“…The daily excretion of creatinine and N-creatinine did not change significantly in this study, with average values of 27.3 mg/kg BW and 10.2 mg/dL, respectively. These values are consistent with those reported by Chizzotti et al (2006) and Lima et al (2013) who found no significant effect on creatinine excretion in cattle, which remained constant, despite the use of different diets.…”

“…The N balance was reduced with the inclusion of crambe, which was associated with urinary N excretion; a positive NB indicates protein retention in the animals, providing conditions that encourage weight gain in experimental animals. Lima et al (2013) also found a positive NB in animals supplemented with oil cakes, with significant faecal N excretion.…”

To evaluate the substitution of soybean meal by crushed crambe as a source of protein, five crossbred steers rumen cannulated weighting 426 ± 25 kg BW were distributed in a 5 Â 5 Latin square design. The steers were allocated in different levels of crushed crambe groups (0, 25, 50, 100 and 150 g/kg in concentrate supplement). Dry matter intake (DMI), rumen fluid pH, nitrogen (N) urinary excretion, propionate and isovalerate ruminal concentrations increased linearly (p < .05) with the replacement of soybean meal by crushed crambe. Crude protein (CP) intake, butyrate and valerate concentrations, and N retention and balance (g/d) showed linear decreases by the inclusion of crushed crambe. There was a quadratic decrease (p < .05) for neutral detergent fibre (NDF) intake and valerate concentration. Total short-chain fatty acids (SCFAs) increased quadratically (p < .05) with the inclusion of crushed crambe. The supplement and total DMI, digestibility of DM, CP and NDF, N-NH 3 , acetate, isobutyrate concentrations and intake, excretion faecal and total of N, microbial protein synthesis, urinary excretion and blood concentration of urea and creatinine were not affected (p > .05) by the crushed crambe inclusion in the diet. It is recommended that 100 g/kg of the crushed crambe inclusion replacing soybean meal supplements to grazing steers because improved supplement DMI and total SCFAs, reducing ruminal fermentation and nitrogen excretion, without affecting digestibility and microbial protein synthesis. HIGHLIGHTS DM intake and digestibility were not affected in steers fed crushed crambe. Urinary N excretion increased with crushed crambe replacing soybean meal.

“…However, decreases were observed when comparing N-NH 3 concentrations in 30 and 45% BNC diets during collection time, indicating that 30% BNC inclusion in the diet would provide, for a longer time, a greater ammonia availability for microbial protein synthesis. Nitrogen supply increases fiber digestion by improving microbial efficiency from substrate addition to ruminal flora (LIMA et al, 2013). Mesacasa et al (2015) observed lower N-NH 3 concentrations in the ruminal fluid by including sunflower cake in the diet, which is due to the highest coproduct indigestible fraction.…”

The inclusion effect of 0 (control), 15, 30, 45, 60, and 100% dry matter (DM) of Brazil nut (Bertholletia excelsa Bonpl.) cake (BNC) aiming at replacing corn silage was assessed on fermentation kinetics and effective degradability (ED) by means of in vitro gas production at 3, 6, 9, 12, 24, 48, 72 and 96 h. A randomized block design was used with six treatments, three blocks, and two replications per block. France's model was fit to the data. An in vivo experiment, conducted in fistulated ovine, assessed the effects of BNC inclusion levels of 0, 15, 30, and 45% DM replacing corn silage on ruminal parameters. Ruminal fluid samples were collected postprandial at 8, 10, 12, 14, 16, and 18 h for determining the concentrations of short-chain fatty acids (SCFA), pH, and N-NH 3 . A completely randomized design with repeated measures in time was used, with four treatments and three replications. Results of acetate, propionate, butyrate, acetate to propionate ratio, pH, and NH 3 were submitted to analysis of variance and regression (linear and quadratic) considering treatment, time and interaction of both. In addition, the F test with a 5% (P < 0.05) significance level was applied to the data. Fermentation kinetics pattern and ED presented a linear decreasing (P < 0.05), which means a decrease in total gas production at each coproduct inclusion level. No interaction effect between treatment and time was observed for total SCFA (P > 0.40), acetic acid (P > 0.41), propionic acid (P > 0.85), butyric acid (P > 0.62) and pH (P > 0.57). BNC replacements of 0, 15, 30 and 45% did not change (P > 0.05) total SCFA concentration, as well as acetic acid concentration in ovine. When including 45% DM of BNC, concentrations (mMol/100 mL) of propionic (P < 0.001) and butyric (P < 0.022) acids was reduced in the ruminal fluid. The highest concentrations at measurement times were observed 4 hours after feeding. The pH values presented a quadratic effect on both inclusion (P < 0.001) and time (P < 0.001). An interaction was observed between treatment and time for N-NH 3 concentration (mg/ml) (P < 0.001) and acetic to propionic acids ratio (P < 0.014). Fermentation kinetics was negatively affected by Brazil nut cake inclusion to corn silage-based diet. Therefore, the use of this coproduct is recommended associated with non-structural carbohydrate sources. ResumoAvaliou-se o efeito da inclusão da torta da amêndoa de castanha-do-pará (Bertholletia excelsa Bonpl.) -(TAC) nas proporções 0 (controle), 15, 30, 45, 60 e 100% da matéria seca (MS) em substituição à silagem de milho (SM), sobre a cinética de fermentação e a degradabilidade efetiva (DE), através da produção de gases in vitro, nos tempos 3, 6, 9, 12, 24, 48, 72 e 96 horas. Utilizou-se delineamento em blocos casualizado, com seis tratamentos, três blocos e duas repetições por bloco. O modelo de France foi ajustado aos dados. Ensaio in vivo, conduzido em ovinos fistulados, avaliou-se a influência da TAC nos níveis 0, 15, 30 e 45% (MS), em substituição à silagem de milho, sobre ...
