“…Also, the presence of secondary metabolites which according to Babayemi et al (2004a) could also affect the potency of rumen liquor for incubation. The presence of other phytochemicals such as phenol might be responsible for the low methane gas production (Faniyi et al, 2021). The methane production is lower compared to values of Babayemi (2005) for dry season forages but similar to values obtained by Ardiansyah et al (2016) for sorghum silage.…”

The study evaluated the nutritive potentials of 8 cultivars of sweet sorghum and their suitability as ruminant feedstuff. The sorghum cultivars were grown and harvested, each cultivar divided into 2 portions (whole plants and leaves), thereafter ensiled with the view of assessing their nutritive potentials vis-à-vis eco-friendliness for improved/sustained ruminant production. Nutrients and anti-nutrient compositions were assessed. Organic matter digestibility (OMD), methane gas production (CH4), short chain fatty acids (SCFA) and metabolizable energy (ME) were evaluated using in vitro gas production technique. Data generated were subjected to appropriate statistical analysis. From the results, parameters assessed were significantly (P<0.05) improved among the treatments. Ensiling significantly improved the nutritive qualities with respect to the cultivars. The assayed phytochemicals were at tolerable levels and would not hinder nutrients absorption, if fed to ruminants. Further, the in vitro degradability study revealed that whole plant of Samsorg-14 sweet sorghum cultivar and its silage have the best nutritive qualities (CP (7.66%; 9.16%), OMD (37.20%; 37.74%), SCFA (0.32; 0.36 umol/200MgDM), ME (4.91; 4.99 MJ/kgDM), respectively. Hence, Samsorg-14 sweet sorghum cultivar was the best of all the cultivars and could serve as protein/energy source in ruminants’ diet vis-à-vis its methanogenesis, which invariably could contribute to greenhouse gas emission.

“…The mode of action of tannins includes protein binding, which affects the growth of bacteria in the rumen and fermentation. They reduce the amount of protein available for bacteria, thereby reducing nitrogen excretion and decreasing bloating and internal parasites [20]. Nawab et al [18] noted that tannins could improve the production status, gut health, and immune status and reduce methane emission, which leads to improvement in the animal's overall performance.…”

There is a growing demand for livestock products and by-products due to an increase in the human population globally. Farmers utilize feed additives and antibiotics to enhance growth and alleviate diseases to meet this increasing demand for meat and meat products. Although antibiotic use as growth promoters (AGPs) in the livestock industry has brought about a positive increase in production, the industry has also been negatively affected by the development of bacteria resistant to antibiotics and the presence of chemical residues in meat and excreta. Due to this, concerns have risen as this poses a health risk. Resistant bacteria can be transmitted to humans by consuming meat from antibiotic-fed animals or environmental spread from animal wastes. Therefore, action is required to curb this issue because it is estimated that the annual losses in GDP and death toll globally could increase because of the continuous use of antibiotics in livestock production. Hence, this review aims to examine natural alternatives that have the potential to replace antibiotics for food safety, health, and environmental reasons. These could bring a satisfactory impact on nutrient absorption for growth together with health-stimulating virtues.

“…The total gas production (GP) during fermentation is positively correlated with the degradability of feed nutrients [39], and the degree of degradability is determined by the accessibility of feed components for rumen microorganisms, the activity of rumen microbes and the time available for fermentation [40]. That is why the total gas production and the rate of gas production are used as indicators to assess the degradability of feed and the functionality and adaptability of rumen microbes to the diet [41]. In this study, after 24 h of fermentation, the total gas production was higher in the diets with 10 (AH10) and 25% (AH25) alfalfa hay (AH) compared to the diet containing 100% hay (AH100), while after 48 h, the AH10 and AH100 diet presented similar levels of gas production, which were lower than the total gas obtained with the AH25 diet.…”

“…The production of CH 4 in the AH25 diet can be attributed to the higher total gas production that it presented, since feeds that present high total gas production generally also show a higher production of gas CH 4 [41] because in the rumen, the main biochemical process carried out by bacteria, protozoa and fungi is the fermentation of carbohydrates, and as a byproduct, they release short-chain fatty acids (SCFA; mainly acetic, butyric and propionic acids), metabolic hydrogen (H 2 ) and carbon dioxide (CO 2 ) [49]. Subsequently, methanogenic archaea remove H 2 by reducing CO 2 to CH 4 [42,50] to maintain low H 2 concentrations in the rumen [51], since, otherwise, inhibition of microbial growth and feed degradation would occur [52].…”

“…The rumen fermentation profile can be used as a measure or indicator of rumen health, feed digestibility and digestion efficiency. Rumen pH is vital for the persistence and stability of rumen microorganisms [69], while DMD, SCFA and metabolizable energy (ME) are useful as indicators of the digestibility and energy value of the feed [41,70]. In the current study, the pH at the end of fermentation ranged between 6.83 and 7.64, values that are within the range reported in other studies [71,72], and of the three diets, the AH25 diet had the highest pH, while the AH10 diet had the lowest pH.…”

The objective of this study was to evaluate the effect of different percentages of alfalfa (Medicago sativa L.) hay (AH) and doses of guanidinoacetic acid (GAA) in the diet on the mitigation of greenhouse gas production, the in vitro rumen fermentation profile and methane (CH4) conversion efficiency. AH percentages were defined for the diets of beef and dairy cattle, as well as under grazing conditions (10 (AH10), 25 (AH25) and 100% (AH100)), while the GAA doses were 0 (control), 0.0005, 0.0010, 0.0015, 0.0020, 0.0025 and 0.0030 g g−1 DM diet. With an increased dose of GAA, the total gas production (GP) and methane (CH4) increased (p = 0.0439) in the AH10 diet, while in AH25 diet, no effect was observed (p = 0.1311), and in AH100, GP and CH4 levels decreased (p = 0.0113). In addition, the increase in GAA decreased (p = 0.0042) the proportion of CH4 in the AH25 diet, with no influence (p = 0.1050) on CH4 in the AH10 and AH100 diet groups. Carbon monoxide production decreased (p = 0.0227) in the AH100 diet with most GAA doses, and the other diets did not show an effect (p = 0.0617) on carbon monoxide, while the production of hydrogen sulfide decreased (p = 0.0441) in the AH10 and AH100 diets with the addition of GAA, with no effect observed in association with the AH25 diet (p = 0.3162). The pH level increased (p < 0.0001) and dry matter degradation (DMD) decreased (p < 0.0001) when AH was increased from 10 to 25%, while 25 to 100% AH contents had the opposite effect. In addition, with an increased GAA dose, only the pH in the AH100 diet increased (p = 0.0142 and p = 0.0023) the DMD in the AH10 diet group. Similarly, GAA influenced (p = 0.0002) SCFA, ME and CH4 conversion efficiency but only in the AH10 diet group. In this diet group, it was observed that with an increased dose of GAA, SCFA and ME increased (p = 0.0002), while CH4 per unit of OM decreased (p = 0.0002) only with doses of 0.0010, 0.0015 and 0.0020 g, with no effect on CH4 per unit of SCFA and ME (p = 0.1790 and p = 0.1343). In conclusion, the positive effects of GAA depend on the percentage of AH, and diets with 25 and 100% AH showed very little improvement with the addition of GAA, while the diet with 10% AH presented the best results.
