Chemical and Fatty acid composition of different cuts cooked or uncooked from yearling bulls fed oil sources Animal Sciences
Oliveira, Emanuel Almeida de; Sampaio, Alexandre Amstalden Moraes; Henrique, Wignez; Pivaro, Thiago Martins; Rosa, Bruna Laurindo; Fernandes, Alexandre Rodrigo Mendes.
This study evaluated the chemical and lipid composition of uncooked or cooked loin (Longissimus thoracis) and rump (Biceps femoris) in samples of 2.54 cm thick from 35 carcasses of Nellore young bulls finished in feedlot for 96 days and slaughtered at an average weight of 532.17 ± 30.25 kg and 24 months of age. The rump had the lowest level of protein and ash (18.57 and 0.90%, respectively) and the highest level of ether extract compared to loin (3.37 and 1.90%, respectively). Higher levels of cholesterol were found in rump compared to loin (40.91 e 30.93 mg 100 g-1, respectively). The uncooked loin showed lower content of saturated fatty acids and higher content of polyunsaturated fatty acids. The best values for the omega-6: omega-3 ratio was observed in...

Performance and digestibility in feedlot lambs fed hay based diets Animal Sciences
Oliveira, Euclides Reuter de; Monção, Flávio Pinto; Gabriel, Andréa Maria de Araújo; Fernandes, Alexandre Rodrigo Mendes; Moura, Lais Valenzuela; Nascimento, Felipe de Almeida.
This study aimed to evaluate the performance of feedlot lambs fed diets formulated with hay of different genotypes of Cynodon spp. and to compare the dry matter digestibility of diets using different evaluation methods (total fecal collection and chromium oxide). Suffolk crossbred neutered male lambs (n=30), with an average age of 90 days and average body weight of 21.5 kg ± 1.6. Diets were formulated using a standard concentrate and hay of the following genotypes of Cynodon dactylon: Jiggs, Vaquero, Tifton 68, Coast-Cross, Tifton 85 and Russell, in a 60:40 forage concentrate ratio, composing the treatments distributed in a randomized block design in a factorial 5 x 2 arrangement of 5 diets and 2 digestibility evaluation methods. Animals receiving Vaquero...
