“…Recently, Piñeiro‐Vázquez et al. () observed that only doses of 40 g/kg DM of condensed tannins reduced feed intake in heifers. Thus, the condensed tannins found in PLP diets might be too low to have negative effects on feed intake and consequently on growth performance.…”

A study with finishing lambs assessed the effect of dietary inclusion of Prosopis laevigata pods (PLPs) on performance, carcass characteristics, meat traits and fatty acid profile of subcutaneous fat. Twenty-one Rambouillet lambs (27.0 ± 3.0 kg BW) were assigned to one of three experimental diets with 0, 150 and 300 g PLP/kg DM. Evaluation of growth performance lasted 49 days. The experimental design was completely randomized and analysed with a mixed model. Lambs fed diets with 0, 150 and 300 g PLP had similar growth performance. Lambs fed diets with 300 g PLP/kg DM had better (p < 0.05) carcass yield and classification, less (p < 0.05) fat deposition and lower lightness (L*) value (p < 0.05) in meat than lambs fed diets with 0 and 150 g PLP/kg DM. Saturated fatty acids (palmitic and stearic) decreased (p < 0.05) and unsaturated fatty acids (oleic and linoleic) increased (p < 0.05) in subcutaneous fat of lambs fed diets with 150 and 300 g pods as compared with lambs not fed PLP. Prosopis laevigata pods are a safe feedstuff that can replace a third of conventional ingredients and reduce feed costs in growing lambs. Addition of PLP reduced (p < 0.05) total feed cost by 21%.

“…Indeed, Stević et al ( 2010 ) demonstrated that A. viridis leaves can have a tannin concentration of 44 ± 4 g kg −1 DM, which can form tannin-protein complexes by binding with plant proteins when consumed by livestock (Harris et al 1998 ; Waghorn 2008 ; Woodfield et al 2019 ). These complexes are better protected from rumen microbial degradation and they can thus reduce the degradation of N during digestion (Waghorn et al 1987 ; Burggraaf and Snow 2010 ; Piñeiro-Vázquez et al 2017 ). Therefore, the passage of undegraded N could be favored through the intestine and through dung, and a smaller proportion of N might be excreted in urine (Burggraaf and Snow 2010 ; Theodoridou et al 2011 ).…”

During the last decades, Alnus viridis has expanded over former montane pastures and meadows, due to land use and abandonment. This nitrogen-fixing woody species has triggered negative agro-environmental impacts, such as nitrogen (N) leaching, soil acidification and a reduced biodiversity. The aim of this study was to estimate the N translocation from A. viridis-encroached areas to adjacent open pastures by Highland cattle. In 2019 and 2020, Highland cattle herds equipped with GPS collars were placed in four A. viridis-encroached paddocks across Italy and Switzerland. The N content was measured in A. viridis leaves, herbaceous vegetation, and cattle dung pats, which were collected throughout the grazing season. Using GPS locations and collar activity sensors, livestock activity phases were discriminated. The N ingested by cattle was estimated through the N content of herbaceous vegetation and A. viridis leaves of vegetation patches visited by cattle during 24 h before dung sampling (N24H). The N content of herbaceous vegetation significantly increased with increasing A. viridis cover. The average N content in dung pats (31.2 ± 3.4 g.kg−1 DM) was higher than average values from literature on grazing cattle. Moreover, it was positively related to the N24H. Most of this N (29.5 ± 10.3 kg ha−1 yr−1) was translocated towards resting areas, which generally occurred on flat open pastures. Our results highlight the potential of Highland cattle to effectively translocate part of the ingested N from A. viridis-encroached towards targeted open areas, thus bringing new perspective for forage yield and quality improvement in the long-term.

“…No obstante, los TC presentes en Havardia albicans, Acacia pennatula y Bursera simaruba incorporados al 30% en la dieta, no afectaron la metanogénesis. Sin embargo, concentraciones de TC de entre 2 y 3% de la MS en la alimentación de novillas resultó en una reducción del 31% y 47 % de la pérdida de energía en forma de metano, sin afectar el consumo de MS y MO, aunque su digestibilidad se vio comprometida (Piñeiro-Vázquez et al, 2017).…”

Background. Worlwide ruminants are an important source of Greenhouse Gases (GHG) as they contribute with around 115 million tons of methane on a yearly basis. Methane is generated by the fermentation of the feed inside the rumen by a microbial consortia constituted by bacteria, archaea, fungi and protozoa. Due to the warming power of methane, which is 28 higher than carbon monoxide, current research focuses on diminishing the emissions of this gas by domestic ruminants. The use of several species of tropical trees and shrubs as a supplement of ruminant feed have resulted ideal within silvopastoral systems. Objective. To analyze the current research on trees tropical foliage through the implementation of silvopastoral systems in conventional livestock systems with the aim to diminish GHG generated by ruminal fermentation. Methodology. The search of bibliographic information was performed during august 2018 and june 2019 using key terms. Results. The results from the diverse research shows that foliage from trees and shrubs located in tropical regions not only increase livestock performance, but al so diminish methane synthesis within the rumen due to the action of derived plant secondary metabolites such as condensed tannins, phenolic compounds, essential oils, flavonoids and saponins present in leaves and pods. Implications. The information presented in this paper focuses on the use of foliage of tree and shrub species with forage potential in tropical conditions, which have a significant effect on the reduction of methanogenesis in ruminants due to an improvement in nutritional quality of the diet and the presence of secondary metabolites Conclusion. The use of silvopastoral systems with tropical legumes species have the potential of reducing the GHG produced by cattle by 20 up to 38 %.
