“…Increases in HCW and LM with an increasing proportion of WCS are consistent with changes in ADG and final live weight (Félix-Bernal et al, 2014;Hernández et al, 2017). The tendency of a lower dressing percentage of lambs receiving diets with a greater amount of SPR reflects the comparatively low apparent digestibility of SPR fiber, resulting in greater ruminal fill (Vinhas-Voltolini et al, 2011).…”

Sixty-four Pelibuey × Katahdin male lambs (14.3± 2.2 kg initial live weight) were used in an 84-d growing-finishing trial to evaluate optimal levels of inclusion of whole cottonseed (WCS) in a broom sorghum panicle residue-based diet. Dietary treatments consisted in partial replacement of broom sorghum panicle residue (SPR) and tallow with 0, 10, 20 or 30% WCS. Control diet contained 66.5% PSR and 3% tallow, and replacing were as follows: 10% of WCS replaced 9% SPR and 1% tallow (WCS10), 20% WCS replaced 18 SPR and 2% tallow (WCS20), and 30% WCS replaced 27% SPR and 3% tallow (WCS30). Inclusion of WCS increased (quadratic component, P=0.03) average daily gain (ADG), dry matter intake (DMI) and gain efficiency. However, with increasing level of WCS substitution the observed/expected dietary net energy ratio decreased (linear effect, P<0.01). The estimated NEm value for WCS determining by the replacement technique at the 10, 20 and 30% levels of inclusion were 2.48, 2.23, and 2.15 Mcal/kg, respectively. Consistent with the increased final weight, hot carcass weight and longissimus muscle area were increased (linear effect, P≤0.03) with increasing level of WCS inclusion. While, dressing percentage and fat thickness tended to increase (linear effect, P=0.10) with increasing WCS level. The partially replacement of broom sorghum panicle residue and tallow by up to 20% inclusion of WCS in finishing diets for lambs enhances ADG, gain efficiency, carcass weight, and LM area. However, the net energy value of WCS decreases with level of inclusion greater than 10%.

“…The increase in FT and KPH pelvic fat is consistent studies evaluating fat supplementation in finishing diets for feedlot cattle (Zinn & Jorquera, 2007;Donicht et al, 2011). However, this response has been less consistent in feedlot lambs (Félix-Bernal et al, 2014;Estrada-Angulo et al, 2017). These inconsistencies may be due in part to degree of finish (shorter finishing period in which fats were supplemented).…”

The objective of this experiment was to compare the effects of dietary supplementation with cooking grease recovered from rinse-trap water lines (rinse-trap grease; RTG) versus conventional supplemental fats (tallow; TL, and yellow grease; YG) on 84-d growth performance, dietary energy, and carcass traits of feedlot lambs. Forty-eight Pelibuey × Katahdin lambs (27.7 ± 3.4 kg) were assigned in a randomized complete block design to evaluate: 1) basal diet without supplemental fat (Control); 2) 4% TL; 3) 4% YG, and 4) 4% RTG. Supplemental fats replaced maize in the control diet. Rinse-trap grease contained greater moisture (16.5 vs 0.92%) and impurities (3.6 vs 0.56%), and less total fatty acid (64.90 vs 89.60%) than that of conventional fats (TL and YG). Daily weight gain and gain efficiency were similar for control and RTG supplemental lambs, whereas ADG and gain efficiency were greater for lambs fed conventional fats than control or RTG-supplemented lambs. Both dietary net energy (NE) as well as ratio of observed-to-expected dietary NE were 4% greater for lambs supplemented with conventional fats vs RTG. Supplemental fat increased fat deposition but did not affect any other carcass measures or non-fat visceral mass. Estimated NE value for RTG was 57% of the average NE value (6.11 Mcal/kg) of tested conventional fats. Supplementation with RTG does not affect diet acceptability, and accordingly, is a suitable energy source for feedlot lambs. However, due to its lower total fatty acid content, its energy value is much lower than conventional supplemental fats.
