“…Our rumination efficiency (RE) values are above what is in the literature because in this work the behavior was evaluated for 12 hours, while the works that evaluated these efficiencies did the behavior for 24 hours (Araújo et al, 2021;Silva et al, 2021). Thus, there is an increase in the RE values, due to the shorter times of rumination with emphasis on the fact that the animals ruminate with greater intensity at night (Kilgour, 2012).…”

This study evaluated the effect of increased energy via supplementation on the performance, ingestive behavior, nutrient digestibility, and nitrogen metabolism of grazing heifers fed tropical forage in the rainy-dry transition season. Treatments consisted of mineral supplementation ad libitum (control) and multiple supplements formulated to provide different energy levels and the same amount of protein (300 g CP animal d-1) and were denominated as low (LE; 340 g TDN animal d-1), medium (ME; 780 g TDN animal d-1) and high (HE; 1220 g TDN animal d-1) energy. Animals supplemented with ME, and HE had a greater average daily gain in relation to the control treatment, with an increase of 41 and 46%, respectively. Greater values for total apparent digestibility of neutral detergent fiber were observed for the treatment HE. Lesser values of urinary urea N were observed for the control and HE treatments. Our results define the use of energy levels in the supplement as a tool for pasture management. If the purpose of the production system is to enhance forage intake, the option is to supply supplements with less energy levels. In contrast, if the purpose is to increase the stocking rate, supplements with greater energy levels should be used.

“…The replacement of soybean meal with DCM did not influence the cattle's performance, possibly due to the adequate intake of protein and energy provided by the diets including DCM. Freitas et al (2017) and Araújo et al (2021) also did not observe an effect of including DCM in the supplement on the performance of meat sheep and grazing beef cattle, respectively. In the present study, average daily gain was higher than the 0.50 kg d -1 estimated in the formulation of the diets.…”

“…In this scenario, castor-bean (Ricinus communis L.) meal is a by-product with potential for use in ruminant diets after detoxification (Antunes et al, 2019). The detoxified castor-bean meal (DCM) presents 903 ± 13 g kg -1 DM; 320 ± 58 g kg -1 crude protein; 20 ± 2 g kg -1 ethereal extract; 383 ± 33 g kg -1 neutral detergent fiber; 62 ± 37 g kg -1 non-fibrous carbohydrates (Oliveira et al, 2019;Lima et al, 2020;Araújo et al, 2021). However, most research with DCM in ruminant feeding is conducted in feedlots (Diniz et al, 2011;Gionbelli et al, 2014;Novaes et al, 2020), and little is known about the effects of this ingredient on the production performance of grazing animals, especially beef cattle.…”

The use of agroindustrial byproducts in cattle diets, such as castor-bean (Ricinus communis L.) meal, is a more sustainable practice because it does not compete with human food and reduces the volume of organic waste deposited in the environment. The aim of this study was to examine the effect of replacing soybean (Glycine max (L.) Merr.) meal with castor-bean meal on the intake, digestibility, feeding behavior and performance of crossbred steers supplemented while on Urochloa brizantha (Hochst. ex A. Rich.) R.D. Webster 'Marandu' pasture. The experiment was laid out in a randomized complete design with 40 animals, which started the experiment weighing 227.1 kg, at 10 mo of age, and were divided into four treatment groups. Castor-bean meal was added to replace soybean meal at the levels of 0, 90, 180, and 280 g kg -1 in the supplement, which was supplied at the rate of 0.4% of body weight. Total DM, pasture DM and neutral detergent fiber intakes did not change (P > 0.05) with the castor-bean levels added to the supplement. Ether extract intake and digestibility decreased linearly (P < 0.05). The animals showed no differences (P > 0.05) in production performance (average daily gain), which averaged 0.65 kg d -1 . Grazing, idle, and rumination times were not influenced (P > 0.05) by the treatments. Castor-bean meal can be included up to 280 g kg -1 in the total diet without changing the performance of crossbred steers finished on tropical pasture.

“…In the case of by-products, the aim is to reduce supplement costs, as they replace costlier ingredients such as soybean (Matos et al 2018). For Araújo et al (2021), castor bean represents a good alternative in biodiesel production because it does not compete with other crops of importance in human nutrition. In addition, castor growing in Brazil is a promising activity.…”

This study examined different levels of replacement of soybean meal with detoxi ed castor bean meal in the nishing of crossbred steers on Brachiaria brizantha cv. Marandu pasture during the rainy-dry transition period. Forty Holstein-Zebu crossbred steers with an average initial weight of 395.93 ± 10 kg were randomly allocated to four treatment groups that were supplemented with concentrate containing different levels of castor bean meal replacing soybean meal (0, 30, 60, or 90%; at 0.4% body weight [BW]).The experimental period was 112 days. A completely randomized experimental design was adopted; with regression analysis conducted using the Statistical and Genetic Analysis System (SAEG). Intake and digestibility of dry matter (DM) and nutrients and animal performance were evaluated. The replacement of soybean meal with castor bean meal did not in uence (P>0.05) the intakes of DM (kg day -1 ), organic matter (OM, kg day -1 ), neutral detergent ber (NDF, kg day -1 and %BW), non-brous carbohydrates (NFC, kg day -1 ), or total digestible nutrients (kg day -1 ). However, the intakes of crude protein (CP) and ether extract (EE, kg day -1 ) decreased as the replacement levels were increased (P<0.05). The digestibility of DM, OM, NDF, and EE did not change, whereas CP digestibility decreased linearly and NFC digestibility increased linearly (P<0.05). The replacement levels did not affect (P>0.05) nal live weight, average daily gain, feed conversion, or carcass yield. Detoxi ed castor bean meal can replace up to 90% of soybean meal in the composition of the supplement without compromising the production performance of steers on Brachiaria brizantha cv. Marandu pasture during the rainy-dry transition period.
