Aims: The potential of gallnut tannin (GT) and Lactobacillus plantarum (LP) on fermentation characteristics, in vitro ruminal methane (CH ) production and microbiota of alfalfa silage was investigated.
Methods And Results: Alfalfa was ensiled with GT (20 and 50 g kg dry matter [DM]) and LP (3 × 10 CFU per gram fresh matter) alone or in combination for 60 days. The GT and LP alone or in combination decreased DM losses, pH and non-protein nitrogen contents of alfalfa silage. All additive treatments decreased ruminal CH production, and increased propionic acid molar proportions and Fibrobacter succinogenes numbers. The LP treatment increased nutrient degradation, cellobiase, pectinase and protease activities, and Prevotella ruminicola abundance, whereas high-dose GT treatment inhibited these variables. Importantly, LP together with GT alleviated the adverse effects of high-dose GT supply alone by enhancing pectinase and protease activities as well as Rumincoccus flavefaciens and P. ruminicola growth.
Conclusions: Combination of GT and LP can be used as an efficient additive to improve silage quality and utilization by ruminants.
Significance And Impact Of The Study: Using GT-LP combination has practical implications, particularly concerning effects of tannins on ruminal CH mitigation, which may alleviate inhibitory effects of tannins on feed digestion through modulating ruminal microbiota.

Alfalfa silage due to its high protein can lead to easier feeding management, but its high proportion of rumen-degradable protein can reduce rumen nitrogen utilization. Nevertheless, increasing dietary energy can enhance ruminal microbial protein synthesis. Thirty-two Suffolk female sheep were used in this study, with a 2 × 2 factorial arrangement of treatment.

This study examined the effects of supplementing dairy cows with a mixture of essential oils on enteric CH emissions, apparent total-tract nutrient digestibility, N utilization, and lactational performance (production, components and efficiency). Thirty-two multiparous lactating Holstein cows were used in a randomized complete block design. Cows averaged (mean ± SD) 95 ± 15.

Phycocyanin is a water-soluble pigment protein extracted from prokaryotes such as cyanobacteria and has strong antioxidant activity. As a silage additive, it is expected to enhance the antioxidant activity and fermentation quality of alfalfa silage. This study revealed the effects of different proportions of phycocyanin (1%, 3%, 5%) on the quality, bacterial community and antioxidant capacity of alfalfa silage.

Reducing greenhouse gas (GHG) emissions from livestock is a crucial step towards mitigating the impact of climate change and improving environmental sustainability in agriculture. This study aimed to evaluate the effects of Yucca schidigera extract, chitosan, and chitosan nanoparticles as feed additives on in vitro GHG emissions and fermentation profiles in ruminal fluid from bulls. Total gas, CH, CO, and HS emissions (up to 48 h), rumen fermentation profiles, and CH conversion efficiency were measured using standard protocols.

Sizes and rates of potentially digestible (B) and undegradable (C) pools of amylase-treated neutral detergent fiber (aNDF) are used to predict ruminal aNDF digestibility (aNDFD%) in widely used dairy cattle diet formulation programs. An exponential 3-pool model (3P) has been suggested for estimating digestion kinetic parameters for this purpose, however, the approach has not been compared with using a simpler exponential 2-pool model (2P), nor with using commercial laboratory (lab) data on which application would rely, nor on model impact on predictions of aNDFD% which is the aim of their application. Our objective was to determine whether 2P or 3P most accurately and efficiently characterizes aNDF digestion kinetics and if the models differed in predicted aNDFD%.
