Short-term use of monensin and tannins as feed additives on digestibility and methanogenesis in cattle

Abstract

RuminantsFull-length research article Short-term use of monensin and tannins as feed additives on digestibility and methanogenesis in cattle ABSTRACT -The objective was to assess the effects short-term use of monensin and Acacia mearnsii tannins as feed additives on nutrient intake, digestibility, and CH 4 production in cattle. Six rumen-cannulated Holstein cows were distributed in two 3×3 Latin square experimental design, and each experimental period lasted 21 days. The basal diet was composed of corn silage and concentrate in a 50:50 dry matter (DM) basis proportion. Treatments were control, monensin (18 mg kg −1 of DM), and tannin-rich extract from Acacia mearnsii (total tannins equivalent to 6 g kg −1 of DM). Nutrient intake and apparent digestibility coefficients were not affected by the addition of monensin or tannins to diets. However, tannins showed a tendency to reduce crude protein digestibility. Monensin decreased CH 4 emission by 25.6% (g kg −1 of body weight) compared with the control treatment. Monensin is more effective than Acacia mearnsii tannins in reducing CH 4 emissions in the short term, considering a diet of the same roughage:concentrate proportion for cattle.

Enteric Methane Emissions Prediction in Dairy Cattle and Effects of Monensin on Methane Emissions: A Meta-Analysis

“…Out of 41 papers, 17 articles were excluded for the following reasons: summary papers (4), no CH 4 emission measurements (2), no monensin/treatment effect results reported (2), without control measurements (3), conference papers as there were duplicate publications of the similar study (2), conference paper only reported an abstract, simulation papers (2), and paper that investigated the effects of monensin when mixed with other feed additives. The final database had a total of 24 papers that met the criteria and remained in the database; however, 13 were related to beef cattle [ 29 , 36 , 38 , 39 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 ] and 11 were related to dairy cattle [ 8 , 9 , 28 , 30 , 31 , 32 , 33 , 34 , 53 , 54 , 55 ]. Then, beef cattle papers were excluded from the database.…”

“…Enteric CH 4 mitigation strategies in ruminants include but are not limited to, dietary feed formulation changes [ 7 ], the use of feed additives/rumen modifiers such as ionophores [ 8 ], essential oils [ 9 ], plants extracts [ 10 ], plant secondary metabolites (e.g., tannins) [ 11 ], and chemical inhibitors [ 12 ] along with genetics and management [ 13 ]. All these strategies have been shown to reduce enteric CH 4 production either directly or indirectly; however, consistent and cost-effective strategies are not yet established [ 2 ].…”

Towards Sustainable Livestock Production: Estimation of Methane Emissions and Dietary Interventions for Mitigation

“…Stall-fed Holstein cows treated with 18 mg/kg of dry matter monensin showed a 24.3% decline in CH 4 production when expressed in g/day. According to the authors, this reduction could be due to the positive effect of monensin on the Gramnegative bacteria that produce propionate and due to the negative effect of monensin on the acetate and hydrogen-producing bacteria such as Eubacterium, Lactobacillus, and Streptococcus [115]. Likewise, feedlot-type penned Angus steers fed with 33 mg/kg monensin showed a 30% reduction in enteric CH 4 production (measured using the SF6 technique) along with a numeric reduction in ciliated protozoan populations [116].…”

“…Травы и растительные экстракты использовались в течение длительного времени и в ветеринарной медицине [10]. Они привлекают все больший интерес в качестве альтернативной стратегии кормления для замены антибиотиков и стимуляторов роста, положительно влияют на окислительную стабильность мяса и его состав [10,7,8,9].…”
