“…According to our results, the higher dose of glycerol (1000 ml) also failed to increase the butyrate concentration in rumen fluid. Similarly, Kass et al (2012) found no significant effect of 1 kg of glycerol on rumen fermentation, but higher amounts (2 and 3 kg) significantly increased both propionic and butyric acids. On the other hand, Boyd et al (2013) found increased propionate with 200 g of glycerol and Abo El-Nor et al (2010) found decreased acetate and increased butyrate with a glycerol concentration of 36 g · kg -1 DM.…”

“…At present, thanks to biodiesel production, large quantities of glycerol (10% by weight of processed oil) will become available at a much lower price. This has revived interest in glycerol for treatment of ketosis in ruminants and as a feed additive for fresh cows (Fischer et al, 1973;DeFrain et al, 2004;Kass et al, 2013) or as a substitute for maize or barley (Kass et al, 2012;Wilbert et al, 2013). The results of experimental work with supplementation of glycerol and propylene glycol in fresh cows differ.…”

“…Glycerol is known to improve the energy balance in lactating dairy animals by increasing dry matter intake and reducing NEFA levels in blood. However, Kass et al [9] did not find increased milk production in dairy cows even dry matter intake increased upon using glycerol at 0, 5, 10 and 15% in diet dry matter in replacement of barley meal on iso-energetic basis. The metabolic shift occurred upon glycerol supplementation that does not favor gluconeogenesis at the mammary gland from propionate.…”

The objective of this paper was to determine the opportunities of improving milk productivity and altering the milk composition through nutritional interventions. The increase in the nutraceutical value of milk is expected through dietary modifications of the animal. Feeding high concentrate diets combined with dietary fat can be used to modify the FA profile of milk, without negative effect on milk yield and milk fat or protein contents. Their effects may be complementary, at least for trans fatty acids. The profile of trans isomers relative to total trans-C18:1 seems dependent on the source of dietary fat. Feeding oilseeds and/ or novel fat supplements to ruminants can be used to modify the lipid metabolism in the mammary gland in modulating the secretion of fat and the profile of milk fatty acids. Feeding novel fatty acid sources the nutritive value of milk can be enhanced by decreased atherogenic saturated FA in milk and increased t 11 -C 18 : 1 (trans vaccenic acid), and c 9 ,t 11 -C 18:2 (geometric and positional isomer of conjugated linoleic acid (CLA) in milk, which are considered as positive for human health. Feeding bypass/ rumen protected sources of fatty acids and amino acids may help in meeting the need of higher milk production, and in modulating milk composition through increase availability of fatty acids and amino acids in circulation with synchronized extraction of desired nutrient by mammary gland for milk constituents synthesis. Milk may be used as delivery system of anticarcenogens (CLA and polyphenols) for human health. Therefore, nutritional manipulations have several opportunities in improving milk production, modifications of milk composition and fatty acid profile. The improved milk productivity is desired in line with increased human population with minimum environment degradation thereby nutritional manipulations are directed to enhance milk production without increasing dairy animal populations with reduced greenhouse gasses emissions from ruminant agriculture.

“…Using pure source of glycerol resulted in no change in DMI (Chung et al, 2007;Donkin et al, 2009;Lomander et al, 2012). However, Kass et al (2012) reported an increase in intake by increasing crude glycerol levels.…”

“…Other than the conflicting results on DMI and performance of cows which could be due to the purity and the level of the glycerol used and/or the severity of negative energy balance in the experimental animals, all the studies with the exception of Kass et al (2012) who used only eight primiparous cannulated cows and fed crude glycerol, have been carried out on multiparous dairy cows. First-lactation cows have lower energy balance because they eat less and have energy requirements for growth in addition to lactation (Lucy et al, 2001).…”

The aim of this study was to evaluate the glucogenic property of glycerol supplementation in the dairy cow's diet. Sixty primiparous cows (control, n=30, and glycerol supplemented, n=30) were used to measure milk yield and components, blood hormone and metabolite profiles, and body condition score. Feed intake and apparent total-tract digestibility were also measured using 10 primiparous cows (control, n=5, and glycerol supplemented, n=5). Dry glycerol was top dressed at 250 g/day/cow from parturition to 21 days postpartum. Average feed intake, milk yield and components were not affected by glycerol supplementation. Apparent total-tract digestibility of organic matter and neutral detergent fibre were not influenced by dry glycerol supplementation, but lipid digestibility was greater (p=0.01) in cows fed glycerol. The serum concentration of glucose and insulin tended to be higher in dry glycerol-supplemented cows (p=0.1; p=0.06, respectively). While, serum concentrations of nonesterified fatty acids and β-hydroxybutyrate were not affected. Supplemented cows had lower body condition loss during weeks 1 to 5 after calving (p=0.09). The glucogenic effect of glycerol did not affect milk yield during the first 3 weeks of lactation. However, daily milk yield during the 13 weeks recording period was higher in the glycerol-supplemented cows (28.5 vs. 30.3 kg, p<0.001). Percentages of cows cycling at the planned breeding date was greater (p=0.01) for cows fed dry glycerol. The results demonstrated that feeding dry glycerol as a glucogenic supply could be useful in saving body reserves and improving energy balance of primiparous Holstein dairy cows during the early postpartum period.Additional key words: milk production; feed intake; apparent total-tract digestibility; body condition score; blood metabolites.
