And Performance

We studied the behavior and performance of wapiti on aspen parkland ranges in central Alberta after a winter in which one group received a pelleted alfalfa–barley supplement and another served as a control, on an unsupplemented diet. Wapiti that were lighter at the end of winter because they were young or because they did not receive nutritional supplementation grew faster on summer pasture. This compensatory gain was not explained by any one factor. Intake rates, bite rates, bite sizes, and diet selectivity varied by habitat and date, but did not differ consistently between wapiti receiving supplemented and unsupplemented diets. Irrespective of winter nutrition treatment, wapiti apportioned feeding time to different habitats in relation to foraging returns. However, by feeding longer, those on an unsupplemented diet consumed more forage during the spring flush in mid-April, and over all time periods, lighter individuals consumed more relative to body weight. Diet digestibility as a consequence of either greater forage selectivity or digestive efficiency was unaffected by nutritional history. Resting metabolic rates increased from 495 kJ∙kg−0.75∙d in late winter to 641 kJ∙kg−0.75∙d in summer, but were not significantly related to compensatory gain or reproductive status.

Reproductive Activities

The relationship between resources (forage availability and quality) and the foraging dynamics of muskoxen, Ovibos moschatus, was studied in Angujaartorfiup Nunaa, western Greenland, during spring (calving, post calving), summer, autumn (rut), and midwinter. Muskoxen did select among vegetation types in all seasons but calving. During the postcalving period, summer, and rut, the vegetation types meadow, moist dwarf shrub heath, and grassland were preferred, whereas meadow, moist dwarf shrub heath, and steppe were selected during midwinter. The relative availability of graminoids in vegetation types did not correlate with selection of vegetation types. Seasonal patterns of daily feeding time were negatively correlated with forage quality, whereas no correlation with forage availability was found. Seasonal rumination times were negatively correlated with both availability and quality of forage. The length of rumination time is apparently not solely explained by variations in forage quality. Results presented here indicate that rumination time is also a behavioural strategy of muskoxen. Movement rates did not correlate with forage availability. During midwinter, muskoxen did not respond to low forage quality by increasing daily feeding time as was seen during calving. Instead, an energy-conserving strategy was observed, where a relatively larger proportion of time was allocated to resting, i.e., nonruminating. Bachelor herds and mixed herds differed in daily feeding time and habitat use during the prerutting and rutting season. Prior to the rutting season, muskox bulls increased energy intake to compensate for the subsequent allocation of time to reproductive activities. During the short arctic growing season, muskoxen in western Greenland decreased daily feeding time, whereas those in eastern Greenland increased feeding time. This difference in foraging dynamics is hypothesised to be a result of differences in biotic and abiotic constraints imposed on muskoxen in these two regions.

Randomized Design

In order to evaluate the performance of Nile tilapia (Oreochromis niloticus), daily feeding amounts were varied in an experiment following a completely randomized design for 154 days and consisting of four treatments with three replications each, totaling 12 tanks with 3 m3 (3 x 1 x 1 m) of area each at densities of 5 fish m-3 (initial) and 3 fish m-3 until the end of the experiment. Throughout the experimental period, the daily amount of feed was varied and delimited for each feeding time (8h00, 11h00, 14h00 and 17h00) as: 25; 25; 25 and 25% in daily treatment 1 - T1; 20; 30; 30 and 20% in treatment 2 - T2; 30; 20; 20 and 30% in daily treatment 3 - T3; and 20; 30; 20 and 30% in treatment 4 - T4. Feed was offered six days a week, with extruded isocaloric (1,412 KJ) and isoproteic (32% crude protein) diets from 2 to 4 mm. Every two weeks, a sample containing 30% of stocked individuals was collected in each replication to monitor fish growth. Nile tilapia (O. niloticus) fed in daily amounts of 20; 30; 20 and 30% showed a better growth performance in the final of experiment, mainly on biomass, final average weight and feed conversion.

Sorghum Grain

Digestibility comparisons were made between whole and rolled sorghum when pigs were fed either ad libitum or at restricted levels. The method of restriction was to limit each of two daily feeding periods to 15 minutes. The organic matter and N.F.E. digestibility coefficients were higher for rolled grain than for whole grain. Restriction of feeding time had no significant effect on digestibility coefficients of rolled grain. The data indicate a tendency for digestion to be poorest when whole grain is given for restricted feeding periods.

Free Running Period

Phase setting of the circadian rhythm by restricted daily feeding (RF) was examined in rat pups. Feeding of virgin, pregnant, and nursing rats together with pups was restricted to 4 h at a fixed time of the day. Phases of the circadian rhythm developed in neonatally blinded pups were measured on the day of weaning to evaluate the effect of RF on phase setting. The activity onset and offset of the locomotor rhythm were used for the phase reference. In blinded pups born and raised under ad libitum feeding, the phase at weaning was a function of the free-running period measured after weaning and located in a narrow range (control zone). When RF was imposed from 2 wk prior to the conception (C) until weaning (3w), the pups phases were located outside the control zone and related to the feeding time. To identify the period in which the phase setting is effective, RF was imposed during 5 different periods (C-0w, C-1w, C-2w, 2-6w, and 3-6w). The circadian rhythm of all pups in the C-2w group and some in the C-1w was phase set, but those in other groups were not affected. It is concluded that RF imposed during the early nursing period is capable of phase setting the circadian system of blinded infant rats.x

The objective of this study was to determine the effect of close-up diets with increased ratios of neutral detergent fiber (NDF) to non-fibrous carbohydrates (NFC) on feeding behavior in transition cows. Thirty-nine dry cows were blocked, assigned randomly to three groups and fed diets with a low (1.07, LF), medium (1.41, MF) or high (2.08, HF) NDF:NFC ratio from 21 d prior to the expected day of calving. After parturition, all cows were fed the same diet for a further 35 d. The average DMI decreased as the ratio of NDF:NFC increased at -3 weeks (Wk) and -2 Wk and increased at +5 Wk plessthan 0.05). The average daily feeding time was lower and the average feeding rate was higher (plessthan 0.05) for LF cows compared with MF and HF cows during prepartum. In conclusion, a prepartum diet with increased ratios of NDF:NFC decreased the DMI and feeding rate, increased daily feeding times and visits prepartum and was beneficial in increasing DMI postpartum.
