Bayão,Geraldo Fábio Viana; Marcondes,Marcos Inácio; Queiroz,Augusto César de; Pimentel,Robérson Machado; Cardoso,Lucas LadeiraABSTRACT The objective of this study was to evaluate the chemical composition and the fermentative parameters of heart of palm waste produced from Alexander Palm, ensiled with chemical additives. Treatments consisted of silage of the sheath with or without calcium oxide. In the silage without calcium oxide, we evaluated the control silage (without additive) and the silage enriched with 5.0 g kg−1 urea (urea). I...
Carcass characteristics of feedlot-finished Zebu and Caracu cattle
Resende,Flávio Dutra de; Gesualdi Júnior,Antonio; Queiroz,Augusto César de; Faria,Marcelo Henrique de; Viana,Alexandre PioThis study analyzes the chemical carcass characteristics and carcass losses in 86 cattle, both castrated and non-castrated, with an average initial weight of 329 kg and an average age of approximately 20 months, including 12 Gyr, 20 Guzerat, 20 Nellore, and 20 Caracu among the herds selected for weight determination at 378 days of age, as well as 14 Nellore cattle that were not selected. The diet contained a ro...
Effect of whey fermented by Enterococcus faeciumin consortium with Veilonella p...
Bezerra,Higor Fábio Carvalho; Oliveira,Juliana Silva de; Santos,Edson Mauro; Queiroz,Augusto César de; Mantovani,Hilário CuquettoThe objective of this research was to evaluate the effect of whey fermented by Enterococus faecium in consortium with Veilonella parvula in vitro on ruminal microorganisms in different substrates, with or without monensin. The first experiment was carried out in a completely randomized design, in a 6 × 3 factorial arrangement (six substrates × three whey levels) with two replicates. In experiment two, a 2 × 3 ×...
Economic viability of the use of crude glycerin supplements in diets for grazin...
Almeida,Vitor Visintin Silva de; Silva,Robério Rodrigues; Queiroz,Augusto César de; Oliveira,Aline Cardoso; Silva,Fabiano Ferreira daThe objective of this study was to evaluate the economic returns of crossbred calves grazing on pastures formed by Urochloa brizantha fed crude glycerin as a supplement. Thirty-six crossbred calves with initial average weight of 301.5 kg were distributed in a completely randomized design with four treatments and nine replicates per treatment. The animals were maintained on rotational grazing production of Uroch...
Evaluation of whey fermented by Enterococcus faecium in consortium with Veilone...
Oliveira,Juliana Silva de; Queiroz,Augusto César de; Mantovani,Hilário Cuquetto; Bayão,Geraldo Fábio Viana; Detmann,Edenio; Santos,Edson MauroThe objective of this study was to evaluate the whey fermented by Enterococcus faecium in consortium with Veilonella parvula on the in vitro growth of ruminal bacteria and as a supplement in the cattle diet. In the in vitro experiment, a randomized design, with the following combinations was used: ruminal bacteria; ruminal bacteria and inactive whey; ruminal bacteria and active whey; and active whey. In the in ...
Evaluation of sodium sulfite and protein correction in analyses of fibrous comp...
Gomes,Daiany Íris; Detmann,Edenio; Valadares Filho,Sebastião de Campos; Mezzomo,Rafael; Souza,Natália Krish de Paiva; Queiroz,Augusto César deThe objective of this study was to evaluate the contents of fibrous compounds in tropical grasses and legumes according to utilization of sodium sulfite in the neutral detergent solution or using a procedure for contaminant protein correction. Samples of ten grasses and ten legumes were used. The contents of neutral detergent fiber were decreased when sodium sulfite was used; however, more prominent reductions ...
Perfil metabólico e desenvolvimento da glândula mamária de novilhas leiteiras s...
Costa,Patrícia Barcellos; Queiroz,Augusto César de; Rodrigues,Marcelo Teixeira; Magalhães,André Luiz Rodrigues; Zorzi,Karina; Mello,ReniusObjetivou-se avaliar o efeito do manejo para crescimento compensatório e da suplementação com ionóforo sobre o perfil metabólico e o crescimento da glândula mamária de novilhas leiteiras. Foram utilizadas 20 novilhas Pardo-Suíças puras, com peso inicial de 200 kg e 5 meses de idade. Os tratamentos foram arranjados em esquema fatorial 2 × 2 e os animais foram alocados aleatoriamente em cada uma das combinações. ...
Chemical composition and ruminal degradation kinetics of crude protein and amin...
Miranda,Lidia Ferreira; Rodriguez,Norberto Mario; Pereira,Elzânia Sales; Queiroz,Augusto César de; Sainz,Roberto Daniel; Pimentel,Patrícia GuimarãesThe objective of this research was to determine the chemical composition and ruminal degradation of the crude protein (CP), total and individual amino acids of leaves from tropical forages: perennial soybean (Neonotonia wightii), cassava (Manihot esculenta), leucaena (Leucaena leucocephala) and ramie (Boehmeria nivea), and to estimate the intestinal digestibility of the rumen undegradable protein (RUDP) and ind...
Evaluation of models for prediction of the energy value of diets for growing ca...
Sampaio,Cláudia Batista; Detmann,Edenio; Valadares Filho,Sebastião de Campos; Queiroz,Augusto César de; Valente,Tiago Neves PereiraThe objective of this study was to estimate and evaluate the contents of apparently digestible fractions of crude protein, ether extract and non-fibrous carbohydrates, the digestible fraction of the neutral detergent fiber and the content of total digestible nutrients (TDN) from the chemical composition of feeds in growing cattle fed different diets. Fourteen F1 Red Angus × Nellore young bulls with average age ...
Desempenho produtivo de vacas recebendo dietas com capim-elefante submetido a d...
Oliveira,Tadeu Silva de; Pereira,José Carlos; Queiroz,Augusto César de; Cecon,Paulo Roberto; Santos,Márcia Vitória dosOs objetivos deste trabalho foram determinar o consumo de matéria seca total (MSDT), a produção e composição do leite de vacas lactantes quando submetidas a dietas à base de capim-elefante adubado quimicamente (CEAQ) ou organicamente (CEAO) e a energia líquida para lactação (ELL) e os nutrientes digestíveis totais (NDT) do capim-elefante na dieta. O CEAQ ou CEAO foi misturado ao concentrado em níveis de 400, 50...
