“…However, the best of the three treatments was PM20 because of its higher values in both sales of live and slaughtered animals. Thus, in concordance with the study of Barros et al (2015), we observed the benefits of using biodiesel co-products in animal feed. However, prior to recommending the use of these new ingredients, a key point is to ensure standardization of these products sold by the agroindustry.…”

The aim of this study was to evaluate the animal performance, commercial cuts, and their yields within the production system, and economics of sheep production, of lambs finished in feedlots and fed with or without biodiesel co-products. A total of 40 lambs were divided into four biodiesel co-product treatment groups: a no-treatment control; peanut meal; crude glycerin; and peanut meal + crude glycerin. Animal performance did not differ (P > 0.05) among the treatment groups, where the average daily gain was close to 0.26 kg/day. Likewise, the quantitative carcass characteristics did not differ (P > 0.05) and the biological mean yield was 54.92%. Similarly, the commercial cuts and their yields did not differ (P ≥ 0.09) among the treatments. These results took into consideration the standard, age, and slaughter body weight of the animals. The economic evaluation determined that peanut meal was the best co-product for use in finishing lambs in a feedlot. Hence, all the biodiesel co-products evaluated can be used at feedlots to finish lambs without changing the variables measured.

“…The observed behaviour for the EBW, HCW, and CCW variables may be related to DM intake and ME intake due the fact that glycerol from CG may have increased dietary energy efficiency by the microorganisms in the rumen and consequently favoured the synthesis of tissues in the body of the animal. The BWS values are between the intervals of studies on sheep of the same age that were fed CG in confinement and were slaughtered when they were between 25 and 38 kg [7,8,19,20]. In the present study the animals were slaughtered at an average of 35.21 kg and presented a linear behaviour that increased with the inclusion of CG in the diets, with a better performance of the animals as the amount of corn replaced by CG increased.…”

“…The goal is to obtain higher weights at younger ages to meet consumer market demands [6]. Some studies have evaluated the effects of CG on the diets of sheep and cattle by substituting concentrated feeds and/or associated with urea [7–9], and improvements were achieved or these changes did not impair weight gain and carcass characteristics.…”

ObjectiveAn experiment was conducted to evaluate the effects of increasing levels of crude glycerin (0%, 6%, 12%, and 18%) used as a substitute for corn in lamb feed on the quantitative characteristics of the carcass.MethodsA total of 40 crossbred Santa Inês lambs that were four months old with a mean initial weight of 21.0±0.8 kg were randomly distributed in four treatments with ten replicates. The animals were slaughtered after 66 days of confinement. The effects of crude glycerin as a replacement for corn in the diet of the lambs on the carcass characteristics, commercial cut weight and yield and carcass measurements were studied.ResultsThere was an increasing linear effect for body weight at slaughter with the replacement of corn by crude glycerin. The dry matter and metabolizable energy intakes, weight of the empty body, hot carcass weight and cold carcass weight showed a quadratic effect, with maximum crude glycerin levels estimated at 10.9%, 9.8%, 10.83%, 11.78%, and 11.35%, respectively. The initial pH was not influenced by the replacement of corn for crude glycerin, while the final pH presented a quadratic effect. The other parameters of the carcass and the weights and yields of commercial cuts were not influenced. There was also no effect of the diets on carcass morphometric measurements, except for the thoracic perimeter and the carcass compactness index, which presented quadratic and linear effects, respectively.ConclusionCrude glycerin can replace up to 18% of corn because it favours muscle tissue deposition without promoting changes in the main carcass characteristics of lambs.

“…Agreeing with this study, Gomes et al (2011) found no differences in DMI, feed conversion, daily weight gain, and final body weight with the inclusion of crude glycerin (300 g kg −1 of diet DM) to the diet for lambs. Lage et al (2010), Avila-Stagno et al (2013), and Barros et al (2015) indicated the use of smaller proportions of crude glycerin than that used in the present experiment due to decreased DMI. The administration of the feed in this experiment, crude glycerin conveyed to water, may have determined maintenance of DMI and performance, since there is a slower intake of glucose and propionate, an important hypothalamic informant of the degree of satiety (Allen, 2000).…”

Performance and carcass characteristics of lambs fed a solution of crude glycerin during feedlot and pre-slaughter lairage

The objective of this study was to evaluate performance and carcass and meat characteristics of lambs fed a solution of crude glycerin plus water (100 g kg −1 of dry matter) (GLY) during feedlot and pre-slaughter lairage. Data were analyzed as a 2 × 2 factorial (GLY available or not in feedlot and GLY available or not in the slaughterhouse). We evaluated the following treatments (feedlot/slaughterhouse): GLY/GLY, GLY/water, water/GLY, and water/water (control). Lambs fed a balanced diet for 70 days in the feedlot. Slaughter started 12 h after the animals arrived at the slaughterhouse. Dry matter intake, feed conversion, average daily gain, and body weight of lambs fed GLY were similar to those of control lambs. Lambs receiving GLY ingested more water in the feedlot. At the slaughterhouse, water/GLY animals ingested more glycerin and water than GLY/water animals ingested water. Group GLY/GLY had lower drip loss in carcasses than the group GLY/water. The other carcass and meat characteristics (carcass weight, pH, subcutaneous fat thickness, ribeye area, color, water holding capacity, cooking losses, and shear force) were similar among treatments. Solution of crude glycerin plus water can be used as a dietary ingredient for lambs, since it improves hydration and does not change performance and carcass characteristics. This solution supplied as a pre-slaughter supplement does not improve carcass and meat characteristics.
