Abstract

ABSTRACT. This research aimed to evaluate carcass traits of Zebu steers fed different oleaginous grains. Thirty one 23 months old zebu steers with 365 + 37.5 kg of live weight were used. The diets consisted ofcorn silage and four different concentrates; no additional lipids and three different ground oilseeds sources: soybean, cottonseed and linseed. The diets had concentrate:roughage ratio of 60:40 and were offered ad libitum. The experimental period was of 84 days, preceded by a 28 day adaptation period. The experiment was carried out in a randomized block design and the means were compared by Scott-Knott test at 5% level of probability. The CS inclusion of into the diet decreased (p < 0.05) carcass yield of the animals. The hindquarter was heavier (p < 0.05) with the addition of SB to the diet. The spare ribs had the highest performance (p < 0.05) and outside flat was heavier (p < 0.05) when the animals were submitted to CS and FS diets. The CS addition to the diet improved carcass characteristics.

Performance, carcass parameters, meat quality and lipid profile from feedlot young bulls fed cottonseed

“…For the hindquarter cut yield, difference with highest mean was found for cottonseed-supplemented animals and reduced values for weight forequarter (Table 2). On the other hand, Oliveira et al (2013) evaluating different fonts lipid in supplementation of feedlot cattle, verified difference from Thin flank with higher averages for animals supplemented with cottonseed, while for the other cuts (hindquarter and forequarter) was not found differences with control group. 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.…”

“…Diets were formulated meeting the requirements of 1.5kg daily weight gain according to the NRC (1996). The ingredients were furnished in the form of complete feed with isonitrogenous and isocaloric diets ( During slaughter the liver samples were collected and after cooling of the carcass for 24 hours at ± 1°C, the doing of the cuts and linear evaluations of the carcasses and determination of the parameters: Backfat thickness (BFT) and the rib-eye area was measured between the 12 th and 13 th ribs, Hot Carcass Weight (HCW), Hot Carcass Yield (HCY) according to live weight and yield of the cuts (Forequarter, Thin Flank and Hindquarter) is relative to cold carcass according to Oliveira et al (2013). The collecting of samples of the Longissimus thoracis muscle (Short loin) was done, their being packed in film paper (polyethylene), identified, placed into plastic bag from physicochemical analyses.…”
