“…For example, even though milk yield was lowest for the shortest pasture access length in experiment 1, with the lowest grazing time perhaps efficiency of production was enhanced by a lower grazing activity energy cost. This is supported by some findings of Keli et al (2017) with lactating Alpine goats subjected to a continuous access treatment compared with ones in which access was limited. Heat energy was greatest among treatments for the control treatment in nearly all hours of the day, perhaps because of the greatest time spent grazing and walking, despite the lowest distance travelled.…”

“…Possibly because grazed forage constituted a relatively low proportion of the diet (i.e. 34.8-48.8%) in the study of Keli et al (2017), time spent grazing of 5.9-7.4 h was less than in the second experiment of Charpentier and Delagarde (2018) and the rate of DM intake was only 1.5-2.0 g/min. Results such as these suggest that if given free or relatively long access, lactating dairy goats spend more time eating than necessary.…”

“…Natural pasture, as compared to cultivated pasture, is a renewable alternative with no energy opportunity cost in terms of human food. Given the potential positive relation between the use of pasturable resources and energy efficiency in pastoral husbandry systems [49], the indicator measuring the dependence of livestock breeding systems on external feed becomes relevant. In the present case study, this indicator is estimated at 66.8% for F1, revealing a high level of external dependence because only 33.2% of the animal feed consumed in the system comes from resources with no opportunity cost in terms of human food.…”

“…The results also disagree slightly with those of Keli et al (2017). In that experiment, lactating dairy goats were allowed to graze pastures continuously or between the morning and afternoon milkings or when leaf surfaces were dry until the afternoon milking or sunset.…”
