Última Simulation and validation of the ruminal digestion of carbohydrates in cattle from kinetic parameters obtained by in vitro gas production technique R. Bras. Zootec. Silva Cabral,Luciano da; Campos Valadares Filho,Sebastião de; Detmann,Edenio; Zervoudakis,Joanis Tilemahos; Galati,Rosemary Lais; Paula Sousa,Daniel de; Souza,Alexandre Lima de. This study aimed to validate the estimates of the ruminal degradation of total carbohydrates (TC), ruminal and total digestion of fibrous carbohydrates (FC) and microbial nitrogen flow in the abomasum evaluated by in vitro gas production technique (IVGP). Six ruminally and abomasally cannulated steers arranged in a double 3 × 3 latin square were used to measure described parameters with indigestible neutral detergent fiber (INDF) utilization as marker. Total and fibrous carbohydrates degraded in the rumen were estimated through digestion rates obtained for fibrous (FC) and non fibrous carbohydrates (NFC) using in vitro gas production technique, corrected for its respective ruminal and postruminal passage rates. The estimation of the total digestion of FC... Tipo: Info:eu-repo/semantics/article Palavras-chave: Degradation; Fiber; Flow; Microbial nitrogen; Passage rate.

Bras. Zootec. Valente,Ériton Egidio Lisboa; Paulino,Mário Fonseca; Detmann,Edenio; Campos Valadares Filho,Sebastião de; Barros,Lívia Vieira de; Acedo,Tiago Sabella; Couto,Victor Rezende Moreira; Lopes,Sidnei Antonio. The 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 - 50% of urea + mineral mixture, at proportion of 1:1, and 50% of corn (75% of crude protein); levels of multiple supplementation - multiple supplements with different percentages of intake controller mixture (urea + mineral mixture, at the proportion of 1:1), corn and soybean meal (45% of crude protein). Supplement consumptions observed were: 115,... Tipo: Info:eu-repo/semantics/article Palavras-chave: Digestibility; Intake; Performance; Self-control.
