Abstract: Nutritional assessment of grazing ruminants, particularly on natural heterogeneous rangelands, remains a challenge for researchers and technicians. The aims of this study were: i) to compare methodologies of herbage sampling to determine crude protein (CP) and digestible organic matter (DOM) contents of ingested herbage and, ii) to evaluate the use of faecal near-infrared reflectance spectroscopy (fNIRS) to estimate those herbage attributes using either sampling procedure. Herbage samples were collected through hand-clipping (HC) or directly from rumen extrusa at the beginning (ExBM) and at the end (ExEM) of the longest daily sheep meal. In addition, DOM content of ingested herbage was also calculated from the amount of N excreted in faeces (FN). The study was conducted throughout thirteen consecutive months with six rumen-cannulated male sheep kept free on a rangeland plot in southern Brazil. Monthly, data on diet CP and DOM contents were collected by either method and related to near-infrared spectra of faeces collected from each respective sheep using the partial least squares method. Crude protein content in herbage ingested by sheep ranged from 108 to 172?g/kg DM and was, on average, lower (P?MenosAbstract: Nutritional assessment of grazing ruminants, particularly on natural heterogeneous rangelands, remains a challenge for researchers and technicians.

Crude protein content in herbage ingested by sheep ranged from 108 to 172?g/kg DM and was, on average, lower (P?<?0.05) in ExEM than in either ExBM or HC samples. Digestible organic matter content of ingested herbage, estimated through rumen in situ incubations, ranged from 546 to 717?g/kg DM and was, on average, similar for ExBM, ExEM, and HC samples. However, when this variable was estimated through the FN approach, values ranged from 446 to 601?g/kg DM and were, on average, lower (P < 0.05) than those found through other methods. The fNIRS models based on data obtained through extrusa (EX) and HC procedures produced similar and reliable results for estimating CP of herbage ingested by sheep, whereas the FN approach yielded the best fNIRS model for estimating DOM content of herbage.

Nutritional warning helps promote healthy choices. In Brazil, the black magnifying glass is utilized when added sugars are ≥7.5% in beverages. To avoid this warning, the food industry uses apple juice to replace added sugar, informing consumers through package claims. However, the impact of this information on consumer product perception remains unclear. This study evaluated the effect of product formulation, warning ("High in added sugar"), and claim (“With apple juice”) on consumers' expected liking and intention to purchase fruit nectars. Six packages were developed following an incomplete factorial design with three factors (levels): (i)Product (Mixed grape and apple nectar no sugar; Grape nectar with sugar; Mixed grape and apple nectar with sugar), (ii)Claim and (iii)Warning (Present/Absent). Consumers (n=100) looked at the packages and evaluated the expected liking (9-point hedonic scales) and purchase intention (5-point scales). Additionally, participants expressed their agreement (7-point Likert scale) on the ways for sweetening nectars: using sugar, apple juice, or sugar and apple juice. Product affected the expected liking. Lower averages were observed for “Mixed grape and apple nectar no sugar”, without warning, with claim (6.7±1.5) or without (6.6±1.6); and “Mixed grape and apple nectar with sugar”, with warning, and with claim (6.8±1.5) or without (6.7±1.4) compared to “Grape nectar with sugar”, with warning, with or without claim (7.6±1.3; 7.8±1.4). Purchase intention demonstrated similar results. The factor "Product" contributed to a greater expected acceptance, even in the presence of "Claim" and "Warning" (both didn’t affect acceptance). Participants gave a higher score to apple juice as a suitable way to sweeten nectars (average=5.1), as opposite to sugar or apple juice and sugar suggesting a dichotomy between the expected liking by looking at the nectar package and a question that was answered requiring rational thinking. Further studies are necessary to comprehend the consumer's perception/preference, sugar replacement, and warnings. MenosNutritional warning helps promote healthy choices.
