“…Methane production was positively correlated with the OMD, NH 3 -N, numbers of microorganisms in the rumen, total VFA concentration and the (A + B) : P ratio. In agreement with our fermentation results, previous studies have reported Holotrich protozoa to be important for methanogenesis in the rumen (Belanche et al 2012;Belanche et al 2015;Kara et al 2018).…”

This study was aimed at determining the effects of propionic acid supplementation at doses of 0 (control group, PA0), 12, 24, 48 and 96 mM (PA12, PA24, PA48, and PA96) to concentrated mix feed on in vitro cumulative total gas production, methane emission, gas kinetics (potential gas production, (a + b)gas and gas production rate, cgas), estimated digestibility, estimated energy value and the end-products and variables of in vitro digestion (total bacteria count, the number of ciliate protozoa, volatile fatty acids, pH value and ammonia-N). Digestion treatments were carried out in an anaerobic in vitro fermenter for up to 96 h. The in vitro cumulative total gas production, (a + b)gas, estimated metabolic energy, estimated net energy lactation and estimated organic matter digestibility and ammonia-N concentration were decreased by propionic acid up to 96 mM (P < 0.05). In the in vitro fermenter fluid, total bacteria count, the total numbers of ciliate protozoa and the individual numbers of some ciliate protozoa (Entodiniinae, Isotricha spp. and Diplodiniinae) (P < 0.01) decreased linearly with increasing concentrations of dietary propionic acid. The total molar concentrations of volatile fatty acids decreased in response to propionic acid supplementation (P < 0.001). Dietary propionic acid elicited linear increases in the molar concentrations of propionic acid (P < 0.001) and butyric acid (P < 0.01) as proportions of total volatile fatty acids of the in vitro fermenter fluid. In contrast, molar proportions of acetic acid, the cgas, pH values and the numbers of Dasytricha sp. were not affected by dietary propionic acid supplementation (P > 0.05). The addition of 12–96 mM propionic acid to concentrated mix feed decreased methane emission from the rumen and negatively affected microbiota count, feed digestibility, proteolysis, and molar volatile fatty acid values in the rumen environment.

“…The amount was somewhat higher for the potato group, but this was probably not a major factor affecting the outcomes of the experiment. Kara et al [31] reported that no significant differences were observed between 4 and 8 mL of formic acid/kg of TMR on ruminal fermentation parameters. Additionally, based on the recommendation from EFSA [32], the formic acid supply to cows was lower than the maximum proposed dose (10,000 mg (8.2 mL) of formic acid/kg of TMR).…”

Vegetable by-products have great potential for use as animal feeds and thus could improve the sustainability of the food system. The objective was to evaluate the milk production potential of potato by-product (PBP) replacing cereal grains in grass silage-based total mixed ration (TMR). Additionally, a laboratory scale experiment was conducted to assess the effect of PBP and chemical preservatives on the aerobic stability of TMRs. A change-over dairy cow feeding experiment was conducted to evaluate the inclusion of 135 g/kg (on a dry matter (DM) basis) of PBP in TMR. Additionally, the aerobic stability of TMR was evaluated by preparing TMRs with increasing levels of PBP and treated with different doses of formic and propionic acid or salt-based preservatives. The inclusion of PBP in dairy cow diets decreased feed intake, but organic matter digestibility was greater in the PBP diet, resulting in only slightly decreased production (milk protein 1435 vs. 1363 g/day, p < 0.05; milk lactose 1716 vs. 1606 g/day, p < 0.05). The aerobic stability of TMR was negatively affected by the inclusion of PBP, but it could to a limited extent be prolonged using chemical preservatives. The inclusion of PBP decreased feed intake and milk production to some extent when included in the diet of high-producing dairy cows. The utilization of PBP may, however, be justified from a sustainability point of view, as it provides a way to circulate the nutrients of a non-human edible feed material back into the food chain.

Stoichiometric models for prediction of enteric methane production

et al. 2022

This study aimed to empirically evaluate the adjustment quality of two stoichiometric models of methane production from diets that used different rumen fermentation modulators. We used the models proposed by Moss et al. (2000) and Blümmel et al. (1997). The data set consisted of 169 observations of in vitro methane production and volatile fatty acids (acetate, propionate, and butyrate) from dissertations, theses, and scientific articles. The model’s adequacy evaluation was only possible through combination of several statistical analyzes. The models were unable to predict the enteric methane precisely and accurately. Despite this, the model proposed by Moss et al. (2000) showed a better fit based on the mean bias (% of observed, MB), MEF, RMSEP, Cb and CCC measures compared to the model proposed by Blümmel et al. (1997). However, both models presented strong evidence against the general hypothesis H0: a = 0 & b = 1. Thus, the model proposed by MOSS et al. (2000) was more efficient, whereas the model by Blümmel et al. (1997) showed a better fit for diets with high availability of H2.
