“…Contrary to the previous studies, Costa et al (2011) found a linear decrease in DM intake of cattle as levels of cottonseed were increased, and justified this reduction as an effect of the reduction in fiber digestibility and the increase in rumen retention time of ingestion caused by greater amount of EE in the diet. Interestingly, the same authors found that this effect occurred in diets with levels of EE above 5%, and, in this experiment, 5% was the maximum threshold used.…”

“…However, differences in dry matter (DM) intake related to fat sources using cottonseed and its by-products were also observed (Cranston et al, 2006). Furthermore Costa et al (2011) found a linear decrease in DM intake and weight gain of cattle with increase of cottonseed levels; or Gunn, Weaver, Lemenager, Gerrard, Claeys, and Lake (2009), who found a reduction in gain of Angus cattle fed with distillery waste and soybean oil.…”

In feedlot system is particularly important to reduce the cattle feeding cost without impact on the animal gain and carcass, in this sense, aimed with this study to evaluate animal performance and carcass traits of the young Nellore male (n = 40) finished with agro-industrial by-products in feedlot diet. The addition of cottonseed by-product (CSB) was based on the ether extract (EE) contents in the feedlot diet: 3, 4 and 5%; and two other reference treatments were also tested, with 3 and 5% of EE content and soybean by-product (SOB) as fat source, totalling five experimental diets. In diets with 3% EE, CSB did not alter performance, gain cost or carcass traits compared to the SOB. In diets with 5% EE, animals fed with CSB showed greater dry matter (DM) intake than animals fed with SOB (10.34 versus 8.94 kg/day), but because CSB is a cheaper ingredient than SOB, it reduced the gain cost from 1.60 to 1.35 US$/kg. The CBS used in diet with 3, 4 and 5% EE increased the daily gain (1.17, 1.38 and 1.50 kg/day) and the rumination time (225, 338 and 370 min/day, respectively). So, CSB does not change the carcass traits nor the feeding behaviour when compared to SOB. The increased of CSB concentration in the diet raised the daily gain, DM intake and rumination time, with no changes in carcass traits.

“…However there were no significant differences among the treatments for the exit weight of the animals, rib-eye area, BFT and carcass weight. Costa et al (2011) found similar results for the rib-eye area values according to different cottonseed levels in the diet. While for daily weight gain, carcass final weight and fat thickness these authors found a linear decrease effect with increasing levels of cottonseed up to 34.09%.…”

“…Cranston et al (2006) in including 15.1% of cottonseed in the diet of beef steers obtained results similar to that of this present study for the Rib-eye area and BFT, however, these authors found no differences for DWG and HCY on the contrary of the results obtained in this work. Costa et al (2011) with increased addition of cottonseed into the diet of cattle, found reduction of the carcass weight and coverage Backfat thickness. The final pH values (24h) are within the normal range expected for beef; however, there was significant reduction for meats obtained from the cottonseed-treated group (Table 2).…”

SUMMARY The objective of this study was to evaluate the performance, carcass, meat quality, fatty acid profile and liver alterations of cattle supplemented with cottonseed feedlot. It used 100 Nelore cattle, being divided into two groups of 50 animals, which received a cottonseed (CS) in grain form by the diet in the proportion of 15% and the other group was provided with control diet without CS in the feedlot for 88 days. The diets were isoprotein and isoenergetic and concentrate:roughage ratio of 60:40. The animals were slaughter in the end of experimental time and the collection of liver samples for histological analysis. After cooling 24 hours at ± 1°C were conducted evaluation of carcass and major cuts, final pH and collected muscle samples longissimus to carry out the physicochemical analyzes (Color, Cooking Loss, Pigments and Shear Force), chemical composition, fatty acid profile and oxidation. The inclusion of CS in the diet provided animals with higher slaughter weight, daily weight gain, Hindquarter, however, the animals showed reduced carcass yield, forequarter weight and Thin flank, without changing the parameters as rib-eye area and backfat thickness. There was an increase of the yellow values (b*) and moisture with the final pH reduction. There was no influence of the use of cottonseed in relation to histological parameters evaluated in the liver. The cottonseed in the feeding feedlot cattle promoted improvement in animal performance, despite the reduction of the forequarter weight, with appropriate aspects of meat quality, fatty acid profile and conservation.

“…Likewise, no effect on diets was observed on the variable cold carcass weight (P>0.05). Costa et al (2011) also did not observe effect of different levels of cottonseed (0, 14, 27 and 34% DM) in the diet on the hot carcass weight. However, HuertaLeidenz et al (1991), in an experiment with crossbred Hereford-Angus cattle finished for a period of 56 days and subjected to diets with cottonseed at levels 0, 15 and 30% dietary DM observed significant decrease in the weight of carcass and also rib-eye area at the level of 30% inclusion of cottonseed.…”

-The objective of this research was to evaluate average daily gain (ADG), carcass traits, meat tenderness and profitability of keeping cattle fed different oilseeds and vitamin E in feedlot. A total of 40 Red Norte young bulls with initial average body weight of 339±15 kg were utilized. The experimental design was completely randomized in a 2 × 2 factorial arrangement. The experiment lasted 84 days and experimental diets presented soybeans or cottonseeds as lipid sources associated or not to daily supplementation of 2,500 UI vitamin E per animal. The concentrate:roughage ratio was 60:40. Diets had the same amount of nitrogen (13% CP) and ether extract (6.5%). The data were analyzed by means of statistical software SAS 9.1. Neither vitamin supplementation nor lipid source affected ADG. There was no interaction between lipid source and vitamin supplementation for the variables studied. The inclusion of cottonseed reduced the carcass yield. There was no effect of diets on hot and cold carcass weights or prime cuts. The inclusion of cottonseed reduced the backfat thickness. No effect of experimental diets on the rib-eye area was observed. There was no effect of lipid source or vitamin supplementation on meat tenderness, which was affected, however, by ageing time. Diets with soybeans presented higher cost per animal. The utilization of soybean implied reduction of the gross margin (R$ 59.17 and R$ 60.51 for diets based on soy with and without supplemental vitamin, respectively, vs. R$ 176.42 and R$ 131.79 for diets based on cottonseed). The utilization of cottonseed enables improvement of profitability of feedlot fattening, in spite of negatively affecting some carcass characteristics.
