Dynamics of the ruminal microbial ecosystem, and inhibition of methanogenesis and propiogenesis in response to nitrate feeding to Holstein calves
(Elsevier, 2021-12)
It is known that nitrate inhibits ruminal methanogenesis, mainly through competition with hydrogenotrophic methanogens for available hydrogen (H2) and also through toxic effects on the methanogens. However, there is limited ...
Performance of semi-continuous anaerobic co-digestion of poultry manure with fruit and vegetable waste and analysis of digestate quality: A bench scale study
(2018)
Poultry manure (PM) can contain ammonium and ammonia nitrogen, which may inhibit the anaerobic process. The aim of this work was to evaluate the performance of anaerobic digestion of PM co-digested with fruit and vegetable ...
Effect of quebracho-chestnut tannin extracts at 2 dietary crude protein levels on performance, rumen fermentation, and nitrogen partitioning in dairy cows
(Elsevier, 2016-06)
Our objective was to determine the effects of a tannin mixture extract on lactating cow performance, rumen fermentation, and N partitioning, and whether responses were affected by dietary crude protein (CP). The experiment ...
Dietary nitrate metabolism and enteric methane mitigation in sheep consuming a protein-deficient diet
(CSIRO Publishing, 2019-09-20)
It was hypothesised that the inclusion of nitrate(NO3 –) or cysteamine hydrochloride (CSH) in a protein deficient diet (4.8% crude protein; CP) would improve the productivity of sheep while reducing enteric methane (CH4) ...
Robust regulation of alkalinity in highly uncertain continuous anaerobic digestion processes
(2011)
Reliable corner detection is an important task in determining the shape of different regions within an image. Real-life image data are always imprecise due to inherent uncertainties that may arise from the imaging process ...
Salvia albicalyx and Salvia topiensis (Lamiaceae), two new species from Durango, Mexico
(2012)
The saturated Output-Feedback (OF) control problem for a class of four-state anaerobic digestors with volatile fatty acids (VFAs) measurement is addressed. The reactor must operate about an optimal steady-state, with maximum ...
Anaerobic treatment of Tequila vinasses in a CSTR-type digester
(2010)
Tequila industries in general produce great volumes of effluents with high pollutant loads, which are discharged (untreated or partially treated) into natural receivers, thus causing severe environmental problems. In this ...
Some ants genera (Hymenoptera: Formicidae) observed in three isles at the mouth of the Gulf of California, Mexico [Algunos géneros de hormigas (Hymenoptera: Formicidae) observados en tres islas de la boca del Golfo de California, México]
(2002)
This paper presents the practical implementation of a new robust interval observer on a 1m3 continuous fixed bed anaerobic reactor used for the treatment of industrial wine distillery wastewater. This interval observer is ...
Anaerobic treatment of Tequila vinasses in a CSTR-type digester
(2010)
Tequila industries in general produce great volumes of effluents with high pollutant loads, which are discharged (untreated or partially treated) into natural receivers, thus causing severe environmental problems. In this ...
Hormones and monensin use to improve pregnancy rates in grazing lactating beef cows in the semiarid region of Argentina
(2018-03)
The objectives of this study were 1) to determine the effect of monensin treatment, alone or combined with a hormonal estrus synchronization treatment, on the pregnancy rate of lactating beef cows, and 2) to evaluate the ...
