“…The observed higher values of C18:0 in the meat of the animals that were fed 11.50% CS in the diet were closer to those reported by Costa et al (2013), who used 14.35% CS in the feed of the animals. Stearic acid, when consumed by humans, is absorbed in the intestines and transported to the liver by chylomicrons.…”

“…While Costa et al (2013) observed a linear decrease in EE of the muscle with the addition of CS to the diets of Nellore cattle, a positive correlation between the treatment was found in the present study on protected lipid and intramuscular fat. This finding shows greater efficiency of PL in the passage through the rumen towards the abomasum.…”

“…Whole cottonseed (CS) and calcium salts of fatty acids (CSFA) are options in cattle diets, once there are reports in the literature that a fraction of the fat in these ingredients goes through the rumen without being attacked by the microorganisms, is later on degraded and absorbed in the small intestines, producing meat of better quality (Huerta-Leidenz et al, 1991;Jenkins, 1993;Van Soest, 1994;Costa et al, 2013). Based on these facts, the objective of this study was to evaluate the centesimal composition, the fatty acid profile, and the sensory characteristics of M. longissimus thoracis of Nellore cattle fed diets containing lipid sources.…”

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.

“…This effect is undesirable because oleic acid intake contributes to increase plasma high-density lipoprotein (HDL) and decrease LDL and triglyceride concentrations in human blood (Gilmore et al, 2011). Costa et al (2013) observed a similar result for oleic acid concentration in meat as a function of different cottonseed levels in the diet (0%, 14%, 27% and 34%). In addition, greater NDF content in the cottonseed diets may have contributed to increase retention time of digesta in the rumen, where UFA were exposed to ruminal biohydrogenation for a longer time.…”

The objective of this study was to evaluate the fatty acid profile and qualitative characteristics of meat from feedlot young bulls fed ground soybean or ground cottonseed, with or without supplementation of vitamin E. A total of 40 Red Norte young bulls, with an initial average age of 20 months, and an initial average BW of 339 ± 15 kg, were allotted in a completely randomized design using a 2 × 2 factorial arrangement, with two oilseeds, and daily supplementation or not of 2500 IU of vitamin E. The experimental period was for 84 days, which was preceded by an adaptation period of 28 days. The treatments were ground soybean (SB), ground soybean plus vitamin E (SBE), ground cottonseed (CS) and ground cottonseed plus vitamin E (CSE). The percentage of cottonseed and soybean in the diets (dry matter basis) was 24% and 20%, respectively. Diets were isonitrogenous (13% CP) and presented similar amount of ether extract (6.5%). The animals were slaughtered at average live weight of 464 ± 15 kg, and samples were taken from the longissimus dorsi muscle for the measurement of fatty acid concentration and the evaluation of lipid oxidation and color of the beef. Before fatty acid extraction, muscle tissue and subcutaneous fat of the longissimus dorsi were separated to analyze fatty acid profile in both tissues. Supplementation of vitamin E did not affect fatty acid concentration, lipid oxidation and color (P > 0.05). Subcutaneous fat from animals fed CS diet had greater C12:0, C16:0 and C18:0 contents (P < 0.03). In addition, CS diets reduced the C18:1 and C18:2 cis-9, trans-11 contents in subcutaneous fat (P < 0.05). The muscle from animals fed CS tended to higher C16:0 and C18:0 contents (P < 0.11), and decreased C18:1, C18:2 cis-9, trans-11 and C18:3 contents (P < 0.05) compared with SB. The Δ 9 -desaturase index was greater in muscle from animals fed SB (P < 0.01). At 42 days of age, meat from cattle fed SB had a greater lipid oxidation rate (P < 0.05). Meat from animals fed SB diets had less lightness and redness indices than meat from animals fed CS diets after 14 days of age. In conclusion, the addition of ground cottonseed in the finishing diets did increase the saturated fatty acid content of the longissimus dorsi. However, animals fed cottonseed exhibited greater lightness and redness of beef. In this study, the addition of vitamin E did not affect qualitative characteristics of meat.

“…The high energy content of this oilseed can change ruminal fermentation by suppressing bacterial cellulolytic and methanogenic activity (Van Soest, 1994). Problems in beef flavor have been associated with the use of cottonseed (Costa et al, 2013). Given that cottonseed diets may compromise meat quality, it is critical to determine feed cottonseed and gossypol contents that will not change meat characteristics.…”
