“…Although some studies indicate that supplementation affects the daily number of bites because of the increased nutrient intake via supplementation (Santana et al, 2013;Stivanin et al, 2014), we found no significant differences in this variable between treatments ( Table 2). The movement rate (9.28 and 11.3 steps min -1 ) and the number of stations visited per min (6.99 and 7.33) reported by P. M. Martini et al (2017) and Rodrigues et al (2019) in cattle grazing sorghum were like those of our study.…”

The present study was developed at the Beef Cattle Laboratory of the Federal University of Santa Maria and evaluated the effect of three levels of concentrate supplementation (S 0.8, S 1.0, and S 1.2, corresponding to 0.8%, 1.0%, and 1.2% of bodyweight, respectively) on the ingestive behavior and movement patterns of 24 steers grazing on sorghum. The experiments were performed using a completely randomized block design in a 3 ? 3 factorial arrangement (three levels of supplementation ?three experimental periods), and the grazing time was evaluated using a 3 ? 24 factorial arrangement (three levels of supplementation ? 24 hours of observation). The steers fed S 0.8 presented longer(P=0.009) grazing time in the morning (241 min day-1) compared to animals fed S 1.2(172 min day-1). The number of bites per feeding station was higher (4.05) during the second experimental period, and the number of bites min-1 increased from 25.4 to 31.4 from the first to the second experimental period. The changes in sward structure during the growth stages of sorghum affected the number of bites per feeding station and the number of bites per minute.

“…This in turn promotes an increase in the duration of grazing, which may lead to a restriction of intake and the daily nutrient requirement not being met. Stivanin et al (2014) evaluated the ingestive behavior of hoggets which received different types of supplement on ryegrass pasture, and observed that the daytime grazing is shorter when the hoggets receive supplements, regardless of the type of supplement.…”

Comparison of protein and energy supplementation to mineral supplementation on feeding behavior of grazing cattle during the rainy to the dry season transition

et al. 2016

The aim of this study was to evaluate the effects of protein-energy or mineral supplementation on the ingestive behavior of dairy steers on pasture in the post-weaning phase during the rainy to dry season transition. Twenty-two ½ Holstein–Zebu dairy steers with an average initial body weight of 234 ± 16 kg were distributed into a completely randomized design into two groups: protein-energy supplementation and mineral supplementation offered ad libitum. The steers receiving protein-energy supplementation showed higher (P < 0.05) intake of dry matter (DM) and neutral detergent fiber (NDF) than those fed diets composed of mineral salt only. In addition, the animals that received protein-energy supplementation had longer period in grazing and spent on average more time per period eating at the trough (P < 0.05), however no significant differences were observed in the time per period in rumination and time per period in idle (P > 0.05). The supply of protein-energy supplement does not change the feeding behavior, except for an increase in the time spent feeding at the trough. The intake of protein-energy supplement improved the of DM and NDF feed efficiencies in grazing cattle during the rainy to the dry season transition.

“…Very long time intervals between grazing can compromise the forage nutrient value, canopy structure, livestock performance, and forage intake. In Italian ryegrass, its phyllochron values have been used as a reference to determine the intervals between grazing by applying the thermal sums concept; examples of reported thermal sums are 312.5 degree-day (DD;CoNFoRTIN et al, 2010;MACHADo et al, 2011), 250 DD (RoSA et al, 2015 and 187.5 DD (STIVANIN et al, 2014;MoTERLE et al, 2017).…”

The canopy structure and morphogenesis of ryegrass (Lolium multiflorum Lam.) was investigated after it was over seeded with Tifton 85 (Cynodon spp.) and intercropped with red clover (Trifolium pratense L.). Time intervals between cuts were determined by different thermal sums (125, 250, 375, and 500 degree-days [DD]). Cuts were conducted at a height equivalent to 50% of the average canopy height. Morphogenic and structural data were collected from July to October of 2016 and 2017, from a completely randomized block experimental design. Canopy height, extended tiller height, pseudostem length, and forage mass were fitted to linear equations according to the thermal sums. Interaction of ryegrass with red clover was the highest (12.1%) for longer cut intervals (375 and 500 DD). The leaf appearance rate (0.0080 leaf/DD), phyllochron value (128.8 DD), and senescence rate (0.10 cm/DD) of ryegrass were comparable between the different intervals. The slowest elongation rate (0.06 cm/DD) with the shortest interval duration between cuts (171.6 DD) was observed in the 125 DD interval. According to the findings from this 2-year experiment, the use of a 250 DD cut interval was recommended between grazing events, taking into account the efficiency of forage use, ryegrass leaf, stem ratio, and interactions with red clover in the canopy under rotational stocking.
