“…A low correlation coefficient between DMI and rumination was also noted in a previous study (Byskov et al, 2017). Nonetheless, Leiber et al (2016) found a higher correlation (r = 0.84) between daily rumination and DMI as long as the individual cow was included as a random factor. When the same model was calculated without cow as a random factor, it revealed a very low coefficient correlation between rumination and DMI.…”

This study aimed to identify individual characteristics differing among high-efficiency (HEf; upper 20%, n = 31), low-efficiency (LEf; lower 20%, n = 31), and mid-efficiency (MEf, 60% n = 93) lactating cows. Primiparous (37) and multiparous (118) high-producing milking cows at 30 to 180 d in milk were fed individually a low-roughage diet [31.6% of dry matter (DM)] for 4 wk. Daily average DM intake, rate of eating, visit duration, meal size, and daily rumination time were higher in LEf compared with HEf cows. On the other hand, HEf cows exhibited higher digestibility of DM, crude protein, and neutral detergent fiber than the LEf cows. Daily eating time was similar in the HEf and LEf groups and higher than that of the MEf cows. Visit and meal frequency, average visit and meal duration, daily lying time, and pedometer activity were similar in the HEf, LEf, and MEf groups. The HEf cows produced 1.75% more milk, but similar energy-corrected milk compared with the LEf cows. Milk fat and protein content were lower by 1.8 and 3.8%, respectively, in the HEf cows than in the LEf group. Body weight (BW) and BW gain were similar in the 3 efficiency groups. Diurnal distribution of DM intake showed 6 distinct major meals, each composed of 1.1 to 1.6 visits. Higher intake peaks (greater meal size) were found in the LEf cows compared with the HEf group. Daily DM intake was highly correlated (affected) with energy-corrected milk production (r = 0.61), BW (r = 0.4), eating rate (r = 0.57), and visit size (r = 0.54). Energy balance showed that the lower efficiency of the LEf cows was attributed to their excess heat production and energy loss.

“…Another characteristic suggested for predicting DMI is daily rumination and chewing time (Leiber et al, 2016). Unfortunately, a lack of knowledge exists regarding the effect of rumination and digestibility characteristics on the efficiency of high-yielding dairy cows.…”

“…Different from our previous study, where feeding high‐quality hay rich in WSC in combination with concentrates decreased rumination (Kleefisch et al, ), no diet effects were found in the present experiment, probably because the level of NDF intake was high in general (Beauchemin & Buchanan‐Smith, ). Time spent ruminating and daily numbers of boluses regurgitated were in the range observed also by others using the same RumiWatch System (Leiber et al, ), while time spent eating was longer in the present study, although DM intake level was similar as observed by Leiber et al (). A possible explanation for this discrepancy might be the different versions of evaluation software used (RumiWatch Converter 0.7.3.2 and RumiWatch Converter 0.7.3.11; Rombach, Münger, Niederhauser, Südekum, & Schor, ).…”

Forages rich in water-soluble carbohydrates (WSC) might be an ideal energy source during early lactation, as they provide both energy for milk production and structural fibre to promote chewing and rumen buffering. Thus, the aim was to investigate feeding strategies based on high-quality hay rich in WSC with graded amounts of concentrate on ruminating behaviour, ruminal pH and systemic health variables.Twenty-four Simmental cows were randomly allocated to four groups beginning 10 days before until 28 days after calving. Diets were 60LQH (60% fibre-rich hay plus 40% concentrate), 60HQH, 75HQH and 100HQH (60%, 75% and 100% highquality hay, plus 40%, 25% and 0% concentrate, respectively). Hay qualities differed in contents of WSC (110 g vs. 198 g of dry matter [DM]), neutral detergent fibre (646 g vs. 423 g of DM) and crude protein (65 g vs. 223 g of DM). Rumination was recorded using the Rumiwatch system over 4 days during the last week. Weekly serum samples were analysed for the liver enzymes aspartate aminotransferase, glutamate dehydrogenase and γ-glutamyltransferase and the acute phase proteins serum amyloid A and haptoglobin. Four cows per group received a wireless pH sensor orally placed into the rumen one week before the expected calving date. Daily time spent chewing did not differ between groups. Likewise differences in minimum, maximum and mean pH-values were not significant, but daily time of reticular pH <6 was longer in cows fed 60LQH compared to cows fed 100HQH (p = 0.043) and in tendency to cows fed 75HQH or 60HQH (p = 0.072 or p = 0.086, respectively). Blood parameters were unaffected by diet. Accordingly the present results demonstrate that feeding hay rich in WSC helped stabilizing the reticuloruminal pH in early lactation dairy cows, even in combination with 40% concentrates in DM.

“…In particular, compact electronic equipment for continuous monitoring of feeding and locomotion behavior provide reliable data at ever lower costs [ 20 ]. RumiWatch system is a sensor monitoring system widely used indoors [ 21 , 22 ]. Despite the fact that it was recently proposed for grazing assessment [ 23 , 24 ], to our knowledge, no papers have reported its application in evaluating the effect of different management strategies on feeding behavior.…”

Simple SummaryTraditional Alpine husbandry systems require dairy cows to be grazing on mountain pasture during summer and kept indoors during the remaining part of the year. Nowadays, the pasture is not able to fully satisfy the nutritional requirements of cattle; therefore, the use of concentrates is frequently required. From their use, some issues arise: the cows tend to consume the concentrates at the expense of the grass; concentrates are competitive with human diets; concentrates decrease the environmental sustainability of farm. Therefore, in order to minimize their use, it is imperative to obtain data on the grazing behavior of cows. The aim of this study was to assess the effect of concentrate levels on the behavior of dairy cows during summer grazing in two pastures characterized by Poion alpinae and Seslerion caeruleae alliance. Cows were equipped with an electronic device to evaluate feeding behavior (grazing, rumination, and walking). In addition, the plant selection by animals was assessed. In Poion alpinae, a rich pasture, the increased supplement influenced the selectivity of the pasture species, while in Seslerion caeruleae, a poor pasture, supplementation resulted in a reduction in grazing times. The study highlights how the supplement level induced a different grazing behavior depending on pasture type.AbstractDuring grazing on Alpine pastures, the use of concentrates in dairy cows’ diet leads to a reduction of the environmental sustainability of farms, and influences the selective pressure on some plant species. In order to minimize the use of concentrates, it is imperative to obtain data on the grazing behavior of cows. The aim of this study was to assess the effect of concentrate levels on the behavior of dairy cows during grazing. One hundred and ten lactating Italian Simmental cows, that sequentially grazed two pastures characterized by Poion alpinae (Poion) and Seslerion caeruleae (Seslerion) alliance, were considered. For each pasture, eight cows were selected and assigned to two groups: High and Low, supplemented with 4 kg/head/d, and 1 kg/head/d of concentrate respectively. Cows were equipped with a noseband pressure sensor and a pedometer (RumiWatch system, ITIN-HOCH GmbH) to assess grazing, ruminating, and walking behavior. In addition, the plant selection of the animals was assessed. On Poion, increased supplement intake caused a more intense selection of legumes, without affecting feeding and walking times. On Seslerion, grazing time was higher in Low than High. Grazing management in alpine region must take into account the great variability of pastures that largely differ from a floristic and nutritional point of view.
