Abstract: A series of trials were conducted in different experimental and feeding conditions to evaluate a purified and enriched lignin extracted from Eucalyptus grandis (LIPE®) as a marker to estimate faecal output in sheep fed temperate and tropical grasses. Two indoor trials were conducted in metabolism cages: the first one (Trial I) was conducted with sheep fed Italian ryegrass (Lolium multiflorum Lam.) pastures, which was evaluated in two different periods [Period I (n =14), and Period II (n =15)], and the second one (Trial II) was performed with sheep fed pearl millet [Pennisetum americanum (L.) Leeke] pastures (n =16). Grazing trials were performed with sheep grazing Italian ryegrass [Trial III (n =62)] and pearl millet [Trial IV (n =34)]. According to the manufacturer?s statements, sheep were dosed once a day with capsules containing 250 mg of LIPE® for a period of seven days, beginning two days before total faecal collections started and finishing on the last faecal collection day. To measure the observed daily faecal output, sheep were harnessed with faecal bags that were emptied once a day at 0800 h for five days. Faecal subsamples from indoor and grazing trials were taken to determine the LIPE® content by infrared spectroscopy. Regression analyses performed between estimated and observed faecal output (g DM/kg LW/day) by sheep were not significant (p >0.05) in three of the four evaluated trials. Faecal LIPE® recovery from the total data of the four trials showed a statistical difference when compared to the reference value (100%). In conclusion, our results show that the LIPE® marker presents low accuracy to estimate the daily faecal output of sheep fed temperate (Italian ryegrass) and tropical (pearl millet) grasses.

The expansion of annual cropping systems and associated land cover changes may induce soil degradation, compromising the soil's ability to function and provide ecosystem services, also referred to as soil health (SH). Conservation practices may reduce SH decline, yet their benefits are uncertain. The main objectives of this paper were to apply a comprehensive SH assessment framework to evaluate (i) SH differences in natural grasslands and cropping areas, and (ii) how conservation practices lessen SH deterioration. Soils under natural grasslands were compared to cropped soils from three long-term experiments with treatments evaluating the effects of cover crops and/or pastures incorporation; no-tillage; and crop fertilization for Uruguayan Mollisols. Soil chemical (pH, cation exchange capacity, macro, and micro-nutrients), physical (wet aggregate stability, available water holding capacity, penetration resistance), and biological (organic carbon, active carbon, protein, respiration) indicators were measured. SH was significantly lower across all indicators under cropped areas than under natural grasslands, especially when soil fertility is not adequately maintained in cropping systems. Conservation practices lessened SH degradation, particularly soil biological properties, but had confounding benefits. Overall, gains in SH were linked to adequate soil fertility maintenance and longer active plant growth periods associated with including pastures and cover crops in annual cropping systems. /© 2022 The Authors.
