nellore breed; diet; minimum weight; optigen®. ResumenEl objetivo de este estudio fue evaluar el rendimiento deshuesado en canal de 64 toros jóvenes Nellore alimentados en corral con dietas que contienen urea recubierta o sin recubrir y sacrificados a cinco pesos corporales (350, 455, 485, 555 y 580 kg). Se utilizó un diseño completamente aleatorizado con un arreglo factorial de 5 × 2. No se detectó ningún efecto significativo para la interacción entre el peso de sacrificio y la dieta; por lo tanto, las variables se analizaron por separado, en comparación con los contrastes polinómicos y la prueba F, respectivamente. Los pesos absolutos de los cortes primarios del cuarto anterior y posterior aumentaron linealmente a medida que aumentaba el peso del sacrificio de los animales. El aumento de los pesos de sacrificio elevó el porcentaje de la tapa de la grupa en el cuarto trasero de la pistola, así como su rendimiento. Los porcentajes de la gorguera y la falda de la rabadilla aumentaron linealmente, mientras que los de nudillo, lomo, filete de flanco, grupa y plano exterior disminuyeron y la suma de los cortes primarios tuvo un efecto cuadrático en relación con el peso de la mitad de la carcasa. El aumento de los pesos de matanza condujo a un mayor porcentaje de grasa del recorte de los cortes del cuarto trasero en relación con el peso de la carcasa 1/2. El peso de los cortes de carne fue similar entre los grupos de animales alimentados con urea recubierta y no recubierta. Los pesos de sacrificio más altos generan cortes de carne más pesados pero porcentajes más bajos de ...
