“…The increases in ruminal propionate:acetate ratio previously reported for animals on glycerol diets (Carvalho et al, 2011) may explain these changes, because acetate represents the main precursor to milk fat. Alternatively, other authors suggest that a reduction in NEFA plasma concentrations of animals fed glycerol may indicate lower lipid mobilization and lipolysis, thus explaining the reduction in milk fat (Kass et al, 2012;Kupczynski et al, 2012). Nevertheless, it was observed that milk fat content showed a quadratic effect, increasing back with 30% dietary glycerin.…”

An increasing worldwide interest in alternative fuel sources and in a more diversified energy matrix has provided incentives for the biodiesel industry, generating large amounts of the by-product crude glycerin, a potential alternative feed for dairy cows. A replicated 3×3 Latin square study was conducted to evaluate the effects of high concentrations of crude glycerin on dry matter intake, milk yield and composition, milk fatty acid profile, and blood metabolites of medium-yield cows. Ruminally cannulated Holstein cows (n=6; 587 ± 39 kg of body weight; 114 ± 29 d in milk; and 20 ± 1.5 kg/d milk yield) were used in the study. The experimental period included 2 wk for adaptation and 1 wk for data collection. Cows were fed diets containing 0 (control), 15, or 30% crude glycerin (83% glycerol). Cows were milked, milk weights were recorded twice daily, and milk samples were collected for milk quality analyses at d 18 and 19 in each experimental period. Feeding cows with crude glycerin linearly decreased dry-matter intake, the 3.5% fat-corrected milk, and the solid-corrected milk yield. Hepatic enzymes were not affected by dietary treatments, except gamma-glutamyl transferase, which was decreased with the 15% crude glycerin diet. Serum glucose and albumin showed quadratic effect with increasing inclusion of crude glycerin. Plasma cholesterol as well as total protein linearly decreased with increasing inclusion of crude glycerin. Milk fat concentration and yield showed a quadratic effect of treatments. Solid yield decreased linearly with increasing inclusion of crude glycerin. Odd-chain fatty acids and conjugated linoleic acid in milk fat linearly increased with addition of crude glycerin in the diets. Together, these results suggest that crude glycerin has potential to replace corn; however, feeding diets in which corn is replaced with crude glycerin at 30% of dietary DM greatly reduces animal performance.

“…In our own studies, we compared the effect of short-term (7 day antepartum to 7 day postpartum) administration in cows of propylene glycol and glycerol (99% pure) in two forms: as an addition to the total mixed ration (TMR) (topdressed) and oral drenching [ 53 ]. Both additives were administered at 300 mL/d.…”

In sheep studies, it has been established that a positive effect on growth rates, feeding behavior, and blood metabolites is achieved with no higher than 4.7% DM [ 69 ].…”

“…A number of studies indicate that it is possible to administer crude glycerol up to 15% DM to dairy cows without negative effects on milk yield [ 33 , 64 , 66 ]. The commonly used doses of glycerol do not significantly affect DMI, milk yield, or milk composition in dairy cows [ 33 , 53 ]. Donkin et al [ 33 ] showed that cows fed the 15% glycerol diet had decreased DMI for the first 7 days of the experiment.…”

The aim of this paper is to review and systematize the current state of knowledge on glycol metabolism in cattle. Glycerol, derived from biodiesel production, must be purified in order to be a useful product for feeding livestock. The use of glycerol in the feeding of ruminants can be justified for several reasons: (i) it is a source of energy in the ration, (ii) it is a glucogenic precursor, and (iii) it may have an effect on milk composition. The high energy value of glycerol provides the opportunity to use this raw material as a partial grain substitute in cattle feed rations. Dietary supplementation of glycerol is associated with increased propionate, butyrate, valerate, and isovalerate concentrations in the rumen. Glycerol can be used at up to 10%–15% of the dietary dry matter (DM) and is well-established as a treatment for ketosis in cows. Glycerol increases plasma glucose and may reduce non-esterified fatty acids and β-hydroxybutyrate levels. The use of glycerol does not have a clear effect on DM intake, milk yield, or milk composition. However, some authors have reported an increase in milk yield after glycerol supplementation associated with decreased milk fat concentration. It is also possible that the concentration in the milk of odd-chain fatty acids and cis-9, trans-11 conjugated linoleic acid may increase after glycerol application.
