| The objective of this work was to evaluate the performance, body morphometric measurements and testicular development in lambs fed with different rates of sunflower meal inclusion. The animals (24) were randomly distributed in treatments with 0, 10, 20 and 30% of sunflower meal in the dry matter of the diet, in six replicates, during 56 days of confinement. The addition of the coproduct at increasing dietary rates increased linearly the dry matter intake in the percentage of live weight and neutral detergent fiber. Despite this, there was a linear reduction in ether extract intake and chest width. On the other hand, there was no difference in daily, total and final weight gains. The body condition score; height of withers, croup and thorax; length of body... |

| This study was carried out in order to assess commercial front and rear cuts of dairy-origin cattle fed mesquite pod meal. Twenty-five non-castrated male bovines (Holstein-Zebu), distributed according to a completely randomized design, with five animals per treatment, were used. The feed contained about 121.2 and 544.98 g kg-1 of crude protein and total digestible nutrients, respectively, and was composed of tifton grass hay, cornmeal, soybean meal, mesquite pod meal and mineral salt. The right half carcass of each animal was separated between the 5th and 6th ribs, in front and rear quarters, from which commercial cuts were obtained. There was no effect (p > 0.05) as to the replacement of corn for mesquite pod meal on the weights and yields of front... |

| ABSTRACT The objective of this study was to evaluate the effect of the partial replacement of elephant grass silage with babassu (Orbignya speciosa) on the performance, intake, digestibility, and carcass weight gain of sheep. Fifty-four castrated male lambs (19.08±2.76kg) were distributed in a completely randomized design and administered one of the following treatments: 0.0, 12.5, 25.0, 37.5 or 50% dry matter (%DM) replacement of elephant grass silage with babassu cake. No difference (P> 0.05) was observed in the dry matter, crude protein, and neutral detergent fiber intake, but the ether extract intake increased (P< 0.05). The digestibility of the dry matter, neutral detergent fiber, and total digestible nutrients were unaffected. The crude protein... |

| ABSTRACT: The objective in this trial was to determine the effects of partial replacement of ground corn by citrus pulp or soybean hulls on performance and carcass characteristics of feedlot goat kids. Twenty one Boer x Saanen kids (initial BW 15.8 ± 0.7kg), nine males and 12 females, were distributed in a complete randomized block design, according to sex and initial body weight. Treatments were set by replacing 50% of ground corn (DM basis) for citrus pulp or soybean hulls; whereas, forage concentrate ratio was of 10:90. Partial replacement of corn by citrus pulp or soybean hulls increased dry matter intake, average daily gain and final body weight, but feed efficiency was not affected. There was no difference between citrus pulp or soybean hulls.... |

| ABSTRACT: Additives are used in high concentrate diets to prevent metabolic disorders in cattle. This study was designed to evaluate the effect of calcium sources and monensin on the control of ruminal acidosis in Nellore cattle that were abruptly shifted to a high (92.3%) concentrate diet. Eight cannulated steers were randomly assigned to two contemporary 4x4 Latin square. Treatments involved the addition of a calcium source, either limestone (LI) or a product derived from calcareous algae (CA), to the basic diet with or without the presence of monensin. Calcareous alga (Lithothamnium calcareum) is a natural and renewable product and a source of calcium carbonate. The quantity of added limestone, calcareous algae and monensin was 7.1g kg-1, 7.4g kg-1 and... |

| ABSTRACT: The objective of this research was to examine the effect of subcutaneous fat thickness (SFT) on carcass characteristics and meat quality in 24-month-old British and crossbred British steers finished in feedlot systems. It was assessed using meta-analysis performed on data that was extracted from 46 published studies and comprising a total of 2,695 experimental units. We found that SFT was influenced by and increased linearly with hot carcass weights (HCWs) and cold carcass weights (CCWs) and their yields; moreover, the bone fraction decreased whereas the muscle and fat fractions increased with higher levels of SFT. No significant differences were detected in meat quality variables. Thus, SFT appeared to have a direct influence on HCW, CCW, and... |

| This experiment investigated the benefits of feeding steers bred from parents known to be of high genetic merit for feed efficiency (HE; midparent net feed intake-estimated breeding value (NFI-EBV) ≤-0.3kg/day), medium efficiency (ME: midparent NFI-EBV >-0.3 to 0.14 kg/day), or low efficiency (LE; midparent NFI-EBV ≥0.16kg/day). The steers were evaluated over a 251-day feeding period in a large commercial feedlot. Genetic superiority in NFI had a favourable impact on the commercial performance of Angus steers by reducing feed consumed with no adverse effect on final turnoff weight. Each HE steer consumed on average 2.60t of feed compared to 2.87t by the ME and LE steers, with no compromise in weight gain. The HE steers gained less subcutaneous ribfat... |
