“…In accordance with the present work, Avila-Stagno et al (2013), Chanjula et al (2015), andOliveira Filho et al (2015) found no differences in DM and nutrient intake in lambs fed diets with inclusion levels of 21, 20, and 7 % CG in DM, respectively.…”

This study aimed to evaluate the effect of the level of crude glycerin (CG) on in vitro fermentation kinetics (0, 20, 40, 60, and 80 g/kg DM of sugar cane silage), on in vitro neutral detergent fiber (NDF) degradation (0, 30, 60, and 90 g/kg DM of sugar cane silage), and intake and digestibility of nutrients and nitrogen balance (0, 20, 55, 82, and 108 g/kg DM of sugar cane silage) in lambs. The in vitro trials were conducted in a completely randomized design with three repetitions. The in vivo trial was conducted in a Latin square design with five repetitions (5 × 5). For variables in which the F test was considered significant, the statistical interpretation of the effect of CG substitution levels was carried out through regression analyses. Kinetic parameters were not affected by CG inclusion. On in vitro NDF degradation, a significant effect of CG levels was observed on the potentially degradable fraction of NDF, the insoluble potentially degradable fraction of NDF, and the undegradable NDF fraction. The intake and digestibility of nutrients and nitrogen balance were not affected by CG inclusion. The CG levels change in vitro NDF degradability parameters; however, there were no changes in animal intake, digestibility, and nitrogen balance with the inclusion levels used.

“…Furthermore, McEachern et al (2009) revealed that replacing cottonseed meal with 60 % DDGS in lamb growth did not alter PUN. The current values were within the normal range for goats (McEachern et al 2009;Chanjula et al 2015) and give no indication of problems with using CBW in the feeding program. The PUN concentrations could be useful as an indicator of protein status within a group of goats and could help to fine-tune diets or identify problems with a feeding regime (McEachern et al 2009).…”

This experiment was conducted to investigate the effects of various levels of cassava bioethanol waste (CBW) on nutrient intake, digestibility, rumen fermentation, and blood metabolites in growing goats. Twelve crossbred, male (Thai Native × Anglo Nubian) growing goats with initial body weight (BW) of 20±3 kg were randomly assigned according to a completely randomized design (CRD). The dietary treatments were total mixed ration (TMR) containing various levels of CBW at 0, 10, and 20 % dry matter (DM). CBW contained crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), and acid detergent lignin (ADL) at 11, 69, 47, and 23 % DM, respectively. The TMR diets were offered ad libitum and contained CP at 15 % DM. Inclusion of CBW at 10 % DM in TMR did not alter feed intake (g DM and g/kg BW(0.75)) and CP intake when compared to the control fed group (0 % CBW). Total OM intake was lower in the 20 % CBW group than in the others (P < 0.01). The digestibility coefficients of DM, OM, CP, and NDF were not changed for the TMR including 10 % CBW compared to the control group (P > 0.05) whereas when 20 % CBW was incorporated to diet, intermediate digestibility coefficients were decreased. Average ruminal pH values ranged from 6-7. Rumen NH3-N and PUN concentration at 0, 3, and 6 h post-feeding were not significantly different among treatments (P > 0.05). Thus, inclusion of 10 % CBW in TMR diets does not adversely affect nutrient intake, digestibility, rumen fermentation, and blood metabolite in fattening goats, and CBW may be effectively used as an alternative roughage source in the diets of goats.

“…In most of these studies, glycerol replaced corn grain in the concentrate diets. In contrast, feed intake was not affected when glycerol was fed to finishing lambs (Gunn et al, 2010a), goats (Chanjula et al, 2015), Holstein bulls (Mach et al, 2009) or dairy cows (Omazic et al, 2013). The non-consistent effects of glycerol on feed intake can be explained by purity and amount of glycerol used, method of administration as well as composition of the diets (Wang et al, 2009b;Omazic et al, 2013).…”

Two experiments were conducted to evaluate the effects of replacing corn with an increasing concentration of high-purity glycerol (>99%) on growth performance, economical efficiency, blood constituents and nutrient digestibility of growing lambs. In experiment one, 24 male lambs (initial BW=33.6±6.0 kg; age=6.75±0.75 months) were randomly assigned to one of the three experimental treatments containing 0%, 5% or 10% glycerol to replace corn in concentrate. In experiment two, nine lambs (initial BW=44.7±2.2 kg, age=8.84±0.32 months) were used in a digestion trial with three treatments (three lambs per treatment) with glycerol replacing corn at 0%, 5% or 10% in the concentrate. Total dry matter (DM) intake decreased quadratically (P=0.003) with increasing concentration of glycerol in the diet. Lambs fed glycerol diets had greater average daily gain (P=0.005) and better feed efficiency (P=0.002) compared with the control. Feed costs were also reduced with glycerol inclusion. Glycerol supplementation did not affect serum concentrations of total protein, albumin, globulin, total lipid, cholesterol and glucose concentrations. Glycerol supplementation had no effect (P>0.05) on organic matter and CP digestion, but improved DM (P=0.0003), crude fiber (P=0.10), ether extract (P=0.0002) and nitrogen-free extract (P=0.05) digestion. In conclusion, glycerol can replace corn up to 10% of DM in the diets of growing lambs.
