Supplementation of grazing suckling beef calves receiving different energy sources
Lima, Josilaine Aparecida da Costa; Paulino, Mário Fonseca; Detmann, Edenio; Rennó, Luciana Navajas; Fernandes, Henrique Jorge; Silva, Aline Gomes daO objetivo deste trabalho foi avaliar o efeito de diferentes fontes energéticas, milho, sorgo e farelo de trigo, sobre o desempenho, o consumo, a digestibilidade aparente total dos constituintes da dieta e a eficiência de utilização dos compostos nitrogenados em bezerros de corte submetidos ao creep feeding. Foram utilizados 34 bezerros lactentes (12 machos e 22 fêmeas) com idade e peso médio inicial de quatro ...
Levels of multiple supplements or nitrogen salt for beef heifers in pasture dur...
Valente, Ériton Egidio Lisboa; Paulino, Mário Fonseca; Detmann, Edenio; Valadares Filho, Sebastião de Campos; Barros, Lívia Vieira deThe study assessed performance, microbial protein synthesis, intake and digestibility of nutrients by beef heifers receiving levels of multiple supplements or nitrogen salt, in a self-controlled intake, on pasture, during the dry season. Thirty-five beef heifers, from 6 to 9 months of age and average initial body weight of 203.4 + 4.5 kg, were used. Study factors were: control – mineral mixture; nitrogen salt –...

Rocha, Anilza Andréia da; Paulino, Mário Fonseca; Fernandes, Henrique Jorge; Barros, Lívia Vieira de; Lopes, Sidnei Antonio; Galon, LeandroThe objective of this study was to evaluate performance and nutritional traits of beef cattle raised on pastures, castrated at different ages, with and without supplementation. Forty-four crossbred young bulls with predominance of Zebu breed at initial average age of 120±30 days were used in the experiment. Animals were distributed in a completely randomized design in a factorial arrangement with four ages of c...
Net requirements of energy, protein and macrominerals for weight gain of grazin...
Rocha, Anilza Andréia da; Paulino, Mário Fonseca; Fernandes, Henrique Jorge; Barros, Lívia Vieira de; Lopes, Sidnei Antonio; Galon, LeandroThe objective of this experiment was to estimate the requirements of energy, protein and macrominerals of grazing crossbreds calves, in Brachiaria decumbens Stapf pasture, castrated at different ages, with and without supplementation. Forty-seven young calves at initial age of 120±30.1 days and 115.3±1.97 kg of live weight were used. To estimate net energy requirements for weight gain, a regression equation bet...

Barros, Lívia Vieira de; Paulino, Mário Fonseca; Valadares Filho, Sebastião de Campos; Detmann, Edenio; Silva, Felipe Gomes daObjetivou-se avaliar o efeito do uso de suplementos múltiplos com diferentes níveis de farelo de algodão 38% o sobre o consumo, a digestibilidade aparente total de componentes da dieta, a eficiência de síntese microbiana e o desempenho produtivo de novilhas de corte em pastagem de Brachiaria decumbens no período das águas. Utilizaram-se 25 novilhas nelores e 10 novilhas mestiças com predominância de sangue zebu...

Barros, Lívia Vieira de; Paulino, Mário Fonseca; Detmann, Edenio; Valadares Filho, Sebastião de Campos; Lopes, Sidnei Antonio; Rocha, Anilza Andréia daObjetivou-se avaliar o efeito de suplementos múltiplos com diferentes níveis de farelo de mamona (Ricinus communis L.) tratado com óxido de cálcio sobre o consumo, a digestibilidade aparente total de componentes da dieta, a eficiência de síntese microbiana e o desempenho produtivo de novilhas de corte em pastagem de Brachiaria decumbens durante o período de transição seca-águas. A área experimental foi composta...

Lopes, Sidnei Antonio; Paulino, Mário Fonseca; Detmann, Edenio; Valadares Filho, Sebastião de Campos; Barros, Lívia VieiraThe effects of supplementation with different levels of crude protein on performance, intake and nutrient digestibility and efficiency of microbial protein synthesis in suckling beef calves on pasture were assessed. Fifty-five calves, with an average age of 100 days and an initial average body weight of 110 ± 7.5 kg and their respective dams, were used. The experimental design was completely randomised with fiv...
