“…The number of meals per day observed in the present experiment was similar to the 10.6 meals per day reported by Dado and Allen (1993), and the 10.9 meals reported by Oba and Allen (2000). Others (Vasilatos and Wangsness 1980;Cassida and Stokes 1986) reported a range of 9 to 14 meals d -1 for dairy cows fed TMR diets. It appears that the number of meals per day may be influenced by a variety of factors, including diet composition.…”

“…7), as shown in previous studies (Heinrichs and Conrad 1987;Gill and Romney 1994;Tolkamp et al 2000). Cows spent more time eating during the afternoon (1500 to 2100) than from midnight to early morning, confirming previous reports for beef cattle (Putnam et al 1964) and dairy cows (Vasilatos and Wangsness 1980;Bermudez et al 1989;Morita et al 1996). Beauchemin (1991) reported that cows spent most of the time eating during daylight hours, and for cows with high intakes, as much as 30% of total intake occurred at night.…”

“…Wangsness et al (1976), working with sheep fed a complete ration composed of 20% chopped hay and 80% concentrate, reported a positive relationship between meal size and meal duration (r = 0.49). In contrast to our observations, a negative correlation between meal duration and the number of meals was reported previously for dairy cows fed TMR (Vasilatos and Wangsness 1980). Meal size was also positively related to eating rate, but the relationship was curvilinear.…”

“…In that study, dairy cows were offered a TMR consisting of 29% alfalfa silage, 29% corn silage, and 42% concentrate (DM basis). Furthermore, Vasilatos and Wangsness (1980) found no relationship between DMI and the number of meals each day for dairy cows fed a TMR containing 60% concentrate. The number of meals per day observed in the present experiment was similar to the 10.6 meals per day reported by Dado and Allen (1993), and the 10.9 meals reported by Oba and Allen (2000).…”

. 2002. Effect of diet and parity on meal patterns of lactating dairy cows. Can J. Anim. Sci. 82: 215-223. Four multiparous and four primiparous lactating dairy cows housed in stalls were used in a double 4 × 4 Latin square to determine the effect of parity and diet on meal patterns. Cows were fed one of four diets: three total mixed rations containing 40, 50, or 60% barley silage on a dry matter (DM) basis, and a diet in which forage and concentrate were allocated separately (SI) containing 50% concentrate. Dry matter intake was similar for all diets (18.2 ± 0.6 kg d -1 ), as were the number of meals per day (10 ± 1 meals d -1 ) and meal duration (35 ± 3 min meal -1 ). Meal size was larger (5.2 vs. 1.1 or 1.9 kg DM meal -1 ), and eating rate was faster (0.265 vs. 0.053 or 0.034 kg DM min -1 ) when cows consumed concentrate, compared with silage or TMR, respectively. Meal size of TMR, silage or concentrate was positively related to DM intake (r = 0.82, 0.76, and 0.98; respectively). For cows consuming TMR, the number of meals per day was negatively related to DM intake (r = -0.41). Dry matter intake increased when meal size increased, primarily as a result of longer meals and, to a lesser extent, faster eating rate. Feeding management had little effect on meal patterns. Multiparous cows tended to eat more in each meal compared with primiparous cows, but both groups spent the same amount of time eating per meal. . La prise de matière sèche était identique dans tous les cas (18,2 ± 0,6 kg par jour), comme le nombre de repas par jour (10 ± 1) et la durée du repas (35 ± 3 minutes par repas). Les portions étaient plus importantes (5,2 c. 1,1 ou 1,9 kg MS par repas) et la consommation plus rapide (0,265 c. 0,053 ou 0,034 kg MS par minute) chez les vaches nourries de concentré que chez celles recevant de l'ensilage ou une RTM, respectivement. On a établi une corrélation positive entre la grosseur de la portion de RTM, d'ensilage ou de concentré et l'absorption de MS (r = 0,82, 0,76 et 0,98, respectivement). Chez les vaches nourries de RTM, on remarque une corrélation négative entre le nombre quotidien de repas et l'absorption de MS (r = -0,41). La prise de matière sèche augmente avec la grosseur de la portion, principalement parce que le repas dure plus longtemps et, dans une moindre mesure, parce que les animaux mangent plus vite. La gestion du régime n'a pas une grande incidence sur les habitudes alimentaires. Les vaches multipares ont tendance (P = 0,17) à consommer plus que les vaches primipares à chaque repas, mais les deux groupes passent autant de temps à manger.

“…It has been previously reported that cattle fed in a barn have an average number of 12.1 meals per day (Vasilatos and Wangsness, 1980), or, according to Dado and Allen (1994), around 11 feeding periods per day. Also, an average total feeding time of 253.6 min d −1 (Vasilatos and Wangsness, 1980) or 301.0 min d −1 (Dado and Allen, 1994) was reported for cows held in a barn and fed ad libitum. In this study the individual visits to the feeding trough and the total time spent feeding were recorded automatically by the RIC sys-tem.…”

Abstract. The aim of this study was to determine whether feed intake amount and feed intake behaviour could be related to oestrus in dairy cows. Furthermore, we investigated whether oestrus had an effect on daily milk yield. A total of 138 oestrus cycles, leading to conception of 100 cows, were analysed. The parameters "daily fresh matter intake amount (kg)", "daily number of visits to the feeding trough" and "time spent feeding per day (min)" were electronically measured and recorded. For a sub-quantity of all animals, daily milk yield (kg) was recorded continuously and stored in the herd management software. Special attention was given to the day of oestrus, which was defined as the day of successful insemination. All remaining days of the oestrus cycle were considered as the reference period. Among all animals and cycles, fresh matter intake amount per day, number of visits per day, and time spent feeding per day were reduced by 10.3, 9.1 and 20.8 %, respectively, on the day of oestrus. Fresh matter intake was significantly lower in primiparous cows than in multiparous cows. However, number of visits to the trough and time spent feeding per day were significantly higher in primiparous cows compared to multiparous cows. Day of oestrus did not have a significant effect on daily milk yield, as this parameter was characterized by high variation among all days of the oestrus cycle. In conclusion, if an RIC system is used, monitoring of feeding behaviour appears to be a potential auxiliary aid in oestrus detection.
