Supplementation strategies for Nellore female calves in creep feeding to improv...
Almeida, Daniel Mageste de; Marcondes, Marcos Inácio; Rennó, Luciana Navajas; Martins, Leandro Soares; Marquez, David Esteban ContrerasThe objective of this study was to evaluate the effects of supplementation strategy on performance, nutritional and metabolic characteristics of Nellore suckling female calves, on grazing Urochloa decumbens during the rainy-dry transition period. Forty-four Nellore female calves, averaging 147.6 ± 1.34 kg (4 months), were used. A single supplement 20% of crude protein of dry matter was provided, consisting of d...
Nutritional planning for Nellore heifers post-weaning to conception at 15 month...
Almeida, Daniel Mageste de; Marcondes, Marcos Inácio; Rennó, Luciana Navajas; Silva, Luiz Henrique Pereira; Martins, Leandro SoaresThe objective of this study was to evaluate the effects of strategic supplementation in the dry period and dry/rainy transition period on the performance and nutritional, metabolic, and reproductive responses of Nellore heifers grazing Urochloa decumbens. Forty-eight Nellore heifers with age and body weight (BW) of eight months and 235 ± 3.3 kg, respectively, were used. The experimental design was a completely ...
Estimation of daily milk yield of Nellore cows grazing tropical pastures
Marcondes, Marcos Inácio; Rennó, Luciana Navajas; Barros, Lívia Vieira de; Cabral, Carla Heloísa Avelino; Martins, Leandro SoaresBeef cows’ milk yield is typically determined by measuring milk yield once daily and then doubling this value to estimate daily production. However, it is not known whether this is accurate. Thus, we aimed to determine the association between morning and afternoon milk yield in grazing Nellore cows. Eighty Nellore cows were used, with initial weight of 516.0 ± 1.0 kg. The experiment was a completely randomized ...
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 ...
