“…Table 2 revealed that ewes lambs essentially exhibited similar patterns of N-BJMRs, TSB and TJM, regardless of the remarkable differences in residues heights (Table 1). Similar results were reported by Yayota et al (2015). It can be inferred that ewe lambs did not need to perform more harvesting movements or manipulate the harvested material since these variables remained constant (Table 1).…”

“…Bite Rate, N-BJMRs and BM determine STIR (YAYOTA et al, 2015), as shown in experiment 1, in which there was no difference in variables BR, N-BJMRs among treatments. It is worth noting the trend (p = 0.055) for the treatment of BM 14 cm (Table 1).…”

“…The BR was higher for the PMCR of 15 cm, leading to a higher STIR, compared to 45 cm indicating that the largest residue reduced the BR (Figure 1). The relationship between BR and STIR was observed in Yayota et al, (2015). Moreover, BR includes the time spent searching (locomotion, recognition and decision) and handling food (PRACHE, 1997).…”

“…However, had the herbage allowance been more limiting, there may have been greater contrasts in the behavior related to the sward structure or grass species. Alternatively, using the sward height alone as a predictor of the DMI is not without risk, for if the sward structure is such that the top canopy is sparse [19,38,39], the DMI may still be limited.…”

Relationship between Temperate Grass Sward Characteristics and the Grazing Behavior of Dairy Heifers

Sward architecture mediates ruminant grazing behavior in temperate grazing lands. Temperate grasses differ in their sward structure, which may influence the grazing behavior of cattle. We determined relationships between the grazing behavior of dairy heifers and the sward structure of the following temperate grasses: meadow fescue (Schedonorus pratensis (Huds.) P. Beauv.), orchardgrass (Dactylis glomerata L.), quackgrass (Elymus repens (L.) Gould), and reed canarygrass (Phalaris arundinacea L.). Vegetative-stage grasses were rotationally grazed by Holstein heifers (average initial body weight of 460 kg) during 5 day periods in the spring, summer, and fall of 2007 and 2008. The herbage dry matter (DM) allowance was twice the expected daily intake (11 kg DM animal−1 d−1). The sward characteristics were measured before grazing (e.g., the herbage height and mass, vertical distribution of leaf and stem fraction, and nutritive value). The grazing behavior of the heifers was quantified using automatic jaw movement recorders. In this study, the grass species had little effect on the grazing behavior. However, the bite rate was negatively correlated with the herbage mass, while the number of bites was positively correlated with the sward height and herbage mass. These results suggest that when herbage availability is not limited, grazing dairy heifers exhibit similar ingestive and rumination behavior across grass species and seasons, yet jaw movement dynamics may respond to the different characteristics of the swards. The results of this study provide the following benefits: (1) they inform managers about the jaw movement mechanics that can be expected of dairy heifers in temperate forage systems, showing that they are not limited by herbage allowance, and (2) they provide insight for future studies that employ on-animal sensors to evaluate foraging dynamics and animal performance outcomes in temperate forage pasture systems.

“…At coarse scales, both abiotic factors, such as topography and temperature, and biotic factors, including forage quality and quantity, constrain the intake rate via animal movement patterns (Bailey & Provenza, 2008). At fine scales such as the bite scale, the instantaneous intake rate is the consequence of grazing jaw movements, which interact with sward characteristics such as height, bulk density, and morphology (Black & Kenney, 1984; Boval & Sauvant, 2019; Flores et al, 1989; Laca et al, 1994; Yayota et al, 2015). Specifically, the instantaneous intake rate of herbage is determined by bite mass and bite rate.…”

This study aimed to clarify the differences in ingestive behavior between goats and sheep at the bite scale. Animals were allowed to graze a feeding station of bahiagrass (Paspalum notatum Flügge) with two sward heights (short and tall) to two levels of bite depletion (20 and 40 bites). Ingestive behavior variables, which represent the rate and mass of bites and chews, intake rate, bite dimensions, and bite placement characteristics, were quantified. The interspecies difference in ingestive behavior became obvious at the short sward. Goats reduced the inter‐bite distance and maintained bite overlapping but took deeper bites than sheep at the short sward, resulting in slightly greater bite mass. These behavioral changes with efficient chewing may be helpful to maintain the intake rate at the short sward. Sheep maintained their inter‐bite distance regardless of the sward height and decreased overlapping bites at the short sward. These behavioral characteristics in sheep in response to sward height may partly compensate for the decrease in the bite mass at the short sward, although it may not always maintain the intake rate. Thus, the present study suggests that goats and sheep implement different bite scale ingestive behaviors, including bite placement, when they eat short swards.
