“…In contrast to findings of Tsukahara et al (2014) with growing meat goat wethers, clear benefits in terms of level or efficiency of production from limited feeder access treatments were not readily apparent. The results also disagree slightly with those of Keli et al (2017).…”

“…Tendencies for HE to be less for 2Hour and 4Hour than for Control, Day, and Night treatments is somewhat in agreement with findings of Tsukahara et al (2014) for Boer goats. In that study, continuous feeder access resulted in high ADG but relatively inefficient feed utilization, which was thought to be associated with longer total time spent in the automated feeders than goats with restricted feeder access regimes.…”

“…However, there have been some findings from studies with goats suggesting that efficiency of production could be greater with restricted periods of access (Berhan et al 2005;Patra et al 2008aPatra et al , 2008bTovar-Luna et al 2011;Tsukahara et al 2014;Keli et al 2017). As an example, in the study of Tsukahara et al (2014), growing Boer goat wethers were given different periods of access to an automated feeder with a 50% concentrate pelleted diet. Continuous feeder access facilitated high average daily gain but resulted in relatively inefficient feed utilization as assessed by residual feed intake.…”

“…Two of the restricted feed access treatments used by Tsukahara et al (2014) of relevance to dairy goats in confinement or drylot-based production systems are access either during the day or night between milking times in the morning and afternoon. Other treatments of interest are 1-or 2-h access periods after morning and afternoon milking for total daily feed access of 2 or 4 h/day, respectively, which would be convenient for management considerations such as close observation of feeding behaviour to monitor health conditions.…”

Fifty Alpine goats at 125 ± 3.0 days-in-milk were given access in Calan gate feeders to a 40% forage diet for 12 wk continuously (Control), during daytime (Day) or night (Night), or for 2 or 4 h/day after milking in the morning and afternoon (2Hour and 4Hour, respectively), resulting in few significant effects. In a second 12-wk experiment, average daily gain (ADG) by 40 Alpines at 14 ± 0.7 days-in-milk (73, 39, 11, 24, and 21 g) was greater for Control than for the average of other treatments, milk yield was similar among treatments, milk fat was lower (P = .089) for Control (3.41%, 3.88%, 4.21%, 3.70%, and 3.49%), and milk energy was not affected (8.20, 7.36, 9.53, 8.56, and 6.91 MJ/day for Control, 2Hour, 4Hour, Day, and Night, respectively). Metabolizable energy intake (31.25, 22.69, 25.92, 26.69, and 23.46 MJ/day) and heat energy (17.51, 13.34, 14.09, 15.54, and 15.25MJ/day) were greater and milk energy relative to ME intake was lower for Control (26.0%, 31.9%, 37.6%, 31.4%, and 30.0% for Control, 2Hour, 4Hour, Day, and Night, respectively). In conclusion, continuous diet access of dairy goats in early to mid-lactation can affect partitioning of nutrients between milk synthesis and tissue accretion differently than some restricted feeder access treatments.

“…But it should be noted that feed consumption was measured on a daily basis, and differences in rate of intake among hours of the day are possible. Relatedly, in some instances ruminants spend more time eating than necessary based on studies with unrestricted and limited feeder access treatments, which can influence level of performance and efficiency of feed utilization (Tovar-Luna et al, 2011a;Tsukahara et al, 2014;Keli et al, 2017).…”

Fifty-four Alpine doelings (initial BW and age of 31.7 ± 0.38 kg and 306 ± 1.9 d, respectively) were allocated to nine treatments individually fed for ad libitum intake of 25% concentrate and 75% forage diets (DM basis). Alfalfa was the forage in the control diet. Other diets contained Sericea lespedeza as the forage, with 1.25% DM of quebracho extract included in the concentrate fraction for a dietary condensed tannin level of 8.4%. Lespedeza treatments were no additive (L) and inclusion of monensin (I) at 22 mg/kg DM (L-I), soybean oil at 3% (L-S), coconut oil at 3% (L-N), I and 3% soybean oil (L-IS), I and 3% coconut oil (L-IN), 1.5% soybean oil and 1.5% coconut oil (L-S-N), and I, 1.5% soybean oil, and 1.5% coconut oil (L-IS -N). The experiment was 12 wk with two 6-wk periods. Gas exchange was determined in weeks 6 and 12, and other measures occurred in weeks 5 and 11. The control diet offered averaged 2.67% nitrogen, 43.8% neutral detergent fiber, and 8.8% acid detergent lignin, and the L diet offered averaged 2.03% nitrogen, 42.8% neutral detergent fiber, and 13.2% acid detergent lignin. There were no treatment × period interactions for digestibilities (P ≥ 0.770) or methane emission (P ≥ 0.324). There were differences (P < 0.001) between the control treatment and diets with lespedeza in intake of
