“…The other half of the ground samples was used to evaluate Convert HD364 grass as for the potential production of total gas, CH 4 and carbon dioxide (CO 2 ), following a methodology adapted and proposed by Paschoaloto et al (2016), where the gas produced over a 24-hour period is expressed as mL g -1 of DM. The gas concentration was MEURER et al…”

The increased world population has raised the demand for animal proteins, forcing livestock to become productive, efficient, and environmentally sustainable. This study aimed to assess the effect of weed coexistence on productivity, nutritional quality, and potential production of greenhouse gases (GHG) by Convert HD364 grass (Urochloa hibrida cv. Mulato II) under pasture renovation conditions. The experiment was carried out in a randomized block design with four replications and treatments consisting of eight coexistence periods: 0, 15, 30, 45, 60, 75, 90, and 120 days after seedling emergence. Phytosociological assessments were performed in the weed community at the end of each coexistence period. The Convert HD364 grass was assessed for the morphological and chemical-bromatological parameters and for the GHG emission potential. Productivity, nutritional quality, and energy value of the Convert HD364 grass decreased proportionally with the increased period of weed coexistence. The non-coexistence with weeds results in a better in vitro digestibility of organic matter and, consequently, decreases the potential of GHG emission by the dry matter of the Convert HD364 grass.

“…Despite the lack of significant difference in propionic acid concentrations, the combination crude glycerine with essential oil promoted an increase of 17% in this acid, fact that decreased the C2: C3 ratio in the rumen. Although there are also evidence that crude glycerine may have a detrimental effect on the growth of structural carbohydrate fermenting bacteria (AbuGhazaleh, Abo El‐Nor, & Ibrahim, ; Roger, Fonty, Andre, & Gouet, ), resulting in reduced fibre digestibility and CH 4 production (van Cleef et al, ; Homem Junior et al, ; Paschoaloto et al, ), crude glycerine does not impair the consumption, performance or carcass characteristics of feedlot cattle (van Cleef et al, ) and, when combined with essential oil, has shown even better results (Cruz et al, ; Prado et al, ; Silva et al, ; Valero, Prado, et al, ; Valero, Torrecilhas, et al, ).…”

“…Crude glycerine is a by‐product from the biodiesel industry used as an alternative energy source in animal diets, mainly as a replacement for corn grain. Promising results were reported for the inclusion of up to 20% DM in diets for ruminants without affecting animal health and performance (Almeida et al, ; Carvalho et al, ; van Cleef et al, ; Paschoaloto et al, ).…”

The effects of adding crude glycerine with sodium monensin or essential oils to beef cattle diets on the intake, degradability of DM and nutrients, rumen concentration of volatile fatty acids (VFA) and in vitro gas production were evaluated. Five ruminally cannulated Nellore steers were randomly assigned to a 5 × 5 Latin square design. The treatments were as follows: CONT, without crude glycerine and additives; EO, with essential oils and without crude glycerine; MON, with sodium monensin and without crude glycerine; EOG, with essential oils and crude glycerine; MONG, with sodium monensin and crude glycerine. Treatments with essential oil and sodium monensin increased the NDF and STC intake and the DM degradability. When crude glycerine was combined with either sodium monensin or essential oil, there was a reduction in DM, NDF and STC intake and an increase in DM and CP degradability of the diets. The adding crude glycerine to essential oil diets reduced the CH4 production. Sodium monensin treatments reduced DM and NDF intake and the production of total gas, CH4, total VFA and acetic acid concentration. In conclusion, the adding crude glycerine (200 g/kg DM) with either sodium monensin (0.03 g/kg DM) or essential oil (0.5 g/kg DM) can be utilized in diets for Nellore cattle without causing detrimental effects on feed intake and improving the DM degradability.

“…However, no experimental results are available to confirm the hypothesis of alteration in the methanogenic archae population in the rumen. Paschoaloto et al (2016) carried out successive in vitro studies with different CG levels with varying concentrate: roughage diets. The authors concluded that production of methane does not depend on the CG inclusion level rather it depends on NDF content of the substrate.…”

Increased concern on greenhouse gas emission, concomitant global warming and decreasing fossil fuels have created the necessity to find an alternative source of energy for the transportation vehicles. Biodiesels is an alternative renewable fuel source, which releases less carbon dioxide, carbon monoxide, sulfur and nitrogen oxides upon combustion. These environmental friendly features of biodiesel make it a potential alternative to the conventional one. Biodiesel can be extracted from the edible or non -edible source of triglycerides. During this extraction process, crude glycerol (CG) is obtained at the rate of 10% as a byproduct of trans-esterification reaction. Chemically, CG so obtained is composed of catalysts, salts and fatty acids. Purification of CG to >95% involves the cost (0.28 USD/L production) and time consuming process. Hence, economical management of CG is the need of hour, one such alternative way is its entry in animal food chain as an energy source. Basically, glycerol is a glycogenic intermediate product of fat digestion converted to glucose by the action of key enzyme glycerol kinase. The CG undergo glycolysis and TCA cycle to liberate ATP. The digestible and metabolizable energy content of CG are comparable with the commonly used cereal grains in livestock feeding. Thus, CG acts as a bridging gap between the biodiesel industry and livestock production. Studies have showed that CG
