“…Esto demuestra que no hubo deficiencia de compuestos nitrogenados para el crecimiento de microorganismos fibrolíticos, lo que puede explicar la digestibilidad de FDNcp similar entre los tratamientos (Tabla 4). Resultados similares fueron reportados por otros autores al suplementar bovinos en condiciones tropicales con diferentes tipos y cantidades de suplementos (9,22,23,24).…”

“…Además, debido al elevado costo de las principales fuentes de proteínas utilizadas en la formulación de suplementos para ganado, como la torta de soya (TS), el uso de fuentes proteicas alternativas puede optimizar los resultados, ya sea mediante la reducción de los costos de producción sin comprometer el desempeño, o mediante una mejor adecuación de los nutrientes disponibles para satisfacer las necesidades metabólicas de los animales (5). Por consiguiente, los investigadores han tenido un interés creciente en el uso de otras fuentes de alimentos, como la torta de semillas de algodón, la torta de ricino, el salvado de trigo más urea y la urea en la dieta de bovinos (6,7,8,9).…”

Objective. Evaluate the effects of supplementation with different protein sources (soybean meal and wheat bran with urea) on the productive performance, intake, digestibility, microbial protein synthesis, and metabolic profile of grazing beef heifers. Materials and methods. Were used twenty Nellore heifers at 8.5±0.06 months of age, with an initial average body weight of 241.5±4.71 kg. The animals were distributed in a completely randomized deseing with two treatments and ten replicates. Two protein sources in the supplements were evaluated: 1) Soybean meal (SBM), and 2) Soybean meal + Wheat bran + Urea (SBM+WB+U). Results. Crude protein (CP) and organic matter intakes were higher (p<0.05) for heifers from SBM compared with SBM+WB+U. The CP digestibility was increased (p<0.05) with SBM supplementation. Mean blood concentrations of glucose, cholesterol, serum urea nitrogen, and total proteins were not affected (p>0.10) by protein sources. In the same way, daily weight gain and final body weight were not influenced (p>0.10) by protein sources. Conclusions. The supplementation with soybean meal or wheat bran with urea in association with soybean meal in multiple supplements for grazing cattle provides similar productive and nutritional performance and metabolic profile in beef heifers.

The purpose of this study was to determine the effect of cow’s grazing supplementation during pregnancy on the concentration of metabolites in blood and its relation with uterine involution and postpartum fertility. Twenty-seven Nellore cows were divided into three groups (n=9 for each group) as follows: UNS, unsupplemented during gestation; MID, supplemented from the 30 to 180-day of gestation; LATE, supplemented from the 181 to 281-day of gestation. Blood samples to determine the concentrations of NEFA, BHBA (β-hydroxybutyrate) and the glucose was performed on days 30, 105, 180, 230 and 281 of gestation. Fixed-time artificial insemination (FTAI) was performed in all matrices at forty-five days postpartum. Lower NEFA and BHBA concentrations it was observed in the MID and LATE group at 180 and 281 days of gestation respectively for each treatment. A higher glucose concentration was observed at 180 and 281 days of gestation for MID and LATE treatment, respectively. There were no differences in uterine involution and percentage of gestation between treatments. Pre-partum supplementation improves energy balance without altering uterine involution and postpartum fertility.
